Description

Technical Field

[0001] This utility model relates to the technical field of walnut processing equipment, specifically a walnut shelling and sorting machine. Background Technology

[0002] A walnut shelling and sorting machine is a fully or semi-fully automated mechanical device specifically designed for walnut processing. It is mainly used to achieve efficient shelling, kernel separation, and sorting of walnuts. It effectively improves walnut processing efficiency and reduces labor costs by using technologies such as physical extrusion, vibration screening, and wind sorting.

[0003] However, existing walnut shelling and sorting machines, when walnuts are poured into the machine for shelling, do not sort the walnuts by size beforehand. This causes walnuts of different sizes to pass through the physical extrusion structure simultaneously. When the size difference of the walnuts is too large, the physical extrusion structure is prone to jamming or even malfunction. In addition, after the initial extrusion, the shells of the walnuts are not completely separated from the kernels. This results in walnut shells still sliding out with the kernels at the kernel outlet, which is not conducive to the collection of the shelled kernels. Utility Model Content

[0004] The purpose of this utility model is to provide a walnut shelling and sorting machine to solve the problems mentioned in the background art, such as the easy jamming or even malfunction of the extrusion structure when walnuts of different sizes are extruded simultaneously, and the failure of the walnut shell and kernel to separate after extrusion, which affects the collection of walnut kernels.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a walnut shelling and sorting machine, comprising a box shell, a feeding hopper at the top of the box shell, a feeding port on one side of the bottom of the feeding hopper, a screening hopper below the feeding port, a plurality of screening holes at the bottom of the screening hopper, a receiving hopper below the screening hopper, a partition in the middle of the inner side of the receiving hopper, a baffle at the bottom of the receiving hopper, a miniature electric push rod on one side wall of the receiving hopper, and a first rotating roller and a second rotating roller respectively at the bottom of the receiving hopper, with rotating blocks at both ends of the first rotating roller and the second rotating roller;

[0006] Gear rings are provided on the outer walls of one shaft end of both the first and second rotating rollers. A feeding hopper is provided at the bottom of the first and second rotating rollers, and a discharge hopper is provided at the bottom end of the feeding hopper. A rotating cylinder is rotatably connected to one side wall of the discharge hopper. Spiral blades are provided on the inner wall of the rotating cylinder. A discharge port is provided at the connection between the rotating cylinder and the housing. A fan is installed at the bottom of the front side of the housing. A discharge hopper is provided at the bottom of one side wall of the housing. A discharge port is provided at the connection between the discharge hopper and the housing. A rotary motor is installed on the back side of the housing. A pulley is provided at the output end of the rotary motor.

[0007] Preferably, the air outlet of the blower is provided with a protective net, and the air outlet of the blower is connected to the interior of the discharge hopper.

[0008] Preferably, the top of the discharge hopper and one side wall are provided with openings. The discharge hopper is connected to the feed hopper through the opening at the top and is connected to the interior of the rotating drum through the opening on one side wall.

[0009] Preferably, the plurality of screening holes are arranged sequentially along the bottom end of the screening hopper, and the size of the plurality of screening holes gradually increases from left to right.

[0010] Preferably, the output end of the miniature electric push rod is fixedly connected to the middle of one side wall of the baffle, and the baffle is slidably connected to the receiving hopper through the miniature electric push rod.

[0011] Preferably, the gear ring on the rotating block at one end of the first rotating roller meshes with the gear ring on the rotating block at one end of the second rotating roller, the rotating block on the first rotating roller is rotatably connected to the pulley via a belt, and the first and second rotating rollers are rotatably connected to the housing via the pulley and the gear ring.

[0012] Preferably, the outer wall of the rotating drum near the outlet is also provided with a pulley, and the two pulleys are rotatably connected by a belt, and the rotating drum is rotatably connected to the shell through the pulley.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This walnut shelling and sorting machine, through the setting of screening hopper, partition, baffle and mini electric push rod, allows walnuts to be separated into two categories with small size difference after entering the machine. They are temporarily stored in the receiving hopper. Then, walnuts of similar size are shelled at the same time, avoiding the shelling of walnuts with large size difference at the same time, thereby reducing the probability of jamming or even failure of the physical extrusion structure in the machine.

[0015] 2. This walnut shelling and sorting machine, through its feeding hopper, discharging hopper, rotating drum, and spiral blades, ensures that after the walnuts complete the shelling process, they first fall onto the feeding hopper. The shells collide with the inner wall of the feeding hopper, loosening any remaining outer shells. The walnuts then slide from the feeding hopper into the discharging hopper, where they collide again with the inner wall, causing the outer shells to detach. A blower then blows the shells into the rotating drum, separating them from the kernels. This reduces the probability of shells sliding out with the kernels at the outlet, facilitating subsequent kernel collection. Attached Figure Description

[0024] like Figures 1 to 4 As shown, the walnut shelling and sorting machine of this embodiment includes a housing 1. A feeding hopper 2 is located at the top of the housing 1. The walnuts to be shelled in this application are paper-shelled walnuts. A feeding inlet 5 is located on one side of the bottom of the feeding hopper 2. A screening hopper 6 is located below the feeding inlet 5. The screening hopper 6 is inclined, with the higher side located below the feeding inlet 5 and the lower side away from the feeding inlet 5. Multiple screening holes 7 are located at the bottom of the screening hopper 6. A receiving hopper 8 is located below the screening hopper 6. The top and bottom of the receiving hopper 8 are open, allowing the walnuts to slide smoothly into or out of the bottom of the receiving hopper 8. The inner side of the receiving hopper 8... A partition 9 is provided in the middle of the receiving hopper 8, which divides the interior of the receiving hopper 8 into two parts, so that walnuts of similar size can be placed in the same part, thus facilitating the subsequent simultaneous shelling of walnuts of similar size. A baffle 11 is provided at the bottom of the receiving hopper 8, which blocks part of the bottom of the partition 9, so that the two parts of walnuts in the receiving hopper 8 can be shelled in sequence. A miniature electric push rod 10 is provided on one side wall of the receiving hopper 8. A first rotating roller 12 and a second rotating roller 13 are respectively provided at the bottom of the receiving hopper 8. A rotating block 14 is provided at both ends of the shaft of the first rotating roller 12 and the second rotating roller 13.

[0025] Gear rings 15 are provided on the outer walls of one shaft end of the first roller 12 and the second roller 13. A feeding hopper 21 is provided at the bottom of the first roller 12 and the second roller 13. The inner wall of the feeding hopper 21 is smooth and impact-resistant. The feeding hopper 21 is connected to the housing 1 by an elastic rope, allowing it to shake slightly when impacted by falling walnuts, thus facilitating the separation of the walnut shell from the kernel. A discharge hopper 22 is provided at the bottom of the feeding hopper 21. The discharge hopper 22 has a tubular structure, allowing one end of the rotating drum 19 to connect to the discharge hopper 22, facilitating stable rotation of the rotating drum 19. One end of the discharge hopper 22... A rotating drum 19 is rotatably connected to the side wall. The inner wall of the rotating drum 19 is provided with a spiral blade 20. The rotating drum 19 and the spiral blade 20 can transfer the walnut shells blown by the blower 3 towards the shell outlet 18, which is more conducive to the separation of the walnut shells from the walnut kernels. The shell outlet 18 is opened at the connection of the box shell 1. The blower 3 is installed at the bottom of the front of the box shell 1. The air inlet of the blower 3 is located on the front of the box shell 1. The bottom of one side wall of the box shell 1 is provided with a discharge hopper 22. The discharge outlet 4 is opened at the connection between the discharge hopper 22 and the box shell 1. A rotary motor 16 is installed on the back of the box shell 1. A pulley 17 is provided at the output end of the rotary motor 16.

[0026] Specifically, the air outlet of the blower 3 is equipped with a protective net. The air outlet of the blower 3 is connected to the inside of the discharge hopper 22. The function of the protective net is to prevent the walnuts that slide from the feed hopper 21 into the discharge hopper 22 from falling into the blower 3, thereby protecting the blower 3.

[0027] Furthermore, the top of the discharge hopper 22 and one side wall are provided with openings. The discharge hopper 22 is connected to the feed hopper 21 through the opening at the top and is connected to the inside of the rotating drum 19 through the opening on one side wall. The function of the discharge hopper 22 is to allow the walnut shell covering the walnut kernel to collide again, thereby facilitating the separation of the walnut shell from the walnut kernel.

[0028] Furthermore, multiple sieve holes 7 are arranged sequentially along the bottom of the sieve hopper 6. The size of the multiple sieve holes 7 gradually increases from left to right. The diameter of the sieve holes 7 near the higher side of the sieve hopper 6 is smaller, and the diameter of the sieve holes 7 near the lower side of the sieve hopper 6 is larger. This allows the larger walnuts to fall into the area where the partition plate 9 and the baffle plate 11 are located when the walnuts slide down the sieve hopper 6, thereby achieving the classification and sequential shell breaking of the walnuts.

[0029] Furthermore, the output end of the micro electric push rod 10 is fixedly connected to the middle of one side wall of the baffle 11. The baffle 11 is slidably connected to the receiving hopper 8 through the micro electric push rod 10. The function of the micro electric push rod 10 is to push the baffle 11 to slide along the bottom of the receiving hopper 8, thereby realizing the sequential opening of the bottom of the receiving hopper 8.

[0030] Furthermore, the gear ring 15 on the rotating block 14 at one end of the first rotating roller 12 meshes with the gear ring 15 on the rotating block 14 at one end of the second rotating roller 13. The rotating block 14 on the first rotating roller 12 is rotatably connected to the pulley 17 via a belt. The first rotating roller 12 and the second rotating roller 13 are rotatably connected to the housing 1 via the pulley 17 and the gear ring 15. The gear ring 15 enables the first rotating roller 12 and the second rotating roller 13 to mesh and rotate in opposite directions, thereby achieving physical compression to break the shell of the walnut.

[0031] Furthermore, the outer wall of the rotating drum 19 near the shell outlet 18 is also equipped with a pulley 17. The two pulleys 17 are rotatably connected by a belt. The rotating drum 19 is rotatably connected to the shell 1 through the pulleys 17. The pulleys 17 on the rotating drum 19 can be driven to rotate by the belt, thereby realizing the rotation of the spiral blades 20 inside the rotating drum 19, which in turn facilitates the conveying of the walnut shells blown into the rotating drum 19 to the shell outlet 18.

[0032] The usage method of this embodiment is as follows: When using this walnut shelling and sorting machine, the machine needs to be connected to an external power supply first. Then, the rotary motor 16 can be started. At this time, the rotary motor 16 will drive the pulley 17 to rotate, so that the belt on the pulley 17 will simultaneously drive the rotating block 14 on the second roller 13 and the pulley 17 on the rotating drum 19 to rotate. This causes the gear ring 15 on the rotating block 14 of the second roller 13 to mesh with the gear ring 15 on the rotating block 14 of the first roller 12 to rotate. At this time, the first roller 12 and the second roller 13 will rotate in opposite directions, and the rotating drum 19 will rotate along one side of the discharge hopper 22. Then, the paper-shelled walnuts are poured into the feed hopper 2, so that the walnuts slide along the bottom of the feed hopper 2 into the feed inlet 5. Then, the walnuts will pass through the feed inlet 5 and fall into the screening hopper 6, and then slide down along the screening hopper 6. At this time, walnuts of different sizes will pass through the screening holes 7 of the corresponding diameter. Then, the smaller and similar-sized walnuts will pass through the receiving hopper 8. The walnuts fall directly onto the first roller 12 and the second roller 13 for shell breaking. Larger walnuts that are close in size will be intercepted by the partition 9 and the baffle 11 and left in the receiving hopper 8. After the small walnuts have finished shell breaking, the electric push rod will push the baffle 11 to slide, so that the large walnuts intercepted by the baffle 11 will fall from the bottom of the receiving hopper 8 into the space between the first roller 12 and the second roller 13 for shell breaking. Then, the shelled walnuts will fall into the discharge hopper 21. At this time, the walnut shells covering the kernels will collide with the inner wall of the discharge hopper 21, causing the walnut shells to loosen. Then, the walnuts will fall into the discharge hopper 22. At this time, the walnut shells covering the kernels will collide with the inner wall of the discharge hopper 22 again, causing the walnut shells to separate from the kernels. Then, the high-speed airflow blown by the blower 3 will blow the separated shells into the rotating drum 19, so that the shells in the rotating drum 19 will be transported to the shell outlet 18 by the spiral blades 20 on the inner wall of the rotating drum 19, until the shells are discharged from the shell outlet 18.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
