DETAILED DESCRIPTION

[0025] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] like Figure 1 , 2 As shown in Figure 4, a powder suction gun for a powder mixing and batching stirring tank includes a gun body 1 and a tail chamber 2, which is movably connected to one end of the gun body 1; the tail chamber 2 includes a sealing plate 21, and the sealing plate 21 and the inner wall of the gun body 1 form a sliding structure, and a plurality of telescopic rods 22 are installed on one side of the surface of the sealing plate 21; the sealing plate 21 is connected to a front end sealing plate 23 through the telescopic rods 22, and the surface size of the front end sealing plate 23 is the same as the cross-sectional size of the inner wall of the gun body 1 and a sliding connection is formed therebetween, and the telescopic rods 22 are used for linearly driving the distance between the front end sealing plate 23 and the sealing plate 21; a crushing mechanism 3 is installed in the middle of one side of the surface of the sealing plate 21, and the crushing mechanism 3 penetrates the surface of the front end sealing plate 23, and the crushing mechanism 3 and the front end sealing plate 23 are relatively movable.

[0027] The tail chamber 2 is tightly connected to one end of the gun body 1, and the airtightness between the two can be increased by sealing threads or sealing gaskets with good airtightness to ensure that there is no leakage between the tail chamber 2 and the gun body 1. The contact parts between the sealing plate 21 and the front end sealing plate 23 and the inner wall of the gun body 1 can be filled with elastic sealing materials to increase the airtightness. The tail chamber 2 can smoothly drive the sealing plate 21 and the crushing component to move forward and clear the blockage by flushing safety gas into the inside. When the powder suction gun is in operation, the tail chamber 2 is in a non-working state, and the inner wall of the gun body 1 of the powder suction gun and the front end sealing plate 23 form a smooth cavity. This allows the powder to be sucked in to complete the normal working process; one end of the crushing mechanism 3 is fixedly connected to the sealing plate 21, and the other end thereof passes through the front end sealing plate 23. When the internal cavity of the gun body 1 is blocked by powder, the telescopic rod 22 starts to operate, and the front end sealing plate 23 is gradually pulled closer to the sealing plate 21, so that the crushing mechanism 3 is exposed, and the crushing and unblocking work can begin; this setting can achieve that the crushing mechanism 3 is hidden behind the front end sealing plate 23 when the suction gun is not blocked, and does not affect the daily operation of the suction gun. Furthermore, when the suction gun is blocked and needs to be unblocked, the crushing mechanism 3 can be quickly called out to start the crushing and unblocking operation.

[0028] like Figure 2 , 4 As shown in , 5 and 7, the pulverizing mechanism 3 includes an opening and closing component 31, and the opening and closing component 31 includes a pulverizing motor 311, which is installed on one side of the surface of the sealing plate 21; a semi-threaded shaft 312 is installed at the output shaft of the pulverizing motor 311, and one end of the semi-threaded shaft 312 is connected to one side of the surface of the rotating chassis 313, and a plurality of grooves are arranged around the surface of the rotating chassis 313; an inner thread brake ring 314 is sleeved on the surface of the semi-threaded shaft 312, and a plurality of brake rods 315 are rotatably connected to the outer wall of the inner thread brake ring 314, and a section of the brake rod 315 is respectively connected to the middle part of the pulverizing cutter head 316; a pulverizing cutter head 316 is rotatably connected to the groove arranged on the surface of the rotating chassis 313, and the number of the pulverizing cutter heads 316 is the same as the number of the grooves arranged on the surface of the rotating chassis 313 and corresponds one to one.

[0029] The bottom of the semi-threaded shaft 312 is rotationally connected to the surface of the rotating chassis 313 through a bearing, and a section of the surface of the semi-threaded shaft 312 is provided with an external thread, and the external thread on the surface of the semi-threaded shaft 312 is adapted to the thread groove on the inner wall of the internal thread brake ring 314; the crushing motor 311 is a servo motor that can run forward and reverse; one end of the brake rod 315 is rotationally connected to the outer wall of the internal thread brake ring 314 through a shaft, and the other end is also rotationally connected to the middle part of the crushing cutter head 316 through a shaft. When the internal thread brake ring 314 is close to one end of the crushing motor 311 on the surface of the semi-threaded shaft 312, the crushing cutter head 316 and the brake rod 315 fit together and are parallel to each other. When the crushing motor 311 starts to run, the semi-threaded shaft 312 is rotationally connected to the surface of the rotating chassis 313 through a bearing Rotation, at this time, cannot drive the rotating chassis 313 to rotate, and the inner thread brake ring 314 is adapted to the outer thread on the surface of the semi-threaded shaft 312, and will start to run along the outer thread toward one end of the rotating chassis 313 due to the rotation of the semi-threaded shaft 312. This brake rod 315 and the crushing cutter head 316 gradually form an angle, prompting the crushing cutter head 316 to rotate around the connecting axis between the rotating chassis 313, gradually away from the central axis of the semi-threaded shaft 312, to achieve opening; conversely, when the crushing motor 311 runs in the reverse direction, the inner thread brake ring 314 runs in the direction of the crushing motor 311, driving the brake rod 315 to retract, so that the crushing cutter head 316 still rotates in the opposite direction around the connecting axis between the rotating chassis 313, thereby gradually recovering to the initial state of being parallel to the brake rod 315.

[0030] like Figure 2 , 4 As shown in Figures 5 and 6, the crushing mechanism 3 also includes a rotating component 32, which includes a limiting toothed ring 321 and a conical drill bit 322; the limiting toothed ring 321 is welded to the end of the outer thread of the semi-threaded shaft 312 close to the rotating chassis 313, and the outer structure of the limiting toothed ring 321 is adapted to the groove set on one side of the inner thread brake ring 314; the conical drill bit 322 is welded to the other side of the rotating chassis 313 away from the semi-threaded shaft 312, and the axis of the conical drill bit 322 is on the axis of the semi-threaded shaft 312.

[0031] The length of the outer thread of the semi-threaded shaft 312 is the length of the working path of the inner brake ring 314. When the inner brake ring 314 is driven by the semi-threaded shaft 312 to rotate toward the rotating chassis 313 to the end of the outer thread, the groove set on one side of the inner brake ring 314 fits with the limit tooth ring 321, thereby limiting the inner brake ring 314 from continuing to move forward; at this time, the crushing cutter head 316 has been fully opened, and the crushing motor 311 continues to run, due to the interaction between the inner brake ring 314 and the limit tooth , so that the position between the inner thread brake ring 314 and the semi-threaded shaft 312 is locked, that is, the semi-threaded shaft 312 can rotate with the inner thread brake ring 314, the brake rod 315, the rotating cutter head and the rotating chassis 313, and the conical drill bit 322 can also rotate together, thereby starting to drill, cut, crush and dredge the powder blocked on the inner wall of the gun body 1. During this process, the tail chamber 2 is continuously filled with gas, so that the sealing plate 21 pushes the entire crushing mechanism 3 forward together, continuously crushing the powder forward and pushing it out of the inner wall of the gun body 1.

[0032] like Figure 2 , 4 As shown in Figures 8 and 9, the powder suction gun also includes a gun head 4, which is coaxial with the gun body 1; a plurality of embedding grooves 41 are evenly arranged on the inner wall of the gun head 4, and a squeezing clamp 42 is attached to the surface of the embedding groove 41; the squeezing clamp 42 is set in a hook shape and passes through the surface of the gun head 4, and at the same time, a lever structure is formed between the squeezing clamp 42 and the gun head 4 through a shaft 43 at the turning point; the squeezing clamp 42 is located at one end of the outer wall of the gun head 4 and is connected to the outer wall of the gun head 4 through a reset spring 44, and a plurality of crushing teeth 45 are provided on one side of the surface of the squeezing clamp 42 located at one end of the inner wall of the gun head 4.

[0033] In actual use, if the gun body 1 is seriously blocked, that is, the inner walls of both the gun body 1 and the gun head 4 are blocked, or the gun body 1 is seriously blocked and cannot be pushed forward to be unblocked by the crushing mechanism 3, the powder in the gun head 4 can be unblocked at the same time, which can be achieved by pressing the squeezing clamp 42 of the gun head 4, and the end of the squeezing clamp 42 located on the surface of the gun head 4 is squeezed hard to make it close to the surface of the gun head 4, and the squeezing clamp 42 can make the end of the squeezing clamp 42 located on the inner wall of the gun head 4 tilt up through its own shape and the lever structure formed with the surface of the gun head 4, so as to squeeze, crush and unblock the blocked powder on the inner wall of the gun head 4; when the suction gun resumes its normal use function, pressure is no longer applied to the squeezing clamp 42 outside the gun head 4, and the reset spring 44 will drive the squeezing clamp 42 to return to its original position, and the end of the squeezing clamp 42 located in the gun head 4 will fit the inner wall of the gun head 4 again, which will not affect the normal use of the suction gun and will not increase the risk of clogging of the suction gun.

[0034] like Figure 1 , 2As shown in FIGS. 3 and 4 , a power tube 11 is welded to the bottom of the gun body 1 , a valve tube 12 is welded to the middle of the surface of the power tube 11 , a valve plug 13 is arranged on the inner wall of the valve tube 12 , and the valve plug 13 and the inner wall of the valve tube 12 form a sliding connection.

[0035] One end of the power tube 11 is connected to a powerful fan through an air duct. The powerful fan is the power source for the daily suction process of the suction gun. One end of the powerful fan is connected to the powder mixing and batching stirring tank, and can also be connected to other storage tank structures. When the suction gun works normally, the valve plug 13 is located on the inner wall of the valve tube 12 to ensure that the inner wall of the power tube 11 is unobstructed, which is convenient for the powder suction work to be completed. When the suction gun is blocked and the tail chamber 2 and the crushing mechanism 3 need to be opened, the valve plug 13 can be moved to the power tube 11 first to block the passage between the gun body 1 and the power tube 11, so as to provide good airtight working conditions for the sealing plate 21 to run in the gun body 1.

[0036] like Figure 1 , 2 As shown in 4, one end of the gun head 4 is movably connected to one end of the gun body 1 through a connecting ring 5; one end of the tail chamber 2 is connected to an inflation tube 6.

[0037] A detachable structure is formed between the gun head 4 and the gun body 1 through a connecting ring 5, which can realize rapid separation or assembly of the gun head 4 and the gun body 1. When the gun body 1 is seriously blocked, the gun head 4 can be removed to reduce the blockage range of the gun head 4 and increase the working efficiency of the crushing mechanism 3. After the dredging is completed, the assembly and recovery work can also be quickly realized; the tail chamber 2 is connected to the high-pressure air pump through the inflation pipe 6, and the high-pressure air pump can provide safety gas for the tail chamber 2, so that the gas in the tail chamber 2 generates pressure to push the sealing plate 21 forward, and provide a forward linear drive for the crushing mechanism 3. While crushing the blocked powder, the powder is pushed to the outside of the gun body 1 to improve the dredging effect.

[0038] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
