Specifically, a first arc-shaped opening 211 is arranged on one side of the moving portion 21, a second arc-shaped opening 222 is arranged on the sloping platform 221, and the middle portion of one side of the guiding portion 22 is of a sloping platform 221 structure, and the moving portion 21 and the opening on the guiding portion 22 are arranged oppositely and combined to form a circular hole matched with the valve port 6. The driving device 4 is connected with the guide portion 22 through the valve rod 3, the driving device 4 can drive the valve plate 2 to move so that the circular hole and the circular valve port 6 move relatively, specifically, the valve rod 3 is fixedly connected with one side of the guide portion 22, which is far away from the ramp 221, so that the moving direction of the valve rod 3 is always consistent with the moving direction of the circular valve port 6. The drive 4 may be a hydraulic drive 4 or an electric motor drive 4 or a pneumatic drive 4.
Meanwhile, it should be noted that the inclined platform 221 is inclined upward along a direction away from the moving portion 21 to be flush with the top surface of the guide portion 22, the length of the inclined platform 221 is greater than the radius of the second arc-shaped opening 222 and less than the total length of the guide portion 22, the width of the inclined platform 221 is the same as the diameter of the second arc-shaped opening 222, that is, both sides of the inclined platform 221 in the x-axis direction and the side of the guide portion 22 close to the driving device 4 are both platform structures, and the side cross section of the inclined platform 221 is in a right-angled ladder shape. The sloping platform 221 is used for enabling large materials to be clamped when the valve plate 2 is closed, the materials can slide upwards along the sloping platform 221 under the action of thrust, and meanwhile, the platform structure is used for reducing the probability that the materials enter the valve box 1.
Specifically, when the gate valve is in an open state, the circular hole is aligned with the valve port 6, the moving portion 21 is located in the valve box 1 on the left side of the valve port 6, the guide portion 22 is located in the valve box 1 on the right side of the valve port 6, and a material can be discharged from the discharge port through the valve port 6. When the gate valve needs to be opened again, the valve plate 2 is driven to move back to the right by controlling the driving device 4 to be matched with the valve port 6, and then the blanking can be continued. It should be emphasized that the height and width of the valve plate 2 are matched with the height and width of the inner wall of the valve box 1, that is, the outermost end face of the valve plate 2 is always attached to the inner wall of the valve box 1 in the moving process, and based on the moving track of the valve plate 2, it can be found that the spaces in the valve box 1 on the right side of the valve port 6 and the valve box 1 on the left side of the valve port 6, which are far away from the valve port 6, are always kept in a closed state, thereby reducing the possibility of materials entering the valve box 1.
When materials are brought into the valve box 1 on the left side of the valve port 6, the peripheral side of the first arc-shaped opening 211 on the moving part 21 is attached to the valve box 1, so that the entering materials are inevitably arranged in the inner periphery of the first arc-shaped opening 211, when the gate valve is opened again, namely the guide part 22 moves back to the right, the materials can be pushed back into the valve port 6 by the inner wall of the first arc-shaped opening 211 and fall from the discharging pipe, and therefore, the automatic cleaning of the residual materials in the valve box 1 is realized.
Furthermore, as shown in fig. 1, 2 and 5, since the guide part 22 is provided with the ramp 221, when the valve rod 3 has the minimum movement stroke, that is, when the circular hole is aligned with the valve port 6, a gap communicated with the blanking pipe is formed between the guide part 22 and the valve box 1 on the right side of the valve port 6, and therefore, the cleaning mechanism 5 is arranged above the gap to clean the material in the valve box 1 on the right side of the valve port 6.

Meanwhile, it should be noted that the connecting member is rectangular, and the connecting member is partially embedded in the fixing groove all the time in the movement process. When the gate valve is closed, the valve box 1 on the right side of the valve port 6 is in a completely closed state, at this time, the connecting piece, the roller 53 and the cleaning piece 54 are completely compressed in the fixing groove under the action of the pressure on the top of the guide part 22, the ramp 221 gradually enters the valve box 1 on the right side of the valve port 6 along with the opening of the gate valve, a gap is generated in the valve box 1 on the right side of the valve port 6, and at this time, based on the elastic force of the spring 52, the connecting piece, the roller 53 and the cleaning piece 54 move downwards and abut against the surface of the ramp 221, so that materials adhered to the ramp 221 are swept into the blanking pipe again, and the automatic cleaning of the residual materials in the valve box 1 is realized. It should be added that the diameter of the cleaning element 54 sleeved on the roller 53 should be smaller than the width of the connecting element to ensure that the cleaning element 54 and the roller 53 can normally enter the fixing groove.
In the second embodiment of the present invention, as shown in fig. 6, a discharging chute 8 is connected between one side of the valve box 1, which is away from the driving device 4, and the discharging pipe, the discharging chute 8 is respectively communicated with the inside of the valve box 1 on the left side of the valve port 6 and the discharging pipe, and the purging mechanism is installed on the inner wall of the upper portion of the valve box 1 above the discharging chute 8. The diameter of the end face of the top of the blanking chute 8 is larger than that of the round hole, and the position of the top of the blanking chute 8 corresponds to the position of the round hole when the gate valve is in a closed state, so that materials brought into the valve box 1 can normally fall into the blanking chute 8. The purging mechanism comprises an air pipe 9 embedded in the inner wall of the upper portion of the valve box 1, the air pipe 9 is coiled into an arc shape equal to the diameter of a round hole, specifically, the inner diameter of a circular ring formed by coiling the air pipe 9 is equal to the diameter of the round hole, the air pipe 9 is fixedly connected with the valve box 1 through a fixing assembly, a plurality of air holes are formed in the air pipe 9 and used for purging residual materials on the round hole into the blanking chute 8, and the air holes are inclined towards the inner side of the round hole from the outer side of the round hole. And it should be noted that the inner wall of the upper part of the valve box 1 is provided with a groove matched with the air pipe 9, the air pipe 9 can be fixed in the groove through fixing components such as a binding band, a bolt, a clamping block and the like, the purging mechanism further comprises an air pump arranged outside the gate valve, and the air pump is connected with an air inlet of the air pipe 9.
Specifically, when the gate valve is closed, the round hole just moves to the top of the blanking chute 8, most of materials brought into the valve box 1 are pushed to the top of the blanking chute 8 under the action of the inner wall of the round hole and slide downwards again to enter the blanking chute, at the moment, a small part of materials are adhered to the inner wall or the edge of the round hole, then the air pump is opened, air is discharged from the air hole through the air pipe 9 and blown to the round hole, so that the materials adhered to the edge of the round hole are blown into the blanking chute 8, and self-cleaning of the materials in the valve box 1 on the left side of the valve port 6 is realized.
