Abstract

This invention discloses a green walnut collecting device, belonging to the field of agricultural production tools. It includes a collecting box and a guide plate and partition plate fixedly connected to the inner wall of the collecting box. A rubber tube is fixedly connected to the bottom surface of the guide plate and runs through the interior of a cylindrical tube. A set of rinsing needles is fixedly connected to the inner wall of the rubber tube. In this invention, a first motor drives a reciprocating screw to rotate, causing a nut threaded to the outer surface of the reciprocating screw to move an annular plate, a pressing block, and a pressure rod up and down. This causes the rinsing needles on the inner wall of the rubber tube to press the outer skin of the flowing green walnuts, achieving a certain rinsing effect. Simultaneously, a second motor drives an eccentric wheel to rotate, further pressing and rinsing the flowing green walnuts. The downward-moving pressure rod allows external air to flow into the collecting box, increasing air circulation inside the device and facilitating the evaporation of moisture from the green walnut skin. The device provides pretreatment for the green walnuts, which is beneficial for subsequent rinsing.

Description

Technical Field

[0001] This invention belongs to the field of agricultural production tools technology, and in particular relates to a green walnut picking and collecting device. Background Technology

[0002] Green-skinned walnuts are the immature fruits of plants belonging to the genus Juglandaceae in the family Juglandaceae. They are covered with a greenish-yellow husk and contain edible kernels. They have edible, medicinal, and economic value. Green-skinned walnuts are highly adaptable and easy to cultivate and manage, making them a specialty economic crop in many regions.

[0003] The outer skin of a green walnut is a layer of greenish-yellow husk that covers the hard shell of the walnut and serves a protective function. The green husk is bitter and rough, and eating it directly will affect the aroma and crisp texture of the kernel. After peeling, the natural flavor of the kernel can be brought out. After the green walnut is harvested, the moisture in the outer skin gradually evaporates, which loosens the connection between the green husk and the hard shell, forming a natural abscission layer, making it easier to peel off the outer skin. Therefore, in order to peel it better, the collected green walnuts often need to be placed in a ventilated place for several days before processing. However, the existing green walnut collection and harvesting equipment lacks pretreatment of the green walnuts, which is not conducive to the subsequent peeling of the green walnuts. Summary of the Invention

[0008] As a further description of the above technical solution: The end of the pressure rod away from the nut is fixedly connected to a slider, which is slidably connected to a groove opened in the inner wall of the collection box. The rubber block set directly above the abutment is fixedly connected to the outer surface of the pressure rod.

[0009] As a further description of the above technical solution: The upper end of the telescopic spring is fixedly connected to the bottom surface of the annular piston plate. A set of through holes are opened on the outer surface of the collection box, and the filter screen snapped onto the outer surface of the collection box is in contact with the air inlet end and the through holes of the second one-way valve.

[0010] As a further description of the above technical solution: A base plate is fixedly connected to the lower part of the inner wall of the collection box. A heating wire is installed inside the annular protective mesh fixedly connected to the bottom surface of the base plate. The air inlet of the first one-way valve is connected to the air outlet of the second one-way valve, and the air outlet of the first one-way valve is connected to the inside of the collection box through the base plate, the annular protective mesh and the heating wire.

External air flows into the collection box, increasing the air circulation inside the device and facilitating the evaporation of moisture from the green walnut skin. The device has a pre-treatment function for green walnuts, which is beneficial for the subsequent peeling of the green walnuts. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-7 This invention provides a technical solution: a green walnut picking and collecting device, including a collecting box 1 and a guide plate 2 and a partition plate 3 fixedly connected to the inner wall of the collecting box 1. A cover plate 35 is snapped onto the lower part of the front of the collecting box 1. The cover plate 35 facilitates the discharge of green walnuts inside the collecting box 1. The mesh plate 36 embedded on the outer surface of the cover plate 35 is connected to the interior of the collecting box 1. The mesh plate 36 facilitates the air circulation inside the collecting box 1. A set of universal wheels 37 is fixedly connected to the bottom surface of the collecting box 1. The universal wheels 37 facilitate the movement of the device. A rubber tube 5 is fixedly connected to the bottom surface of the guide plate 2 and is disposed inside the cylinder 4. The bottom surface of the cylinder 4 is fixedly connected to the partition plate 3. A set of piercing needles 6 is fixedly connected to the inner wall of the rubber tube 5. A reciprocating screw 8 is fixedly connected to the output end of the first motor 7 fixedly connected to the bottom surface of the partition plate 3. The first motor 7 does not contact the penetration point of the partition plate 3. An annular plate 10 is fixedly connected to the outer surface of the nut 9 threaded on the outer surface of the reciprocating screw 8.

[0019] A straight rod 32 is fixedly connected to the upper surface of the partition 3. The upper end of the straight rod 32 is fixedly connected to the bottom surface of the guide plate 2. The upper end of the reciprocating screw 8 is rotatably connected to the bottom surface of the guide plate 2. A limiting ring 33 slidably connected to the outer surface of the straight rod 32 is fixedly connected to the outer surface of the annular plate 10. The cooperation between the straight rod 32 and the limiting ring 33 makes the reciprocating movement of the annular plate 10 more stable. A pressure rod 20 is fixedly connected to the outer surface of the nut 9. A slider 24 is fixedly connected to the end of the pressure rod 20 away from the nut 9. The slider 24 is slidably connected to the groove 25 opened in the inner wall of the collection box 1. The cooperation between the slider 24 and the groove 25 makes the outer surface of the pressure rod 20 more stable. The structure is more stable. The rubber block 26 located directly above the abutment rod 19 is fixedly connected to the outer surface of the pressure rod 20, so that when the nut 9 drives the pressure rod 20 to move up and down, it can contact the abutment rod 19. The extrusion block 11 fixedly connected to the inner wall of the annular plate 10 passes through the cylinder 4 and is slidably connected to the rubber tube 5. The outer surface of the cylinder 4 is provided with a through groove 21. The extrusion block 11 is slidably connected to the inner wall of the through groove 21. The through groove 21 limits the up and down movement of the extrusion block 11. The first ball 22 rotatably connected to the outer surface of the extrusion block 11 contacts the outer surface of the rubber tube 5. The first ball 22 reduces the friction between the extrusion block 11 and the outer surface of the rubber tube 5.

[0020] The output end of the second motor 12, which is fixedly connected to the bottom surface of the partition 3, passes through the partition 3 and is fixedly connected to an eccentric wheel 13. The eccentric wheel 13 passes through the cylinder 4 and is slidably connected to the rubber tube 5. The upper end of the second motor 12 is rotatably connected to the bottom surface of the guide plate 2. The eccentric wheel 13 is slidably connected to the penetration point of the cylinder 4 to prevent friction between the eccentric wheel 13 and the penetration point of the cylinder 4. A set of second ball bearings 23 is rotatably connected to the outer surface of the eccentric wheel 13. The second ball bearings 23 are in contact with the outer surface of the rubber tube 5. The setting of the second ball bearings 23 reduces the frictional force between the eccentric wheel 13 and the rubber tube 5. An annular piston plate 15 is slidably connected to the inner wall of the annular piston cylinder 14, which is fixedly connected to the bottom surface of the annular piston cylinder 14. A set of telescopic springs 16 is fixedly connected to the inner bottom wall of the annular piston cylinder 14. The upper end of the telescopic springs 16 is fixedly connected to the bottom surface of the annular piston plate 15. Figure 1 and Figure 7 All the telescopic springs 16 are in their natural state, providing a reset effect for the annular piston plate 15. A set of first one-way valves 17 embedded in the bottom wall of the annular piston cylinder 14 are connected to the inside of the collection box 1. The outlet of each first one-way valve 17 is equipped with a vent pipe 38, which facilitates the outlet of the first one-way valve 17 to the lower part of the bottom plate 29 while preventing the heat generated by the heating wire 31 from diffusing to the upper part of the bottom plate 29. A set of second one-way valves 18 embedded on the outer surface of the collection box 1 are connected to the annular piston cylinder 14. The internal parts are connected. A set of through holes 27 are opened on the outer surface of the collection box 1. The opening of the through holes 27 provides favorable conditions for heat dissipation inside the collection box 1. The filter screen 28 that is snapped onto the outer surface of the collection box 1 is in contact with the air inlet end of the second one-way valve 18 and the through holes 27. A set of abutment rods 19 fixedly connected to the upper surface of the annular piston plate 15 extends to the upper part of the partition plate 3. The abutment rods 19 are slidably connected to the through-hole of the annular piston cylinder 14 and the partition plate 3 to prevent friction between the abutment rods 19 and the through-hole of the annular piston cylinder 14 and the partition plate 3.

[0021] A base plate 29 is fixedly connected to the lower part of the inner wall of the collection box 1. A straight cylinder 34 fixedly connected to the bottom surface of the partition 3 is connected to the lower end of the rubber tube 5. The lower end of the straight cylinder 34 extends to the lower part of the base plate 29. The straight cylinder 34 facilitates the falling of the green-skinned walnuts after cracking. A heating wire 31 is installed inside the annular protective net 30 fixedly connected to the bottom surface of the base plate 29. The air inlet of the first one-way valve 17 is connected to the air outlet of the second one-way valve 18. The air outlet of the first one-way valve 17 is connected to the interior of the collection box 1 through the base plate 29, the annular protective net 30, and the heating wire 31. The heating wire 31, Heating wire, also known as electric heating wire, is a metal resistance wire that converts electrical energy into heat energy using the heating effect of electric current. It is widely used in industrial heating equipment and household heating appliances in metallurgy, machinery, medical, chemical, ceramic, electronic, electrical, and glass industries. Heating wire 31 works through the heating effect of electric current. When current passes through the metal resistance wire, electrical energy is converted into heat energy, causing the resistance wire to heat up. The setting of heating wire 31 heats the air flowing into the lower part of the bottom plate 29, which is conducive to the evaporation of moisture from the outer skin of green walnuts inside the device. The device has a pre-treatment function for green walnuts, which is more conducive to the subsequent peeling of green walnuts.

[0022] The collected green walnuts are placed on the upper part of the guide plate 2. Under the action of gravity, the green walnuts move into the interior of the rubber tube 5. The operation of the first motor 7 drives the reciprocating screw 8 to rotate, causing the nut 9 connected to the thread on the outer surface of the reciprocating screw 8 to drive the annular plate 10, the extrusion block 11, and the pressure rod 20 to move up and down reciprocally. This causes the peeling needles 6 on the inner wall of the rubber tube 5 to squeeze the outer skin of the flowing green walnuts to achieve a certain peeling effect. At the same time, the operation of the second motor 12 drives the eccentric wheel 13 to rotate, further causing the peeling needles 6 on the inner wall of the rubber tube 5 to squeeze and peel the flowing green walnuts. After the green walnuts are crushed, they fall into the inner bottom wall of the collection box 1 through the straight cylinder 34. With the cooperation of the telescopic spring 16, the intermittent contact between the downward pressure rod 20 and the abutment rod 19 causes the annular piston plate 15 to move up and down on the inner wall of the annular piston cylinder 14. External air flows into the collection box 1 through the filter screen 28, the second one-way valve 18, the annular piston cylinder 14, the first one-way valve 17 and the heating wire 31, which increases the air circulation inside the device and is conducive to the evaporation of moisture from the green walnut skin. The device has a pre-treatment function for green walnuts, which is beneficial for the subsequent peeling of green walnuts.

[0023] Working principle: In use, the first motor 7, the second motor 12, and the heating wire 31 are connected to a mobile power source. The picked-up green walnuts are placed on the upper part of the guide plate 2. Under the action of gravity, the green walnuts move into the interior of the rubber tube 5. The operation of the first motor 7 drives the reciprocating screw 8 to rotate, causing the nut 9 connected to the thread on the outer surface of the reciprocating screw 8 to drive the annular plate 10, the extrusion block 11, and the pressure rod 20 to move up and down reciprocally. This causes the peeling needles 6 on the inner wall of the rubber tube 5 to extrude the outer skin of the flowing green walnuts to achieve a certain peeling effect. At the same time, the operation of the second motor 12 drives the eccentric wheel 13. The rotation further causes the inner wall of the rubber tube 5 to squeeze and break the skin of the flowing green walnuts with the inner wall of the inner wall of the inner wall of the collection box 1 through the straight cylinder 34. With the cooperation of the telescopic spring 16, the intermittent contact between the downward pressure rod 20 and the abutment rod 19 causes the annular piston plate 15 to move up and down on the inner wall of the annular piston cylinder 14. External air flows into the collection box 1, which increases the air circulation inside the device and is conducive to the evaporation of moisture from the outer skin of the green walnuts. The device has the function of pre-treatment of green walnuts, which is beneficial to the subsequent peeling of green walnuts.
