[0002] The seeds of oil crops contain a large amount of fat, which can be extracted for consumption or as industrial and pharmaceutical raw materials. In the oil pressing process, large pieces of block oil pressing powder cakes generally need to be transferred, mixed, and transported. In the prior art, the transfer, mixing, and transportation are generally a screw conveying device, that is, a screw rod is used to disperse, mix, and transport a variety of different large block oil pressing powder cakes, that is, it does not have a structure for pre-cutting large block oil pressing powder cakes. However, for large block oil pressing powder cakes, they are directly transported to the feed hopper, and their volume is large, which can easily lead to blockage of the feed hopper. Moreover, multiple large block oil pressing powder cakes are piled up together in the feed hopper. Dispersing and mixing only by a screw rod may also easily result in uneven material mixing, or a longer screw rod is required to achieve better material dispersion and mixing effects, but the equipment will occupy a larger area.

The connecting seat is fixedly connected to all the nut seats and is located above the conveying assembly. A slitting assembly is provided on the connecting seat at the top of each conveying assembly.

[0007] As a further optimization scheme of the utility model, the slitting assembly includes a fixed seat rotatably connected to the connecting seat, a plurality of slitting pieces arranged at the bottom of the fixed seat and having a pointed bottom, and a driving piece driving the fixed seat to rotate.

[0008] As a further optimization scheme of the utility model, the mixing and conveying assembly includes an outer shell, a support seat arranged at the discharge port end of the outer shell, a spiral conveying rod rotatably connected to the support seat and the outer shell and used for mixing and conveying materials, a driving member for driving the spiral conveying rod to rotate, and a feed hopper arranged at the top of the outer shell and away from the discharge port end of the outer shell.

[0009] As a further optimization solution of the utility model, a scraper plate is provided on the inner wall of the feed hopper.

[0010] As a further optimization scheme of the utility model, the conveying assembly includes a conveyor belt body and a protective shell, the upper end surface of the protective shell is higher than the upper end surface of the block powder cake on the top of the conveyor belt body, and the bottom of the conveyor belt body is in contact with the top of the scraper plate.

[0011] As a further optimization solution of the utility model, the synchronous drive assembly includes a driving member 2 connected to one of the screw rods and a synchronous member for driving all the support frames to rotate synchronously.

[0012] The beneficial effects of the utility model are:

[0013] 1) The utility model can reduce the problem of large block powder cakes clogging the feed hopper by pre-cutting and crushing the large block powder cakes into small pieces and then conveying them to the inside of the outer shell, and also facilitate the subsequent full mixing of multiple materials inside the outer shell, that is, reducing the pressure of the spiral conveying rod to disperse the large block powder cakes and speeding up the speed of the spiral conveying rod to disperse the large block powder cakes;

[0014] 2) The utility model can drive the cutting components on the top of each conveying component to move downward together by moving the connecting seat downward, and can simultaneously cut and crush a variety of large block powder cakes into small pieces, which is highly efficient, occupies a small area, and is easy to use.

[0020] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] like Figure 1-4 As shown, a mixing and feeding device for oil-pressing powder cakes comprises a mixing and conveying component 1, a plurality of conveying components 2 radially arranged at the top of the feeding end of the mixing and conveying component 1, and a pre-cutting component 3 for cutting the block powder cakes after the small-pressing process;

[0022] The pre-cutting component 3 includes a connecting seat 7, a plurality of support frames 4, a screw rod 5 rotatably connected to the support frame 4, a nut seat 6 connected to the screw rod 5 via a ball nut pair, and a synchronous driving component for driving all the support frames 4 to rotate synchronously. The connecting seat 7 is fixedly connected to all the nut seats 6 and the connecting seat 7 is located above the conveying component 2. A slitting component is provided on the connecting seat 7 at the top of each conveying component 2.

[0023] Furthermore, the slitting assembly includes a fixed seat 10 rotatably connected to the connecting seat 7, a plurality of slitting pieces 11 arranged at the bottom of the fixed seat 10 and having a pointed bottom, and a driving piece 3 12 driving the fixed seat 10 to rotate. During the descent of the connecting seat 7, the slitting piece 11 will gradually be inserted into the interior of the block powder, and then the driving piece 3 12 will drive the fixed seat 10 and the slitting piece 11 to rotate, and the slitting piece 11 can cut and smash the block powder into small pieces, and then pass through the conveyor belt body 20. 1, so that the cut small pieces of material fall into the feed hopper 105. The utility model can reduce the problem of large pieces of blocky powder cakes clogging the feed hopper 105 by pre-cutting and crushing the large pieces of blocky powder cakes into small pieces and then conveying them to the inside of the outer shell 101, and it is also easy to fully mix various materials in the outer shell 101 later, that is, the pressure of the spiral conveying rod 103 to disperse the large pieces of blocky powder cakes is reduced, and the speed of the spiral conveying rod 103 to disperse the large pieces of blocky powder cakes is accelerated.

[0024] It should be noted that, in this embodiment, the cutting piece 11 is any one of a cutting rod and a cutting plate;

[0025] In this embodiment, the driving member 3 12 drives the fixed seat 10 and the cutting member 11 to rotate, which not only allows the cutting member 11 inserted into the large block powder to twist and cut the large block powder into small pieces, but also the rotation of the cutting member 11 has a crushing effect, which makes it easy to cut and crush the large block powder into small pieces, and is very convenient to use.

[0026] Preferably, the mixing and conveying assembly 1 comprises an outer shell 101, a support seat 102 disposed at the discharge port end of the outer shell 101, a spiral conveying rod 103 rotatably connected to the support seat 102 and the outer shell 101 and used for mixing and conveying materials, a driving member 104 for driving the spiral conveying rod 103 to rotate, and a feed hopper 105 disposed at the top of the outer shell 101 and away from the discharge port end of the outer shell 101;

[0027] After the material is cut into small pieces, it can be transported to the inside of the outer shell 101 through the feed hopper 105, and then the driving member 104 will drive the spiral conveying rod 103 to rotate. Due to the rotation of the spiral conveying rod 103, it can disperse the material, mix it with other materials, and transport it out from the discharge port end of the outer shell 101, thereby completing the mixed transportation of multiple materials.

[0028] Furthermore, a scraper plate 13 is provided on the inner wall of the feed hopper 105 .

[0029] Furthermore, the conveying component 2 includes a conveyor belt body 201 and a protective shell 202. The upper end surface of the protective shell 202 is higher than the upper end surface of the block powder cake on the top of the conveyor belt body 201, which can play a protective role. When cutting the block powder cake, it can reduce or avoid the leakage of materials from the side of the conveyor belt body 201. The bottom of the conveyor belt body 201 is in contact with the top of the scraper plate 13, which is used to scrape off the material adhered to the bottom of 20. The scraped material will be transported to the inside of the outer shell 101 through the feed hopper 105, and then dispersed and mixed with other materials through the rotation of the spiral conveying rod 103 and transported out from the discharge port end of the outer shell 101.

[0030] Preferably, the synchronous drive assembly includes a driving member 9 connected to one of the screw rods 5 and a synchronous member 8 for driving all the support frames 4 to rotate synchronously;

[0031] In this embodiment, the synchronous member 8 comprises a synchronous wheel sleeved on each of the screw rods 5, and a synchronous belt is arranged between each two synchronous wheels, that is, Figure 2As shown, when it is in use, one of the screw rods 5 is driven to rotate through the driving member 2 9, and the synchronous wheel on the screw rod 5 will rotate with the screw rod 5. Through the action of the synchronous belt and synchronous wheel, all the screw rods 5 are driven to rotate together, thereby realizing the rising or falling of the connecting seat 7.

[0032] It should be noted that, in this embodiment, the driving element 1 104, the driving element 2 9, and the driving element 3 12 are all servo motors.

[0033] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
