The continuous multi-direction independent sampling device can realize continuous multi-direction independent sampling of a plurality of agricultural products through the continuous sampling mechanism 2, when the continuous multi-direction independent sampling device is implemented, a plurality of agricultural products thrown into the outside are stored through the fixed storage cylinder 1, then the continuous sampling mechanism 2 can screen the agricultural products thrown into the fixed storage cylinder 1 and fix the screened agricultural products in the independent fixed cavities, then the continuous multi-direction independent sampling action is continuously carried out on each agricultural product in the fixed cavities through the continuous sampling mechanism 2 so as to implement continuous multi-direction independent sampling action, and finally the auxiliary processing mechanism 3 is used for preprocessing a taken agricultural product sample so as to obtain an agricultural product detection product.
As shown in fig. 1, 2 and 3, the continuous sampling mechanism 2 includes a screening disk 21 connected to the top end of the fixed storage cylinder 1 and used for screening a plurality of agricultural products thrown into the fixed storage cylinder 1, a spindle 22 driven by a driver is connected to the axis position of the screening disk 21 in a penetrating manner, one end of the spindle 22 close to the screening disk 21 is connected with a rotary wheel changing disk 23, the rotary wheel changing disk 23 is arranged on one side of the screening disk 21 close to the bottom of the fixed storage cylinder 1, one side of the rotary wheel changing disk 23 far away from the screening disk 21 is connected with a storage device 24 used for storing the agricultural products and pushed by the rotary wheel changing disk 23 to replace the current sampled agricultural products, one side of the storage device 24 far away from the rotary wheel changing disk 23 is connected with a cover sampler 25 used for sampling the sampled agricultural products in multiple directions, and one side of the cover sampler 25 far away from the storage device 24 is directly connected with the auxiliary processing mechanism 3.
In order to realize the action of continuous multidirectional independent sampling of a plurality of agricultural products, a plurality of agricultural products put into the fixed storage barrel 1 are screened by the screening disc 21, so that the agricultural products are independently stored in the storage device 24 according to the size, the spindle 22 is driven to rotate by the driver, the rotating spindle 22 drives the rotating wheel-changing disc 23 to rotate, the rotating wheel-changing disc 23 guides the cover barrel sampler 25 to move up and down to sample the single agricultural product in a multidirectional manner, meanwhile, the rotating wheel-changing disc 23 drives the cover barrel sampler 25 to rotate by taking the spindle 22 as the axis so as to replace the current sampling agricultural product and carry out the multidirectional sampling action on the next agricultural product, and the auxiliary processing mechanism 3 is driven to preprocess the taken sample so as to obtain an agricultural product detection product.
As shown in fig. 1, 6 and 3, the sieving plate 21 includes a blocking cover 211 connected to the top end of the fixed storage cylinder 1, a feeding and discharging square hole 212 is formed on the blocking cover 211, a fixed plate 213 (the connection mode of the fixed plate may be a threaded connection to facilitate subsequent waste material removal) connected to the inner wall of the fixed storage cylinder 1 is disposed on one side of the blocking cover 211 close to the fixed storage cylinder 1, a plurality of leaking holes 214 are annularly formed on the surface edge of the fixed plate 213, the inner diameters of the leaking holes 214 are arranged in a clockwise increasing trend (i.e., the rotation direction of the spindle 22 is also clockwise rotation), a guiding and feeding table 215 which is sleeved on the outer side of the spindle 22 and used for feeding agricultural products towards the leaking holes 214 is mounted on the surface of the fixed plate 213, and a pushing block 216 which is connected to the spindle 22 and used for pushing the agricultural products into the leaking holes 214 by being driven by the spindle 22 is disposed on one side surface of the blocking cover 211 close to the fixed plate 213.
In order to realize the purpose of screening a plurality of agricultural products according to volume, in the specific implementation, a plurality of agricultural products are directly thrown into the throwing and discharging square holes 212 (for convenience of throwing, a rolling chute corresponding to the leakage hole 214 can be arranged on the side wall of the guide feeding table 215), at the moment, the agricultural products directly slide to the edge of the fixed disc 213 along the guide feeding table 215, then the spindle 22 is driven to rotate by an external driver, the spindle 22 drives the pushing block 216 to move after rotating, then the movable pushing block 216 pushes the agricultural products to roll along the edge of the fixed disc 213, once the agricultural products roll into one leakage hole 214, at the moment, the agricultural products with larger volume are directly pushed by the pushing block 216 to move towards the next leakage hole 214, and the agricultural products with smaller volume are directly pushed into the leakage hole 214 by the pushing block 216.
As shown in fig. 1 and 3, an auxiliary ring block 2141 is installed in the leakage hole 214, the auxiliary ring block 2141 includes a plurality of pushing blocks 2142 having a V-shaped longitudinal section, a pushing member 2143 connected to the inner wall of the leakage hole 214 is installed on the inner wall of the V-shaped opening of the pushing blocks 2142, and a guiding groove 2144 for limiting the pushing blocks 2142 is formed on the inner wall of the leakage hole 214;
the side wall of the pushing block 216 is connected with a deflection block 217, the side wall of the deflection block 217 is provided with a plurality of pushing rubber rings 218, the side wall of one end, far away from the pushing block 216, of the deflection block 217 is provided with a pushing piece 219 connected with the pushing block 216, and the pushing piece 219 (an elastic column can be selected, such as a spring column, and a rubber column can be selected) is used for applying movable pushing force to the deflection block 217, so that when the deflection block 217 contacts with agricultural products, the phenomenon that the agricultural products are pushed up by the agricultural products with larger volume to cause overlarge pressure applied to the agricultural products or the agricultural products are not contacted to cause the agricultural products to be incapable of entering the leaking holes 214 with the volume corresponding to the agricultural products is avoided.
In order to prevent the agricultural product from being stuck in the leaking hole 214 and cut by the edge of the leaking hole 214, in the implementation, once the agricultural product enters one leaking hole 214, the agricultural product will contact the pushing block 2142 one step first, at this time, the agricultural product will push the pushing block 2142 slightly to move towards the guiding groove 2144, at the same time, the top pressing member 219 will push the deflecting block 217 and the pushing rubber ring 218, so that the pushing rubber ring 218 gives a downward pressure to the agricultural product, then the downward-pressed agricultural product will push the pushing block 2142 directly to move further towards the guiding groove 2144, at the same time, the pushing member 2143 (optional spring) is compressed, at this time, if the distance between the pushing blocks 2142 is larger than the volume of the agricultural product, the agricultural product will fall into the container 24, if the distance between the pushing blocks 2142 is smaller than the volume of the agricultural product, because the continuously moving pushing block 216 will push the deflecting block 217 and the pushing rubber ring 218 to move together, so that the moving pushing rubber ring 218 will apply a lateral force to the agricultural product to slide along the pushing block 2142 and slide out of the current leaking hole 214.
As shown in fig. 1, 3, 4 and 5, the rotary switching disk 23 includes a driving ring 231 connected to one end of the spindle 22 far from the cover 211, a plurality of pressing strips 232 are connected to a surface of one end of the driving ring 231 near the cover 211, a clamping ring 233 connected to the fixed disk 213 is disposed at one end of the driving ring 231 near the cover 211, a plurality of rotation slots 234 having a right trapezoid structure and used for pushing the pressing strips 232 to move toward one side far from the clamping ring 233 are disposed at one end of the clamping ring 233 near the driving ring 231, an embedding ring slot 235 for clamping the driving ring 231 is disposed on an inner side wall of the fixed storage cylinder 1, and a return spring 236 having an end surface connected to the driving ring 231 and used for pushing the driving ring 231 to return is disposed in the embedding ring slot 235.
As shown in fig. 1 and fig. 3, a limit sleeve 221 is disposed on a side wall of the end of the mandrel 22 away from the blocking cover 211, and a lifting ring sleeve 222 connected with the driving ring 231 is sleeved on a side wall of the limit sleeve 221.
In this embodiment, the mandrel 22 directly drives the position-limiting sleeve 221 to move together, and the specific structure of the position-limiting sleeve 221 is as shown in fig. 3, which can drive the lifting ring sleeve 222 and the driving ring 231 to rotate, and meanwhile, when the lifting ring sleeve 222 moves up and down along with the driving ring 231, the lifting ring sleeve 222 also moves up and down along the position-limiting sleeve 221, but does not move relatively.
In this embodiment, the working principle of the rotary switching disk 23 can refer to the working principle of a multi-refill ball-point pen.
In order to achieve the purpose of independently discharging a plurality of agricultural products (although the screening is completed, the phenomenon that a plurality of agricultural products enter the same escape hole 214 still occurs, so that the agricultural products need to be independently distinguished, so that the sampling of the plurality of agricultural products at the same position simultaneously or successively does not occur), the pressing strip 232 can be driven by the mandrel 22 to rotate clockwise, the pressing strip 232 slides along the inner wall of the current rotation groove 234, the pressing strip 232 is pushed to drive the driving ring 231 to move towards the side far away from the clamping ring 233 along the clamping ring groove 235, the movable driving ring 231 presses the reset spring 236, and after the pressing strip 232 moves to be far away from the current rotation groove 234, the reset spring 236 pushes the driving ring 231 to rise, so that the rising driving ring 231 drives the pressing strip 232 to be clamped into the next rotation groove 234.
As shown in fig. 2, the storage device 24 includes a plurality of supporting sleeve columns 241 connected to the side wall of the spindle 22, one end of each supporting sleeve column 241 far away from the spindle 22 is connected to a guiding sleeve 242, one side of each guiding sleeve 242 near the jacket sampler 25 is provided with a carrying sheet 243 for holding the agricultural products, a plurality of guiding columns 244 connected to the guiding sleeves 242 are arranged between the carrying sheets 243 and the guiding sleeves 242, a pulling member 245 is installed in the guiding columns 244, and one end of each pulling member 245 far away from the guiding columns 244 is provided with a dividing strip 246 connected to the carrying sheet 243.
In this embodiment, the diameter of the plurality of guide sleeves 242 should be set in a linear increasing trend in the counterclockwise direction, and the number of the guide sleeves 242 is larger than the number of the escape holes 214, so that it can be avoided that a plurality of agricultural products enter the same guide sleeve 242, and the mandrel 22 rotates in the clockwise direction, so that the agricultural products with large volume gradually enter the guide sleeve 242 with large diameter.
Taking fig. 3 as an example, when a plurality of agricultural products are sifted for storage, if a plurality of same volume (there may be a relatively smaller volume) agricultural products are sifted from the same sifting hole 214 (e.g., the left sifting hole 214 in fig. 3), then if the next agricultural product falls from the sifting hole 214, a guide sleeve 242 and a hood-cylinder sampler 25 are conveniently located under the sifting hole 214 to hold the agricultural product, then rotating the wheel changing plate 23 will move the current guide sleeve 242 and hood-cylinder sampler 25 away from the sifting hole 214 (clockwise to just below the next sifting hole 214), then the sifting hole 214 will continue to hold the agricultural product, and the next guide sleeve 242 and hood-cylinder sampler 25 (counterclockwise) will continue to hold the product.
When the agricultural products are screened out from the leakage hole 214, if the agricultural products are not screened out from the leakage hole 214 but screened out from the next leakage hole 214 (that is, the agricultural products with large volume are screened out from the next leakage hole 214, and the next leakage hole is calculated clockwise), the current guide sleeve 242 and the cover cylinder sampler 25 corresponding to the leakage hole 214 will be left, and at this time, the current guide sleeve 242 and the cover cylinder sampler 25 will be driven by the rotating wheel changing disc 23 to move to the position right below the next leakage hole 214 and support the agricultural products with large volume, and the operation is cycled in this way, so that the phenomenon that a plurality of agricultural products enter the same guide sleeve 242 can be avoided.
When the agricultural product falls from the leakage hole 214, the agricultural product directly falls into the guide sleeve 242 and slides down along the guide column 244 until the agricultural product is supported by the bearing sheet 243, and at the moment, the positioning strip 246 can limit and fix the agricultural product in a partitioning manner, so that the agricultural product is sampled by aiming at the side wall of the agricultural product during subsequent sampling.
