Description

Technical Field

[0001] The utility model relates to the technical field of corn harvesters, in particular to a material dividing device for a corn harvester's drop bin. Background Art

[0002] When a corn harvester harvests corn, it cuts the stalks with a cutting table and transports the corn cobs to the peeling rollers for peeling. The peeled corn cobs enter the silo and are collected. In order to expand the capacity of the corn cobs, most common small corn harvesters have two symmetrically arranged silos. Before entering the silo, the corn cobs pass through a flap and are guided by the flap before entering the corresponding silo. The flap generally has a handle, which needs to be manually operated to rotate the flap, so as to guide the corn cobs into different silos according to the inclination direction of the flap. However, this structure requires frequent manual flipping of the flap, which is more labor-intensive and unstable when impacted by the corn cobs. It is easy to flip over by itself, affecting the filling of the silo.

[0003] Therefore, designing a device that can mechanically control the flipping angle to reduce labor intensity and stabilize the working state is exactly the problem that the inventor wants to solve. Utility Model Content

[0018] See also Figure 1 This is a structural view of the utility model, a corn harvester bin dividing device is installed on the frame 13 of the corn harvester, the device is arranged on the side of the outlet end of the peeling roller, and a plurality of cross beams 12 are arranged on the frame 13. The device includes a first bin 7 and a second bin 15. The first bin 7 and the second bin 15 have the same structure. A rectangular unloading opening is opened on the side end surface facing the outside. A movable bin door 10 is hinged at the unloading opening through a hinge. The movable bin door 10 is connected to a control wrench on the handle of the frame 13 through a wire rope. The movable bin door 10 is opened and closed by pulling the wrench to facilitate the unloading of the corn cobs accumulated inside.

[0019] The first silo 7 and the second silo 15 are respectively arranged on both sides of the frame 13 through fixed connecting parts. A first adjusting base 9 is arranged on the side of the first silo 7, and the first adjusting base 9 is connected to the first guide plate 8 by bolts.

The upper end of the connecting plate 2 is connected with a flap 1, and a control box 11 is arranged on the frame 13. A controller is arranged inside the control box 11. The controller is electrically connected to the rotating motor 20 through a wire, and the controller is electrically connected to a control button through a wire. The rotation direction and rotation angle of the rotating motor 20 can be controlled by the control button. When one end of the flap 1 contacts the guide plate, the corn cobs coming out of the peeling roller will fall along the flap 1 into the guide plate and the silo pointed to by the lower end of the flap 1. When the silo is full, the control button can be used to control the motor to rotate and adjust the angle of the flap 1, so that the originally higher end of the flap 1 becomes lower and connects with the guide plate on the other side, thereby guiding the corn cobs coming out of the peeling machine into another silo.

A second position sensor 16 is arranged on the upper part of the side wall of the second silo 15 and is no more than 10 cm away from the top of the side wall. The first position sensor 6 and the second position sensor 16 are electrically connected to the controller arranged on the inner side of the control box 11 through wires respectively. When the position sensor facing the side at the lower end of the flap 1 is triggered, it means that the silo is full of corn cobs. The signal of the position sensor is transmitted to the controller, and the controller controls the rotating motor 20 to perform a specified angle action, that is, switching the guiding direction of the flap 1. The rotation of the rotating motor 20 only performs one action when the position sensor is triggered.

[0022] Buffer strips 5 are provided on the lower end surface of the flap 1 near the edges on both sides. The cross-section of the buffer strip 5 is a semicircular structure. The two ends of the flap 1 are in contact with the first guide plate 8 and the second guide plate 18 through the buffer strips 5 respectively. The buffer strips 5 can effectively reduce the rigid collision between the flap 1 and the guide plate and extend the service life.

[0023] The length of the flap 1 is greater than the distance between the end of the first guide plate 8 and the end of the second guide plate 18, and the flap 1 is butt-jointed with the output end of the peeling roller.

[0024] The utility model adopts a position sensor to sense and cooperate with a rotating motor to control the flap 1 to rotate, and the driver does not need to frequently manually turn the flap 1 to switch the working state of the silo to collect materials. The function of automatically turning the angle to reduce labor intensity and stabilize the working state is achieved.
