Description

Technical Field

[0001] This utility model relates to the field of nut shelling technology, and in particular to a hazelnut peeling machine. Background Technology

[0002] Hazelnuts, one of the world's four major nuts, are rich in unsaturated fatty acids, protein, vitamin E, and minerals, possessing extremely high nutritional and economic value. Currently, hazelnut peeling machines on the market are mainly divided into three categories: single mechanical extrusion type, pressure differential peeling type, and manual-assisted type.

[0003] However, single mechanical extrusion peeling machines are prone to problems such as "hard shells not cracking" or "kernels being crushed," resulting in a low kernel integrity rate. Differential pressure peeling machines suffer from difficulty in precisely controlling pressure, requiring long periods of inflation and resulting in low efficiency. Furthermore, low pressure may lead to incomplete peeling, while high pressure may cause kernels to be thrown away or damaged. At the same time, a large amount of shell debris carried by the airflow will be directly discharged, causing not only dust pollution but also potential blockage of pipes, affecting continuous operation of the equipment. Moreover, there is no effective self-cleaning mechanism, resulting in high maintenance frequency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a hazelnut peeling machine, which aims to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a hazelnut peeling machine, comprising a shell-cracking device and a shell-peeling device, wherein the shell-cracking device comprises a first container, the first container having a first inlet, the first container being rotatably connected to an elastic roller, the elastic roller being fixedly connected to the output end of a motor, the motor housing being fixedly connected to the first container, and a feeding plate being provided at the outlet of the first container.

[0006] The shelling device includes a second container, which has a second inlet and is connected to a feeding plate. The second container has a pressurization pipe and a depressurization pipe. The second container is rotatably connected to a rotating plate. The second container has an arc-shaped protrusion corresponding to the rotating plate inside. The second inlet has a first sealing block and the outlet of the second container has a second sealing block. Both the first and second sealing blocks are equipped with quick-release devices.

[0007] Both the pressurization pipe and the depressurization pipe are fixedly connected to a filter screen and a dust removal device.

[0008] Optionally, the quick-release device includes a hand-tightening part, one end of which is fixedly connected to a spring, and the other end of which is fixedly connected to a connecting frame. The hand-tightening part is fixedly connected to a limiting shaft, and the connecting frame is sleeved with the limiting shaft. Both the first container and the second container are provided with grooves corresponding to the limiting shaft.

[0009] Optionally, the groove includes an arc-shaped groove and a rectangular groove.

[0010] Optionally, the dust removal device includes a rectangular shell, which is fixedly connected to a filter screen. One end of the rectangular shell is fixedly connected to an elastic shaft, and the other end of the elastic shaft is fixedly connected to a moving block. The moving block is slidably connected to the rectangular shell, and a hammer is fixedly connected to the moving block. The moving block has teeth, and the rectangular shell is rotatably connected to a half gear corresponding to the teeth. The half gear is fixedly connected to the output end of a micro motor, and the outer shell of the micro motor is fixedly connected to the rectangular shell.

[0011] Optionally, the ash-removing device is provided in multiple sets.

[0012] The beneficial effects of the above scheme are as follows:

[0013] By combining a shell-cracking device and a peeling device, the cracks created by the shell-cracking device in the hazelnuts can accelerate the internal pressurization speed of the hazelnuts during subsequent peeling, thereby improving peeling efficiency. Furthermore, hazelnuts with cracks are easier to peel during the pressure differential peeling stage. Combining a mechanical peeling machine and a pressure differential peeling machine not only improves the kernel integrity rate but also increases the efficiency of hazelnut peeling.

[0014] By installing a dust-vibrating device, the filter screen in the pipeline is regularly vibrated to prevent it from being in a high-dust environment for a long time, which could cause the filter screen to become clogged and affect the efficiency of the device during pressurization and depressurization.

[0027] Reference Figures 1 to 6 The present invention provides a further description of an embodiment of a hazelnut peeling machine.

[0028] A hazelnut peeling machine includes a shell-cracking device 1 and a shell-peeling device 2. The shell-cracking device 1 includes a first container 3 with a first inlet 4. The first container 3 is rotatably connected to an elastic roller 5, and the output end of a motor 6 is fixedly connected to the elastic roller 5. The housing of the motor 6 is fixedly connected to the first container 3, and a feeding plate 7 is provided at the outlet of the first container 3. The shell-peeling device 2 includes a second container 8 with a second inlet 9 connected to the feeding plate 7. The second container 8 has a pressurizing pipe 10 and a pressure-relief pipe 11. The second container 8 is rotatably connected to a rotating plate 12. The second container 8 has an arc-shaped protrusion 13 corresponding to the rotating plate 12 inside. A first sealing block 14 is provided at the second inlet 9, and a second sealing block 15 is provided at the outlet of the second container 8. Both the first sealing block 14 and the second sealing block 15 are provided with quick-release devices 16. A filter screen 30 and a dust-removing device 31 are fixedly connected to both the pressurizing pipe 10 and the pressure-relief pipe 11.

[0029] Using the aforementioned device, hazelnuts undergo pre-treatment by cracking their shells before being pressurized for efficient peeling. The hazelnuts to be processed are fed into the first inlet 4 of the first container 3, and the motor 6 drives the elastic roller 5 to rotate. The elastic roller 5 utilizes its own elastic properties to generate appropriate pressure upon contact with the hazelnuts, preventing the hazelnut kernels from being crushed while simultaneously creating uniform cracks on the hazelnut shells through rolling pressure, thus reducing the difficulty of subsequent peeling. After cracking, the hazelnuts pass through the feeding plate 7 at the outlet of the first container 3 and then through the second inlet 9 into the second container 8 of the peeling device 2. Once in the second container 8, the second inlet 9 and outlet are sealed by the first sealing block 14 and the second sealing block 15, creating a sealed space within the second container 8. The pressurization pipe 10 is connected to a pressurization device, and the depressurization pipe 11 is connected to a depressurization device. Pressurization pipe 10 slowly pressurizes the sealed second container 8 to prevent excessive pressure difference between the inside and outside of the hazelnut shells, which could crush the shells and damage the kernels. High-pressure gas is slowly introduced into the hazelnut shells. Once the high-pressure gas has completely filled the shells, the pressure in the second container 8 is quickly reduced through the depressurization pipe 11. This creates a pressure difference between the inside and outside of the hazelnut shells, causing the already cracked shells to burst open. After the bursting, a hand-cranked shaft controls the rotation of the rotating plate 12. Rotating the rotating plate 12, which engages with the arc-shaped protrusion 13 inside the second container 8, causes it to tilt slowly. The shelled hazelnuts and shells then slide out of the second container 8. The subsequent process involves a drum separator (not shown in the diagram) separating the hazelnuts and shells. The drum separator is existing technology and will not be described in detail here.

[0030] Optionally, the quick-release device 16 includes a hand-tightening part 17, one end of a spring 18 is fixedly connected to the hand-tightening part 17, the other end of the spring 18 is fixedly connected to a connecting frame 19, the hand-tightening part 17 is fixedly connected to a limiting shaft 20, the connecting frame 19 is sleeved with the limiting shaft 20, and both the first container 3 and the second container 8 are provided with grooves 21 corresponding to the limiting shaft 20.

[0031] With the above-described device, the end of the limiting shaft 20 that mates with the groove 21 is rectangular. The first container 3 or the second container 8 has a rectangular slot that is longer and wider than the limiting shaft 20, but shorter in width. The end is first pressed against the hand-tightening part 17, causing the limiting shaft 20 to extend into the slot of the first container 3 or the second container 8. Figure 4 As shown in the middle limit shaft 20, the spring 18 is compressed at this time. Then, by turning the hand-operated part 17, the limit shaft 20 rotates, as shown. Figure 4 As shown by the dashed line, the limiting shaft 20 is locked and, under the influence of spring pressure, generates friction with the groove 21, preventing uncontrolled rotation of the limiting shaft 20 and thus preventing the quick-release device 16 from loosening. In this way, the first sealing block 14 or the second sealing block 15 is fixed to the first container 3 or the second container 8, completing the limiting action. The portion of the first sealing block 14 or the second sealing block 15 that inserts into the first container 3 or the second container 8 is made of rubber to improve the airtightness of the device.

[0032] Optionally, the groove 21 includes an arc-shaped groove 22 and a rectangular groove 23.

[0033] Through the above-mentioned device, such as Figure 4 As shown, the arc-shaped groove 22 is used to further prevent the limiting shaft 20 from rotating, and the rectangular groove 23 is the empty groove of the first container 3 or the second container 8.

[0034] Optionally, the dust removal device 31 includes a rectangular shell 24, which is fixedly connected to the filter screen 30. One end of the rectangular shell 24 is fixedly connected to an elastic shaft 25, and the other end of the elastic shaft 25 is fixedly connected to a moving block 26. The moving block 26 is slidably connected to the rectangular shell 24. A hammer 27 is fixedly connected to the moving block 26. The moving block 26 is provided with teeth 28. The rectangular shell 24 is rotatably connected to a half gear 29 corresponding to the teeth 28. The half gear 29 is fixedly connected to the output end of a micro motor 32. The housing of the micro motor 32 is fixedly connected to the rectangular shell 24.

[0035] Through the above device, the micro motor drives the half gear 29 to rotate, the half gear 29 drives the moving block 26 to translate and compress the elastic shaft 25. When the moving block 26 moves to the top, the half gear 29 also disengages from the teeth of the moving block 26. The moving block 26 is bounced back by the elastic shaft 25 and hits the hammer 27 against the filter screen 30, shaking off the dust accumulated on the filter screen 30.

[0036] Optionally, the ash-vibrating device 31 is provided with multiple sets.

[0037] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
