It is widely used in food processing plants, nut processing enterprises, and other fields. This equipment separates the walnut shell from the kernel using mechanical force, improving production efficiency and reducing labor costs.

[0003] Application No. 2022222523088 discloses a conical hammer-type walnut shelling machine, including a frame with a walnut core shelling area, an inlet, and an outlet. The walnut core shelling area includes a conical sleeve and a conical hammer. The conical hammer rotates under the drive of a drive mechanism, forming a compression with the conical sleeve to break the walnut shell. One end of the conical hammer can slide axially along the output shaft of the drive mechanism, and the other end is rotatably connected to an adjusting rod, which is used to adjust the distance between the conical hammer and the conical sleeve.

[0016] The principle of this utility model: To solve the problems of low walnut kernel integrity, excessive broken kernels, and low walnut kernel yield in existing walnut shelling machines, this utility model adopts the following technical solution: It uses a disc-type, single-walnut rolling shelling operation. A feeding machine sequentially feeds individual walnuts into the shelling assembly for shelling. The shelling assembly consists of a base plate, connecting plate A, shell-breaking plate A, rollers, upright plate, connecting plate B, shell-breaking plate B, limiting plate, screw B, and spring. Connecting plate A is parallel to the base plate. One end of connecting plate A is rotatably connected to the base plate, and the other end is detachably connected to shell-breaking plate A. Rollers are rotatably connected to the top of shell-breaking plate A. The upright plate is connected to the base plate... The plates are vertically connected. One end of connecting plate B is rotatably connected to the upright plate, and the other end is rotatably connected to a roller. A shell-breaking plate B is detachably connected to one side of connecting plate B. A limit plate with an oblong hole is located on the back of connecting plate B. One end of screw B is connected to the base plate, and the other end passes through the oblong hole. A nut is screwed into the end of screw B. There is a spring between the limit plate and the base plate. There is a tension spring between shell-breaking plate A and the upright plate of another shell-peeling component. Shell-breaking plates A and B are set at an angle, forming a funnel-shaped space between them. Under the action of gravity, the walnut is always at the bottom of the funnel-shaped space. That is to say, the walnut is in contact with shell-breaking plates A, B, and the base plate. When the walnut is put into this space, it is... As the disc and shaft rotate, the roller at the top of the shell-breaking plate A first rubs against the limiting block A at the top of the support. Connecting plate A rotates around the shaft, and shell-breaking plate A squeezes the walnut shell, completing the first shell-breaking. Subsequently, the disc and shaft continue to rotate, and the roller at the top of connecting plate B rubs against the limiting block B. Connecting plate B rotates around the shaft, and shell-breaking plate B squeezes the walnut shell again, completing the first shell-breaking. After being squeezed twice, the shell-breaking operation is complete. As the disc and shaft rotate, the walnut shells and kernels are thrown out from the shelling assembly. Using this technical solution, the squeezing force during the walnut shell-breaking process is controllable, preventing the walnut kernels from being crushed and allowing them to be extracted intact. The yield of walnut kernels is relatively high. Furthermore, to enhance the adaptability of this invention, the positions of limiting blocks A and B are adjustable. By adjusting their installation positions, the squeezing force of the shell-breaking plates A and B can be adjusted, allowing it to be applied to walnuts of different sizes and controlling the degree of walnut kernel crushing, thus meeting the processing needs of different enterprises. The shelling assembly and the disc are connected by bolts and nuts, making maintenance and replacement easy. Most of the components of the shelling assembly are bolted together, making repair and replacement simple when a component is damaged. Overall, this invention has low manufacturing costs, low maintenance difficulty, and stable and reliable operation.

[0017] The beneficial effects of this utility model are as follows: Compared with existing walnut shelling machines, this walnut shelling machine has the following advantages: 1. It adopts a single walnut rolling shelling operation, and the squeezing force during the shelling process is controllable, avoiding crushing the walnut kernel and allowing the walnut kernel to be extracted intact, resulting in a higher walnut kernel yield; 2. The squeezing force is adjustable, making it highly adaptable. It can be applied to walnuts of different sizes and can control the degree of walnut kernel crushing, meeting the processing needs of different enterprises; 3. It has low manufacturing cost, low maintenance difficulty, and stable and reliable operation. Attached Figure Description

Detailed Implementation

[0026] The specific implementation method of this utility model is as follows: Figures 1-7As shown, a walnut shelling machine includes a support frame 100, a shelling component fixing seat 200, and a shelling component 300. The support frame 100 is welded together from several vertical beams 101 and horizontal beams 102. Bearing seats 103 are fixed between the vertical beams 101. A limit block base 104 is located at the top of the support frame 100, and a limit block A105 is installed on the limit block base 104. Limit blocks B107 are installed on the vertical beams 101 on both sides of the support frame 100. The shelling component fixing seat 200... The shell-peeling assembly 300 consists of a disc 201, a rotating shaft 202, and a cover 203. The rotating shaft 202 is vertically mounted at the center of the disc 201, and the cover 203 is located at the edge of the disc 201. The shell-peeling assembly 300 consists of a base plate 301, a connecting plate A302, a shell-breaking plate A303, a roller 304, a vertical plate 305, a connecting plate B306, a shell-breaking plate B307, a limiting plate 308, a screw B309, and a spring 310. One end of the connecting plate A302 is connected to the base plate 301. The connecting plate B306 is rotatably connected to the shell-breaking plate A303 at one end and detachably connected to the shell-breaking plate A303 at the other end. A roller 304 is rotatably connected to the top of the shell-breaking plate A303. The upright plate 305 is perpendicularly connected to the base plate 301. One end of the connecting plate B306 is rotatably connected to the upright plate 305, and the other end is rotatably connected to the roller 304. A shell-breaking plate B307 is detachably connected to one side of the connecting plate B306. A limiting plate 308 is located on the back of the connecting plate B306, and the limiting plate 308 has an oblong hole. One end of rod B309 is connected to the base plate 301, and the other end passes through the waist-shaped hole. A nut is screwed into the end of the screw B309. A spring 310 is located between the limiting plate 308 and the base plate 301. The rotating shaft 202 is interference-fitted with the bearing in the bearing seat 103. One end of the rotating shaft 202 is connected to the power device. Several shelling components 300 are evenly fixed on both sides of the disc 201. A tension spring is located between the shell-breaking plate A303 and the upright plate 305 of another shelling component 300. In this embodiment, the walnut shelling method is a disc-type, single-walnut rolling shelling operation. The feeding machine puts a single walnut into the shelling component 300. After the shelling operation is completed, the walnut is thrown out of the shelling component 300 under the action of gravity.

[0027] Specifically, such as Figure 2 , Figure 4As shown, the base 104 of the limiting block has two through holes. A screw A106 is connected to the top of the limiting block A105. The screw A106 passes through the through holes and has a nut at its lower part. A nut is also tightened on the top of the limiting block A105. When the shelling assembly fixing seat 200 rotates, the roller 304 on the top of the shell-breaking plate A303 rubs against the limiting block A105, causing the connecting plate A302 and the shell-breaking plate A303 to swing and squeeze the walnut shell. In this embodiment, by adjusting the installation position of the limiting block A105, the force of the shell-breaking plate A303 squeezing the walnut can be adjusted, which can adapt to walnuts of different sizes and control the degree of walnut kernel crushing, meeting the processing needs of different enterprises. The limiting block A105 has an arc-shaped sheet structure, and its lowest point is lower than the rotation trajectory of the roller 304 on the top of the shell-breaking plate A303.

[0028] Specifically, such as Figure 2 , Figure 3 , Figure 4 As shown, the vertical beam 101 has two screw seats 108, each with a through hole at the top. Two screws A106 are connected to one side of the limiting block B107, passing through the through hole at the top of the screw seat 108. Two nuts are located on both sides of the screw seat 108 to secure the screws A106. When the shelling assembly fixing seat 200 rotates, the roller 304 on the top of the connecting plate B306 rubs against the limiting block B107, causing the shell-breaking plate B307 to swing and squeeze the walnut shell. In this embodiment, by adjusting the installation position of the limiting block B107, the force of the shell-breaking plate B307 squeezing the walnut can be adjusted, adapting to walnuts of different sizes and controlling the degree of walnut kernel crushing, thus meeting the processing needs of different enterprises. Figure 4 As shown, the limiting block B107 is made of bent sheet metal, with one end being arc-shaped, used to rub against the roller 304 on the top of the connecting plate B306. The distance between the rollers 304 on the top of the connecting plate B306 is greater than the distance between the arc-shaped segments of the limiting block B107.

[0029] Specifically, the power unit is connected to the input shaft of the reducer, and the output shaft of the reducer is connected to the rotating shaft 202. The power unit can be any one of an electric motor, a diesel engine, or a gasoline engine. In this embodiment, a wide range of power units can be selected, and users can choose different power units according to their own needs.

[0030] Specifically, the vertical beam 101 and the horizontal beam 102 are made of galvanized square tubing. In this embodiment, the vertical beam 101 and the horizontal beam 102 made of galvanized square tubing are readily available, have low manufacturing costs, and a long service life.

[0031] Specifically, such as Figure 1As shown, the cover 203 is a hollow cylindrical structure made of galvanized iron sheet, with holes drilled at the radial projection of the shelling assembly 300. In this embodiment, the cover 203 can shield other non-working areas, allowing the feeder to accurately feed the walnuts into the shelling assembly 300, thus improving the walnut shelling efficiency.

[0032] Specifically, such as Figure 6 , Figure 7 As shown, the contact surfaces of the shell-breaking plates A303 and B307 with the walnut are serrated. In this embodiment, the serrated contact surfaces of the shell-breaking plates A303 and B307 with the walnut concentrate the force when the walnut is squeezed by the shell-breaking plates A303 and B307, making it less prone to slipping and easier to break the walnut shell, thus preventing the walnut kernel from being crushed.

[0033] Specifically, the shell-breaking plates A303 and B307 are made of wear-resistant alloy steel. In this embodiment, the shell-breaking plates A303 and B307, made of wear-resistant alloy steel, have a long service life and low maintenance costs.

[0034] Specifically, such as Figure 5 As shown, the disc 201 has several studs on both sides, and the base plate 301 has through holes at corresponding positions. The base plate 301 and the disc 201 are tightened together by nuts. In this embodiment, the base plate 301 and the disc 201 are connected by bolts and nuts, making maintenance and replacement easier.

[0035] Specifically, such as Figure 7 As shown, the shell-breaking plate A303 and shell-breaking plate B307 are inclined. In this embodiment, a space with a larger upper part and a smaller lower part is formed between the shell-breaking plate A303 and the shell-breaking plate B307. After the walnut enters this space, the compression effect is sufficient. Under the weight of gravity, the walnut is always in close contact with the shell-breaking plate A303, the shell-breaking plate B307, and the bottom plate 301.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
