A chestnut shelling device

Abstract

This utility model provides a chestnut shelling device, relating to the field of chestnut production technology. It includes a frame, with a vibrating shelling assembly mounted on the upper side of the support. Limiting slide rods are welded to the upper side of the support, and sliding sleeves are provided on the surfaces of the limiting slide rods. A kneading box is welded to the upper side of the sliding sleeves. In this chestnut shelling device, after the chestnuts are placed into the kneading box, a rotating motor drives a secondary shaft plate to reciprocate via a primary shaft plate and a shaft column. The secondary shaft plate then drives the kneading box to vibrate via the box support column. The kneading box slides back and forth along the limiting slide rods via the sliding sleeves. As the kneading box reciprocates, the chestnuts continuously rub against the peeling mesh within the inclined kneading box and collide multiple times with the collision strips, gradually cracking the outer shell. The chestnut flesh, being heavier than the shell, naturally detaches, thus achieving the effect of chestnut shelling.

Description

Technical Field

[0001] This utility model relates to the field of chestnut production technology, and in particular to a chestnut shelling device. Background Technology

[0002] Chestnuts are a popular nut food, rich in nutrients, including starch, protein, various vitamins and minerals, and have high health benefits. Therefore, they occupy an important position in the consumer market. Chestnuts are usually covered by a two-layer shell structure: an outer shell with spiky hair and an inner shell with hard texture. After harvesting, farmers usually remove the outer shell and retain the inner shell to extend the shelf life and storage stability of chestnuts, making them easier to transport and sell.

[0003] However, existing chestnut shelling methods mainly rely on manual peeling using tools such as pliers or mechanical crushing by large equipment. In actual peeling, manual operation is slow and labor-intensive. Crushing can easily cause the chestnut flesh to break or become severely deformed. Furthermore, when dealing with chestnuts that already have a small opening, it is not easy to separate the chestnut shell from the flesh, resulting in incomplete separation of the flesh and shell.

[0004] Therefore, we provide a chestnut shelling device to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a chestnut shelling device, which aims to solve the aforementioned problems.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: It includes a frame, a bracket welded to the upper side of the frame, a vibrating shelling assembly disposed on the upper side of the bracket, a limiting slide rod welded to the upper side of each bracket, a sliding sleeve disposed on the surface of each limiting slide rod, a kneading box welded to the upper side of each sliding sleeve, a chestnut pre-opening assembly disposed on the left side of the frame, a separating rod plate disposed on the right side of the frame, and a pulp storage box disposed below the separating rod plate.

[0007] Preferably, the sliding sleeve and the limiting slide rod are sleeved together, the sliding sleeve is arranged in two sets, the kneading box moves back and forth along the limiting slide rod through the sliding sleeve, and the kneading box is tilted to the right.

[0008] Preferably, a box support column is welded in the middle of the kneading box, a secondary shaft plate is connected to the lower side of the box support column, a shaft column is connected to the end of the secondary shaft plate, a primary shaft plate is connected to the lower side of the shaft column, and a rotary motor is connected to the end of the primary shaft plate. The rotary motor drives the kneading box as a power source to reciprocate through the primary shaft plate and the secondary shaft plate.

[0009] Preferably, the inner side of the kneading box is welded with a stripping wire mesh, and the middle of the stripping wire mesh is provided with a collision strip.

[0010] Preferably, a feeding chute is welded to the top left side of the frame, and a clamping shaft is axially connected to the top of the feeding chute. A shaft motor is axially connected to the outer side of the clamping shaft.

[0011] Preferably, the surfaces of the clamping shafts are all bonded with protective rubber pads, which are made of soft rubber.

[0012] Preferably, the separating rod plate is welded to the frame, the separating rod plate has a comb-like structure, the gap distance of the separating rod plate is greater than the diameter of the pulp and less than the diameter of the shell, and the separating rod plate has an inclined structure.

[0013] This invention provides a chestnut shelling device. Compared with the prior art, it has the following advantages:

[0014] 1. This chestnut shelling device involves placing chestnuts into a kneading box. A rotating motor drives a secondary shaft plate to reciprocate through a primary shaft plate and a shaft column. The secondary shaft plate then drives the kneading box to vibrate through the box support column. The kneading box slides back and forth along a limiting slide rod via a sliding sleeve. As the kneading box reciprocates, the chestnuts continuously rub against the peeling mesh and collide with the collision strips within the inclined kneading box, causing the outer shell to gradually crack. At this point, the chestnut flesh, being heavier than the shell, naturally separates, thus achieving the effect of shelling the chestnuts.

[0015] 2. This chestnut shelling device involves pouring the chestnuts to be shelled into the clamping shaft. At this time, the shaft motor drives the clamping shaft to start rotating. The squeezing force between the two sets of clamping shafts further presses open the already opened chestnut shells, facilitating subsequent collision shelling. When the clamping shaft rotates, due to the certain differences in the size of the chestnuts, the protective rubber pad outside the clamping shaft can be adjusted to a certain extent to ensure that chestnuts of different sizes can be stably clamped.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 This utility model provides a technical solution: a chestnut shelling device, including a frame 1, a bracket 2 welded to the upper side of the frame 1, a vibrating shelling component 3 provided on the upper side of the bracket 2, a limiting slide rod 301 welded to the upper side of each bracket 2, a sliding sleeve 302 provided on the surface of each limiting slide rod 301, a kneading box 303 welded to the upper side of the sliding sleeve 302, a chestnut pre-opening component 4 provided on the left side of the frame 1, a separating rod plate 5 provided on the right side of the frame 1, and a pulp storage box 6 provided on the lower side of the separating rod plate 5.

[0024] The sliding sleeve 302 is sleeved with the limiting slide bar 301. The sliding sleeve 302 is arranged in two sets. The kneading box 303 moves back and forth along the limiting slide bar 301 through the sliding sleeve 302. The kneading box 303 is tilted to the right.

[0025] When needed, chestnuts are placed into the kneading box 303. As the kneading box 303 is driven by the rotary motor 308, it slides back and forth along the limit slide bar 301 via the sliding sleeve 302. At this time, the chestnuts can be made to move back and forth within the kneading box 303 by the tilt angle of the kneading box 303, thereby causing collision and shelling. The chestnuts are then fed out by the tilt of the kneading box 303.

[0026] A box support column 304 is welded in the middle of the kneading box 303. A secondary shaft plate 305 is connected to the lower side of the box support column 304. A shaft column 306 is connected to the end of the secondary shaft plate 305. A primary shaft plate 307 is connected to the lower side of the shaft column 306. A rotary motor 308 is connected to the end of the primary shaft plate 307. The rotary motor 308 drives the kneading box 303 as a power source to reciprocate through the primary shaft plate 307 and the secondary shaft plate 305.

[0027] When needed, the rotating motor 308 drives the secondary shaft plate 305 to reciprocate through the primary shaft plate 307 and the shaft column 306. At this time, the secondary shaft plate 305 will drive the kneading box 303 to slide back and forth along the limit slide bar 301 through the box support 304, thereby realizing continuous kneading and collision shelling of chestnuts.

[0028] The inner side of the kneading box 303 is welded with a stripping wire mesh 309, and a collision strip 310 is provided in the middle of the stripping wire mesh 309.

[0029] When needed, as the kneading box 303 reciprocates, the chestnuts rub against the peeling wire mesh 309 repeatedly inside the inclined kneading box 303 and collide with the collision strip 310 multiple times. The shells gradually crack, and the chestnut meat, being heavier than the shell, will naturally detach, thus achieving the effect of peeling chestnuts.

[0030] A feeding chute 401 is welded to the top left side of the frame 1. A clamping shaft 402 is axially connected to the top of the feeding chute 401. A shaft motor 404 is axially connected to the outer side of the clamping shaft 402.

[0031] When needed, the chestnuts to be shelled are poured into the clamping shaft 402. At this time, the shaft motor 404 will drive the clamping shaft 402 to start rotating. The squeezing force between the two sets of clamping shafts 402 will further press open the already opened chestnut shells, making it easier to remove the shells by collision.

[0032] Protective rubber pads 403 are adhered to the surface of the clamping shaft 402. The protective rubber pads 403 are made of soft rubber.

[0033] When the clamping shaft 402 rotates, the protective rubber pad 403 outside the clamping shaft 402 can be adjusted to a certain extent due to the difference in the size of the chestnuts, so that chestnuts of different sizes can be stably clamped.

[0034] The separation rod plate 5 is welded to the frame 1. The separation rod plate 5 has a comb-like structure. The gap distance of the separation rod plate 5 is greater than the diameter of the pulp and less than the diameter of the shell. The separation rod plate 5 has an inclined structure.

[0035] After the chestnuts are shelled, because the volume of the shell is larger than that of the flesh, the shell is blocked by the comb-like structure of the separating rod plate 5, while the flesh falls through the gap into the flesh storage box 6 below, and the shell is discharged, thus achieving the purpose of separating the flesh and the shell.

[0036] Working principle: When needed, place the frame 1 in the desired position, and then pour the chestnut with the opening into the clamping shaft 402. At this time, the shaft motor 404 drives the clamping shaft 402 to rotate, and the protective rubber pad 403 outside the clamping shaft 402 will squeeze the chestnut, thereby making the opening larger. Then the chestnut falls into the feeding chute 401 and finally slides into the kneading box 303.

[0037] When the chestnut falls into the kneading box 303, the rotary motor 308 starts, driving the primary shaft plate 307 to rotate. The primary shaft plate 307 drives the secondary shaft plate 305 to rotate via the shaft column 306. The secondary shaft plate 305 then drives the kneading box 303 to reciprocate along the limiting slide bar 301 on the bracket 2 in conjunction with the sliding sleeve 302 via the box support column 304. At this time, the chestnut will move back and forth in the kneading box 303. During the movement, it will be restricted in the middle of the peeling mesh 309. When it collides along the peeling mesh 309, it will impact the collision strip 310, thereby achieving the effect of separating the pulp from the shell. Finally, by tilting the kneading box 303 itself, the pulp and shell are sent out of the kneading box 303.

[0038] After the pulp and shell are sent out of the kneading box 303, the pulp and shell will fall onto the separating rod plate 5. Since the diameter of the shell is larger than the gap of the separating rod plate 5, the pulp will fall into the pulp storage box 6, while the shell will slide out along the inclined surface of the separating rod plate 5, thereby achieving the effect of separating the pulp and shell. This completes the use of a chestnut shelling device.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
