Description

Technical Field

[0001] This utility model relates to the field of walnut shelling technology, specifically a walnut shelling and kernel extraction device. Background Technology

[0002] The fruit of a walnut is a green, spherical structure called an inflorescence, which splits open when ripe to reveal the nut inside, which is what we commonly call a walnut. The nut has a hard outer shell, inside which is a kernel rich in oil. The kernel is rich in protein, fat, vitamins, minerals, and other nutrients, making it a highly nutritious food. Before eating walnuts, a walnut shelling device is needed to crack the shell to remove the kernel.

[0003] However, existing walnut shelling and kernel extraction devices, such as the Chinese utility model patent "A Manual Impact-Type Walnut Shelling and Kernel Extraction Machine" (Publication No. CN207100441U), have the following drawbacks:

[0004] (1) The existing walnut shelling and kernel extraction device has low shelling efficiency. When in use, it is necessary to manually place the walnuts one by one in the middle of the pressing plate, which results in a slow walnut placement speed and low walnut shelling efficiency.

[0005] (2) The existing walnut shelling and kernel extraction device has a weak function of separating broken shells. When using it, because a lot of small broken shells will be adsorbed on the walnut kernel after the walnut is shelled, it is impossible to separate the small broken kernels and broken shells, which makes it inconvenient for subsequent processing. Utility Model Content

[0006] The purpose of this invention is to provide a walnut shell-cracking and kernel-extracting device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A walnut shelling and kernel extraction device includes a working box, a loading shell mounted on the top of the working box, a hydraulic rod mounted on the bottom of the loading shell, a connecting block mounted on one end of the hydraulic rod, a pressing plate mounted on one side of the connecting block, a sliding rod mounted on one side of the pressing plate, a tamping rod connected to one end of the sliding rod, a feeding port on the top of the loading shell, a discharging port on one side of the loading shell, the bottom of the feeding port being arc-shaped, and a tamping hole on the side of the loading shell near the discharging port, with the sliding rod and the tamping rod slidably connected inside the tamping hole.

[0009] Preferably, a connecting rod is connected to the bottom of the connecting block, a baffle is installed at the bottom of the connecting rod, and both sides of the connecting rod and the outer surface of the baffle are slidably connected to the top of the work box.

[0010] Preferably, a positioning shell is installed on one side of the work box, a servo motor is installed on one side of the positioning shell, and a fan blade is installed on the rotating shaft of the servo motor.

[0011] Preferably, the working box has a ventilation hole on the side away from the positioning shell, and a filter screen is installed inside the ventilation hole and on the side of the positioning shell away from the servo motor.

[0012] Preferably, a shell-breaking plate is installed on the top of the working box away from the loading shell, and several shell-breaking blocks are installed at the bottom of one side of the shell-breaking plate.

[0013] Preferably, a surrounding plate is installed on the side of the shell-breaking plate near the shell-breaking block, and one side of the surrounding plate is installed on the side of the loading shell near the tamping hole.

[0014] Preferably, the work box has a door hinged to the front, and a partition is installed on the inner bottom wall of the work box.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This walnut shell-cracking and kernel-extracting device, with its loading shell, sliding rod, and tamping rod, allows for easy operation. Walnuts are placed in the inlet of the loading shell. A hydraulic rod is then activated, causing a connecting block to move the pressing plate in the opposite direction. This movement of the pressing plate moves the sliding rod and the tamping rod, pushing the walnuts out of the inlet through the outlet. The walnuts fall onto one side of the pressing plate, where the hydraulic rod moves the pressing plate forward, pushing the walnuts to the cracking plate and crushing them. After the walnuts are crushed, the hydraulic rod moves in the opposite direction, repeating the process. This eliminates the need for manual placement of the walnuts between the pressing plates, thus improving shell-cracking efficiency.

[0017] This walnut shelling and kernel extraction device, through the arrangement of a servo motor, fan blades, and baffles, works as follows: After the walnuts are crushed, the hydraulic rod reverses and drives the connecting block to move. The connecting block then drives the connecting rod and baffle to move. The movement of the baffle causes the crushed walnuts to be blocked by the shell on the working chamber, allowing the walnut kernels, shells, and debris to fall into the working chamber. At this point, the servo motor is activated, and its operation blows the walnut shells and kernels to the other side of the partition plate inside the working chamber, thereby separating the walnut shells, kernels, and crushed walnuts (using air separation) for easier subsequent operations.

[0023] 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.

[0024] Please see Figures 1-4 As shown, this utility model provides a walnut shelling and kernel extraction device, including a working box 1, a loading shell 2 installed on the top of the working box 1, a hydraulic rod 3 installed at the bottom of the loading shell 2, a connecting block 4 installed at one end of the hydraulic rod 3, a pressing plate 5 installed on one side of the connecting block 4, a sliding rod 6 installed on one side of the pressing plate 5, a tamping rod 7 connected to one end of the sliding rod 6, a feeding port 8 opened at the top of the loading shell 2, a discharging port 9 opened on one side of the loading shell 2, the bottom of the feeding port 8 is arc-shaped, a tamping hole opened on the side of the loading shell 2 near the discharging port 9, and the sliding rod 6 and the tamping rod 7 are slidably connected inside the tamping hole.

[0025] In this process, walnuts are placed in the feed inlet 8 on the loading shell 2. Then, the hydraulic rod 3 is activated, causing the connecting block 4 to move the pressing plate 5 in the opposite direction. As the pressing plate 5 moves, it also moves the sliding rod 6 and the tamping rod 7. One end of the tamping rod 7 pushes the walnuts in the feed inlet 8 out through the discharge outlet 9. At this time, the walnuts fall to one side of the pressing plate 5. Then, the hydraulic rod 3 moves the pressing plate 5 in the forward direction, pushing the walnuts to the shell-breaking plate 16, where they are squeezed and cracked. After the walnuts are cracked, the hydraulic rod 3 moves in the opposite direction, and the above steps are repeated. This eliminates the need for manual placement of walnuts between the pressing plates 5 for squeezing, thus improving the shell-breaking efficiency.

[0026] Specifically, a connecting rod 10 is connected to the bottom of the connecting block 4, and a baffle 11 is installed at the bottom of the connecting rod 10. Both sides of the connecting rod 10 and the outer surface of the baffle 11 are slidably connected to the top of the working box 1. A positioning shell 12 is installed on one side of the working box 1, and a servo motor 13 is installed on one side of the positioning shell 12. A fan blade 14 is installed on the rotating shaft of the servo motor 13. After the walnuts are crushed, when the hydraulic rod 3 moves in the reverse direction to drive the connecting block 4 to move, the connecting block 4 drives the connecting rod 10 and the baffle 11 to move. The movement of the baffle 11 causes the crushed walnuts to be blocked by the shell on the working box 1, so that the walnut kernels, walnut shells and debris fall into the working box 1. At this time, the servo motor 13 is started. The operation of the servo motor 13 blows the walnut shells and walnut kernels to the other side of the partition plate 20 inside the working box 1, thereby achieving the function of separating the walnut shells from the walnut kernels and the crushed walnuts, which is convenient for subsequent operations.

[0027] Furthermore, a ventilation hole is provided on the side of the working box 1 away from the positioning shell 12. A filter screen 15 is installed inside the ventilation hole and on the side of the positioning shell 12 away from the servo motor 13. The filter screen 15 prevents broken shells from escaping. The shell kernels are separated by air separation, which is a commonly used technical means in the field. It utilizes the different weights of the shell kernels and separates them by air force, such as the Chinese utility model patent "Walnut Shell Kernel Sorting Machine" (publication number CN201064774Y).

[0028] Furthermore, a shell-breaking plate 16 is installed on the top of the working box 1 on the side away from the loading shell 2, and several shell-breaking blocks 17 are installed on the bottom of one side of the shell-breaking plate 16. When the extrusion plate 5 extrudes the walnut, the shell-breaking blocks 17 make the walnut easier to crush.

[0029] It is worth noting that a surrounding plate 18 is installed on the side of the shell-breaking plate 16 near the shell-breaking block 17. One side of the surrounding plate 18 is installed on the side of the loading shell 2 near the tamping hole. A door 19 is hinged to the front of the working box 1. A partition plate 20 is installed on the inner bottom wall of the working box 1. With the setting of the surrounding plate 18, when the walnuts fall from the discharge port 9, they will not exceed the squeezing range of the extrusion plate 5. With the setting of the door 19, the shelled walnuts and broken kernels and shells in the working box 1 can be taken out.
