Description

Technical Field

[0001] This utility model relates to the field of chestnut shelling technology, and in particular to a lever-type friction-type chestnut shell and kernel separation device. Background Technology

[0002] Chestnuts are nutritious and widely loved. However, the hard shell of chestnuts makes shelling and extracting the kernel a challenge in chestnut processing. Currently, chestnut shelling is mainly done manually, which is costly and inefficient.

[0003] Existing mechanical vibration separation equipment, which separates chestnut shells and kernels through mechanical vibration, results in a high rate of damage to chestnut kernels because the shells are peeled in batches and some already peeled chestnuts are still subjected to vibration and impact. On the other hand, mechanical extrusion separation equipment usually has a relatively fixed extrusion force. For hard-shelled chestnuts, the force is insufficient, resulting in incomplete peeling. For soft-shelled chestnuts or chestnuts with cracked shells, excessive extrusion can damage the chestnut kernels. Furthermore, when dealing with batches of chestnuts of different sizes, a complex disassembly and reassembly process is required, which is time-consuming and labor-intensive and not conducive to continuous production operations.

[0004] Therefore, we provide a lever-type friction chestnut shell and kernel separation device to solve the above problems. Utility Model Content

[0013] This utility model provides a lever-type friction-type chestnut shell and kernel separation device. Compared with the prior art, it has the following advantages:

[0014] 1. This lever-type friction chestnut shell and kernel separation device, during the chestnut peeling process, uses the elastic tension provided by the tension spring to automatically adjust the tilt angle of the separation fork according to the hardness of the chestnut shell, thus effectively peeling the chestnut shell without causing excessive damage to the chestnut kernel. Simultaneously, during use, the installation position of the fork limit plate can be adjusted vertically according to the size of the chestnut through the cooperation of the fixed connecting plate and locking bolts, thereby adjusting the initial tilt angle and pressure of the separation fork. This ensures rapid peeling of chestnuts of different sizes, avoiding excessive initial tilt angle of the separation fork when the chestnut is large, which could damage the chestnut kernel after peeling, thus improving the chestnut peeling effect.

[0021] 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.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a lever friction type chestnut shell and kernel separation device, including a frame support leg 1, a mounting frame 2 fixedly connected to the top of the frame support leg 1, a friction peeling assembly 3 provided on the inner side of the mounting frame 2, the friction peeling assembly 3 including a conveyor belt 301 installed on the inner side of the mounting frame 2, a conveyor motor 302 for driving the conveyor belt 301 installed on the left side of the mounting frame 2, a motor bracket 303 welded to the upper side of the mounting frame 2, a rotating connecting shaft 305 installed at the center of the bottom end of the motor bracket 303, a rotating horizontal shaft 306 passing through the lower end of the rotating connecting shaft 305, a separation fork 307 installed on the outer side of the rotating horizontal shaft 306, and a cleaning and unloading assembly 4 provided on the right side of the mounting frame 2.

[0023] The conveyor belt 301 is made of rubber. The top of the motor bracket 303 is equipped with a drive motor 304. The rotating connecting shaft 305 is connected to the motor bracket 303 by a bearing and passes through the motor bracket 303 to connect to the output end of the drive motor 304. The separation fork 307 forms a rotating structure with the conveyor belt 301 through the rotating connecting shaft 305.

[0024] During use, the open, cooked chestnuts are placed on the conveyor belt 301. Then, the conveyor belt 301 is driven by the conveyor motor 302, which moves the chestnuts toward the friction shelling assembly 3. When the chestnuts move to the position of the separating fork 307, the drive motor 304 drives the rotating connecting shaft 305 to rotate, which in turn drives the separating fork 307 to rotate clockwise. This generates friction between the chestnut shells and the conveyor belt 301 and the rotating separating fork 307, causing the chestnut shells and kernels to separate.

[0025] The separation fork 307 is rotatably connected to the rotating connecting shaft 305. There are two sets of separation forks 307, which are respectively distributed on both sides of the rotating horizontal shaft 306, and the two sets of separation forks 307 face opposite directions.

[0026] By setting the separation forks 307 on both sides of the rotating horizontal axis 306, the rotation is more stable and the chestnuts can be peeled continuously, thus improving the continuity of chestnut peeling.

[0027] A connecting rod 310 is welded to one end of the separation fork 307. A spring rod 311 is provided on the upper side of the rotating horizontal shaft 306. The spring rod 311 passes through the inner side of the rotating connecting shaft 305. A tension spring 312 is installed at the end of the connecting rod 310. The other end of the tension spring 312 is installed on the spring rod 311. A fork limiting plate 313 is provided on the lower side of the rotating horizontal shaft 306. The separation fork 307 tilts downward under the action of the tension spring 312.

[0028] During the chestnut peeling process, the elastic tension provided by the tension spring 312 can automatically adjust the tilt angle of the separating fork 307 according to the hardness of the chestnut shell. When encountering a harder chestnut shell, the tension spring 312 is stretched, the separating fork 307 is lifted, and the force applied to the chestnut shell is increased accordingly, ensuring that the chestnut shell can be effectively peeled off. Thus, the chestnut shell can be peeled off without causing excessive damage to the chestnut kernel. In addition, the fork limiting plate 313 limits the maximum downward tilt angle of the separating fork 307, preventing the separating fork 307 from tilting excessively and affecting the normal peeling work, thus ensuring the stability and reliability of the entire peeling process.

[0029] Both ends of the shift fork limit plate 313 are welded with fixed connecting plates 314. The surface of the fixed connecting plate 314 is provided with a connecting groove 315. The outer side of the fixed connecting plate 314 is provided with a locking bolt 316. The locking bolt 316 is threadedly connected to the rotating horizontal shaft 306 and the spring pull rod 311.

[0030] During use, the installation position of the fork limit plate 313 can be adjusted up and down according to the size of the chestnut by using the fixed connecting plate 314 and the locking bolt 316. This adjusts the initial tilt angle and pressure of the separating fork 307, ensuring that chestnuts of different sizes can be peeled quickly. This avoids the initial tilt angle of the separating fork 307 being too large when the chestnut is large, which could damage the chestnut kernel after peeling and improve the peeling effect.

[0031] The outer side of the separation fork 307 is fitted with a fork bushing 308, which is made of rubber. Each set of separation forks 307 has six forks, and each separation fork 307 is separated by a spacer sleeve 309.

[0032] During shelling, the chestnut gets stuck in the gap of the separating fork 307. Then, under the rotation of the separating fork 307 and the action of friction, the chestnut is gradually squeezed, thereby breaking the chestnut shell and separating the chestnut kernel from the shell. At the same time, depending on the size of the chestnut, the spacing between the separating forks 307 can be changed by installing spacers 309 of different widths between the separating forks 307, so as to facilitate the shelling of chestnuts of different sizes. Furthermore, the rubber fork bushing 308 improves the friction and squeezing effect on the chestnut while reducing damage to the chestnut kernel.

[0033] The cleaning and unloading assembly 4 includes a connecting bracket 401 snapped onto the inner side of the top of the frame support leg 1. A connecting bolt 402 is provided on the outer side of the frame support leg 1. The connecting bolt 402 passes through the frame support leg 1 and connects to the connecting bracket 401. An unloading plate 403 is welded to the upper side of the connecting bracket 401. A cleaning scraper 404 is provided at the bottom left side of the unloading plate 403. The cleaning scraper 404 is made of hard plastic and is in contact with the surface of the conveyor belt 301.

[0034] After the chestnuts are shelled, the conveyor belt 301 transports the shelled chestnuts to the cleaning and unloading assembly 4. The unloading plate 403 guides the chestnut shells and kernels from the conveyor belt 301 and unloads them into an external collection container. The hard plastic cleaning scraper 404 adheres tightly to the surface of the conveyor belt 301 to remove chestnut shell fragments and impurities adhering to the conveyor belt 301, preventing these residues from affecting the subsequent chestnut shelling effect. This ensures that the conveyor belt 301 is in a relatively clean state each time it runs, improving production efficiency and the quality of chestnut shelling.

[0035] Working principle: During use, open-shelled cooked chestnuts are placed on conveyor belt 301. Then, conveyor motor 302 drives conveyor belt 301, moving chestnuts toward friction shelling assembly 3. When the chestnuts move to the area where the separating fork 307 is located, drive motor 304 drives rotating connecting shaft 305 to rotate, thereby driving rotating horizontal shaft 306 and separating fork 307 mounted on it to make clockwise circular motion. At this time, the chestnuts will be stuck in the gap of separating fork 307. Then, under the action of rotation of separating fork 307 and friction, the chestnuts are gradually squeezed, thereby breaking the chestnut shell and separating the chestnut kernel from the shell. The chestnut kernels after shelling are smaller in size and will not be stuck by separating fork 307.

[0036] During the separation process, the tension spring 312 applies an elastic tension to the separation fork 307 through the connecting rod 310. When it encounters a chestnut shell with high hardness, the tension spring 312 is stretched and drives the separation fork 307 to lift upward at a certain angle, thereby increasing the force on the chestnut shell to ensure effective peeling. At the same time, the fork limiting plate 313 is fixed below the rotating horizontal shaft 306 through the fixed connecting plate 314 and the locking bolt 316, which limits the maximum downward tilt angle of the separation fork 307 and prevents it from pressing down too much and damaging the chestnut kernel.

[0037] After shelling, the chestnut shells and kernels continue to move along the conveyor belt 301 to the cleaning and unloading assembly 4. The unloading plate 403 guides the material to the external receiving container. At the same time, the cleaning scraper 404 made of hard plastic is in close contact with the surface of the conveyor belt 301 to scrape off the remaining chestnut shell debris and impurities, keeping the conveyor belt 301 clean for subsequent use.

[0038] 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.
