Description

Technical Field

[0001] This invention relates to the field of walnut peeling technology, and more particularly to a processing device for walnut peeling. Background Technology

[0002] Walnuts are a widely cultivated economic crop in my country. Peeling the green husk or outer shell is a key step in the processing. Walnuts are harvested in a concentrated period, and the peeling process needs to be completed in a short time, otherwise the quality of the kernels will be affected. Traditional manual peeling methods are labor-intensive and extremely inefficient, and cannot meet the needs of large-scale production.

[0003] The reference document is Chinese invention patent "A Walnut Green Peeling Machine" patent number: ZL201710694811.X. This patent discloses a highly efficient and environmentally friendly walnut green peeling device that achieves green peeling through mechanical structure, saving labor costs and liberating productivity. Its core technology uses a single power to drive the peeling component to operate, and uses the principle of squeezing and kneading to achieve the separation of green peel from walnut.

[0004] The aforementioned comparative document uses a single-power drive mode, which results in uneven distribution of walnuts in the peeling area, with some material easily accumulating, leading to incomplete peeling and limited processing efficiency. Furthermore, the contact method between the material and the peeling components is relatively simple, lacking flexible pushing and uniform force design, which easily causes damage to the kernels. At the same time, the connection between the material conveying and collection links after peeling is not tight enough, requiring additional manual intervention to assist in transferring the material, making it difficult to adapt to the needs of continuous and large-scale processing, and seriously restricting the overall operating efficiency of the equipment. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention provides a processing device for peeling walnuts, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A processing device for peeling walnuts includes a crushing tank, a collecting component, a discharging component, a conveying component, and a peeling component. The peeling component includes a rotating disc movably installed inside the crushing tank. A housing is fixedly installed on the top of the rotating disc. A first rotating shaft is movably installed inside the rotating disc, and a drive wheel is fixedly installed on the top of the first rotating shaft. A second rotating shaft is movably installed inside the rotating disc. Spiral blades are fixedly installed on the outer surfaces of both the second and first rotating shafts. A transmission belt drives the drive wheel and the driven wheel. A peeling roller is fixedly installed inside the crushing tank. A second motor is fixedly installed on the top of the housing, and the output end of the second motor is fixedly connected to the drive wheel. The peeling component is used to peel the green husks of walnuts. The discharging component is used to slowly feed the peeled walnuts and walnuts into the conveying component. The conveying component is used to transport the walnuts to the collecting component and slowly discharge the walnut husks through a debris discharge hole. The collecting component is used to collect the peeled walnuts.

[0007] Furthermore, the discharge assembly includes a guide plate fixedly installed inside the crushing tank, a vertical plate fixedly installed inside the crushing tank, a baffle movably installed at the bottom of the guide plate, a hinge block fixedly installed at the bottom of the baffle, and a cylinder fixedly installed between the vertical plate and the hinge block, with the vertical plate and the cylinder forming a 30-degree angle.

[0008] Furthermore, the conveying assembly includes a conveying pipe fixedly installed inside the crushing tank. A third motor is fixedly installed on the left side of the conveying pipe, and a drive gear is fixedly installed at the output end of the third motor. One end of the drive gear is movably installed inside the conveying pipe. A spiral blade is movably installed inside the conveying pipe. A driven gear is fixedly installed at one end of the spiral blade, and the driven gear and the drive gear are meshed. The bottom of the conveying pipe has a debris-collecting hole, and the debris-collecting hole is arranged in a linear array.

[0009] Furthermore, the collection assembly includes a limiting plate fixedly installed at the bottom of the conveying pipe, a fixing rod movably installed inside the limiting plate, a rotating block hinged to the right end of the fixing rod, a collection box fixedly installed on the left side of the fixing rod, a push rod fixedly installed on the left side of the collection box, and the outer surface of the push rod is L-shaped, and an inclined plate fixedly installed at the top of the conveying pipe.

[0010] Furthermore, a support is fixedly installed on the right side of the conveying pipe, and the inside of the support is U-shaped.

[0011] Furthermore, a support frame is fixedly installed on the top of the crushing tank, a first motor is fixedly installed on the top of the support frame, and the output end of the first motor is fixedly connected to the housing. An inlet is fixedly installed on the outer surface of the crushing tank.

[0012] Furthermore, the bottom of the conveying pipe is provided with debris-collecting holes, and the debris-collecting holes are arranged in a linear array.

[0013] Furthermore, the bottom of the collection box is fixedly equipped with columns around its perimeter, and the bottom of the columns is hinged with casters. The left side of the conveying pipe is fixedly provided with a discharge port.

[0014] Compared with existing technologies, the advantages of this invention are: 1. The equipment can be conveniently fed through the inlet and adopts a dual-power design. The first motor drives the rotating disc to revolve so that the walnuts are evenly dispersed. The second motor drives the first rotating shaft, the second rotating shaft and the spiral blade to rotate, pushing the walnuts to be fully rubbed and squeezed with the peeling roller. The peeling is efficient and thorough and does not damage the kernels. The mixture is sent to the collection component through the conveying pipe. The process is continuous, with little manual intervention, suitable for large-scale processing and stable operation.

[0015] 2: The guide plate fixed inside the crushing tank stably receives the walnuts after the initial processing, avoiding messy accumulation; the cylinder at a 30-degree angle to the vertical plate, through the structure of the hinge block at the bottom of the vertical plate and the baffle, drives the baffle to open and close flexibly by telescopic movement, so that the feeding speed matches the processing capacity of the peeling area, ensuring that the walnuts are fed evenly, preventing equipment blockage and avoiding waste of efficiency, laying a solid foundation for stable peeling.

[0016] 4: The drive gear is driven by the third motor on the left side of the conveying pipe inside the crushing tank. The meshing of the teeth drives the driven gear to rotate the spiral blades, which stably pushes the peeled mixture.

[0017] 5: The linear array of impurity dropping holes at the bottom of the conveying pipe can efficiently separate skin and slag impurities without the need for additional impurity removal processes, shortening the processing flow. The continuous pushing of the spiral blades, combined with the precise screening of the impurity dropping holes, ensures continuous conveying, improves the impurity separation effect, reduces subsequent processing costs, and adapts to the needs of large-scale processing.

[0018] 6: The L-shaped push rod on the left side of the collection box is connected to the universal wheel at the bottom column, which can be easily and accurately moved to the bottom of the discharge port on the left side of the conveying pipe. It is highly flexible in movement and easy to align. The movable fixing rod in the bottom limiting plate of the conveying pipe fits against the box and the rotating block locks it, which can quickly and firmly fix the collection box and prevent displacement and leakage during operation.

[0021] Example 1 Reference Figure 6 A processing device for peeling walnuts includes a crushing tank 1, a collecting component, a discharging component, a conveying component, and a peeling component. The peeling component includes a rotating disk 2 movably installed inside the crushing tank 1. A housing 5 is fixedly installed on the top of the rotating disk 2, and a first rotating shaft 25 is movably installed inside the rotating disk 2.

[0022] The peeling component is used to peel the green husk of walnuts. The feeding component is used to slowly feed the peeled walnut husks and walnuts into the conveying component. The conveying component is used to transport the walnuts to the collecting component and slowly discharge the walnut husks through the debris discharge hole. The collecting component is used to collect the peeled walnuts.

[0023] A drive wheel 27 is fixedly installed on the top of the first rotating shaft 25. A second rotating shaft 26 is movably installed inside the rotating disk 2. Spiral blades 35 are fixedly installed on the outer surfaces of both the second rotating shaft 26 and the first rotating shaft 25. A transmission belt 29 is connected between the drive wheel 27 and the driven wheel 28. A peeling roller 30 is fixedly installed inside the crushing tank 1.

[0024] The walnuts are pushed by the self-rotating mechanism and thoroughly rubbed and squeezed by the fixed peeling roller 30, which greatly improves the peeling efficiency and thoroughness, and is less likely to damage the kernels. After peeling, the mixture is directly transported to the collection component through the conveying pipe 8, realizing a continuous process of peeling, conveying and collecting, reducing manual intervention, adapting to the needs of large-scale processing, with a reasonable overall structural design and strong operational stability.

[0025] A second motor 7 is fixedly installed on the top of the housing 5, and the output end of the second motor 7 is fixedly connected to the drive wheel 27.

[0026] A support frame 4 is fixedly installed on the top of the crushing tank 1, and a first motor 6 is fixedly installed on the top of the support frame 4. The output end of the first motor 6 is fixedly connected to the housing 5. An inlet 3 is fixedly installed on the outer surface of the crushing tank 1.

[0027] Walnuts to be peeled can be conveniently fed into the crushing tank 1 through the feed port 3. The feeding operation is simple and efficient. With the help of the dual power design of the first motor 6 driving the rotating disk 2 to revolve and the second motor 7 driving the first rotating shaft 25 and the second rotating shaft 26 to rotate synchronously, the spiral blade 35 generates centrifugal force as it revolves with the rotating disk 2, so that the walnuts are evenly dispersed.

[0028] The motor model is Y80M1-2, and its working principle is based on the principle of electromagnetic induction to convert electrical energy into mechanical energy: after the power is turned on, the stator winding generates an alternating magnetic field, and the rotor cuts the magnetic field lines under the action of the magnetic field force to form electromagnetic torque, which drives the rotor to rotate; by adjusting the current direction and frequency through the commutator or frequency converter, the speed and torque can be precisely controlled to provide power output for equipment such as water pumps.

[0029] A support base 10 is fixedly installed on the right side of the conveying pipe 8, and the interior of the support base 10 is U-shaped.

[0030] Because the support base 10 has a U-shaped interior on the right side of the conveying pipe 8, it provides stable support for the third motor 9, ensuring the stability of the third motor 9 during use, reducing the shaking of the third motor 9 during use, and extending the service life of the third motor 9.

[0031] In this embodiment, the walnuts to be peeled are first fed into the crushing tank 1 through the feed port 3 on the outer surface of the crushing tank 1. Then the equipment is started to make each component run: the first motor 6 installed on the support frame 4 on the top of the crushing tank 1 works, and its output end drives the box 5 on the top of the rotating disk 2 to rotate, thereby driving the rotating disk 2 installed in the crushing tank 1 to rotate. At the same time, the second motor 7 at the top of the housing 5 starts, driving the drive wheel 27 at the top of the first rotating shaft 25 to rotate. The drive wheel 27 drives the driven wheel 28 on the second rotating shaft 26 through the transmission belt 29, so that the first rotating shaft 25 and the second rotating shaft 26 rotate synchronously, and the spiral blades 35 on the outer surface of both rotate accordingly. Walnuts are dispersed under the centrifugal force of the rotating disc 2 driving the spiral blades 35 to revolve. They are then rubbed and squeezed by the rotating spiral blades 35 and the peeling rollers 30 fixed in the crushing tank 1 to complete the peeling. The mixture is then transported to the collection component through the conveying pipe 8 to complete the material separation and collection.

[0032] Example 2 Reference Figures 1-3 A processing device for peeling walnuts includes a feeding assembly comprising a guide plate 34 fixedly installed inside a crushing tank 1, a vertical plate 21 fixedly installed inside the crushing tank 1, and a baffle 22 movably installed at the bottom of the guide plate 34, which is used to slowly discharge peeled walnuts into the conveying assembly to facilitate the conveying efficiency of walnuts.

[0033] A hinge block 23 is fixedly installed at the bottom of the baffle 22, and a cylinder 24 is fixedly installed between the vertical plate 21 and the hinge block 23, with the vertical plate 21 and the cylinder 24 forming a 30-degree angle.

[0034] The cylinder is of the SC series. When the start-up is initiated, compressed air enters the internal chamber of the cylinder through the air inlet, pushing the piston to move linearly along the inner wall of the cylinder. The piston drives the piston rod to extend, thus performing external work such as moving mechanical parts or clamping workpieces. When the control system switches the air path, the compressed air in the cylinder is discharged through the exhaust port. Under the action of the return spring or reverse compressed air, the piston and piston rod return to the initial position, completing one cycle.

[0035] The conveying assembly includes a conveying pipe 8 fixedly installed inside the crushing tank 1. A third motor 9 is fixedly installed on the left side of the conveying pipe 8, and a drive gear 20 is fixedly installed at the output end of the third motor 9. One end of the drive gear 20 is movably installed inside the conveying pipe 8. A spiral blade 17 is movably installed inside the conveying pipe 8. A driven gear 19 is fixedly installed at one end of the spiral blade 17, and the driven gear 19 and the drive gear 20 are meshed.

[0036] The bottom of the conveying pipe 8 is provided with debris discharge holes 18, and the debris discharge holes 18 are arranged in a linear array.

[0037] The walnuts are discharged in a timely manner by means of a linear array of 18 holes inside the conveying pipe 8.

[0038] In this embodiment, the pre-processed walnuts are received by the guide plate 34 fixed inside the crushing tank 1. At this time, the cylinder 24, which is installed at a 30-degree angle to the vertical plate 21, is activated. Its two ends are respectively connected to the hinge block 23 at the bottom of the vertical plate 21 and the baffle 22. The cylinder 24 extends and retracts, causing the hinge block 23 to rotate, so that the baffle 22, which is movably installed at the bottom of the guide plate 34, opens and closes, so that the walnuts enter the peeling area at a set speed to complete the peeling. After peeling, the walnuts and the mixture of peel residue enter the conveying assembly: the third motor 9 installed on the left side of the conveying pipe 8 inside the crushing tank 1 starts, and its output end drives the drive gear 20 to rotate. The drive gear 20 drives the driven gear 19 inside the conveying pipe 8 through tooth meshing, which in turn causes the spiral blade 17 inside the conveying pipe 8 to rotate. The spiral blade 17 pushes the mixture along the conveying pipe 8. During the process, impurities such as peel residue are leaked out from the linear array of impurity discharge holes 18 at the bottom of the conveying pipe 8, so that material conveying and preliminary impurity removal are carried out simultaneously.

[0039] Example 3 Reference Figures 4-5 A processing device for peeling walnuts includes a collection assembly comprising a limiting plate 31 fixedly installed at the bottom of a conveying pipe 8, a fixing rod 32 movably installed inside the limiting plate 31, a rotating block 33 hinged to the right end of the fixing rod 32, a collection box 13 fixedly installed on the left side of the fixing rod 32, a push rod 12 fixedly installed on the left side of the collection box 13, and the outer surface of the push rod 12 is L-shaped, and an inclined plate 16 fixedly installed at the top of the conveying pipe 8.

[0040] Guided by the inclined plate 16 at the top of the conveying pipe 8, the walnuts pushed by the spiral blades 17 are guided to slide precisely to the discharge port 11, reducing material spillage and loss. The unloading and transfer can be completed by rotating the rotating block 33 in the opposite direction and releasing the fixing rod 32. The overall operation is simple and efficient, greatly reducing labor intensity, adapting to the needs of continuous production, and improving collection and transfer efficiency.

[0041] The feeding rhythm of walnuts is controlled by the feeding assembly. A guide plate 34 fixed inside the crushing tank 1 stably receives the pre-processed walnuts, preventing haphazard accumulation. A cylinder 24, installed at a 30-degree angle to the vertical plate 21, connects the vertical plate 21 to the bottom hinge block 23 of the baffle 22 at both ends. Its telescopic movement drives the hinge block 23 to rotate, allowing the bottom baffle 22 of the guide plate 34 to open and close flexibly. This design matches the feeding speed to the processing capacity of the peeling area, ensuring that walnuts enter the peeling area evenly. It prevents equipment blockage caused by excessively rapid feeding and avoids inefficiency caused by excessively slow feeding, providing a fundamental guarantee for stable peeling.

[0042] The bottom of the collection box 13 is fixedly mounted with columns 14 around its perimeter. The bottom of the columns 14 is hinged with casters 15. The left side of the conveying pipe 8 is fixedly provided with a discharge port 11.

[0043] The cooperation between the collection box 13 and the column 14 makes it easy to push the collection box 13 with the push rod 12, thus ensuring the efficiency of transferring the walnuts inside the collection box 13.

[0044] In this embodiment, the L-shaped push rod 12 on the left side of the collection box 13 is held, and the universal wheels 15 hinged to the bottom of the fixed columns 14 around the bottom of the collection box 13 are used to push the collection box 13 to move it directly below the discharge port 11 on the left side of the conveying pipe 8; then the fixing rod 32 movably installed in the bottom limiting plate 31 of the conveying pipe 8 is adjusted to fit against the side of the collection box 13, and the rotating block 33 hinged to the right side of the fixing rod 32 is rotated to lock the fixing rod 32, thereby fixing the collection box 13. When the spiral blades 17 of the conveying component push the peeled and screened walnuts into the conveying pipe 8, the walnuts slide down along the inclined plate 16 fixed at the top of the conveying pipe 8 and fall precisely into the collection box 13 through the discharge port 11. After the collection box 13 is full, the rotating block 33 is rotated in the opposite direction to release the fixing rod 32. The collection box 13 is pushed by the push rod 12 and moved to the unloading area by the casters 15, thus completing the walnut collection and transfer operation.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
