A material lifting device: as shown in fig. 2, the endless lifter 4 is composed of a guide roller 29, a chain 27, and a pallet 28. The guide rollers 29 and the pallets 28 are alternately connected to the chain 27, and the front and rear guide rollers 29 and the pallet 28 in the middle form a guide lifting chute 23. The guide roller drive 3 is arranged on the upper side of the path of the endless lifting device 4, and the guide rollers 29 roll in the guide roller drive 3 under the influence of friction. The separation guide plate 22 is connected to the guide roller driving device 3 and located above the guide roller 29, when the annular lifting mechanism 4 carries walnuts 24 to lift, and when the walnuts 24 pass through the separation guide plate 22, redundant walnuts 24 in the guide lifting groove 23 are removed, and the remaining walnuts 24 are guided to one side of the annular lifting mechanism 4. When the annular lifting mechanism 4 lifts the walnut 24 to the shell breaking rotor 6, the guiding lifting groove 23 and the shell breaking station 20 are overlapped at the picking point 25, so that the shell breaking unit 32 can clamp the walnut.
The shell breaking device comprises: as shown in fig. 2 and 3, the crust breaking rotor 6 is composed of a bearing 11 mounted on the main shaft 10, a shaft end sprocket 12, a supporting plate 30, a main sprocket 18, and a plurality of sets of crust breaking units 32 uniformly arranged around the main shaft 10 and connected to the supporting plate 30. Each group of shell breaking units 32 corresponds to one shell breaking station 20, is divided into a clamping side 33 and a striking side 34, and is arranged on the same axis, and a shell breaking cavity is formed in the middle gap.
The shaft end chain wheel 12 drives the main shaft 10, the supporting disc 30 on the shaft, the main chain wheel 18 and the shell breaking unit 32 to rotate together. The main chain wheel 18 in the shell breaking rotor 6 drives the annular lifting mechanism 4, and the circumferential angle positions of the main chain wheel 18 and the main shaft 10 are adjustable, so that each guide lifting groove 23 and the shell breaking station 20 synchronously reach a picking point 25.
The shell breaking control device comprises: as shown in fig. 1 and 3, the clamping motion control device 5, the locking motion control device 8 and the striking motion control device 9 are all connected to the frame 1, are arranged coaxially with the crust breaking rotor 6, and are respectively matched with the clamping side 33, the locking block 19 and the striking side 34, and the corresponding motion generation and withdrawal timings are controlled by adjusting the clamping motion control device 5, the locking motion control device 8 and the striking motion control device 9.
The shell breaking process is as follows: when the speed reducing motor 15 rotates, the chain wheel 14 connected with the output shaft rotates, the chain 13 drives the chain wheel 12, the chain wheel 12 rotates, the main chain wheel 18 is driven by the main shaft 10, and the annular lifting mechanism 4 drives the tensioning chain wheel 16. When the annular lifting mechanism 4 operates, the walnuts 24 in the hopper 2 naturally fall into the guide lifting groove 23 between two adjacent guide rollers 29 from the rectangular notch, and the guide rollers 29 roll under the action of the guide roller driving device 3, so that the walnuts 24 roll and rotate in opposite directions under the action of friction force of the rotating rollers, the long axis direction of the walnuts is parallel to the axis direction of the guide rollers 29, a consistent lying posture is formed, and preparation is made for breaking shells. The walnuts 24 brought out from the hopper 2 through the annular lifting mechanism 4 move towards the shell breaking rotor 6, and when passing through the separation guide plate 22, redundant walnuts 24 can be removed, so that only one walnut in the guide lifting groove 23 is ensured, and the walnut is guided to one side of the annular lifting mechanism 4. When the distance between the guide material lifting grooves 23 is moved, the shell breaking rotor 6 just rotates over one shell breaking station 20, so that each walnut 24 accurately corresponds to one shell breaking station 20. That is, each time the walnut 24 passes through the shell breaking station 20, the long axis of the walnut coincides with the axis of the shell breaking unit 32, and the clamping, taking out, locking and striking actions are waited for.
Meanwhile, the clamping action control device 5 controls the clamping side action of the shell breaking unit 32 to push the walnuts 24 in the guide lifting groove 23 to the conical end surface of the beating side, so that the walnuts 24 are clamped. The guide lifting groove 23 is then separated from the shell breaking station 20, and the shell breaking unit 32 takes the walnuts 24 out of the guide lifting groove 23. With the continuous rotation of the shell breaking rotor 6, the locking action control device 8 controls the locking block 19 to act and enter a locking state, and the locking state lasts for a certain time. During the period, as the shell breaking rotor 6 continues to rotate, the beating action control device 9 controls the beating side action, the walnut shells are broken under the action of impact, and the walnut kernels are not impacted while the walnut shells are broken through the preset beating amount. The crust breaking rotor 6 continues to rotate, and the beating side is controlled by the beating action control device 9 to return to the original position. Subsequently, the locking operation control means 8 releases the locking piece 19, and the locking state is ended, and at the same time, the gripping operation control means 5 controls the gripping side operation to return to the original position. The crushed walnuts between the gripping side and the beating side are released and fall into the discharge hopper 21, so that the whole action of the group of shell breaking units 32 is completed and the walnut shell breaking unit is ready for next shell breaking. In the continuous rotation process, each group of shell breaking units 32 completes the actions of clamping, taking out, locking, striking, releasing and returning in turn under the coordination of the shell breaking control device, and the actions are carried out in a circulating manner. If the processing efficiency needs to be improved, the volume of the material box 2 can be increased, and the rotating speed of the shell breaking rotor 6 is increased.
The chain 27 is a single-row double-lug chain, and the guide rollers 29 are made of nylon material.
Above technical characteristics constitute the utility model discloses a best embodiment, it has stronger adaptability and best implementation effect, can increase and decrease unnecessary technical characteristics according to actual need, satisfies the needs of different situation.
