An agricultural weeding method comprises the following specific steps:
s1, driving equipment into a field to be weeded;
s2, starting equipment;
s3, sucking the head of the weed into the equipment by the suction force of the suction pump;
s4, shoveling out the roots of the weeds by using a soil turning mechanism;

and S6, finally, separating the weeds from the grass clamping mechanism at the tail end of the device through a blanking mechanism, and storing the weeds.
The working principle is as follows: before working, the equipment is opened into a field to be weeded (as shown in figure 1, wheels for moving the equipment are arranged on the supporting mechanism, and the distance from the ground of the equipment can be controlled by adjusting the distance from the wheels to the shell), and then the height from the ground of the equipment is adjusted according to the growth height of weeds in the field, and meanwhile, the telescopic column is adjusted to adjust the height of the soil turning mechanism downwards, so that when the soil turning mechanism moves forwards along with the equipment, the field can be ploughed;
then starting the equipment, taking the left end in the figure 1 as a head, and moving the equipment forward along the field for weeding;
in the weeding process, the air suction pump continuously sucks air (as shown in figure 2), so that the grass inlet holds a suction state to the outside, and weeds at the grass inlet are sucked into the grass inlet;
the conveyor belt keeps rotating clockwise and drives the grass clamping mechanism on the conveyor belt to slide along the boss, when the grass clamping mechanism does not perform grass clamping work, the grass clamping mechanism is positioned at a low section, the clamping hand is tightly attached to the outer side of the conveyor belt, and when the grass clamping mechanism is positioned at a high section, the clamping hand has a certain distance to the outer side of the conveyor belt; (as shown in fig. 11), when the grass clamping mechanism runs from the first high position b to the first low position a (beside the grass inlet), namely a process that the clamping hand is tightly attached to the conveyor belt, in the process, if weeds exist at the clamping hand, the weeds are pressed on the conveyor belt by the clamping hand in the process that the clamping hand is tightly attached to the conveyor belt, and due to the existence of the weeds, the clamping hand can be propped up by the weeds relative to the conveyor belt for a certain height, at the moment, the clamping hand is in a state (as shown in fig. 8) of the grass clamping mechanism, the clamping hand is propped up by the weeds, and then the clamping hand drives the sliding rod to slide towards the outer side of the conveyor belt (at the moment, the spring two is compressed, and a force towards the inside of the conveyor belt is always applied to the sliding rod, so that the clamping hand forms extrusion force on the weeds, and the weeds are stably clamped on the conveyor belt), further, the trigger rod moves left under the driving of the sliding rod (as shown in fig. 6), and then the trigger rod drives the trigger block to move left, so that the sliding rod drives the sliding rod to move left, and further drives the sliding rod to move along the sliding groove and the sliding resistance head to move along the sliding groove and the sliding groove (when the sliding rod, the sliding resistance head and the sliding resistance head of the sliding groove) move left);
after the contact head slides leftwards along the resistor (referring to fig. 10, when the resistance values on the two sides of the contact head are different, correspondingly, the voltage values of the two interfaces of the braking mechanism of the transmission shaft are changed, so as to control the extension and contraction of the transmission shaft), the telescopic rod contracts, so that the conveyor belt is driven to move rightwards and downwards, the contact head is driven to move rightwards and downwards, and when the contact head returns to the middle position of the resistor again, the telescopic rod stops moving; furthermore, the grass inlet is enlarged, so that the position of the grass inlet can be changed according to the amount of weeds, and the suction intensity at the grass inlet is ensured;
meanwhile, a plowing cone of the soil turning mechanism breaks the bottom surface to dig out the roots of the weeds;
then, the dug weeds are conveyed to the rear of the equipment along with the grass clamping mechanism, are loosened by the grass clamping mechanism at the ascending section and are stored in the equipment through the blanking mechanism;
when the grass clamping mechanism passes through the filter plate, the brush in the grass clamping mechanism can clean the filter plate for one time so as to ensure that the filter plate is not blocked; meanwhile, the conveyor belt changes the position along with the weed quantity, so that when the grass clamping mechanism passes through the filter plate, the brush can contact the filter plate and clean the filter plate at one time.
Compared with the prior art, the invention has the beneficial effects that:
1. according to the invention, the weeds to be eradicated are sucked into the equipment in advance in a suction manner, and then the procedures of root removal, transportation and collection are carried out, compared with the traditional scheme, the problems of grass seed falling and secondary growth in the mechanical weeding process can be effectively avoided, the interval and the number of weeds which recur again after each weeding are greatly reduced, so that the weed source which grows again in the field is changed from the grass seeds from which old grass falls and the external grass seeds into the external grass seeds after each weeding, the weed number is effectively reduced from the source, and the fertility loss of the field is reduced to a certain extent, thereby the yield of agricultural products is improved, and the workload of operators is reduced.
2. According to the tong when centre gripping weeds, the height that is propped up by weeds is equipment unit interval weeding volume, removes to prop up the slide bar, and then triggers the piece through the triggering lever pulling, and is further, drives the contact and slides along resistance to this drive telescopic link promotes the conveyer belt, and then changes the size of advancing the grass mouthful, can not cross lowly with the suction strength who guarantees to advance grass mouthful department, and then makes equipment during operation, inhales the grass seed that can be stable all the time, prevents that the grass seed from dropping.
3. Through the inclined design of the brush, the resistor, the sliding groove I and the sliding groove II, firstly, when the grass clamping mechanism passes through the suction pump in the operation process of the equipment, the brush can clean the filter plate for one time, so that the filter plate is prevented from being blocked, and the function of preventing seeds of the equipment from falling to the ground is prevented from being influenced; secondly, through the inclined design of the resistor, the sliding groove I and the sliding groove II, the brush can be kept at a height capable of contacting the filter plate, so that weed seeds cannot fall to the ground in the weeding process, and the duration of weeding is shortened.
