Description

Technical Field

[0001] This utility model relates to the field of walnut technology, specifically a flexible impact shell-breaking machine for walnuts. Background Technology

[0002] Walnut is a plant belonging to the genus Juglans in the family Juglandaceae. The trunk is shorter than other species, with a broad crown and grayish-green, hairless twigs; the leaflets are elliptic-ovate to oblong-elliptic, and the inflorescence is short; the fruit is nearly spherical, hairless, with a slightly wrinkled kernel and a short pointed tip; the septum is relatively thin, with no internal cavities, and the inner pericarp wall has irregular cavities.

[0003] A walnut shelling machine is a mechanical device specifically designed to crush the outer shells of nuts such as dried walnuts and hickory nuts, and separate the shells from the kernels. It is widely used in homes, small workshops, and nut processing plants.

[0004] However, existing walnut shelling machines exert a large impact force on the walnuts, easily breaking the kernels into small pieces; therefore, they do not meet the current needs. In response, we have proposed a flexible impact shelling machine for walnuts. Utility Model Content

[0005] The purpose of this invention is to provide a flexible impact shell-breaking machine for walnuts, in order to solve the problems mentioned in the background art, such as the large impact force applied to walnuts by existing shell-breaking machines, which easily crushes the walnut kernels into small pieces.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a walnut flexible impact shell-breaking machine, including a shell-breaking machine shell, an electronic weighing shell-breaking platform is provided inside the shell, an inverted conical walnut placement groove is provided at the middle position of the upper surface of the electronic weighing shell-breaking platform, and a discharge valve is fixedly installed at the middle position of the lower surface of the electronic weighing shell-breaking platform.

[0007] Above the inverted conical walnut placement slot is a drive motor fixedly installed inside the shell of the shell-crushing machine. Below the drive motor is a pressure-sensing conical shell-crushing plate. At the middle position of the upper surface of the pressure-sensing conical shell-crushing plate is a square slot that is connected to the shell of the shell-crushing machine via a threaded structure. Inside the square slot is a square rotating shaft that is connected to the output shaft of the drive motor via a coupling.

[0008] Preferably, the inner wall of the square slot has a square cross-sectional shape, the outer surface of the square rotating shaft fits against the inner wall of the square slot, and the square rotating shaft and the square slot are slidably connected.

[0009] Preferably, a vibrator is fixedly installed inside the shell of the shell-breaking machine on both sides below the electronic weighing shell-breaking platform, and the upper end surface of the vibrator is in contact with the lower end surface of the electronic weighing shell-breaking platform.

[0010] Preferably, a feeding port is fixedly installed on one side of the upper surface of the shell of the shell-breaking machine, and a rolling groove located inside the shell of the shell-breaking machine is provided below the feeding port. A cutting cylinder is fixedly installed inside the shell of the shell-breaking machine on one side of the rolling groove, and the piston rod of the cutting cylinder is connected to a cutting plate located inside the rolling groove.

[0011] Preferably, a mesh conveyor belt is provided below the electronic weighing and shell-breaking platform, and a walnut shell storage cart is provided below the mesh conveyor belt.

Multiple pressure sensors are installed inside the pressure-sensing conical shell-breaking plate, and the detection probes of the pressure sensors are located on the lower end surface of the pressure-sensing conical shell-breaking plate. A weighing sensor is installed inside the electronic weighing shell-breaking platform.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention involves pouring walnuts into the feeding inlet when the equipment is needed. The walnuts then flow along a chute into the electronic weighing and shelling platform. Once the platform is full, a drive motor rotates a pressure-sensing conical shelling plate located above the platform, moving it downwards. The downward movement of the plate is slow, ensuring a descent speed of one centimeter every five seconds. As the plate descends, it will contact... The process involves applying gentle, slow pressure to the walnut through a pressure-sensing conical shell-cracking plate. As the plate rotates, the walnut rotates along with it, applying rotational shear force. This technique causes cracks to gradually form and expand until the walnut shell completely breaks open, preventing the high-energy impact from the sudden shattering of the shell from being transmitted to the kernel and causing serious damage.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] The material cutting cylinder 4 (model SC-32), drive motor 10 (model DM542) and threaded rod 11 (model M10) mentioned in this utility model can be obtained from the market or through private customization.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, one embodiment of this utility model is provided: a walnut flexible impact shell-breaking machine, including a shell-breaking machine shell 1, an electronic weighing shell-breaking platform 9 is provided inside the shell-breaking machine shell 1, an inverted conical walnut placement groove 15 is provided at the middle position of the upper end face of the electronic weighing shell-breaking platform 9, and a discharge valve 16 is fixedly installed at the middle position of the lower end face of the electronic weighing shell-breaking platform 9.

[0024] Above the inverted conical walnut placement slot 15 is a drive motor 10 fixedly installed inside the shell-crushing machine housing 1. Below the drive motor 10 is a pressure-sensing conical shell-crushing plate 14. At the middle position of the upper end face of the pressure-sensing conical shell-crushing plate 14, a square slot 12 is fixedly connected to the shell-crushing machine housing 1 via a threaded structure. Inside the square slot 12 is a square rotating shaft 13 connected to the output shaft of the drive motor 10 via a coupling. A feeding port 3 is fixedly installed on one side of the upper end face of the shell-crushing machine housing 1. Below the feeding port 3 is a rolling groove located inside the shell-crushing machine housing 1. On one side of the rolling groove is a cutting cylinder 4 fixedly installed inside the shell-crushing machine housing 1. The piston rod of the cutting cylinder 4 is connected to a cutting plate 5 located inside the rolling groove. On one side of the feeding port 3 is a control panel 2 fixedly installed on the outer surface of the shell-crushing machine housing 1, and the shell-crushing machine housing 1 and the control panel 2 are electrically connected. The control panel 2 can control various mechanisms on the shell-crushing machine housing 1.

[0025] Before cracking, the walnuts are sorted into three or more grades, namely large, medium and small, by diameter or weight using a sieve machine. Then, walnuts of the same grade are poured into the feed inlet 3 in batches to avoid walnuts with large size differences being cracked together, which would cause some walnuts to be over-pressurized and ultimately cause the walnut kernels inside to be broken too severely.

[0026] As a preferred technical solution in this embodiment, such as Figure 3 As shown, the shape of the outer surface of the pressure-sensing conical shell-breaking plate 14 corresponds to the shape of the inner wall of the inverted conical walnut placement groove 15 located on the upper surface of the electronic weighing shell-breaking platform 9. Multiple pressure sensors are installed inside the pressure-sensing conical shell-breaking plate 14. The detection probe of the pressure sensor is located on the lower surface of the pressure-sensing conical shell-breaking plate 14, and a weighing sensor is installed inside the electronic weighing shell-breaking platform 9. Before using the equipment, the amount of walnuts to be processed at one time is entered on the control panel 2.

[0027] The walnuts poured into the feeding port 3 will enter the inverted cone-shaped walnut placement slot 15 located on the upper surface of the electronic weighing shelling platform 9 along the rolling trough. When the weighing sensor installed inside the electronic weighing shelling platform 9 detects that the walnuts have reached the corresponding proportion, the cutting cylinder 4 pushes the cutting plate 5 to block the rolling trough and prevent the walnuts from continuing to enter the electronic weighing shelling platform 9.

[0028] The inner wall of the square slot 12 has a square cross-section. The outer surface of the square rotating shaft 13 is in contact with the inner wall of the square slot 12, and the square rotating shaft 13 and the square slot 12 are slidably connected. On both sides below the electronic weighing shell-breaking platform 9, there is a vibrator 8 fixedly installed inside the shell-breaking machine housing 1, and the upper end face of the vibrator 8 is in contact with the lower end face of the electronic weighing shell-breaking platform 9. When the material cutting cylinder 4 is started, the vibrator 8 is started, causing the electronic weighing shell-breaking platform 9 to vibrate. By vibrating the electronic weighing shell-breaking platform 9, the walnuts piled up inside the inverted conical walnut placement trough 15 can be broken up and spread flat inside the inverted conical walnut placement trough 15.

[0029] After the vibrator 8 has run for half a minute, turn off the vibrator 8 and start the drive motor 10. The drive motor 10 can drive the square rotating shaft 13 connected to it to rotate. Since the outer surface of the square rotating shaft 13 is in contact with the inner wall of the square slot 12 located on the upper end face of the threaded rod 11, when the square rotating shaft 13 rotates, the threaded rod 11 will rotate along with it. Through the threaded structure between the threaded rod 11 and the shell-breaking machine housing 1, the rotating threaded rod 11 will move up and down while rotating. At this time, move the threaded rod 11 downward. When moving the threaded rod 11 downward, ensure that... Its descent speed is one centimeter every five seconds. As the threaded rod 11 rotates and moves downward, the pressure-sensing conical shell-breaking plate 14 fixed to its lower end face will also rotate and move downward. As the pressure-sensing conical shell-breaking plate 14 descends, it will contact the walnut and slowly apply a soft squeezing force to it. In the process of applying downward pressure to the walnut through the pressure-sensing conical shell-breaking plate 14, the walnut will rotate along with the rotation of the pressure-sensing conical shell-breaking plate 14, thereby applying rotational shear force to it.

[0030] In this embodiment, as the walnut shell slowly rotates and is pressed down by the pressure-sensing conical shell-breaking plate 14, cracks will gradually appear in the shell and gradually expand until it completely breaks open. This avoids the high-energy impact caused by the instantaneous collapse of the walnut shell being transmitted to the kernel, which would ultimately cause serious damage to the kernel.

[0031] As a preferred technical solution in this embodiment, such as Figure 3As shown, a screen conveyor belt 7 is provided below the electronic weighing shell-breaking platform 9, and a walnut shell collection cart 6 is provided below the screen conveyor belt 7. When a sudden drop in resistance is detected by the pressure sensor installed inside the pressure-sensing conical shell-breaking plate 14, indicating that the walnut shell has been broken, the drive motor 10 drives the square rotating shaft 13 in the opposite direction to rotate and move the pressure-sensing conical shell-breaking plate 14 upward. During the upward movement of the pressure-sensing conical shell-breaking plate 14, the discharge valve 16 and the vibrator 8 are opened. The vibration generated by the vibrator 8 will cause the broken walnuts located inside the inverted conical walnut placement groove 15 to fall through the discharge valve 16 to the upper surface of the walnut shell collection cart 6 for sorting and screening.

[0032] Once the weighing sensor inside the electronic weighing and shell-breaking platform 9 detects that all the walnuts inside the inverted conical walnut placement trough 15 have disappeared, the discharge valve 16 is closed, and the cutting plate 5 is pulled upward by the cutting cylinder 4. The above operation can be repeated.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
