DETAILED DESCRIPTION

[0018] As Figures 1-2 shown, a brush roller for agricultural machinery includes a roller body 1, the outer side of the roller body 1 is planted with brush hairs (such asFigure 1 As shown in the drawings, the roller body 1 is provided with an input hole 11 along the axial direction thereof, a plurality of annular cavities 12 are arranged on the roller body 1, a plurality of one-way output holes 121 are arranged on the side wall of the annular cavities 12, the one-way output holes 121 are conical, which can reduce the blockage of the one-way output holes 121 by external impurities, and the plurality of annular cavities 12 are uniformly arranged along the axial direction of the roller body 1. The input hole 11 is connected with the annular cavities 12 through a communication hole 13.
[0019] By arranging the input hole 11 and the one-way output hole 121, the bristles can be cleaned from inside to outside due to the close proximity of the one-way output hole 121 to the root of the bristles. Compared with the traditional cleaning method, the cleaning effect is better, the dead angle is smaller, the root of the bristles is not easy to be flushed, and the damage to the bristles is smaller.
[0020] As shown in the drawings, Figures 3-5 A cleaning device for a brush roller of an agricultural machine, comprising a base 2, a fixing mechanism is arranged on the base 2, a water storage cavity 21 is arranged in the base 2, an injection hole for supplementing cleaning water is arranged on the side wall of the water storage cavity 21, a driving motor 3 and an air blower 4 are installed on the base 2, and a cavity 5 is further arranged in the base 2, a switching mechanism is arranged in the cavity 5, and the fixing mechanism comprises: A fixing frame 6 is fixedly connected to the side wall of the base 2, an upper support 61 is fixedly connected to the upper end of the fixing frame 6, the upper support 61 comprises a hydraulic cylinder fixedly connected to the upper end of the fixing frame 6, and the output end of the hydraulic cylinder is rotatably connected with an upper stabilizing seat, a lower support 62 for supporting is arranged at the upper end of the base 2, the lower support 62 comprises a lower stabilizing seat, the upper stabilizing seat and the lower stabilizing seat are matched with the two ends of the roller body 1, so that the roller body 1 can be stably arranged between the upper stabilizing seat and the lower stabilizing seat, and the driving motor 3 drives the lower support 62 to rotate; The switching mechanism comprises: A sliding box 71 is sealingly slid in the cavity 5, a conductive sheet 711 is embedded on one end of the side wall of the sliding box 71, a trigger switch of the air blower 4 is embedded on the side wall of the cavity 5 and corresponds to the conductive sheet 711, when the conductive sheet 711 is in contact with the trigger switch (as shown in the drawings), Figure 4 the air blower 4 starts to work, and when the conductive sheet 711 is separated from the trigger switch (as shown in the drawings), Figure 5 the air blower 4 stops working, and a thermal trigger is arranged on the other end of the side wall of the sliding box 71; A vertical partition 72 is fixedly connected to the inner bottom surface of the sliding box 71; The upper end of the communication pipe 73 is communicated with the lower support 62. It should be noted that the upper end of the communication pipe 73 is fixedly connected with the lower end of the lower stabilizing seat, and the lower stabilizing seat is provided with a through hole corresponding to the input hole. In addition, the upper side wall of the sliding box 71 is provided with a strip-shaped slot corresponding to the communication pipe 73, so that the sliding box 71 and the communication pipe 73 can send relative displacement. The lower end of the communication pipe 73 is fixedly connected with a horizontal partition strip 731, and the lower surface of the horizontal partition strip 731 is slidingly and sealingly connected with the upper end of the vertical partition plate 72. The input end of the air inlet pipe 74 is communicated with the exhaust port of the air blower 4, and the output end of the air inlet pipe 74 is arranged on the inner bottom surface of the cavity 5. The sliding box 71 is provided with an air inlet hole corresponding to the air inlet pipe 74. The water inlet pipe 75 is communicated with the water storage cavity 21 at one end and penetrates through the vertical partition plate 72 at the other end.
[0021] In the embodiment, the lower support 62 includes a driven gear rotatably connected to the upper end of the base 2. Specifically, the driven gear is fixedly connected to the lower end of the lower stabilizing seat, and the upper end of the communication pipe 73 penetrates through the driven gear. The output end of the driving motor 3 is fixedly connected with a driving gear, and the driving gear and the driven gear are engaged.
[0022] In the embodiment, the water inlet pipe is composed of a branch pipe, an elastic bellows and an elbow pipe in series. The output end of the branch pipe penetrates through the vertical partition plate 72, and the input end of the elbow pipe extends into the water storage cavity 21.
[0023] In the embodiment, the thermal trigger includes a memory spring 81 sleeved outside the elastic bellows. It should be noted that the memory spring 81 is made of a nickel-titanium memory alloy wire and is stretched when the temperature rises above 40 degrees Celsius. One end of the memory spring 81 is fixedly connected with a heat-conducting strip 82, and the other end of the heat-conducting strip 82 is arranged outside the base 2 and in contact with the lower surface of the driven gear.
[0024] The working principle of the embodiment is as follows: First, the roller body 1 is vertically placed between the upper stabilizing seat and the lower stabilizing seat, so that the through hole of the lower stabilizing seat corresponds to the input hole 11. Then, the upper stabilizing seat is lowered by the hydraulic cylinder, and the roller body 1 is clamped and fixed. Then, the driving motor 3 is started, and the driving motor 3 drives the lower stabilizing seat to rotate through the gear set, so that the roller body 1 rotates rapidly. Under the action of centrifugal force, the gas in the one-way output hole 121 is continuously discharged, so that the water in the water inlet pipe 75 is sucked upward (the water flow direction is shown by the arrow in the middle of the figure). Figure 4 When the water droplets are discharged from the one-way output hole 121, not only can the weight of the impurities such as broken wires and fibers be increased, but also they are more easily separated by being thrown out. In addition, the bristles can be cleaned. Since the lower surface of the driven gear is in contact with the heat-conducting strip 82, as the driven gear continues to rotate, the driven gear and the heat-conducting strip 82 will continue to rub against each other, causing the heat-conducting strip 82 to heat up. The heat-conducting strip 82 conducts the temperature to the memory spring 81, causing the memory spring 81 to heat up as well. When the temperature of the memory spring 81 rises above the abnormal temperature, the memory spring 81 automatically extends. At this time, the memory spring 81 will push the sliding box 71 to move. When the sliding box 71 moves, on the one hand, it will close the water flow path and open the air flow path; on the other hand, it will connect the conductive sheet 711 to the switch of the blower 4 (e.g., Figure 5 As shown), blower 4 is activated, and the warm air generated by blower 4 is continuously output upwards (airflow direction is as shown). Figure 5 (As indicated by the middle arrow), the airflow is discharged from the one-way output hole 121 through the input hole 11, which can further blow away broken threads and fibers, and can quickly dry the bristles. The whole process is simple and convenient.
[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
