Detailed Implementation

[0042] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0043] This application discloses an adjustable venturi injector with a 3-nozzle configuration. (Refer to...) Figure 1 and Figure 2 An adjustable venturi injector with nozzle 3 includes a spray barrel 1, a nozzle 3, and an adjustment mechanism 4.

[0044] The nozzle has a spray chamber 11 inside. One end of the spray cylinder 1 is connected to a conveying air pump 2. The outer wall of the other end of the spray cylinder 1 has a material conveying port. The adjustment mechanism 4 is connected to the end of the spray cylinder 1 away from the conveying air pump 2. The nozzle 3 is connected to the adjustment mechanism 4 and the spray cylinder 1. The nozzle 3 is integrally formed with the spray cylinder 1. The nozzle 3 has several nozzles 31 with different directions. The adjustment mechanism 4 includes an adjustment guide ball 41. Several guide channels 411 are opened inside the adjustment guide ball 41. Different guide channels 411 are used to connect the spray chamber 11 and different nozzles 31.

[0045] During material conveying, the air pump 2 delivers gas into the spray cylinder 1. After passing through the spray chamber 11 of the spray cylinder 1, the gas generates suction due to the change in space within the spray chamber 11, drawing the material into the spray chamber 11. Then, after passing through the adjusting guide ball 41, the material is transported from the guide channel 411 to the nozzle 31 and ejected. When it is necessary to change the spray direction of the Venturi injector, the adjusting guide ball 41 is rotated, causing the guide channel 411 to change, thereby changing the nozzle 31 from which the material is ejected. This achieves the change of the Venturi injector's spray direction, ultimately simplifying the method of changing the Venturi injector's spray direction and reducing the time spent on changing the Venturi injector's spray direction.

[0046] Reference Figure 1 and Figure 2The spray head is provided with a spherical placement opening 12 near the outer wall of the nozzle 3, the spherical placement opening 12 is threadedly capped with a spherical placement cover 5, a sealing ring is arranged at the joint of the spherical placement cover 5 and the spherical placement opening 12, the spray barrel 1 is provided with a spherical placement cavity 13 near the nozzle 3, and the adjustment guide ball 41 is placed in the spherical placement cavity 13.

[0047] The adjustment guide ball 41 is placed in the spherical placement cavity 13 through the spherical placement opening 12, and then the spherical placement cover 5 is threadedly capped to determine the position of the adjustment guide ball 41 in the spherical placement cavity 13, and the sealing ring arranged at the joint of the spherical placement cover 5 and the spherical placement opening 12 reduces the probability of material leakage from the spherical placement opening 12.

[0048] With reference to Figure 3 , Figure 4 and Figure 5 , one end of the adjustment guide ball 41 is provided with a rotation guide hole 412, the bottom end of the spherical placement cavity 13 is fixedly connected with a spherical rotation rod 42, the spherical rotation rod 42 is rotationally connected with the hole wall of the rotation guide hole 412, the other end of the adjustment guide ball 41 is provided with a rotation control groove 413, the rotation control groove 413 is slidably connected with a rotation control rod 431, the spherical placement cover 5 is provided with a rotation adjustment hole 51, a sealing ring is arranged in the rotation adjustment hole 51, and one end of the rotation control rod 431, which is away from the adjustment guide ball 41, passes through the rotation adjustment hole 51 and is located on the side of the spherical placement cover 5, which is away from the adjustment guide ball 41.

[0049] The adjustment guide ball 41 is connected with the spherical rotation rod 42 through the rotation guide hole 412, so as to determine the rotation direction of the adjustment guide ball 41, and the spherical rotation rod 42 cooperates with the rotation control rod 431 to further determine the rotation direction of the adjustment guide ball 41. When the adjustment guide ball 41 is rotated, the rotation control rod 431 is driven to rotate, and the rotation control rod 431 transmits the rotation force to the adjustment guide ball 41 through the groove wall of the rotation control groove 413, so as to drive the adjustment guide ball 41 to rotate in the spherical placement cavity 13. The rotation control rod 431 is located on the side of the spherical placement cover 5, which is away from the spherical placement cavity 13, through the rotation adjustment hole 51, so as to facilitate the adjustment of the rotation control rod 431 by the staff, and the sealing ring arranged in the rotation adjustment hole 51 can reduce the probability of material leakage from the rotation adjustment hole 51.

[0050] With reference to Figure 1 , Figure 6 and Figure 7, the non-cylindrical section of the rotating control rod 431 is preferably a square column or a hexagonal column. The end of the rotating control rod 431 away from the adjusting guide ball 41 is slidingly connected with a rotating handle 432, and the rotating handle 432 is connected with a plurality of handle positioning rods 4321 in the direction of the ball placement cover 5. The side away from the adjusting guide ball 41 of the ball placement cover 5 is connected with a handle positioning piece 6, and the handle positioning piece 6 is provided with a plurality of positioning holes 61 in the direction of the positioning handle. The handle positioning rods 4321 are slidingly connected with the positioning holes 61. The side wall of the nozzle is provided with a positioning piece mounting groove (not labeled in the figure), and the part of the handle positioning piece 6 outside the ball placement cover 5 is clamped in the positioning piece mounting groove. The end of the rotating control rod 431 away from the adjusting guide ball 41 is fixedly connected with a blocking plate 433, and the blocking plate 433 is located on the side of the rotating handle 432 away from the adjusting guide ball 41. The cross-sectional area of the blocking plate 433 is larger than that of the rotating control rod 431.

[0051] The non-cylindrical section of the rotating control rod 431 cooperates with the rotating handle 432 slidingly connected with the rotating control rod 431, so that the rotating handle 432 can slide on the rotating control rod 431 while transmitting the rotating force received by the rotating handle 432 to the adjusting guide ball 41, thereby driving the adjusting guide ball 41 to rotate. When the rotating handle 432 slides on the rotating control rod 431, the blocking plate 433 limits the maximum distance of the rotating handle 432 sliding on the rotating control rod 431, thereby reducing the probability of the rotating handle 432 sliding too far from the rotating control rod 431. After the staff rotates the rotating handle 432 and completes the adjustment of the adjusting guide ball 41, the rotating handle 432 needs to be moved towards the handle positioning piece 6, so that the handle positioning rods 4321 connected with one end of the rotating handle 432 towards the handle positioning piece 6 are inserted into the positioning holes 61 of the handle positioning piece 6 connected with the ball placement cover 5, thereby determining the position of the rotating handle 432, reducing the probability of the handle positioning piece 6 continuing to rotate after completing the adjustment of the adjusting guide ball 41, thereby reducing the probability of the adjusting guide ball 41 rotating in the ball placement cavity 13, so that the guide flow channel 411 deviates from the spray cavity 11. The positioning piece mounting groove determines the position of the handle positioning piece 6, thereby reducing the probability of the handle positioning piece 6 rotating, thereby reducing the probability of the rotating handle 432 driving the ball placement cover 5 to rotate, causing the ball placement cover 5 to loosen.

[0052] The implementation principle of the embodiment of the nozzle 3 adjustable Venturi injector is as follows: when conveying the material, the conveying gas pump 2 conveys the gas to the spray barrel 1, the gas generates the negative pressure adsorbing the material when passing through the spray cavity 11 of the spray barrel 1 due to the characteristics of the Venturi tube, then the material passes through the guide flow channel 411 in the adjusting guide ball 41 of the adjusting mechanism 4, and finally is sprayed out from the nozzle 3, so that the conveying of the material is realized; when changing the direction of the Venturi tube spraying the material, the adjusting guide ball 41 is rotated, the guide flow channel 411 of the adjusting guide ball 41 is changed, and then the guide flow channel 411 is connected with different nozzles 31, the material is sprayed out from the nozzles 31 in different directions, and then the spraying direction of the Venturi tube is changed, compared with the prior art, the way of changing the spraying direction of the Venturi tube is finally simplified, and the time spent for changing the spraying direction of the Venturi tube is reduced.

[0053] The above are the preferred embodiments of the present application, and do not limit the protection scope of the present application, so: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
