[0026] Specific examples are given below.
[0027] like Figure 1-Figure 5As shown, a quantitative feeding valve for preventing material bridging comprises a valve body 1; a feeding barrel 11 is installed in the middle of the valve body 1; a baffle 12 is provided at the end of the valve body 1, and the baffle 12 and the valve body 1 are matched in shape; a support plate 13 is fixedly connected to the outer wall of the valve body 1; an elastic band 14 is fixedly connected to the end of the support plate 13, and the middle of the elastic band 14 is arranged close to the support plate 13; a bayonet 15 is fixedly connected to the end of the elastic band 14, and the bayonet 15 is arranged to pass through the middle of the baffle 12; two groups of elastic members 16 are fixedly connected to the inner wall of the bayonet 15; a clamping rod 17 is fixedly connected to the end of the elastic member 16, and the clamping rod 17 is slidably arranged on the inner wall of the bayonet 15; when working, the staff needs to connect and fix the top of the valve body 1 to the feeding pipe, and after connecting the feeding barrel 11 to the power supply, the rotating feeding barrel 11 can evenly convey the solid material, by providing a detachable The latch 15 is then pulled back to release the latch 15 from the latch 15, and the latch 15 is released from the latch 15, and the latch 15 is released from the latch 15, and the latch 15 is released from the latch 15. This step, in conjunction with the baffle 12, can facilitate subsequent maintenance or cleaning of the inner wall of the valve body 1 and the surface of the feeding barrel 11, reduce the number of dead corners when cleaning the integrated valve body 1, and reduce the subsequent accumulation of more oil, impurities, etc., which causes the feeding barrel 11 to get stuck when rotating. The provision of a retractable clamping rod 17 can increase the speed at which the staff can remove or install the baffle 12.
[0028] like Figure 4 and Figure 5As shown, the middle part of the support plate 13 is fixedly connected to the limit plate 2; the end of the limit plate 2 is fixedly connected to the top plate 21; the middle part of the top plate 21 is provided with an inner groove 22; the inner wall of the inner groove 22 is rotatably connected to two sets of wheels 23, and the middle part of the wheel 23 is in contact with the middle part of the elastic band 14; the middle part of the top plate 21 is rotatably connected to the screw 24, and the screw 24 is threadedly connected to the support plate 13; during operation, a slidable limit plate 2 is provided on the outer wall of the support plate 13, and after the bayonet 15 and the baffle 12 are locked and fixed, the staff can continue to rotate the end of the screw 24 with the help of a tool, and make the screw 24 synchronously drive the top plate 2 during the rotation process. 1 is unfolded outward, and the elastic band 14 in contact with the two sets of wheels 23 is tightened. The two sets of wheels 23 set in contact with the elastic band 14 can rotate under the action of friction and strengthen the fixation of the baffle 12. In this step, by setting up a top plate 21 that can move up and down, it can reduce the elasticity of the elastic band 14 after long-term use, which makes the baffle 12 loose when being fixed. The moving top plate 21 can adjust the elastic elastic band 14, and the two sets of rotatable wheels 23 can reduce the problem of the elastic band 14 directly contacting the edge of the top plate 21 when unfolding, which may cause greater wear.

After sliding, the first connecting rope 32 is provided to pull the card rod 17 toward the middle of the pin 15, and squeeze the two groups of elastic members 16 to deform the length until the two groups of card rods 17 are stored, and the unfolded first connecting rope 32 can be stored in the gap between the storage groove 3 and the pull rod 31. This step, in conjunction with the provided handle 33, can reduce the problem that the unfolded card rod 17 is in tight contact with the outer wall of the pin 15, making it difficult to synchronously reset the position of the two groups of card rods 17. The provision of a storage groove 3 for accommodating the first connecting rope 32 can reduce the phenomenon of breakage at the connection between the end of the first connecting rope 32 and the card rod 17.
[0030] like Figure 5As shown, the end of the limiting plate 2 is fixedly connected to a support plate 4; the outer wall of the support plate 4 is fixedly connected to a second connecting rope 41; the end of the second connecting rope 41 is fixedly connected to a counterweight ball 42; when working, by arranging a support plate 4 at the end of the limiting plate 2, the support plate 4 can support the second connecting rope 41 and the counterweight ball 42, and when the limiting plate 2 is moving, under the action of the inertia of movement, the counterweight ball 42 can knock on the edge of the limiting plate 2.

[0032] like Figure 3 As shown, a fixing groove 6 is provided on the outer wall of the baffle 12, and the fixing groove 6 and the clamping rod 17 are matched in shape; when working, the fixing groove 6 is provided on the outer wall of the baffle 12, and the raised clamping rod 17 can deeply contact the inner wall of the fixing groove 6 after being stretched. This step cooperates with the setting of the fixing groove 6 to reduce the contact area between the baffle 12 and the clamping rod 17, thereby reducing the phenomenon of slipping.

A slidable pull rod 31 is provided in the middle of the latch 15. When the two sets of clamping rods 17 need to be pressed down for storage, the staff can pull the middle of the handle 33 outward and drive the pull rod 31 to slide on the inner wall of the storage groove 3. The first connecting rope 32 provided in conjunction with the clamping rod 17 is pulled toward the middle of the latch 15 and squeezes the two sets of elastic members 16 to deform in length until the two sets of clamping rods 17 are stored. The unfolded first connecting rope 32 can be stored in the gap between the storage groove 3 and the pull rod 31. A support plate 4 is provided at the end of the limiting plate 2, so that the support plate 4 can support the second connecting rope 41 and the counterweight ball 42.
