Description

Technical Field

[0001] The utility model relates to the technical field of screening machines, and more specifically, to a wheat seed impurity removal and screening machine. Background Art

[0002] During the processing of wheat seeds, corresponding screening machines are usually used to remove debris mixed in the seeds. However, there are still some shortcomings in actual use. For example, most existing seed screening machines often screen out seed debris by setting a screen bucket or screen and making it vibrate continuously. However, after the screen has been used for a long time, some impurities and particles may be stuck in the through holes of the screen, causing the screen to be blocked. Moreover, since the screen is usually set inside the screening machine, it is inconvenient to clean the screen, which will delay the normal use of the screening machine to a certain extent, and thus affect the efficiency of removing wheat seed debris. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a wheat seed impurity removal and screening machine to solve the problem in the prior art that the screen device is inconvenient to clean because it is inside the screening machine.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: a wheat seed impurity removal and screening machine, comprising a screening machine body, the wheat seed impurity removal and screening machine also includes

[0005] Connecting column;

[0006] An electric push rod 1, wherein the electric push rod 1 is arranged on the left side of the screening machine body, and an end of the electric push rod 1 away from the screening machine body is fixedly connected to the interior of the connecting column;

[0007] Motor 1, wherein the motor 1 is fixedly mounted on the top of the connecting column, and the drive shaft of the motor 1 is fixedly connected to the mounting column;

[0008] A spring, wherein the bottom end of the spring is fixedly connected to the inside of the mounting column, the top end of the spring is fixedly connected to a movable column, and a screening bucket is fixedly installed on one side of the movable column in the length direction;

[0009] A limit block is provided on a surface on the top of the mounting post, and the surface of the limit block is slidably connected to the interior of the movable post.

[0010] Wherein, it also includes a shielding cover, which is arranged at the bottom of the screening bucket, and the bottom surface of the shielding cover is fixedly connected to a contact seat.

[0011] It also includes a fixed plate, which is fixedly connected to the inner wall of the screening machine body. Motor 2 is fixedly installed on one end of the fixed plate. The driving shaft of motor 2 is fixedly connected to an eccentric wheel, and the surface of the eccentric wheel is in contact with the bottom of the contact seat.

[0012] Among them, it also includes a shielding component, which is arranged on the surface of the screening machine body.

[0013] Among them, the shielding assembly includes an electric push rod 2, a shielding plate, a fan, a connecting pipe 1, a collection box, a connecting pipe 2, and a dust hopper. The electric push rod 2 is arranged on the front of the screening machine body, the shielding plate is fixedly connected to the bottom end of the electric push rod 2, the fan is arranged on the front of the shielding plate, one end of the connecting pipe 1 is fixedly connected to the air outlet of the fan, and the other end of the connecting pipe 1 is detachably connected to the surface of the collection box, and the connecting pipe 2 is detachably connected to the side of the collection box surface opposite to the connecting pipe 1, and the dust hopper is arranged on the surface of the shielding plate, and the surface of the dust hopper can be fixedly connected to the end of the connecting pipe 2 away from the collection box.

[0014] The beneficial effects of the above technical solution of the utility model are as follows:

[0015] The eccentric wheel is driven by the motor at one end of the fixed plate to rotate, so that the eccentric wheel can push the screening bucket up when it contacts the contact seat, and when the eccentric wheel rotates away from the contact seat, the screening bucket is driven to reset under the elastic action of the spring. The wheat seeds can be vibrated and screened by the reciprocating vertical movement of the screening bucket, and the screened impurities fall through the through-holes at the bottom of the screening bucket. When the screening bucket is blocked, the motor is turned off, and the connecting column is driven to move horizontally by the electric push rod to enable the screening bucket to move a certain distance synchronously. At this time, the mounting column is driven to rotate by the motor, so that the screening bucket can rotate horizontally to be rotated out from the inside of the screening machine body. At this time, the screening bucket can be quickly processed, thereby avoiding the situation that the screening bucket cannot be conveniently and quickly processed due to being arranged inside the screening machine body, effectively shortening the time required for the processing process, ensuring the normal progress of the wheat seed impurity removal work to a certain extent, and improving the overall practicality of the device.

[0016] By extending the electric push rod set on the front of the screening machine body and driving the baffle to move downward, the area on the surface of the screening machine body that accommodates the rotation of the screening bucket can be sealed, ensuring the overall sealing of the screening machine body. At the same time, the dust generated during the removal process can be sucked into the dust collecting hopper through the fan and retained in the collection box to prevent dust diffusion from affecting the air quality, further improving the practicality of the device.
