DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0022] Combination Figure 1-Figure 5 A discharging protection structure for a grain-rough separation screen comprises a first discharging member 1 and a second discharging member 2. A movable hinge 3 is fixedly installed on the outer surface of the first discharging member 1. One end of the first discharging member 1 is movably connected to one end of the second discharging member 2 through the movable hinge 3. A transmission component 4 is fixedly connected to one side of the first discharging member 1. A buffer component 5 is fixedly connected to the upper surface of the second discharging member 2. The buffer component 5 comprises a buffer plate 51 movably connected to the inside of the second discharging member 2. A buffer component 52 is fixedly connected to the upper surface of the second discharging member 2. The transmission component 4 is used to transmit the grain stored in the first discharging member 1. The buffer component 5 is used to play a buffering role when the grain flows in the second discharging member 2, thereby reducing the impact force when the grain is discharged, thereby reducing the flying of dust and debris and achieving a better protection effect.

[0023] The first material discharge component 1 includes a mounting component 11 arranged at the feed port, and the entire structure is installed at a specified position through the mounting component 11. A motor fixing component 42 is fixedly installed on the outer surface of one side of the first material discharge component 1, and a rotating motor 41 is fixedly connected to one side of the motor fixing component 42. The rotating motor 41 is fixedly installed on one side of the first material discharge component 1 through the motor fixing component 42. The output shaft of the rotating motor 41 is connected to the rotating component (43), and the output shaft of the rotating motor 41 drives the rotating component 43 to rotate. When grains enter the first material discharge component 1, the rotating component 43 rotates to push the grains into the second material discharge component 2, thereby realizing grain transmission.

[0024] The buffer plate 51 is provided with a plate body 511, and the plate body 511 is in an arc shape. A connecting hole 512 is provided inside the buffer plate 51, and the buffer plate 51 is movably connected to the inside of the second feeding piece 2 through the connecting hole 512. The buffer member 52 includes a cylinder 523, and a spring 522 is provided inside the cylinder 523. One end of the spring 522 is movably connected to a top cap 521. A thread is provided on the outer surface of the cylinder 523, and a first fixing nut 524 and a second fixing nut 525 are threadedly connected to the outer surface of the cylinder 523. The buffer member 52 is fixedly connected to the upper surface of the second feeding piece 2 by the coordinated use of the first fixing nut 524, the second fixing nut 525 and the cylinder 523. When grains enter the second feeding piece 2, they will impact the buffer plate 51, and the buffer plate 51 will push the top cap 521 to squeeze the spring 522, and the elastic force of the spring 522 is used to offset the impact force of the grains, thereby achieving a buffering effect.

[0025] When in use, the discharging protection structure for the grain-rough separation screen is installed at the discharging position of the grain-rough separation screen through the mounting part 11. When grains enter the first discharging part 1, the rotating motor 41 is started to drive the rotating part 43 to rotate, and the rotation of the rotating part 43 is used to push the grains into the second discharging part 2. At this time, the grains will impact the buffer plate 51, and the buffer plate 51 rotates and squeezes the top cap 521 at the front end of the buffer part 52. The top cap 521 squeezes the spring 522 in turn, and the impact force of the grains is reduced by the spring 522, so as to realize the discharging buffer function. In the process of use, the discharging can be paused by turning off the rotating motor 41, so as to realize the discharging control. Through the setting of discharging control and discharging buffer, the grains can be discharged smoothly, the flying of dust and debris in the grains can be reduced, the quality of the working environment can be improved, and the protection effect can be achieved.
