Description

Technical Field

[0001] The invention relates to the field of peanut-shelling auxiliary tools, in particular to an automatic peanut-shelling robot. Background Art

[0002] Peanuts, originally known as groundnuts, are a type of nut that is abundant in my country. Peanut fruits contain protein, fat, carbohydrates, vitamins A, B6, E, and K, as well as minerals such as calcium, phosphorus, and iron. Therefore, peanuts are often consumed in our daily lives. Peanuts are also the main crop for producing peanut oil. After harvest, peanuts need to be shelled before they can be used in food production and oil extraction.

[0003] The traditional method of shelling peanuts is manual shelling. It does not take much effort to shell peanuts, but it hurts the hands and takes a long time, which is labor-intensive and inefficient. Although there are automatic peanut shelling devices on the market, in actual use, these devices will crush the peanut shells when shelling peanuts. The surface of dry peanut shells has a lot of dust, and when they are crushed, a large amount of dust is easily generated. This dust not only affects the surrounding environment, but also falls into the peanuts, making subsequent separation more troublesome. Therefore, how to solve this problem needs to be considered. Summary of the Invention

When in use, the peanut peeling robot utilizes automatic shelling processing to improve the actual processing efficiency.

[0029] As an embodiment of the present invention, it also includes a dust removal mechanism, which is used to remove dust generated by peeling peanuts. The dust removal mechanism includes a water tank 5 fixedly connected to the left side of the base 1. The water tank 5 is filled with water. The inner bottom space of the water tank 5 is connected to a dust extraction pipe 30. The other end of the dust extraction pipe 30 extends to the lower left of the rotating roller 23. A water inlet 11 is installed at the inner top of the water tank 5, and a drain outlet 20 is installed at the inner bottom of the water tank 5. Manual valves are installed inside the water inlet 11 and the drain outlet 20. In specific use, the two manual valves are used to seal the inside of the water inlet 11 and the drain outlet 20.

[0030] As an embodiment of the present invention, it also includes a driving mechanism, which cooperates with the dust removal mechanism. The driving mechanism includes a mounting frame 31 installed on the rear side of the shell 2, and a driving motor 15 is installed on the mounting frame 31. The output shaft of the driving motor 15 extends to the interior of the shell 2 and is fixedly connected to the rear end of the rotating roller 23. The driving mechanism includes a mounting frame 31 installed on the rear side of the shell 2, and a driving motor 15 is installed on the mounting frame 31. The output shaft of the driving motor 15 extends to the interior of the shell 2 and is fixedly connected to the rear end of the rotating roller 23. When the driving motor 15 is started, the rotating roller 23 is rotated, thereby realizing In the current peanut shelling operation, the drive motor 15 adopts a servo motor. The servo motor can control the speed and has very accurate position accuracy. It can convert the voltage signal into torque and speed to drive the control object. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an actuator and has the characteristics of small electromechanical time constant and high linearity. It can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft. It is divided into two categories: DC and AC servo motors. Its main feature is that there is no self-rotation when the signal voltage is zero, and the speed decreases uniformly with the increase of torque;

[0031] As an embodiment of the present invention, the spaces on opposite sides of the two piston cylinders 6 are both connected to a first one-way tube 7, and the other ends of the two first one-way tubes 7 are commonly connected to a first connecting tube 8, and the other end of the first connecting tube 8 is connected to the inner top space of the water tank 5;

[0032] As an embodiment of the present invention, it also includes an air separation mechanism, which is used to remove the debris generated by crushing peanuts. The air separation mechanism includes a hollow bar 27 fixedly connected to the right inner wall of the base 1, and a plurality of air holes 28 are opened on the left inner wall of the hollow bar 27. The opposite side spaces of the two piston cylinders 6 are connected with a second one-way tube 9, and the other ends of the two second one-way tubes 9 are commonly connected with a second connecting tube 10. The other end of the second connecting tube 10 is connected with the interior of the hollow bar 27. A one-way valve is installed inside each first one-way tube 7 and the second one-way tube 9. The one-way valve inside the first one-way tube 7 flows in a one-way direction from the first connecting tube 8 to the corresponding piston cylinder 6, and the one-way valve inside the second one-way tube 9 flows in a one-way direction from the two piston cylinders 6 to the second connecting tube 10. An inclined guide plate 21 is fixedly connected between the front and rear inner walls of the shell 2, a vertical partition 29 is fixedly connected to the inner bottom of the base 1, and two sealing doors 4 are installed on the front side of the base 1.

[0033] In the present invention, in actual use, peanuts to be shelled are fed from the feed port 3, and then the drive motor 15 is started. The start of the drive motor 15 causes the rotating roller 23 to rotate. The rotation of the rotating roller 23 enables the first crushing teeth 24 and the second crushing teeth 25 to cooperate to shell the peanuts. The shelled peanuts fall into the base 1 through the inclined guide plate 21.

[0034] During the above process, the rotation of the rotating roller 23 causes the incomplete gear 12 to rotate, and the rotation of the incomplete gear 12 continuously and intermittently meshes with the two racks 13. When the incomplete gear 12 meshes with the upper rack 13, it drives the upper rack 13 to move left. When the incomplete gear 12 meshes with the lower rack 13, it causes the lower rack 13 to move right. In this way, the whole composed of the two racks 13 and the two connecting bars 14 can be made to reciprocate left and right. Using the two fixing rods 17, the two piston plates 16 can be made to reciprocate left and right.

[0035] In conjunction with the one-way valves inside the first connecting pipe 8 and the second connecting pipe 10, a one-way gas flow can be generated in the inner top space of the water tank 5, the two piston cylinders 6, the second connecting pipe 10 and the hollow bar 27. The gas flow is discharged from the blast hole 28 to air-select the shelled peanuts, blowing small peanut shells to the space on the left side of the vertical partition 29, while the peanuts and larger peanut shells fall to the space on the right side of the partition 29, facilitating subsequent cleaning operations;

[0036] In addition, since the gas in the top space of the water tank 5 is extracted, a negative pressure is generated at the top of the water tank 5, and the dust generated during dust collection is sucked into the inner bottom of the water tank 5 by the dust extraction pipe 30 for dust removal and dust collection, thereby avoiding the spread of dust and eliminating the need for subsequent separate separation of the dust, thereby improving the overall efficiency.

[0037] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can, for example, be implemented in an order other than those illustrated or described herein.
