Description

Technical Field

[0001] This utility model relates to the field of rapeseed processing technology, and in particular to an automatic unloading mechanism for rapeseed oil pressing cake. Background Technology

[0002] Rapeseed oil residue, also known as rapeseed cake, is a byproduct of rapeseed oil extraction. After pressing, the rapeseed cake forms thin sheets. In order to reduce storage and transportation space, the rapeseed cake needs to be extruded and shaped.

[0003] A search revealed a prior art device for rapid collection of pressed rapeseed oil residue (Publication No.: CN214563231U), comprising a crushing box, a feeding box fixedly connected to the lower end of the crushing box, equidistantly distributed legs fixedly connected to the lower end of the feeding box, a base plate fixedly connected to the lower end of the legs, a housing fixedly connected to the right end of the crushing box, a drive motor fixedly connected inside the housing, equidistantly distributed through holes on the right end of the crushing box, a transmission rod fixedly connected to the left end of the drive motor, a first spur gear fixedly connected to the outside of the transmission rod, and a bearing fixedly connected to the right end of the crushing box. This device provides a rapid collection of pressed rapeseed oil residue.

[0004] Existing technology mainly involves crushing rapeseed cake with a crushing roller. The powder falls under gravity and is then fed into a forming box through a collection trough and squeezed into blocks. After being crushed, rapeseed cake has a certain oiliness and is easy to stick. Relying on gravity to feed the material can easily cause it to clump and block at the feed inlet of the crushing box, making it difficult to ensure continuous and stable feeding. There is room for optimization.

[0005] Therefore, we propose an automatic unloading mechanism for rapeseed oil press cake. Utility Model Content

[0006] The present invention mainly solves the technical problem of rapeseed cake powder easily clumping and blocking material, and provides an automatic unloading mechanism for rapeseed oil pressing cake.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: an automatic unloading mechanism for rapeseed oil press cake, comprising:

The crossbar is fixedly connected to the crushing box, and the push plate is elastically set on the crossbar. A drive motor can push the crossbar to move and push the material falling from the crushing box.

[0010] In a preferred embodiment of this utility model, the crushing box is funnel-shaped, and a slot for material to fall is provided between the crushing box and the conveying box.

[0011] In a preferred embodiment of this utility model, the crushing box is provided with two reversibly rotating crushing rollers, and the ends of the two crushing rollers are fixedly installed with meshing gears.

[0026] An automatic unloading mechanism for rapeseed oil press cake, such as Figure 1 and Figure 2 As shown, it includes:

[0027] A base is provided, and a crushing box 10 and a conveying box 11 are fixedly installed on the top of the base. The crushing box 10 is equipped with crushing rollers, and an auger 12 is rotatably installed in the conveying box 11. The auger 12 can discharge the crushed material to one side. The crushing box 10 is funnel-shaped. A groove for material to fall is opened between the crushing box 10 and the conveying box 11. Two counter-rotating crushing rollers are provided in the crushing box 10. The ends of the two crushing rollers are fixedly installed with meshing gears. A motor is fixedly installed on the outside of the crushing box 10. The output shaft of the motor is fixedly connected to one of the crushing rollers. The inside of the conveying box 11 is provided with a circular chamber. The auger 12 is rotatably installed in the chamber. A drive motor 13 is fixedly installed on the outside of the conveying box 11. The output shaft of the drive motor 13 is fixedly connected to the auger 12.

[0028] In this scheme, the rapeseed cake fed into the crushing box 10 is crushed by two crushing rollers driven by a motor to rotate in opposite directions, so as to facilitate the subsequent extrusion into blocks. The crushed rapeseed cake falls from the crushing box 10 into the conveying box 11. The drive motor 13 drives the auger 12 to rotate and push the powder radially along the conveying box 11. A forming box is provided on one side of the conveying box 11. The forming box is equipped with a push rod. The output shaft of the push rod is fixedly installed with an extrusion block. A connecting pipe is provided at the end of the conveying box 11. The connecting pipe extends into the forming box. The crushed material is fed into the forming box by the auger 12, which facilitates continuous automatic feeding during the shaping stage. At the same time, the crushing box 10, the conveying box 11 and the forming box are connected, which can reduce the dust escape during the powder conveying process.

[0029] like Figure 3 , Figure 4 and Figure 5 As shown, the anti-blocking structure is set between the crushing box 10 and the conveying box 11 to strike the falling material. The anti-blocking structure includes a crossbar 20 and a push plate 21. The crossbar 20 is fixedly connected to the crushing box 10. The push plate 21 is elastically set on the crossbar 20. The drive motor 13 can push the crossbar 20 to move and push the material falling from the crushing box 10. The crossbar 20 is a rectangular bar. The crossbar 20 is fixedly installed on the inner wall of the crushing box 10 and located above the slot. The push plate 21 is a rectangular plate. The push plate 21 extends downward into the pitch of the auger 12. The anti-blocking structure also includes a stop bar 22. A stop bar 22 is set on each side of the push plate 21. The push plate 21 can push the stop bar 22 to deform. The push plate 21 has a through slot adapted to the crossbar 20. The push plate 21 can slide along the crossbar 20. The stop bar 22 forms an L-shaped bar. The two stop bars 22 extend to the two side walls of the push plate 21 respectively.

[0030] In this scheme, since the powder falling from the crushing box 10 into the conveying box 11 is gravity-fed, and the crushed rapeseed cake is prone to sticking, the rotating auger 12 pushes the push plate 21 to slide along the crossbar 20. The push plate 21 can intermittently hit the baffles 22 on both sides to generate vibration, thereby promoting the discharge of powder at the slot between the crushing box 10 and the conveying box 11. At the same time, the horizontal movement of the push plate 21 can suppress the powder from clumping at the slot and causing blockage. It has the characteristics of stable discharge and not easy to block.

[0031] The working principle of this utility model is as follows: The rapeseed cake fed into the crushing box 10 is crushed by two crushing rollers driven by a motor to rotate in opposite directions, so as to facilitate the later extrusion into blocks. After crushing, the rapeseed cake falls from the crushing box 10 into the conveying box 11. The drive motor 13 drives the auger 12 to rotate and push the powder radially along the conveying box 11. A forming box is provided on one side of the conveying box 11. A push rod is provided on the forming box. An extrusion block is fixedly installed on the output shaft of the push rod. A connecting pipe is provided at the end of the conveying box 11. The connecting pipe extends into the forming box. The crushed powder is fed into the forming box and forms a dense block structure after being pressed by the extrusion block.

[0032] The rotating auger 12 pushes the push plate 21 to slide along the crossbar 20. The push plate 21 can intermittently strike the baffles 22 on both sides to generate vibration, thereby promoting the discharge of powder at the slot between the crushing box 10 and the conveying box 11. At the same time, the horizontal movement of the push plate 21 can suppress the powder from clumping at the slot and causing blockage, thus achieving continuous and stable feeding.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
