Description

Technical Field

[0001] The utility model belongs to the technical field of screening devices, in particular to an automatic screening device for rapeseed. Background Art

[0002] During the rapeseed production process, rapeseed harvested from the field often contains a variety of impurities. With the continuous expansion of agricultural production, the traditional manual screening of rapeseed can no longer meet the processing needs of a large number of rapeseeds. With the continuous expansion of the edible oil market, the quality requirements for rapeseed are also increasing. Therefore, an automatic rapeseed screening device is needed to screen rapeseed efficiently.

[0003] However, during use of the existing rapeseed automatic screening device, after the screening device vibrates, it takes a certain amount of time for the components to reset by gravity alone. When the vibration frequency or amplitude of the screening device is high, relying on gravity reset will make it difficult for the device to return to its initial state in time between two vibrations, affecting the normal operation of the device. Utility Model Content

[0004] The utility model aims to provide an automatic rapeseed screening device. By setting a reset mechanism, the utility model solves the problem that in the existing automatic rapeseed screening device, after the screening device vibrates during use, it takes a certain time for the parts to reset by gravity alone. When the vibration frequency of the screening device is high or the vibration amplitude is large, relying on gravity reset will make it inconvenient for the device to return to the initial state in time between two vibrations, thus affecting the normal operation of the device.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model discloses an automatic rapeseed screening device, comprising a screening box, wherein a reset mechanism and a vibration screening mechanism are arranged on the screening box;

[0007] The bottom of the screening box is fixedly connected to a collecting box, a circular ring is slidably connected to the outer wall of the screening box, a plurality of supporting legs are fixedly connected to the bottom of the circular ring, a box cover is connected to the outer wall of the collecting box, a reset mechanism includes a plurality of trapezoidal slide grooves provided on the outer wall of the screening box, a plurality of trapezoidal slide blocks are slidably connected to the inner walls of the plurality of trapezoidal slide grooves, a plurality of trapezoidal slide blocks are fixedly connected to the circular ring on one side away from the screening box, and a plurality of supporting plates are fixedly connected to the outer wall of the screening box.

[0008] Furthermore, a plurality of telescopic rods are fixedly connected to the top of the circular ring, the tops of the plurality of telescopic rods are respectively fixedly connected to a plurality of support plates, the outer walls of the plurality of support plates are sleeved with springs, the tops of the plurality of springs are respectively fixedly connected to a plurality of support plates, and the bottoms of the plurality of springs are fixedly connected to the circular ring.

[0009] Furthermore, the vibration screening mechanism includes screening component 1 and screening component 2, the screening component 1 includes fixing sleeves respectively fixedly connected to the outer walls of a plurality of supporting legs, and two supporting plates 2 are fixedly connected between the fixing sleeves.

[0010] Furthermore, a rotating shaft 1 is rotatably penetrated through the support plate 2 located on the left side, a motor is fixedly connected to the left side of the support plate 2 located on the left side, and an output shaft of the motor is fixedly connected to the rotating shaft 1 through a coupling.

[0011] Furthermore, a disc is fixedly connected to the right side extension portion of the rotating shaft 1, and a rotating shaft 2 is rotatably connected between the two supporting plates 2.

[0012] Furthermore, the second screening component comprises two connecting rods fixedly connected to the outer wall of the second rotating shaft, and the right side of the disc is rotatably connected to the connecting shaft.

[0013] Furthermore, two connecting blocks are fixedly connected to the outer wall of the connecting shaft, the tops of the two connecting blocks are respectively hinged to the two connecting rods, the tops of the two connecting rods are hingedly provided with collision blocks, and the tops of the two collision blocks are in contact with the collection box.

[0014] The utility model has the following beneficial effects:

[0015] 1. By setting a reset mechanism, when the collision block moves upward, the collision block will hit the collection box, thereby driving the screening box on the collection box to move upward. When the screening box moves upward, the telescopic rod and the spring will be stretched under the connection of the support plate 1, and the spring will undergo elastic deformation and generate elastic force under the action of this tension. When the collision block is separated from the collection box, the screening box and the collection box will be reset under the elastic force of the spring. When the screening box moves upward, the rapeseed inside is lifted and then reset under the elastic force of the spring. The rapeseed will jump and roll more strongly on the screen, thereby enhancing the screening effect of the device, and can also effectively reduce the damage to the device caused by the collision and extend the service life of the equipment;

[0016] 2. By setting up a vibration screening mechanism, when the rapeseed needs to be screened, the rapeseed to be screened can be poured into the screening box, and the motor can be started. The motor drives the connecting shaft on the disc to rotate around the rotating shaft through the rotating shaft 1. When the connecting shaft rotates, it will drive the connecting rod to move up and down through the connecting block and the rotating shaft 2, so that the screening box on the collecting box vibrates, and the vibration screening of the rapeseed is completed, so that the rapeseed can be continuously jumped and turned in the screening box, avoiding the accumulation of rapeseed on the screen and clogging the screen holes, and allowing each rapeseed to have more opportunities to contact the screen holes, thereby completing the screening process more efficiently, greatly improving the screening efficiency.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
