Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical automation, and more specifically, to a gap adjustment device for the rubbing disc of a grain peeling equipment. Background Technology
[0002] Grain dehulling machines primarily use a grinding disc to dehull grains, including sorghum, corn, millet, and wheat, which are mainly grasses. Because different grains vary in shape and size, and even different varieties of the same crop can differ significantly, the gap between the grinding discs needs to be adjusted to achieve the desired dehulling effect for different crops.
[0003] The inventors discovered that most existing grain dehulling and grain breaking equipment uses a manual adjustment method for the grinding disc gap adjustment device, which is time-consuming and labor-intensive. At the same time, it cannot achieve precise adjustment of the gap distance, which increases the difficulty of the work for on-site equipment debugging personnel. Utility Model Content
[0004] The purpose of this utility model is to provide a gap adjustment device for the rubbing disc of a grain peeling equipment. During the equipment debugging process, the rubbing disc is driven to rotate by a geared motor to change the gap between the rubbing discs. At the same time, the displacement signal is converted into an electrical signal by an encoder and displayed on the screen, which makes it easier for the equipment debugging personnel to make precise adjustments to the equipment and makes it easier to realize remote control.
[0005] This invention is achieved using the following technical solution:
[0006] The rubbing disc gap adjustment device includes an inner rubbing disc, an outer rubbing disc, an outer rubbing disc adjusting gear, a drive gear, a geared motor, an encoder gear, an encoder, an encoder bracket, and a main shaft. The inner rubbing disc is mounted on the rotating main shaft, and the outer rubbing disc is connected to the outer rubbing disc adjusting gear. The outer rubbing disc adjusting gear has threads on its underside, connecting to the working chamber housing via these threads. The geared motor drives the drive gear to rotate, which in turn drives the outer rubbing disc adjusting gear to rotate, thus moving the outer rubbing disc up and down to change the rubbing disc gap. The encoder gear meshes with the outer rubbing disc gear to achieve rotation, and the encoder converts the displacement signal into an electrical signal, allowing the displacement data to be displayed on the screen in real time.
[0007] By adopting the above technical solution, when adjusting the gap between the rubbing discs, the number of rotations of the outer rubbing disc adjustment gear is controlled by the motor, which precisely controls the change in the rubbing disc gap value, making it convenient for debugging personnel to operate and for remote debugging.
[0008] Furthermore, the outer circumference of the adjusting gear on the outer rubbing disc is threaded, and the thread connects it to the working chamber housing. The threaded connection structure is simple, consumes little power, and allows for vertical movement via rotation, making it convenient to operate.
[0009] By adopting the above technical solution, during the adjustment of the rubbing disc gap, the outer rubbing disc adjusting gear rotates, driving the outer rubbing disc to move up and down, thereby changing the gap size. The threaded connection structure is simple, consumes little power, and allows for up and down movement via rotation, making operation convenient.
[0010] Furthermore, the adjustment device employs a geared motor, which drives the external rubbing disc adjustment gear to rotate via a drive gear, and the geared motor also has a built-in braking function.
[0011] By adopting the above technical solution and using a geared motor drive, the labor intensity of equipment commissioning personnel can be reduced, while making the commissioning work more accurate. At the same time, the braking function of the geared motor avoids gap variations caused by vibration, making the equipment more stable.
[0012] Furthermore, the adjustment device uses an encoder, which performs counting by meshing the encoder gear with the external rubbing disc adjustment gear.
[0013] By adopting the above technical solution, the encoder converts the displacement signal of the rubbing disc into an electrical signal and transmits it to the display screen, thereby realizing real-time and remote monitoring.
[0014] In summary, this application has the following beneficial effects:
[0015] This invention provides a gap adjustment device for the rubbing discs of a grain peeling equipment. The device includes an inner rubbing disc, an outer rubbing disc, an outer rubbing disc adjusting gear, a drive gear, a reduction motor, an encoder gear, an encoder, an encoder bracket, and a main shaft. The inner rubbing disc is mounted on the rotating main shaft, and the outer rubbing disc is connected to the outer rubbing disc adjusting gear. The outer rubbing disc adjusting gear has threads on its underside, connecting to the working chamber housing via these threads. The reduction motor drives the drive gear to rotate, which in turn drives the outer rubbing disc adjusting gear to rotate, thereby moving the outer rubbing disc up and down to change the rubbing disc gap. The encoder gear meshes with the outer rubbing disc gear to achieve rotation, and the encoder converts the displacement signal into an electrical signal, allowing the displacement data to be displayed on the screen in real time. When adjusting the rubbing disc gap, the motor controls the number of rotations of the outer rubbing disc adjusting gear, precisely controlling the change in the rubbing disc gap value, facilitating operation by technicians and remote debugging.
