[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment 1

[0025] As Figure 1 - Figure 3As shown in the figure, a nut shelling and screening machine includes a machine body 1 and a feed hopper 11. At the bottom of the machine body 1, there are a shell outlet 12, a whole fruit outlet 13, and a broken fruit outlet 14. An observation window 16 is provided on the machine body 1, and the observation window 16 is made of transparent glass. Control keys 15 are provided on the machine body 1. A rotating assembly is fixedly installed at the top of the machine body 1, and an electric push rod 2 is connected to the rotating assembly. The top of the electric push rod 2 is fixedly connected to a storage box 21, and the storage box 21 is located above the feed hopper 11. A first motor 22 is fixedly installed in the storage box 21. The output end of the first motor 22 is fixedly connected to a first lead screw 221. A first threaded ring 222 is threadedly connected to the first lead screw 221. A extension rod 223 is fixedly connected to the first threaded ring 222. A strip-shaped groove 211 is provided at the bottom end of the first lead screw 221, and one end of the extension rod 223 passes through the inside of the strip-shaped groove 211 and is slidably connected to the strip-shaped groove 211. A push fork 224 is fixedly connected to one end of the extension rod 223. When the nut shelling and screening machine is working, it mainly involves three parts: a feeding system, a shelling system, and a separation system. First, nuts are put into the feed hopper 11 and sent into the inside of the shelling machine through the feed hopper 11. A roller is installed inside the shelling machine, and the nuts will be subjected to a certain amount of extrusion and friction. By using the rotation and friction of the roller, the nut shell and the kernel are separated. Finally, through air separation, the kernels and the shells are sent to different discharge ports respectively to achieve their complete separation. However, due to the hardness, humidity, and shape of the nuts, the nuts may accumulate at the feed hopper 11 during shelling, affecting the normal flow of the nuts in the feed hopper 11. Workers still need to manually dredge it regularly, which not only results in low efficiency of nut shelling and screening but also poses certain safety hazards. When preventing the nuts accumulated in the feed hopper 11 from blocking, a push fork 224 is installed to prevent the nuts accumulated in the feed hopper 11 from blocking. First, start the micro motor 24 through the control device. The micro motor 24 will drive the electric push rod 2 to rotate through the gear set, so that the storage box 21 moves to the upper part of the feed hopper 11. Then start the electric push rod 2 to contract. The electric push rod 2 will drive the storage box 21 to descend, so that the push fork 224 penetrates into the nuts in the feed hopper 11. Then start the first motor 22 to rotate. The first motor 22 drives the first threaded ring 222 to rotate through the first lead screw 221. The first threaded ring 222 drives the push fork 224 to move in the nut pile through the extension rod 223 to dredge and loosen the nut pile, avoiding the problem of blockage of the feed hopper 11 caused by nut jamming, and ensuring the continuous and efficient production efficiency of the nut shelling and screening machine.

[0026] Further, the rotating assembly includes a micro motor 24, a main gear 241, a linkage shaft 25 and a driven gear 251. The micro motor 24 is fixedly installed inside the placement box 23. The main gear 241 is fixedly connected to the output end of the micro motor 24. The linkage shaft 25 is movably installed inside the placement box 23, and one end of the linkage shaft 25 penetrates out of the inside of the placement box 23 and is fixedly connected to the bottom end of the electric push rod 2. The driven gear 251 is fixedly installed on the linkage shaft 25, and the driven gear 251 is meshed with the main gear 241. By starting the micro motor 24 through the control key 15 to drive the main gear 241 to rotate, the main gear 241 will synchronously drive the meshed driven gear 251 to rotate when rotating. The driven gear 251 drives the electric push rod 2 to rotate through the linkage shaft 25, so that the storage box 21 on the electric push rod 2 is moved out of the feed hopper 11.

A shock absorption device is provided at the bottom end of the storage base 3. The shock absorption device includes a spring 35, a buffer base 351 and a damper 352. The spring 35 is fixedly installed at the four corners of the bottom end of the storage base 3. The buffer base 351 is fixedly installed at one end of the spring 35 in contact with the ground. A damper 352 is fixedly installed on the buffer base 351, and one end of the damper 352 penetrates out of the inside of the spring 35 and is fixedly connected to the bottom end of the storage base 3. When increasing the stability and reliability of the nut shelling and screening machine, the stability and reliability of the nut shelling and screening machine are increased by installing the universal wheel 321 and the spring 35. When it is necessary to move the machine body 1 device, first start the second motor 331 through the control key 15. The second motor 331 will drive the support frame 32 to move out of the groove 31 through the second lead screw 332 and the connecting rod 334, so that the universal wheel 321 is in contact with the ground. The machine body 1 is moved through the universal wheel 321. After moving to the designated position, the universal wheel 321 retracts, and the buffer base 351 contacts the ground. The vibration generated during the operation of the nut shelling and screening machine will be absorbed by the spring 35 and the damper 352, preventing the displacement of the machine body 1 caused by vibration during the shelling process, significantly improving the stability of the nut shelling and screening machine. The seamless transformation from the movement of the nut shelling and screening machine to stable operation is realized through the coordinated cooperation of the universal wheel 321 and the spring 35.

[0029] Further, a sliding groove 34 is provided on the inner wall of the groove 31. A slider 341 is slidably installed in the sliding groove 34, and the other end of the slider 341 is fixedly connected to one side of the support frame 32. The slider 341 and the sliding groove 34 are used to stabilize the support frame 32, so that the support frame 32 moves stably in the groove 31.

[0030] Working principle: When using this nut shelling and screening machine, first, to prevent the nuts piled up in the feeding hopper 11 from getting blocked, the pushing fork 224 is installed to prevent the nuts piled up in the feeding hopper 11 from getting blocked. First, start the micro motor 24 through the control device. The micro motor 24 will drive the electric push rod 2 to rotate through the gear set, so that the storage box 21 moves above the feeding hopper 11. Then start the contraction of the electric push rod 2. The electric push rod 2 will drive the storage box 21 to descend, so that the pushing fork 224 penetrates into the nuts in the feeding hopper 11. Then start the rotation of the first motor 22. The first motor 22 drives the first threaded ring 222 to rotate through the first lead screw 221. The first threaded ring 222 drives the pushing fork 224 to move in the nut pile through the extension rod 223 to dredge and loosen the nut pile, avoiding the problem of the feeding hopper 11 being blocked due to nut jamming, and ensuring the continuous and efficient production efficiency of the nut shelling and screening machine.

[0031] Finally, when increasing the stability and reliability of the nut shelling and screening machine, the stability and reliability of the nut shelling and screening machine are increased by installing universal wheels 321 and springs 35. When the machine body 1 device needs to be moved, first start the second motor 331 through the control key 15. The second motor 331 will drive the support frame 32 to move out of the groove 31 through the second lead screw 332 and the connecting rod 334, so that the universal wheels 321 contact the ground. Move the machine body 1 through the universal wheels 321. After moving to the designated position, the universal wheels 321 contract, and the buffer base 351 contacts the ground. The vibration generated during the operation of the nut shelling and screening machine will be absorbed by the spring 35 and the damper 352, preventing the displacement of the machine body 1 caused by vibration during the shelling process, significantly improving the stability of the nut shelling and screening machine. Through the coordinated cooperation of the universal wheels 321 and the spring 35, a seamless transition from the movement of the nut shelling and screening machine to stable operation is achieved.
