Technical Field
[0001] This utility model relates to the field of sprayers, specifically a portable sprayer for controlling locusts in grasslands. Background Technology
[0002] Locusts are pests that can severely damage various plants when they gather in large numbers on grasslands. Therefore, grassland management staff need to spray pesticides on the plants to eliminate locusts.
[0003] Grassland management workers typically fill pesticide sprayers with pesticides, carry the sprayers on their bodies, and then spray the pesticides onto the surface of the plants while walking. This method is an effective way to eliminate locusts.
[0004] However, the current sprayers are fixed to the grassland management staff by tying ropes or straps around them. Not only is the fixing process difficult and cumbersome, but they are also easy to fall off, which makes it very inconvenient for grassland management staff to carry out pesticide spraying. Utility Model Content
[0005] To overcome the shortcomings of existing technology, current sprayers are fixed to grassland management workers by tying ropes or straps around them. This process is not only difficult and cumbersome, but the sprayers also easily fall off, causing great inconvenience to grassland management workers when spraying pesticides. This utility model proposes a portable sprayer for controlling locusts on grasslands.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A portable sprayer for controlling grassland locusts according to this utility model includes a spraying device. A fixing belt is fixedly connected to the front of the spraying device. A fixing block is fixedly connected to one end of the fixing belt. An elongated groove is opened inside the fixing block. The size of the elongated groove is adapted to the size of the fixing belt. A fixing mechanism is set inside the elongated groove. The fixing mechanism includes two sets of compression grooves. The two sets of compression grooves are opened at the top and bottom of the elongated groove. A locking block is set inside the compression groove. The side of the locking block near the compression groove is fixedly connected to one end of two sets of moving rods. The other end of the two sets of moving rods passes through the fixing block and is fixedly connected to a handle. A spring is sleeved on the outside of the moving rod. The two ends of the spring are fixedly connected to the locking block and the compression groove.
[0007] Preferably, the side of the card block away from the compression groove has a bevel, and the top and bottom of the fixing band away from the fixing block have multiple sets of card slots, and the size of the card block is adapted to the card slots.
[0008] Preferably, a buckle is fixedly connected to the outer side of the end of the fixing strap near the fixing block, and baffles are fixedly connected to the top and bottom of the end of the fixing strap away from the fixing block.
[0009] Preferably, a moving mechanism is provided at the front of the fixed block. The moving mechanism includes a moving groove, which is opened at the front of the fixed block. Screws are rotatably connected to both ends inside the moving groove. Moving blocks are threaded to the outer sides of both ends of the screws. A connecting block is fixedly connected to the front of the moving block. A limit groove is opened at the front of the handle, and a limit block is provided inside the limit groove. The limit block is fixedly connected to the connecting block.
[0010] Preferably, a limiting post is fixedly connected to the outer side of the middle part of the screw, and the threads at both ends of the screw are opposite.
[0011] Preferably, the movable block is inside the movable slot, and the size of the movable block is adapted to the movable slot.
[0012] Preferably, the top of the fixing block is provided with a hexagonal prism, and the output shaft of the hexagonal prism passes through the fixing block and is fixedly connected to the top of the screw.
[0013] The advantages of this utility model are:
[0014] 1. This utility model, through the structural design of the fixing mechanism, achieves the function of fixing by placing the fixing strap on the waist, inserting one end of the fixing strap with a slot into the slot inside the fixing block, and squeezing the block into the compression groove during the insertion of the fixing block into the slot. When the length of the fixing strap on the waist is appropriate, the appropriate slot is selected to align with the block. The block is squeezed into the compression groove, which compresses the spring. Therefore, when the slot and the block are aligned, the block springs into the slot, thus completing the fixing function of the fixing strap. This solves the problem that the current sprayer is fixed to the grassland management staff by tying ropes or straps, which is not only difficult and cumbersome to fix, but also easy to fall off the body, which makes it very inconvenient for grassland management staff to carry out pesticide spraying work.
[0015] 2. This utility model, through the structural design of the moving mechanism, realizes that the rotation of the hexagonal column drives the screw to rotate, thereby causing the moving blocks, connecting blocks, and limiting blocks at both ends of the screw to move towards each other. This ensures that the limiting block moves in the limiting groove opened at the front of the handle. When the limiting block is away from the fixed block in the limiting groove, the handle can be pulled normally, and the worker can put on and take off the fixing strap. After the worker has put on the fixing strap and spray device, the position of the limiting block is adjusted so that the limiting block is at the end of the limiting groove closer to the fixed block. In this way, the handle cannot be pulled, that is, the locking block cannot disengage from the locking groove and enter the compression groove. This solves the problem that when the worker has put on the fixing strap and spray device, accidentally touching the handle will cause the locking block to disengage from the locking groove, resulting in the fixing strap falling off.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0023] Please see Figure 1 - Figure 4 As shown, a portable sprayer for controlling locusts in grasslands includes a spraying device 1. A fixing strap 2 is fixedly connected to the front of the spraying device 1. A fixing block 3 is fixedly connected to one end of the fixing strap 2. A long groove 4 is opened inside the fixing block 3. The size of the long groove 4 is adapted to the size of the fixing strap 2. A fixing mechanism is set inside the long groove 4. The fixing mechanism includes two sets of compression grooves 5. The two sets of compression grooves 5 are opened at the top and bottom ends inside the long groove 4. A locking block 6 is set inside the compression groove 5. The side of the locking block 6 near the compression groove 5 is fixedly connected to one end of two sets of moving rods 7. The other end of the two sets of moving rods 7 passes through the fixing block 3 and is fixedly connected to a handle 8. A spring 9 is sleeved on the outside of the moving rod 7. The two ends of the spring 9 are fixedly connected to the locking block 6 and the compression groove 5.
[0024] During operation, the fixing strap 2 is placed around the waist, and one end of the fixing strap 2 with a slot 11 is inserted into the slot 11 inside the fixing block 3. During the insertion of the fixing block 3 into the slot 11, the locking block 6 is squeezed into the compression groove 5. When the length of the fixing strap 2 at the waist is appropriate, the appropriate slot 11 is selected to align with the locking block 6. The locking block 6 is squeezed into the compression groove 5, which compresses the spring 9. Therefore, when the slot 11 and the locking block 6 are aligned, the locking block 6 springs into the slot 11, thus completing the function of fixing the fixing strap 2. This solves the problem that the current sprayer is fixed to the grassland management staff by tying ropes or straps, which is not only difficult and cumbersome to fix, but also easy to fall off the body, which makes it very inconvenient for grassland management staff to carry out pesticide spraying.
[0025] Furthermore, such as Figure 2 As shown, the side of the card block 6 away from the compression groove 5 has a bevel 10, and the top and bottom of the fixing band 2 away from the fixing block 3 have multiple sets of card slots 11. The size of the card block 6 is adapted to the card slots 11.
[0026] During operation, the design of the beveled edge 10 of the card block 6 allows one end of the card slot 11 of the fixing band 2 to pass through the long groove 4. By pressing the beveled edge 10 on one side of the card block 6 through the top and bottom of the fixing band 2, the card block 6 can be squeezed into the compression groove 5. When the card slot 11 is aligned with the card block 6, the card block 6, which has been squeezed into the compression groove 5, is popped out into the card slot 11 by the spring 9. At this time, the fixing block 3 cannot be pulled out due to the design of the beveled edge 10, and can only continue to be pushed into the long groove 4.
[0027] Furthermore, such as Figure 3 As shown, a buckle 12 is fixedly connected to the outer side of the end of the fixing strap 2 near the fixing block 3, and baffles 13 are fixedly connected to the top and bottom of the end of the fixing strap 2 away from the fixing block 3.
[0028] During operation, when the worker fixes the spraying device 1 by passing the fixing strap 2 through the long groove 4, if the fixing strap 2 passing through the long groove 4 is long, it can be inserted into the buckle 12. The baffle 13 limits the maximum extent to which the fixing strap 2 can be inserted into the long groove 4. When the baffle 13 contacts the fixing block 3, the buckle 6 enters the last buckle 11 on the fixing strap 2, at which point the fixing strap 2 is tightened to the maximum.
[0029] Furthermore, such as Figure 4 As shown, a moving mechanism is provided at the front of the fixed block 3. The moving mechanism includes a moving groove 14, which is opened at the front of the fixed block 3. Screws 15 are rotatably connected to both ends inside the moving groove 14. Moving blocks 16 are threaded to the outer sides of both ends of the screws 15. A connecting block 17 is fixedly connected to the front of the moving block 16. A limit groove 18 is opened at the front of the handle 8. A limit block 19 is provided inside the limit groove 18. The limit block 19 is fixedly connected to the connecting block 17.
[0030] During operation, the rotation of the hexagonal column 21 drives the screw 15 to rotate, thereby causing the moving blocks 16, connecting blocks 17 and limiting blocks 19 at both ends of the screw 15 to move towards each other. This allows the limiting blocks 19 to move in the limiting groove 18 opened at the front of the handle 8. When the limiting blocks 19 are away from the fixed block 3 in the limiting groove 18, the handle 8 can be pulled normally. At this time, the operator can put on and take off the fixing strap 2. After the operator has put on the fixing strap 2 and the spray device 1, in order to prevent the fixing strap 2 from falling off due to accidental contact with the handle 8, the position of the limiting blocks 19 is adjusted so that the limiting blocks 19 are at the end of the limiting groove 18 closer to the fixed block 3. In this way, the handle 8 cannot be pulled, that is, the locking block 6 cannot disengage from the locking groove 11 and enter the compression groove 5.
[0031] Furthermore, such as Figure 4 As shown, a limit post 20 is fixedly connected to the outer side of the middle part of the screw 15, and the threads at both ends of the screw 15 are opposite.
[0032] During operation, the threads at both ends of the screw 15 are opposite, so when the screw 15 rotates, the two sets of moving blocks 16 at both ends of the screw 15 will move towards each other, thereby causing the connecting block 17 and the limiting block 19 to move towards each other. The limiting post 20 can restrict the movement position. When the moving block 16 contacts the limiting post 20, the limiting block 19 reaches the side of the limiting groove 18 close to the fixed block 3.
[0033] Furthermore, such as Figure 4 As shown, the movable block 16 is inside the movable slot 14, and the size of the movable block 16 is adapted to the movable slot 14;
[0034] During operation, the rotation of the screw 15 will cause the moving block 16 to have the same rotation tendency. Since the size of the moving block 16 is adapted to the moving groove 14, the rotation tendency of the moving block 16 will be hindered by the moving groove 14. Also, due to the threaded connection between the moving block 16 and the screw 15, the moving block 16 can move on the screw 15 as the screw 15 rotates.
[0035] Furthermore, such as Figure 2 As shown, a hexagonal post 21 is provided at the top of the fixing block 3, and the output shaft of the hexagonal post 21 passes through the fixing block 3 and is fixedly connected to the top of the screw 15;
[0036] During operation, the rotation of the hexagonal column 21 can drive the screw 15 to rotate. The shape of the hexagonal column 21 increases the static friction when the operator's hand rotates the hexagonal column 21, making it easier to rotate the hexagonal column 21.
[0037] Working principle: By placing the fixing strap 2 at the waist, one end of the fixing strap 2 with a slot 11 is inserted into the slot 11 inside the fixing block 3. During the insertion of the fixing block 3 into the slot 11, the locking block 6 is squeezed into the compression groove 5. When the length of the fixing strap 2 at the waist is appropriate, the appropriate slot 11 is aligned with the locking block 6. The locking block 6 is squeezed into the compression groove 5, which compresses the spring 9. Therefore, when the slot 11 and the locking block 6 are aligned, the locking block 6 springs into the slot 11 against the spring 9, thus completing the fixing of the fixing strap 2. The rotation of the hexagonal column 21 drives the screw 15 to rotate, thereby moving the two ends of the screw 15. The moving block 16, connecting block 17, and limiting block 19 move towards each other, so that the limiting block 19 moves in the limiting groove 18 opened at the front of the handle 8 to the end of the limiting groove 18 close to the fixed block 3. In this way, the handle 8 cannot be pulled, that is, the locking block 6 cannot disengage from the locking groove 11 and enter the compression groove 5. After the pesticide spraying work is completed, the hexagonal column 21 is rotated in the opposite direction so that the limiting block 19 moves in the limiting groove 18 opened at the front of the handle 8 to the end of the limiting groove 18 away from the fixed block 3. At this time, the locking block 6 can be pulled by pulling the two sets of handles 8 to enter the compression groove 5 and disengage from the locking groove 11, and then the disassembly of the fixing belt 2 is completed.
[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
