[0002] Rapeseed, also known as Brassica rapa, is a herbaceous cruciferous crop and one of the main oil crops and nectar crops in my country. Its seeds are one of the main varieties of raw materials for making oils and fats. Rapeseed oil, commonly known as rapeseed oil, is a transparent or translucent liquid obtained by squeezing rapeseed, the seed of the cruciferous plant Brassica rapa (i.e. rapeseed). It is generally dark yellow or brown. The preparation process of rapeseed oil is to first remove impurities and dry the rapeseed, then crush it and roll it, then steam and fry it, and finally put it into the oil press to extract rapeseed oil at low temperature. The crushing of rapeseed in this process is related to the effect of subsequent steaming and frying and the amount of oil pressed, so it is very important.

[0003] For example, the application number is CN201921678783.3. The utility model provides a rapeseed grain crushing mechanical device.

[0023] refer to Figure 2 The protective support assembly 7 includes a protective cover 71, which is sleeved on the surface of the electric telescopic rod 5. The top of the inner wall of the protective cover 71 is fixedly connected to the top of the electric telescopic rod 5. The top of the surface of the protective cover 71 is fixedly connected to a support rod 72. Three support rods 72 are arranged and distributed in a circular shape with equal distances. The outer side of the support rod 72 is fixedly connected to the inner wall of the discharge hopper 3.

[0024] As a technical optimization solution of the utility model, by setting up a protective support assembly 7, the user can use the protective cover 71 to protect the electric telescopic rod 5 during the use of the electric telescopic rod 5 to prevent rapeseed fragments from hitting the surface of the electric telescopic rod 5 for a long time and causing damage to the electric telescopic rod 5. The support rod 72 can then be used to support the electric telescopic rod 5 in the air to ensure stability in use.

[0025] refer to Figure 2 The cleaning assembly 8 includes a support seat 81, the top of the support seat 81 is fixedly connected to both sides of the bottom of the discharge hopper 3, the interior of the support seat 81 is slidably connected with a nozzle 82, and the outer side of the nozzle 82 is connected to the air source through a conduit.

[0026] As a technical optimization scheme of the utility model, by setting up a cleaning component 8, when a large amount of rapeseed debris is attached to the surface of the cleaning head 6 and needs to be cleaned, the user can first start the electric telescopic rod 5 to drive the cleaning head 6 to move downward to the bottom of the discharge head, and then the user can take out the nozzle 82 from the support seat 81, point the jet end of the nozzle 82 toward the surface of the cleaning head 6, and then use the air flow of the air source to spray through the nozzle 82, so as to spray off the rapeseed debris on both sides attached to the surface of the cleaning head 6.

[0027] refer to Figure 3 The outer side of the nozzle 82 surface is fixedly connected with a magnetic ring 9, and the inner side of the magnetic ring 9 is magnetically adsorbed to the outer side of the support seat 81.

[0028] As a technical optimization solution of the utility model, by setting the magnetic ring 9, when the user inserts the nozzle 82 into the support seat 81 for placement, the nozzle 82 will drive the magnetic ring 9 to move synchronously. When the magnetic ring 9 is close to the outer side of the support seat 81, the inner side of the magnetic ring 9 will be magnetically adsorbed to the outer side of the support seat 81, thereby improving the stability of the placement of the nozzle 82.

[0029] refer to Figure 1 A time relay 10 is fixedly connected to the top of the front side of the crusher body 1, and the time relay 10 is electrically connected to the electric telescopic rod 5 through a wire.

[0030] As a technical optimization scheme of the utility model, by setting a time relay 10, the user can output two timing programs to the time relay 10 before using the electric telescopic rod 5. When the first timing of the time relay 10 ends, the second timing is started. At the same time, the time relay 10 will send an electrical signal to make the electric telescopic rod 5 drive the clearing head 6 to move downward to clear the blockage. When the second timing of the time relay 10 ends, the first timing is started. At the same time, the time relay 10 will send an electrical signal to start the electric telescopic rod 5 to drive the clearing head 6 to reset. This cycle has the effect of timing control of the electric telescopic rod 5.

[0031] refer to Figure 2 A mounting plate 11 is fixedly connected to the top of the surface of the discharge hopper 3 . Three mounting plates 11 are arranged in a ring shape. The mounting plates 11 are fixedly connected to the crusher body 1 by bolts.

[0032] As a technical optimization solution of the utility model, by setting the mounting plate 11, when the discharge hopper 3 needs to be disassembled and the electric telescopic rod 5 inside needs to be replaced, the user can use the handle to rotate the bolt to loosen and remove the bolt, and then the user can remove the discharge hopper 3 and inspect the electric telescopic rod 5 inside.

[0033] refer to Figure 2 The top of the protective cover 71 is fixedly connected with a conical cover 12, and the material of the conical cover 12 is PP plastic.

[0034] As a technical optimization solution of the utility model, by setting the conical cover 12, the user can use the conical cover 12 to guide the fallen rapeseed debris to the outside when using the protective cover 71 to protect the electric telescopic rod 5, thereby avoiding the fallen rapeseed debris from accumulating on the top of the protective cover 71.

[0035] The working principle and use process of the utility model are as follows: when in use, first put the rapeseed into the feed pipe 2, and then the feed pipe 2 will guide the rapeseed into the interior of the crusher body 1, and then the crusher body 1 is opened to crush the rapeseed, and then the crushed rapeseed will be conducted to the discharge hopper 3 and discharged through the discharge port 4. In the process of discharging the crushed rapeseed, if the discharge port 4 is blocked by rapeseed, the user can turn on the electric telescopic rod 5 so that the electric telescopic rod 5 drives the clearing head 6 to move downward to clear the rapeseed blocked by the discharge port 4. In the process of using the electric telescopic rod 5, the protective cover 71 can be used to protect the electric telescopic rod 5. The electric telescopic rod 5 can be protected from rapeseed debris hitting the surface of the electric telescopic rod 5 for a long time and causing damage to the electric telescopic rod 5. The support rod 72 can then be used to support the electric telescopic rod 5 in mid-air to ensure stability in use. When a large amount of rapeseed debris is attached to the surface of the cleaning head 6 and needs to be cleaned, the user can first start the electric telescopic rod 5 to drive the cleaning head 6 to move downward to the bottom of the discharge head. Then the user can take the nozzle 82 out of the support seat 81, point the jet end of the nozzle 82 toward the surface of the cleaning head 6, and then use the air flow of the air source to spray through the nozzle 82, so as to spray off the rapeseed debris on both sides of the cleaning head 6 attached to the surface, thereby having the ability to assist in clearing blockages.

[0036] In summary: the rapeseed oil pressing pretreatment device is provided with an electric telescopic rod 5. If rapeseed blocks the discharge port 4 during the process of discharging crushed rapeseed, the user can turn on the electric telescopic rod 5 to make the electric telescopic rod 5 drive the clearing head 6 to move downward to clear the rapeseed blocked by the discharge port 4, thereby solving the problem of lack of a clearing structure. When the discharging hopper is discharging, if there are too many crushed rapeseeds, they are easily accumulated and blocked at the discharge port of the crushing device, resulting in the inability to discharge the material, thereby reducing the crushing efficiency of the crushing device.
