Description

Technical Field

[0001] This utility model relates to the field of pesticide plant protection machines, specifically a folding sprayer type pesticide plant protection machine. Background Technology

[0002] A pesticide spraying machine is a type of machinery used in agricultural production. It is mainly used to spray pesticides and fertilizers to control pests and diseases and increase crop yield. It typically consists of a power system, a spraying system, and a control system. It can adjust parameters such as spray volume and spraying angle according to crop type and pesticide requirements. The spraying boom is usually installed at the head or tail of the pesticide spraying machine. In order to increase the area of ​​pesticide spraying, the spraying boom usually needs to be folded.

[0003] Existing folding sprayer sprayers typically use a movable connection, where the sprayer is folded up after spraying and secured with ropes. However, this method is cumbersome, and the folded sprayer is exposed on the outside, affecting its appearance. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a folding sprayer for pesticide plant protection, in order to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a foldable spraying rod pesticide plant protection machine, comprising a pesticide plant protection machine body, a mounting frame installed on one side of the pesticide plant protection machine body, and a first spraying rod provided on one side of the mounting frame, and second spraying rods movably installed on both sides of the mounting frame, a first liquid inlet pipe provided at the bottom of the mounting frame and connected to the first spraying rod, a second liquid inlet pipe provided inside the mounting frame, and two sets of flexible hoses provided on one side of the second liquid inlet pipe, a rectangular block provided at the end of the flexible hose, and a mounting block fixed at the top of the rectangular block, the rectangular block being fixedly connected to the second spraying rod, and multiple sets of nozzles provided at the bottom of both the second and first spraying rods, a rotating rod movably installed at the top of the mounting frame, and a guide groove provided on the outer wall of the rotating rod, a circular hole provided on the inner wall of the mounting block, and a guide block fixed on the inner wall of the circular hole, the guide block being located on the inner wall of the guide groove, and limit components provided at both ends of the rotating rod.

[0006] By adopting the above technical solution, the traditional rope fixing method is replaced. Through the cooperation of the guide block and the guide groove, the rotation of the rotating rod can drive the two sets of second spray rods to slide out from the inside of the mounting frame to both sides. After sliding to the end, the insertion rod is inserted into the insertion hole, which prevents the rotating rod from rotating and ensures that the second spray rod can be more stable when working. The two sets of second spray rods are stored inside the mounting frame, avoiding exposure on the outside, which is also more aesthetically pleasing.

[0007] The present invention is further provided that the mounting bracket has a storage groove inside and through holes on both sides.

[0008] Preferably, the rectangular block can be conveniently stored in the storage slot, and the hose can also be stored. The hose allows the rectangular block to connect to the second liquid inlet pipe when it moves, ensuring that the liquid can enter the interior of the second spray bar. The through hole prevents the second spray bar from contacting the mounting bracket when it moves.

[0009] The present invention is further configured such that fixing rods are fixed on both sides of the rectangular block, and the inner wall of the mounting bracket is provided with a moving groove that matches the fixing rods.

[0010] Preferably, the fixed rod and the movable groove cooperate with each other, so that the rectangular block will not fall into the storage groove.

[0011] The present invention is further configured such that a support rod is movably mounted on the side of the mounting bracket away from the first spray bar, and a retaining ring is fixed at the end of the support rod. The retaining ring is sleeved on the outer wall of the second spray bar, and a slider is fixed at the end of the support rod away from the retaining ring, and the outer wall of the slider is in contact with the inner wall of the moving groove.

[0012] Preferably, the support rod and retaining ring are designed to facilitate the support of the second spraying rod. The retaining ring is fitted onto the outer wall of the second spraying rod. When the second spraying rod slides outward, the fixing rod contacts the slider, thereby driving the slider to move outward. The retaining ring fits against the outer wall of the second spraying rod, so that the second spraying rod will not wobble when the pesticide plant protection machine is working, making the second spraying rod work more stably.

[0013] The present invention is further configured such that protrusions are fixed on both sides of the slider, and limiting grooves matching the protrusions are provided on both sides of the inner wall of the moving groove.

[0014] Preferably, the protrusions and the limiting groove cooperate with each other, so that the slider slides in a direction on the inner wall of the moving groove, while preventing the slider from separating from the moving groove.

[0015] The present invention is further configured such that the limiting component includes multiple sets of limiting rings fixed on both sides of the mounting frame, and a plug rod is movably installed inside the limiting ring, and the outer wall of the rotating rod is provided with a plug hole.

[0016] Preferably, the limiting ring can limit the insertion rod, so that the insertion rod can only slide on the inner wall of the limiting ring and be inserted into the insertion hole on the outer wall of the rotating rod, thereby limiting the rotating rod and preventing the rotating rod from rotating.

[0017] The present invention is further configured such that a limiting block is fixed to the outer wall of the insertion rod, and the number of limiting rings is four in two groups, with two limiting rings in each group, and the limiting block is located between the two limiting rings.

[0018] Preferably, to facilitate support for the second spraying rod, a retaining ring is fitted onto the outer wall of the second spraying rod. When the second spraying rod slides outward, the fixing rod contacts the slider, thereby driving the slider to move outward. The retaining ring adheres to the outer wall of the second spraying rod, ensuring that the second spraying rod does not wobble when the pesticide plant protection machine is working, making the second spraying rod work more stably.

[0019] The present invention is further configured such that an avoidance groove is provided at the bottom of the retaining ring, and fixing blocks are fixed on both sides of the end of the second spray rod.

[0020] Preferably, the limiting block can prevent the insertion rod from separating from the mounting bracket, thus avoiding the problem of the insertion rod being easily lost.

[0021] The present invention is further configured such that a bidirectional lead screw can be movably mounted on the top of the mounting bracket, and the bidirectional lead screw is threadedly connected to the mounting block.

[0022] Preferably, a bidirectional lead screw can replace the limiting component. By rotating the bidirectional lead screw, according to the lead screw principle, the bidirectional lead screw rotates and drives the mounting block to move to both sides, eliminating the need for manual pushing of the insertion rod to limit the mounting block.

[0023] The present invention is further configured such that a rotating block is fixed in the middle of both the rotating rod and the bidirectional lead screw.

[0024] Preferably, the rotating block allows for easy rotation of the rotating rod and the bidirectional lead screw.

[0025] In summary, the present invention has the following main advantages:

[0026] 1. This utility model replaces the traditional rope fixing method by setting a rotating rod, a second spraying rod, a guide groove, a guide block, and a limiting component. Through the cooperation of the guide block and the guide groove, the rotating rod can drive the two sets of second spraying rods to slide out from the inside of the mounting frame to both sides when it rotates. After sliding to the end, the insertion rod is inserted into the insertion hole to prevent the rotating rod from rotating and to ensure that the second spraying rods can be more stable when working. The two sets of second spraying rods are stored inside the mounting frame to avoid being exposed on the outside, which is also more aesthetically pleasing.

The outer wall of the rotating rod 6 has an insertion hole, and the end of the rod 13 is provided with a magnetic block. The magnetic block is magnetically connected to the rotating rod 6. The limiting rings 14 can limit the rod 13, so that the rod 13 can only slide on the inner wall of the limiting ring 14. The rod 13 is inserted into the insertion hole on the outer wall of the rotating rod 6, thereby limiting the rotating rod 6 and preventing the rotating rod 6 from rotating.

[0047] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 The outer wall of the insertion rod 13 is fixed with a limiting block 15. There are four limiting rings 14 in two sets, with two limiting rings 14 in each set. The limiting block 15 is located between the two limiting rings 14. The limiting block 15 can prevent the insertion rod 13 from separating from the mounting bracket 2, thus avoiding the problem of the insertion rod 13 being easily lost.

[0048] Second embodiment:

[0049] Please see Figures 4-6 The top of the mounting bracket 2 can also be movably mounted with a bidirectional lead screw 7, which is threadedly connected to the mounting block 43. The bidirectional lead screw 7 can replace the setting of the limiting component. By rotating the bidirectional lead screw 7, according to the lead screw principle, the bidirectional lead screw 7 rotates and drives the mounting block 43 to move to both sides, without the need for manual pushing of the insertion rod 13 to achieve the limiting of the mounting block 43.

[0050] For details regarding the above embodiments, please refer to [link / reference]. Figure 6 Both the rotating rod 6 and the double-acting lead screw 7 have a rotating block 9 fixed in the middle, which allows the rotating rod 6 and the double-acting lead screw 7 to be rotated easily.

[0051] In practical operation, the following steps are taken: During operation, pesticide is added to the pesticide tank of the pesticide plant protection machine body 1. Then, the rotating block 9 is rotated, causing the rotating rod 6 to rotate. When the rotating rod 6 rotates, the guide block 45 and the guide groove 61 cooperate, allowing the mounting block 43 to slide on the outer wall of the rotating rod 6, causing the rectangular block 42 to slide on the inner wall of the receiving groove 21. The fixing rods 44 on both sides of the rectangular block 42 slide on the inner wall of the moving groove 44. The second spraying rod 4 slides out from inside the mounting frame 2. When the fixing rod 44 contacts the slider 83, the fixing rod 44 pushes the slider 83. The sliding motion of the rectangular block 42 along the inner wall of the moving groove causes the support rod 8 to slide outward. Subsequently, the retaining ring 81 moves along with the second spraying rod 4. When the rectangular block 42 moves to one side of the inner wall of the receiving groove 21, the rotating rod 6 stops rotating. Then, the insertion rod 13 is pushed so that it is inserted into the insertion hole, thus limiting the rotation rod 6. A magnetic block is provided at the end of the insertion rod 13. The insertion rod 13 is connected to the rotating rod 6 by magnetic attraction. The pump inside the pesticide plant protection machine body 1 works, and the pesticide liquid enters the first spraying rod 3 and the second spraying rod 4. Then, it is sprayed out through the nozzle 5 to achieve the purpose of spraying.

[0052] When the spraying is finished, pull the insert rod 13 outward, and the insert rod 13 will disengage from the inside of the insertion hole 6. Then rotate the rotating rod 6 in the opposite direction. The rotation of the rotating rod 6 in the opposite direction will drive the second spraying rod 4 to move, so that the second spraying rod 4 is stored in the inside of the storage groove 21. When the fixing block 41 at the end of the second spraying rod 4 contacts the retaining ring 81, it will push the retaining ring 81 to one side, thereby driving the support rod 8 to slide, so that the support rod 8 is reset. Then insert the insert rod 13 back into the insertion hole to complete the limiting of the rotating rod 6.
