Description

Technical Field

[0001] This utility model belongs to the field of agricultural spraying equipment technology, specifically relating to a portable insecticide application tool. Background Technology

[0002] To ensure that forest vegetation is protected from pests and can grow healthily, pesticides are regularly sprayed on the vegetation to kill pests on crop plants. This effectively controls and reduces the number of pests on crops, protects plants from pest attacks, and thus ensures healthy growth, high and stable yields of crops, improves the quality and marketability of agricultural products, and increases farmers' economic income.

[0003] For example, Chinese Patent Publication No. CN214758787U discloses an agricultural insecticide atomizing spraying device, which includes a pesticide tank base. A rotating sleeve is provided at the bottom of the pesticide tank base. A threaded rod is provided on the upper side wall inside the rotating sleeve. A first bevel gear is sleeved on the upper side of the outer wall of the threaded rod. A second bevel gear is provided inside the rotating sleeve and corresponding to the first bevel gear. A rotating rod is provided on the side of the second bevel gear away from the first bevel gear. A turntable is provided at the end of the rotating rod away from the second bevel gear. A threaded sleeve support leg is sleeved on the outer wall of the threaded rod and below the first bevel gear. An electric pesticide tank is provided on the upper side of the pesticide tank base. The rotating sleeve and the pesticide tank base can rotate, so that the sleeve can be rotated out of the pesticide tank base when in use and rotated back to the pesticide tank base when not in use.

[0004] The above application still has shortcomings. The above application requires carrying the pesticide tank directly on the body with a shoulder strap, and the front is equipped with a spray bar. The spray direction of the spray head is manually controlled. Due to the difference in the height of the green plants and the need to spray different parts of the plants, the height of the spray head used by the insecticide spraying equipment needs to be adjusted frequently. Holding and adjusting the spray bar for a long time and carrying a heavy pesticide tank can easily cause fatigue. Spraying is relatively strenuous, the spray uniformity is insufficient, and the convenience and efficiency of spraying are poor.

[0005] Therefore, there is a need for a portable pesticide application tool to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to provide a portable insecticide application tool to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a portable insecticide application tool, comprising a base plate, a liquid storage tank, a delivery pump, and a support plate fixed to the top side of the base plate; a lead screw arranged along the height direction of the support plate on one side of the support plate, with both ends of the lead screw rotatably connected to the top of the support plate and the side wall of the base plate, respectively; a servo motor fixed to the top of the support plate, with the output end of the servo motor fixed to the top of the lead screw; a lead screw nut threadedly connected to the side of the lead screw; a guide groove arranged along the height direction of the support plate on the side of the support plate; and a guide groove fixed to the side of the lead screw nut. A guide groove slides and adapts to a protruding rod. A rotary adjustment assembly is provided at the end of the lead screw nut away from the protruding rod. A clamping assembly is connected to one end of the rotary adjustment assembly. A nozzle plate is fixed to one end of the rotary adjustment assembly via the clamping assembly. A connector tube is fixed to the bottom end of the nozzle plate. A liquid passage chamber communicating with the connector tube is opened inside the nozzle plate. A spray hole communicating with the liquid passage chamber is opened on the side of the nozzle plate. Multiple spray holes are provided and the multiple spray holes are evenly distributed. The input end of the delivery pump is connected to the inside of the liquid storage tank. A delivery hose is fixed to the output end of the delivery pump. The end of the delivery hose away from the delivery pump is connected to the connector tube.

[0008] It should be noted in the solution that the rotary adjustment assembly includes a rotating sleeve fixed to the end of the lead screw nut away from the lead screw, a shaft is rotatably connected inside the rotating sleeve, and a first locking bolt is threadedly connected to the side wall of the rotating sleeve, with the screw end of the first locking bolt contacting the side of the shaft.

[0009] It is further worth noting that the clamping assembly includes a clamp fixed to one end of the shaft, the connector tube is inserted into the clamp, and a second locking bolt is threaded onto one side wall of the clamp, with the screw end of the second locking bolt contacting the outer wall of the connector tube.

[0010] Furthermore, it should be noted that a protruding strip is fixed on the end of the shaft away from the clamp, and an indicator mark strip that cooperates with the protruding strip is provided on the end side of the rotating sleeve.

[0011] In a preferred embodiment, a diagonal rod is fixed to one end of the base plate. There are two diagonal rods, which are symmetrically distributed. A push handle is fixed to the top of both diagonal rods. A rubber sleeve is fitted onto the surface of the push handle.

[0012] In a preferred embodiment, the bottom end of the base plate is equipped with casters, and multiple casters are provided and the multiple casters are symmetrically distributed.

[0013] Compared with the prior art, the portable insecticide application tool provided by this utility model has at least the following beneficial effects:

[0014] (1) The servo motor drives the lead screw to rotate in both directions. The lead screw nut is guided and limited by the cooperation of the lead screw and the guide groove. The rotating lead screw drives the lead screw nut to move up and down. The lead screw nut drives the nozzle plate to move back and forth synchronously. This allows the insecticide liquid sprayed from the nozzle plate to be evenly sprayed on the entire plant, spraying the upper and lower surfaces of the leaves, the stems and the hard-to-reach hidden parts. This effectively improves the insecticidal effect and reduces the hiding space of pests. The up and down movement of the nozzle plate makes the spraying operation more efficient and convenient, and reduces the labor intensity of manual operation.

[0015] (2) The nozzle plate is clamped and fixed to the screw nut by the clamping assembly. The nozzle plate can be easily removed by the clamping assembly, which makes it convenient to clean and maintain the nozzle plate.

[0016] (3) When not in use, the nozzle plate clamped inside the clamping assembly can be flipped by the set adjustment component, so that the side with the spray hole on the nozzle plate faces down, thereby avoiding dust and impurities from falling into the spray hole and causing blockage and pollution.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Please see Figure 1-6This utility model provides a portable insecticide application tool, including a base plate 3. A liquid storage tank 4, a delivery pump 14, and a support plate 5 are fixed to the top side of the base plate 3. A lead screw 7 is arranged along the height direction of the support plate 5 on one side. The two ends of the lead screw 7 are rotatably connected to the top of the support plate 5 and the side wall of the base plate 3, respectively. A servo motor 6 is fixed to the top of the support plate 5, and the output end of the servo motor 6 is fixed to the top of the lead screw 7. A lead screw nut 15 is threaded onto the side of the lead screw 7. A guide groove 8 is formed along the height direction of the support plate 5 on the side of the support plate 5. A sliding contact that slides with the guide groove 8 is fixed to the side of the lead screw nut 15. The screw rod 9 and the lead screw nut 15 are equipped with a rotary adjustment assembly 1 at the end away from the screw rod 9. A clamping assembly 2 is connected to one end of the rotary adjustment assembly 1. A nozzle plate 10 is fixed to one end of the rotary adjustment assembly 1 via the clamping assembly 2. A connector pipe 19 is fixed to the bottom end of the nozzle plate 10. A liquid passage chamber 18 communicating with the connector pipe 19 is opened inside the nozzle plate 10. A spray hole 17 communicating with the liquid passage chamber 18 is opened on the side of the nozzle plate 10. Multiple spray holes 17 are provided and are equidistantly distributed. The input end of the delivery pump 14 is connected to the inside of the storage tank 4. An infusion hose 13 is fixed to the output end of the delivery pump 14. The infusion hose 13 is located away from the delivery point. One end of the pump 14 is connected to the connector pipe 19. A caster wheel 16 is installed at the bottom of the base plate 3. Multiple caster wheels 16 are arranged symmetrically. During use, the storage tank 4 contains insecticide liquid. The multiple caster wheels 16 allow the entire device to move. During this process, the servo motor 6 and the pump 14 are activated. The pump 14 delivers the insecticide liquid from the storage tank 4 through the delivery hose 13 and connector pipe 19 to the nozzle plate 10. The insecticide liquid is then evenly and finely sprayed onto the plants through the liquid passage chamber 18 and multiple spray holes 17 for insect control. Simultaneously, the servo motor... The machine 6 drives the lead screw 7 to rotate in both directions. The lead screw nut 15 is guided and limited by the cooperation of the convex rod 9 and the guide groove 8. The rotating lead screw 7 drives the lead screw nut 15 to move up and down, which in turn drives the nozzle plate 10 to move back and forth synchronously. This allows the insecticide liquid sprayed by the nozzle plate 10 to be evenly sprayed on the entire plant, the upper and lower surfaces of the leaves, the stems, and hard-to-reach hidden parts. This effectively improves the insecticidal effect, reduces the hiding space of pests, and the up and down movement of the nozzle plate 10 makes the spraying operation more efficient and convenient, reducing the labor intensity of manual operation.The nozzle plate 10 is clamped and fixed to the lead screw nut 15 by the clamping assembly 2. The nozzle plate 10 can be easily removed by the clamping assembly 2, making it convenient for cleaning and maintenance. When not in use, the nozzle plate 10 clamped inside the clamping assembly 2 can be flipped by the rotating assembly 1, so that the side of the nozzle plate 10 with the spray holes 17 faces downward, thus preventing dust and impurities from falling into the spray holes 17 and causing blockage and pollution.

[0026] Further as Figure 3 and Figure 5 As shown, it is worth noting that the rotary adjustment assembly 1 includes a rotating sleeve 101 fixed to the end of the lead screw nut 15 away from the protruding rod 9. A shaft 105 is rotatably connected inside the rotating sleeve 101. A first locking bolt 104 is threaded onto the side wall of the rotating sleeve 101, and the screw end of the first locking bolt 104 contacts the side of the shaft 105. During normal use, by tightening the first locking bolt 104, the shaft 105 is locked inside the rotating sleeve 101. At this time, the liquid is discharged through the spray hole 1 on the nozzle plate 10. 7. Spray insecticide liquid onto the plant by facing the side of the base plate 3. When not in use, loosen the first locking bolt 104 to release the shaft 105 from the rotating sleeve 101, thereby rotating and adjusting the shaft 105. This allows the nozzle plate 10 clamped inside the clamping assembly 2 to be flipped so that the side of the nozzle plate 10 with the spray hole 17 faces down, thus preventing dust and impurities from falling into the spray hole 17 and causing blockage and pollution. This makes it easier to use and improves the service life of the nozzle plate 10.

[0027] Further as Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, it is worth noting that the clamping assembly 2 includes a clamping seat 201 fixed to one end of the shaft 105, and a connector tube 19 inserted into the clamping seat 201. A second locking bolt 202 is threaded onto one side wall of the clamping seat 201, and the screw end of the second locking bolt 202 contacts the outer side wall of the connector tube 19. In actual operation, the connector tube 19 at the bottom of the nozzle plate 10 is inserted into the clamping seat 201, and the connector tube 19 is clamped and fixed by tightening the second locking bolt 202, that is, the nozzle plate 10 is clamped and fixed onto the screw nut 15.

[0028] This solution has the following working process: Multiple casters 16 allow the entire device to move. A delivery pump 14 pumps the insecticide liquid from the storage tank 4 through the delivery hose 13 and connector 19 to the nozzle plate 10. The insecticide liquid is then evenly and finely sprayed onto the plants through the liquid passage chamber 18 and multiple spray holes 17 for insect control. Simultaneously, a servo motor 6 drives the lead screw 7 to rotate reciprocally in both directions. The lead screw nut 15 is guided and limited by the cooperation of the convex rod 9 and the guide groove 8. Thus, the rotating lead screw 7 drives the lead screw nut 15 to move up and down reciprocally, thereby achieving the desired effect. The screw nut 15 drives the nozzle plate 10 to move synchronously back and forth, so that the insecticide liquid sprayed by the nozzle plate 10 can be evenly sprayed onto the entire plant, onto the upper and lower surfaces of the leaves, the stem, and hard-to-reach hidden parts. When not in use, by loosening the first locking bolt 104, the shaft 105 is released from being fixed in the rotating sleeve 101, so that the adjusting shaft 105 can be rotated, and the nozzle plate 10 clamped inside the clamp 201 can be flipped so that the side of the nozzle plate 10 with the spray hole 17 faces down, thereby preventing dust and impurities from falling into the spray hole 17 and causing blockage and pollution.

[0029] Further as Figure 5 As shown, it is worth noting that a protrusion 102 is fixed on the end of the shaft 105 away from the clamp 201, and an indicator mark 103 that cooperates with the protrusion 102 is provided on the end side of the rotating sleeve 101. In actual operation, the protrusion 102 and the indicator mark 103 cooperate to assist the nozzle plate 10 in rotating into place, so as to avoid the nozzle plate 10 from tilting.

[0030] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that a diagonal rod 11 is fixed on one end of the base plate 3. There are two diagonal rods 11, and the two diagonal rods 11 are symmetrically distributed. The top of the two diagonal rods 11 are fixed together with a push handle 12. The surface of the push handle 12 is fitted with a rubber sleeve. In actual operation, the push handle 12 can be used to easily push the whole device to move and spray insecticide liquid, which is convenient for operation.

[0031] In summary: The servo motor 6 drives the lead screw 7 to rotate in both directions. The lead screw nut 15 is guided and limited by the cooperation of the convex rod 9 and the guide groove 8. The rotating lead screw 7 drives the lead screw nut 15 to move up and down, which in turn drives the spray nozzle plate 10 to move synchronously. This ensures that the insecticide liquid sprayed from the spray nozzle plate 10 is evenly sprayed onto the entire plant, covering the upper and lower surfaces of the leaves, stems, and hard-to-reach hidden areas. This effectively improves the insecticidal effect and reduces the hiding space for pests. The nozzle plate 10 makes spraying operations more efficient and convenient, reducing the labor intensity of manual operation. The nozzle plate 10 is clamped and fixed to the screw nut 15 by the clamping component 2. The nozzle plate 10 can be easily removed by the clamping component 2, which facilitates cleaning and maintenance of the nozzle plate 10. When not in use, the nozzle plate 10 clamped in the clamping component 2 can be flipped by the rotating component 1, so that the side with the spray hole 17 on the nozzle plate 10 faces down, thereby avoiding the problem of dust and impurities falling into the spray hole 17 and causing blockage and pollution.

[0032] The servo motor 6 and the delivery pump 14 can be purchased commercially. The servo motor 6 and the delivery pump 14 are equipped with power supplies. They are mature technologies in the field and have been fully disclosed. Therefore, they will not be described again in the specification.
