[0011] Figure 3 It is a schematic diagram of the slide gate valve switching mechanism in the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0012] The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0013] Please refer to Figure 1The hopper 1 is fixed on the upper part of the frame 2, and the hopper 3 is located just below the discharge port 11 of the hopper 1. The hopper 3 is located in the middle of the frame 2. The hopper 3 is located at the bottom of the hopper 3 and drives the hopper 3 to move. The hopper 5 is fixed at the middle of the bottom of the hopper 3 and extends upward. When unloading is not required, the hopper valve mechanism completely blocks the discharge port of the hopper. When unloading is required, the switch mechanism drives the hopper valve mechanism to move to just below the discharge port and ensures that the discharge port, the hopper valve mechanism and the hose are on the same vertical line. In this way, the material in the hopper flows out through the hose, and the unloading control is automatically completed.

[0014] like Figure 2 As shown, the gate valve mechanism 3 includes a bottom plate 31, a valve plate 32, a T-shaped pull-out plate 33, two rows of springs 34, a pair of guide copper pressure plates 35 and a pressure plate 36. The bottom plate 31 is provided with a feeding hole 37, and the feeding hole 37 is docked with the discharge port of the discharge barrel. The valve plate 32 is fixed in the middle of the T-shaped pull-out plate 33 and is located directly below the feeding hole 37. The T-shaped pull-out plate 3 cooperates with the gate valve switching mechanism, and the movement of the T-shaped pull-out plate is driven by the gate valve switching mechanism to realize the discharge control. The gate valve switching mechanism pulls the T-shaped pull-out plate and drives the valve plate to move together. The T-shaped pull-out plate and the valve plate are pulled out, and the powder can fall. The T-shaped pull-out plate and the valve plate are pushed back to their initial position. In the initial state, the powder cannot fall, that is, it is in a closed state. The pressure plate 6 is arranged at the bottom of the base plate 1, and the T-shaped pull-out plate 3 is located between the base plate 1 and the pressure plate 6. The two rows of springs 4 are respectively arranged in the spring placement holes 61 on both sides of the pressure plate 6 and the top is fixedly connected to the bottom of the guide copper pressure plate 5. The top of the guide copper pressure plate 5 is in contact with both sides of the bottom of the T-shaped pull-out plate 3. The valve plate can be pushed upward by the tension of the spring, and the sealing effect is good. The surface of the guide copper pressure plate is relatively soft, and the T-shaped pull-out plate is a hard plate. The T-shaped pull-out plate moves on the guide copper pressure plate when it is pulled back and forth. It is actually soft contact, which causes less wear on the surface of the T-shaped pull-out plate and has a better protection effect.

[0015] like Figure 3As shown in the figure, the plug valve switching mechanism includes a fixed seat 41, a pair of guide rails 42, a fixing plate 43, a movable plate 44, a lifting cylinder 45, a pair of ejector rods 46, four guide rods 47 and a translation cylinder 48. The pair of guide rails are symmetrically arranged on the fixed seat. The two sides of the fixing plate are slidably arranged on the guide rails through sliders. The translation cylinder is fixedly arranged on one side of the fixed seat and its piston rod is connected to the fixing plate. The movable plate is arranged above the fixing plate. The lifting cylinder is arranged on the fixing plate and its piston rod is connected to the movable plate. The pair of ejector rods are arranged on one side of the movable plate and are correspondingly matched with the jacks. The bottoms of the four guide rods are fixedly arranged at the four corners of the fixing plate through guide sleeves, and the tops extend upward through the movable plate. When discharging is required, the lifting cylinder jacks up the movable plate to move upward. At the same time, the ejector rods on the movable plate are inserted into the jacks of the T-shaped pull-out plate, so that the movable plate is connected to the T-shaped pull-out plate. Then the translation cylinder drives the fixing plate to move and drives the movable plate and the T-shaped pull-out plate to move to directly below the discharge port, so that the discharge port, the material passing hole and the hose are on a vertical plumb line, and thus discharging can be carried out. When discharging is completed, the translation cylinder drives the fixing plate to move and drives the movable plate and the T-shaped pull-out plate to move to the initial position. At this time, the discharge port, the material passing hole and the hose are in a staggered state and discharging cannot be carried out. The lifting cylinder drives the movable plate to move to the initial position to separate it from the T-shaped pull-out plate.

[0016] The beneficial effects of the present invention are as follows: The T-shaped plate realizes the automatic control of pull-out type switching for discharging under the pulling of the switching mechanism, automatically completes without manual operation, has high operation efficiency, low labor intensity, low labor cost, small safety and health hazards, simpler valve body structure, the powder is not easy to enter the valve body and accumulate when falling, the powder is easier to clean when entering the valve body, low failure rate, long service life, low use cost, good use effect, small powder loss and high utilization rate, effectively meeting the use requirements.

[0017] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by those of ordinary skill in the art shall be regarded as not departing from the patent scope of the present invention.
