Description

Technical Field

[0001] This utility model relates to the technical field of walnut processing equipment, and in particular to a walnut shell-breaking device that uses a crank-rocker mechanism to drive a percussionist to reciprocate. Background Technology

[0002] Walnut kernels have small gaps between them, making it difficult to crack and remove the kernels. Traditional physical shelling methods, such as using pliers or hammers, cannot meet the needs of mass production and industrial processing. Existing shelling machines suffer from drawbacks such as high processing costs, complex procedures, uneven extrusion, inconvenience for small workshops and home use, and low kernel yield. To improve nut processing efficiency and product quality, a hammering-type walnut shelling machine has been designed. Summary of the Invention

[0008] Compared with the prior art, this utility model has the following advantages and effects:

[0009] (1) The walnut shelling tool described in this utility model has a simple structure, low manufacturing cost, is easy to operate, easy to load and unload, and has a reasonable overall structural design.

[0010] (2) The connecting parts in the knocking walnut shelling machine of this utility model are standard parts and have good interchangeability.

[0011] (3) The walnut shelling machine described in this utility model can perform one-to-one walnut shelling, with a high yield and complete appearance of the walnuts, and is suitable for small workshops and family use.

[0012] (4) The material distribution device described in this utility model can handle different varieties and sizes of walnuts by changing the size of the material distribution plate hole, thus realizing the purpose of the device to process different kinds of walnuts and making the device more applicable.

[0013] (5) The material distribution device described in this utility model can sweep the walnuts and walnut shells after they have been cracked into the material distribution plate by rotating itself, so that it will not affect the subsequent cracking work. When a large number of walnuts enter the feeding port, by controlling the size of the feeding port, the walnuts fall into the material distribution plate in sequence and are embedded in the holes of the material distribution plate, which can improve the orderliness of the use of the device.

[0014] (6) The material distribution device and the shell breaking device described in this utility model achieve a linkage effect: the active shaft rotates once, and the shell breaking device performs a linear reciprocating motion once to complete one shell breaking. At the same time, the active shaft drives the driven shaft to rotate once synchronously, and transmits torque to the transmission head through the shaft head. The shaft head and the transmission shaft adopt a grooved wheel intermittent motion mechanism. The shaft head rotates once, causing the transmission shaft to rotate 45°, causing the material distribution plate to rotate 45°. The limiting block overcomes the rotational inertia and stops at the next hole position to break the shell, which can effectively improve the shell breaking accuracy.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0026] To make the technical means, creative features, achieved objectives, and effects of this invention easier to understand, the specific embodiments of this utility model are described below with reference to the accompanying drawings. The specific embodiments described herein are limited to illustration and explanation of this utility model and are not intended to limit it. The specific working principle and usage method of this utility model are as follows:

[0027] After the walnuts are poured into the hopper 12 on the upper left of the frame, they fall sequentially into the corresponding holes of the distribution plate 41. The motor 21 is then started. The output of the motor 21 drives the reducer 22 to rotate. The power of the reducer 22 is transmitted to the drive shaft 23 via the first transmission chain 23, driving it to rotate. The second transmission chain 24 connects the drive shaft and the driven shaft 26, ensuring that they rotate synchronously.

[0028] The rotation of the drive shaft 23 drives the shell-breaking eccentric shaft 33 to rotate. The shell-breaking eccentric shaft 33 is connected to the shell-breaking plate 31, and the shell-breaking rod 32 is installed on the shell-breaking plate 31. As the eccentric shaft 33 rotates, the shell-breaking rod 32 knocks on the walnuts that continuously fall from the hopper 12 into the distribution plate 41, causing the walnut shells to crack and separating the walnut kernels from the shells.

[0029] The walnuts fall onto the distribution plate 41 below the hopper 12. The driven shaft 26 transmits torque to the shaft head 42, causing the shaft head 42 to collide and rotate the transmission head 43. The disc shaft 44 connects the distribution plate 41 and the transmission head 43; the rotation of the transmission shaft causes the distribution plate 41 to rotate together. The distribution plate 41 has eight holes corresponding to the eight prisms of the transmission head 43. Through the rotation of the disc shaft 44 and the engagement of the limiting block 45, intermittent motion is achieved, ensuring the synchronous execution of the knocking and material-changing actions. The finished walnuts, having completed their shelling, are swept into the recycling bin 16 directly below as the distribution plate rotates, thus achieving synchronous operation of knocking, material changing, and collection, completing the shelling process.

[0030] After the entire process is complete, turn off the motor power to stop the equipment. Then, clean the walnut shells from the recycling bin and inspect and maintain all components to ensure the equipment continues to operate normally and extend its lifespan.

[0031] The above technical features constitute the preferred embodiment of this utility model, which has strong adaptability and the best implementation effect. Unnecessary technical features can be added or removed according to actual needs to meet the needs of different situations.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
