[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] A mortar pumping and spraying equipment, such as Figure 1 and Figure 2The equipment includes a spraying equipment body 1, a fixing plate 2, a mounting plate 3, a placement plate 4, and rollers 5 set at the four corners of the bottom of the fixing plate 2. The mounting plate 3 is horizontally mounted on the top of the fixing plate 2, and the placement plate 4 is placed on the top of the mounting plate 3. The mounting plate 3 is provided with a moving part for driving the placement plate 4 to move horizontally on the mounting plate 3. The spraying equipment body 1 is set on the top of the placement plate 4, and a spray gun 7 is provided on one side of the spraying equipment body 1 through a connecting pipe 6.

[0030] like Figure 1 and Figure 2 The user can easily move the entire device using the rollers 5 at the four corners of the bottom of the fixed plate 2. Once moved to a suitable position, the user can hold the spray gun 7 and perform spraying operations through the spraying equipment and connecting pipe 6. When the user straightens the connecting pipe 6 during spraying, the moving component will drive the placement plate 4 to move horizontally on the mounting plate 3, causing the placement plate 4 and the spraying equipment body 1 on the placement plate 4 to move closer to the user. At this time, the spraying range of the device can be increased without moving the entire device, making it simple and convenient to use.

[0031] like Figure 1 and Figure 3 The spraying equipment body 1 has a storage box 8 for storing the connecting pipe 6 on one side near the connecting pipe 6. A counterweight 9 is fitted onto one end of the connecting pipe 6 inside the storage box 8. An infrared transmitter 10 and an infrared receiver 12 are mounted opposite each other at the opening of the storage box. The infrared receiver 12 controls the operation of the moving parts. The purpose of this setting is that when the user holds the spray gun 7 and pulls the connecting pipe 6 out of the storage box 8 until the connecting pipe 6 is straightened, the connecting pipe 6 and the counterweight 9 will be completely outside the storage box 8 and between the infrared transmitter 10 and the infrared receiver 12. At this time, the outer wall of the connecting pipe 6 will block the signal emitted by the infrared transmitter 10. The infrared receiver 12 will then control the moving parts to start working. When the placement plate 4 moves the spraying equipment body 1 towards the user, the counterweight 9 will cause the connecting pipe 6 to re-enter the storage box 8 due to gravity. At this time, the signal emitted by the infrared transmitter 10 will be received by the infrared receiver 12, which will control the moving parts to stop working. It is simple and convenient to use.

[0032] like Figure 3Two sliding rollers 13 are mounted on the end of the storage box 8 away from the spraying equipment body 1, with one sliding roller 13 located directly above the other. The connecting pipe 6 is located outside the storage box 8 and the end near the spray gun 7 passes between the two sliding rollers 13. The purpose of this arrangement is that when the user holds the spray gun 7 and pulls the connecting pipe 6 out of the storage box 8, the connecting pipe 6 will be pulled out of the storage box 8 between the two sliding rollers 13. At this time, the resistance of the connecting pipe 6 when pulling it out of the storage box 8 can be reduced by the two sliding rollers 13, making it easier to pull the connecting pipe 6 out of the storage box 8. It is simple and convenient to use.

[0033] like Figure 4 The moving parts include a first sliding groove 14 formed at the top of the mounting plate 3 and a first sliding plate 15 disposed at the bottom of the placement plate 4 and horizontally slidably connected within the first sliding groove 14. The bottom of the first sliding plate 15 has an elliptical groove 50 and two opposing grooves 16, with the two grooves 16 located on both sides of the elliptical groove 50 and communicating with it. The bottom of the placement plate 4 has a first elliptical plate 17 located within the elliptical groove 50. The bottom of the mounting plate 3 is supported by a first motor 18, with one end of the rotating shaft of the first motor 18 horizontally positioned. A horizontal bar 19 is provided, and a lever 20 is vertically mounted at the end of the horizontal bar 19 away from the first motor 18. The top of the lever 20 extends vertically between the wall of the elliptical groove 50 and the first elliptical plate 17. When the first motor 18 drives the horizontal bar 19 and the lever 20 to rotate, the bottom end of the first slide plate 15 is provided with a guide to guide the lever 20 into one of the grooves 16. The infrared receiver 12 controls the first motor 18 to work. The purpose of this arrangement is that when the infrared receiver 12 controls the first motor 18 to start working, the first motor... The rotating shaft of the first motor 18 drives the lever 20 to rotate along the axis of the rotating shaft of the first motor 18 via the horizontal rod 19. At this time, the lever 20 slides between the groove wall of the elliptical groove 50 and the first elliptical plate 17. When the lever 20 slides close to one of the grooves 16, the guide can guide the lever 20 from between the groove wall of the elliptical groove 50 and the first elliptical plate 17 into one of the grooves 16. Then the lever 20 will abut against one side of the groove wall of the groove 16 and push the first sliding plate 15 through the groove 16 to place it. The plate 4 and the spraying equipment body 1 move towards the user on the mounting plate 3. After the spraying is complete, the user only needs to manually block the signal emitted by the infrared transmitter 10. At this time, the lever 20 will slide from one of the grooves 16 into the space between the elliptical groove 50 and the first elliptical plate 17. Through the above process, the lever 20 slides into the other groove 16. Then, by the cooperation of the lever 20 and the other groove 16, the mounting plate 4 and the spraying equipment body 1 can be moved to the initial position. It is simple and convenient to use.

[0034] like Figure 4 and Figure 5The guide includes a parallelogram plate 21 rotatably connected to the bottom end of the first elliptical plate 17 and located within the elliptical groove 50. The opposite ends of the parallelogram plate 21 abut against one side of the opening of each of the two grooves 16. The bottom end of the first elliptical plate 17 has an arc-shaped groove 22. A push rod 23 located within the arc-shaped groove 22 is provided at the end of the parallelogram plate 21 closest to it. A first compression spring 24 is provided between one side of the push rod 23 and the groove wall of the arc-shaped groove 22. This arrangement is intended so that when the lever 20 slides close to one of the grooves 16, the lever 20 will engage with the parallelogram plate 21. One end contacts and pushes the parallelogram plate 21 to rotate, causing one end of the parallelogram plate 21 to rotate to abut against the other side of one of the grooves 16. At this time, the parallelogram plate 21 will drive the push rod 23 to slide and squeeze the first compression spring 24 in the arc groove 22, so that the first compression spring 24 is in a compressed state. At this time, the lever 20 will slide into one of the grooves 16 along one side of the parallelogram plate 21. When the lever 20 is fully inserted into the groove 16, the first compression spring 24 will push the parallelogram plate 21 to rotate to the initial position through the push rod 23. It is simple and convenient to use.

[0035] like Figure 6The movable component includes a second slide groove 25 at the top of the mounting plate 3 and a second slide plate 26 at the bottom of the placement plate 4, which is horizontally slidably connected to the second slide groove 25. A support plate 27 is horizontally mounted at the bottom of the mounting plate 3, and a third slide groove 28 is opened at the top of the support plate 27. A third slide plate 29 is horizontally slidably connected in the third slide groove 28. A first gear 30 is rotatably connected to the top of the third slide plate 29. Several push posts 31 are vertically provided at the bottom of the second slide plate 26, and each push post 31 is evenly distributed along the length of the second slide plate 26. One push post 31 passes between two adjacent teeth of the first gear 30. An L-shaped bracket 32 ​​is horizontally slidably connected to the bottom of the support plate 27, and a second motor 33 is provided on the bracket 32. One end of the rotating shaft of the second motor 33 passes through the third slide plate 29 and is fixedly connected to the first gear 30. An infrared receiver 12 controls the second motor 33 to work. The purpose of this arrangement is to ensure that when the infrared light is emitted... When receiver 12 controls the second motor 33 to start working, the rotating shaft of the second motor 33 will drive the first gear 30 to rotate. At this time, through the cooperation of the first gear 30 and each push column 31, the second slide plate 26 can be pushed to move the placement plate 4 and the spraying equipment body 1 towards the user on the mounting plate 3. After the spraying is complete, the user only needs to manually block the signal emitted by the infrared transmitter 10. Through the cooperation of the first gear 30 and each push column 31, the placement plate 4 is moved to the farthest distance. Then, the first gear 30 will move to the other side of each push column 31 through one of the push columns. At this time, the first gear 30 will drive the third slide plate 29 to move in the third slide groove 28 and drive the second motor 33 to move. The second motor 33 drives the bracket 32 ​​to move. Then, through the cooperation of the first gear 30 and each push column 31, the placement plate 4 is moved to the initial position. It is simple and convenient to use.

[0036] like Figure 7 and Figure 8The movable component includes a fourth sliding groove 34 at the top of the mounting plate 3 and a second elliptical plate 35 at the bottom of the placement plate 4. A fourth sliding plate 36 is rotatably connected to the bottom of the second elliptical plate 35, and the fourth sliding plate 36 is located within the fourth sliding groove 34 and horizontally slides along it. A second compression spring 37 is provided between one end of the fourth sliding plate 36 and one side of the groove wall of the fourth sliding groove 34. A rack 38 is provided along the circumference of the outer wall of the second elliptical plate 35. A third motor 39 is provided at the bottom of the mounting plate 3. The infrared receiver 12 controls the operation of the third motor 39. One end of the rotating shaft of the third motor 39 passes through the mounting plate 3 and is provided with a second gear 40, which meshes with the rack 38. This arrangement ensures that the second gear 40 and the rack 38 are always meshed by the second compression spring 37. When the infrared receiver... When the third motor 39 starts working, its rotating shaft drives the second gear 40 to rotate. Since the second gear 40 meshes with the rack 38, and the bottom of the second elliptical plate 35 is rotatably connected to the fourth sliding plate 36, and the fourth sliding plate 36 is horizontally connected to the fourth sliding groove 34, when the second gear 40 rotates, the rack 38 drives the second elliptical plate 35 and the placement plate 4 to rotate along the rotation point of the second elliptical plate 35 and the fourth sliding plate 36. This changes the spraying direction of the spraying equipment body 1 on the placement plate 4, and the second elliptical plate 35 drives the fourth sliding plate 36 to move horizontally in the fourth sliding groove 34. At this time, the second compression spring 37 is compressed, which allows the second elliptical plate 35 to drive the placement plate 4 and the spraying equipment body 1 to move towards the user on the mounting plate 3. This makes it simple and convenient to use.

[0037] like Figure 7 and Figure 8 The bottom of the placement plate 4 is vertically provided with several support rods 41, and each support rod 41 is evenly distributed along the circumference of the placement plate 4. The bottom end of each support rod 41 is provided with a ball bearing 42 that contacts the top end of the mounting plate 3. The purpose of this arrangement is that the placement plate 4 can be supported by the cooperation of each support rod 41 and the ball bearing 42. When the second elliptical plate 35 and the placement plate 4 rotate around the rotation point of the second elliptical plate 35 and the fourth sliding plate 36, the ball bearing 42 at the bottom end of each support rod 41 will roll at the bottom end of the fixed plate 2. Each support rod 41 supports the placement plate 4 without affecting the rotation and movement of the placement plate 4, making it simple and convenient to use.

[0038] like Figure 2The fixed plate 2 has placement slots 43 at the four corners of its bottom end, and vertical rods 44 are vertically slidably connected in each of the four placement slots 43. Four rollers 5 are located at the bottom of the four vertical rods 44 respectively. Each of the four placement slots 43 has a cylinder 45 at the bottom, and one end of the piston rod of each cylinder 45 is fixedly connected to the top of the vertical rod 44. The bottom end of the fixed plate 2 has a rubber contact layer that contacts the ground (not shown in the figure). The purpose of this setting is to drive the vertical rods 44 and rollers 5 to move completely vertically into the placement slots 43 through the cylinders 45. At this time, the fixed plate 2 can be placed on the ground, and the rubber contact layer at the bottom end of the fixed plate 2 will contact the ground, thereby reducing the phenomenon of displacement of the fixed plate 2. It is simple and convenient to use.

[0039] like Figure 1 A push rod 46 is provided on one side of the fixed plate 2, and a push switch 47 for controlling the operation of the four cylinders 45 is provided on the push rod 46. The purpose of this setting is to make it easy for the user to push the device to move by means of the push rod 46, which is simple and convenient to use.

[0040] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
