[0030] The lower end of the discharge port 1 is connected to a ton bag, and a pipe body 11 for the passage of materials is provided between the ton bag and the discharge port 1 .

[0031] like Figure 1-3 As shown, a manual bag clamping device is provided on the discharge port 1, and the manual bag clamping device includes a tightening part 6 and a guard arm 4 for fixing the tightening part 6. The tightening part 6 is arranged around the outer wall of the tube body 11 and is used to fix the ton bag. The tightening part 6 is an elastic material, which is a silicone strip in Example 1, and is used to achieve compression of the upper edge of the ton bag.

[0032] The guard arm 4 circumferentially surrounds the outside of the tube body 11 of the discharge port 1, and the guard arm 4 is connected to the tube body 11 through a connecting plate 3. Specifically, the connecting plate 3 includes a first connecting plate 31 perpendicular to the outer wall of the tube body 11 and a second connecting plate 32 perpendicular to the first connecting plate 31. The first connecting plate 31 and the second connecting plate 32 are fixedly connected by bolts, and the end of the second connecting plate 32 is connected to the hinged end of the guard arm 4. During actual use, the connecting plate 3 can also be other connection methods or shapes, which can realize the connection between the guard arm 4 and the tube body 11, and form a space for accommodating the tightening part 6 between the guard arm 4 and the tube body 11.

[0033] The guard arm 4 includes a free end and a hinged end. The hinged end of the guard arm 4 is hinged to the connecting plate 3 of the guard arm 4, and the free end of the guard arm 4 forms an upper and lower overlap. Specifically, the guard arm 4 includes a first guard arm 41 and a second guard arm 42. The hinged ends of the first guard arm 41 and the second guard arm 42 are hinged to the connecting plate 3 and are arranged around the outer wall of the tube body 11. The free ends of the first guard arm 41 and the second guard arm 42 form an upper and lower overlap. In Example 1, the free end of the first guard arm 41 is located below the free end of the second guard arm 42, and the free ends of the first guard arm 41 and the second guard arm 42 are connected by a buckle 5.

[0034] Specifically, through holes are respectively provided on the hinged ends of the first guard arm 41 and the second guard arm 42 and the second connecting plate 32. The hinged ends of the first guard arm 41 and the second guard arm 42 are hinged on the second connecting plate 32 by bolts to realize the opening or tightening of the guard arm 4.

[0035] The free end of the first guard arm 41 and the free end of the second guard arm 42 are connected by a buckle 5, and the buckle 5 includes a fixing cavity 41 opened at the upper and lower parts, and the fixing cavity 41 is respectively arranged below the first guard arm 41 and above the second guard arm 42. The two ends of the tightening part 6 are respectively placed in the fixing cavity 46, and the two ends of the tightening part 6 are respectively fixed to the free ends of the first guard arm 41 and the second guard arm 42 through the fixing piece, so that the tightening part 6 forms an annular shape staggered up and down and is arranged around the outer wall of the tube body 11. The fixing piece can be a bolt, which drives the tightening part to loosen or tighten on the outer wall of the tube body 11 when the guard arm 4 is opened or tightened.

[0036] By using the manual clamping device of the present application to install ton bags, it only takes 2 minutes to install one ton bag, compared to 10 minutes required for direct bundling with hemp rope, which effectively shortens the installation time, reduces scalding accidents, improves safety, reduces product powder spraying and the phenomenon of burrs of hemp rope flowing into the product, and improves product quality.

[0037] The ton bag has good airtightness. When filling the ton bag with material, the material continuously enters the ton bag from the ton bag opening, bringing in air at the same time, causing the air pressure in the ton bag to increase. Excessive air pressure, on the one hand, affects the stability of the ton bag clamping, causing the ton bag to easily detach from the discharge port 1, and on the other hand, the product, especially the dusty and granular product, is prone to splashing. To solve this problem, the present application further provides a breathing valve 7 on the pipe body 11. The breathing valve 7 includes a filter and an air guide 71. The air guide 71 is provided on the side wall of the pipe body 11 at the discharge port 1 and is connected to the pipe body 11. The filter is provided in the air guide 71.

[0038] The mesh size of the filter is selected according to the particle size of the product. To prevent the product from being discharged from the filter during pressure relief, thereby affecting the yield, the mesh size of the filter is smaller than the particle size of the product. In Example 1, the particle size of the filter is set to 100-325 mesh.

[0039] However, if too much product splashes, a large number of particles will be blocked in the filter, causing blockage of the device. Therefore, it is preferred that the end position of the breathing valve 7 is located above 3 / 10 of the height of the tube body 11, and the end position of the filter is located above 1 / 2 of the height of the tube body 11.

[0040] Furthermore, the breathing valve 7 and the tube body 11 are detachably connected.

[0041] Specifically, if Figure 6 As shown, the air guide tube 71 is provided with a connecting ring 72 protruding outward, and the connecting ring 72 is composed of two coaxial parts, including a connecting ring A and a connecting ring B. The connecting ring A and the connecting ring B are detachable, and the connecting ring A is provided at the end of the filter facing the breathing valve, and the connecting ring B is provided at the end of the breathing valve facing the air guide tube 71. The connecting ring A and the connecting ring B are coaxially integrally formed, and the connecting ring A and the connecting ring B are connected by a buckle 73. The buckle 73 is sleeved on the protrusion of the connecting ring 72 to achieve the fixation of the connecting ring 72. The protrusions of the connecting ring A and the connecting ring B form a receiving groove 74 in the air guide tube 71, and the filter is placed in the receiving groove 74.

[0042] The present application realizes the tightening of the tightening part 6 by the guard arm 4, so that the tightening part 6 is pressed tightly at the mouth of the ton bag to achieve the clamping of the ton bag mouth. Furthermore, a breathing valve 7 is provided on the side wall of the tube body 11 to prevent the ton bag from falling off due to excessive pressure.

[0044] like Figure 4-5 As shown, the buckle 5 includes a mounting seat 51, a rotating rod 52, a connecting rod 53, a positioning pin 54, and a locking slot 56. The mounting seat 51 is provided on the outer side of the free end of the first guard arm 41, and the mounting seat 51 is rotatably connected to the rotating rod 52. The mounting seat 51 is provided with a positioning pin 54, which is parallel to the wall surface of the first guard arm 41 and has a through hole for the connecting rod 53 to pass through. The second guard arm 42 is provided with a locking slot 56. One end of the connecting rod 53 passes through the positioning pin 54 through the through hole, and the other end extends into the opening of the locking slot 56. Preferably, the connecting rod 53 passes through the positioning pin 54 and is threaded at one end. The connecting rod 53 is screwed onto the connecting rod 53 by a bolt to achieve positioning and tightening of the connecting rod 53.

[0045] When it is necessary to pack the bags, the rotating rod 52 is pressed down so that the rotating rod 52 and the connecting rod 53 are in the opposite direction and parallel. One end of the connecting rod 53 is clamped in the clamping groove 56, and the other end is abutted against the positioning pin 54 through a bolt, so as to clamp the first guard arm 41 and the second guard arm 42, thereby tightening the tightening part 6; when it is necessary to unload the bags, the rotating rod 52 is lifted so that the rotating rod 52 and the connecting rod 53 are perpendicular to each other, so as to loosen the first guard arm 41 and the second guard arm 42, thereby loosening the tightening part 6.

[0046] Example 3

[0047] In Example 3, the clip 73 includes a first clip arm and a second clip arm, which are hinged to each other, and the first clip arm and the second clip arm are provided with a free end and a hinged end, and the hinged ends of the first clip arm and the second clip arm are hinged to each other, wherein the free end of the first clip arm is provided with a fastener, and the fastener is provided with a thread, and a threaded hole is provided on the free end of the second clip arm, and the free end of the first clip arm passes through the threaded hole on the second clip arm to realize the connection of the clip 73, thereby realizing the detachable connection of the breathing valve 7.
