A cart-type sprayer

Abstract

This invention discloses a trolley-type sprayer, relating to the field of spraying equipment technology. By setting up a flow-stabilizing liquid suction component, utilizing a protective sleeve, two liquid inlet channels arranged in different directions, and a grid plate and spiral flow channel plate inside the suction pipe, the liquid undergoes deceleration, diversion, and flow equalization before entering the suction pipe. This reduces the generation of eddies and bubbles, improves suction stability and spray uniformity. Furthermore, a buffer baffle and a through-hole are installed in the liquid storage chamber, creating a step-by-step buffered flow structure within the chamber. During movement or bumping of the trolley-type sprayer, the liquid flow is transformed from overall swaying to zoned buffered flow, effectively reducing liquid impact and fluctuation, preventing air pockets in the suction area, and improving the stability of the suction process.

Description

Technical Field

[0001] This invention relates to the field of spray equipment technology, specifically a cart-type sprayer. Background Technology

[0002] Wheeled sprayers, a common type of liquid spraying equipment, are widely used in agricultural plant protection, landscaping, and cleaning and disinfection. They store liquid in a storage tank and use a pumping system to deliver the liquid to the spraying end for spraying operations. Current wheeled sprayers have a relatively simple structure, and the storage tank typically lacks effective control measures for liquid flow, especially when the equipment is moving or the ground is uneven, causing significant sloshing and impact of the liquid within the tank.

[0003] During the above-mentioned use, the violent fluctuations of the liquid can easily lead to local instability of the liquid level at the suction end, or even temporary exposure to air. This causes the suction pipe to draw in air during operation, generating bubbles. At the same time, due to the turbulent flow during the suction process, the liquid is also prone to forming a vortex structure, which further exacerbates the generation and entry of bubbles. After these bubbles enter the pumping system, they will not only affect the continuity and stability of liquid delivery, but also reduce the uniformity of spraying, and in severe cases, even affect the normal operating performance of the equipment. Summary of the Invention

[0004] To address the problems of existing trolley-type sprayers, such as liquid shaking and impact during movement, unstable liquid absorption, easy inhalation of air bubbles, and incompletely dissolved particles entering the liquid absorption system and causing blockage, this invention provides a trolley-type sprayer.

[0005] This invention is achieved through the following technical solution: a trolley-type sprayer, including a main support frame, wherein a liquid storage system is provided on the main support frame;

[0006] The liquid storage system includes an irregularly shaped stepped liquid storage tank and a liquid storage cavity. The irregularly shaped stepped liquid storage tank is installed inside the main load-bearing frame. The liquid storage cavity is opened inside the irregularly shaped stepped liquid storage tank. A buffer baffle is installed inside the liquid storage cavity. Several through holes are opened on the buffer baffle to make the liquid storage cavity form a buffer flow structure. A turbulence mixing component and a flow stabilizing liquid absorption component are installed inside the irregularly shaped stepped liquid storage tank.

[0007] The steady-flow liquid suction assembly is located at the bottom of the liquid storage chamber. A liquid collection trough is provided at the lowest point of the bottom of the liquid storage chamber. A protective sleeve is installed at the lowest point of the bottom of the liquid storage chamber. A water suction pipe is provided inside the irregular stepped liquid storage tank. Several liquid inlet grooves 1 and 2 are provided on the outer surface of the protective sleeve. A liquid suction protective tube is installed on one end surface of the water suction pipe. Several liquid inlet grooves 3 are evenly distributed on the bottom surface of the liquid suction protective tube. A grid plate for diverting the flow and a spiral flow channel plate for guiding the flow are provided inside the liquid suction protective tube so that the liquid enters the water suction pipe after being decelerated and evenly distributed.

[0008] Furthermore, the turbulence mixing component is disposed on the top of the irregularly shaped stepped liquid storage tank. The turbulence mixing component includes a tank cover and a retaining plate. The top surface of the irregularly shaped stepped liquid storage tank is threadedly connected to the tank cover, and the top surface of the tank cover is fitted with a retaining plate. A bearing sleeve is installed inside the retaining plate.

[0009] Furthermore, a handle wheel is installed inside the bearing sleeve, and a turbine is bolted to the outer surface of the handle wheel. Several conical spikes are provided on the outer surface of the handle wheel. A partition plate is installed on the inner surface of the irregular stepped liquid storage tank. Several through holes are provided on the partition plate. The partition plate is used to divide the liquid in the storage chamber into areas and to block undissolved solid particles, so as to prevent undissolved particles from entering the flow stabilizing liquid suction component at the bottom of the storage chamber, thereby avoiding blockage of the water suction pipe.

[0010] Furthermore, the outer surface of the main load-bearing frame is equipped with a traveling wheel, the outer surface of the main load-bearing frame is equipped with a support foot, the top surface of the main load-bearing frame is equipped with a power system, the outer surface of the power system is equipped with a pumping system, and one end of the pumping system is fixedly connected to one end of the water suction pipe.

[0011] Furthermore, a reel spraying system is installed on the other end surface of the pumping system, and a liquid level assembly is installed on the outer surface of the irregular stepped liquid storage tank.

[0012] Furthermore, the liquid level assembly includes a liquid level tube and a float. The liquid level tube is installed on the outer surface of the irregular stepped liquid storage tank, and the float is movably installed inside the liquid level tube.

[0013] Furthermore, the first liquid inlet tank is inclined and the second liquid inlet tank is horizontal, so that the liquid entering the protective sleeve forms flow paths in different directions, thereby reducing interference with the liquid inlet process of the third liquid inlet tank at the bottom of the suction tube.

[0014] Furthermore, the diameter of the second through-hole is smaller than the particle size of the undissolved solid particles.

[0015] Furthermore, a drain pipe is installed at the bottom of the irregularly shaped stepped liquid storage tank, a locking block is installed on the outer surface of the irregularly shaped stepped liquid storage tank, a liquid storage tank is movably installed on the outer surface of the locking block, a locking groove is opened on the outer surface of the liquid storage tank, and the inner wall of the locking groove is in movable contact with the outer surface of the locking block.

[0016] The present invention has the following beneficial effects:

[0017] (1) The trolley sprayer, by setting a steady flow suction component, utilizes a protective sleeve, a liquid inlet trough one and a liquid inlet trough two set in different directions, and a grid plate and a spiral flow channel plate inside the suction pipe to slow down, divert and equalize the liquid before it enters the suction pipe, thereby reducing the generation of eddies and bubbles, and improving the suction stability and spray uniformity.

[0018] (2) The trolley sprayer, by setting a buffer partition and a through hole in the liquid storage chamber, makes the liquid form a step-by-step buffer flow structure in the liquid storage chamber. During the movement or bumping of the trolley sprayer, the liquid can be changed from overall shaking to zoned buffer flow, thereby effectively reducing liquid impact and fluctuation, avoiding the phenomenon of vacuuming in the water absorption area, and improving the stability of the liquid absorption process.

[0019] (3) The trolley sprayer, by setting up a partition plate and two through holes, divides the liquid in the storage chamber into areas and blocks the undissolved solid particles, making it difficult for them to enter the liquid absorption area at the bottom of the storage chamber, thereby effectively preventing the water absorption pipe from getting blocked and improving the reliability and continuous operation capability of the device.

[0020] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0033] Please see Figures 1-9 The present invention provides a technical solution: a trolley sprayer, including a main support frame 1, on which a liquid storage system 2 is provided;

[0034] The liquid storage system 2 includes an irregularly shaped stepped liquid storage tank 201 and a liquid storage chamber 205. The irregularly shaped stepped liquid storage tank 201 is installed inside the main load-bearing frame 1. The irregularly shaped stepped liquid storage tank 201 has a liquid storage chamber 205 inside. A buffer baffle 206 is provided inside the liquid storage chamber 205. Several through holes 207 are provided on the buffer baffle 206 so that the liquid storage chamber 205 forms a buffer flow structure. The irregularly shaped stepped liquid storage tank 201 is equipped with a turbulence mixing component 3 and a flow stabilizing liquid absorption component 4.

[0035] A steady-flow liquid suction assembly 4 is located at the bottom of the liquid storage chamber 205. A liquid collection trough 404 is provided at the lowest point of the bottom of the liquid storage chamber 205. A protective sleeve 401 is installed at the lowest point of the bottom of the liquid storage chamber 205. A water suction pipe 405 is provided inside the irregularly shaped stepped liquid storage tank 201. Several liquid inlet grooves 402 and several liquid inlet grooves 403 are provided on the outer surface of the protective sleeve 401. A liquid suction protective tube 409 is installed on one end of the water suction pipe 405. Several liquid suction protective tubes are evenly distributed on the bottom surface of the liquid suction protective tube 409. The liquid inlet tank 406 and the liquid suction pipe 409 are equipped with a grid plate 407 for diversion and a spiral flow channel plate 408 for guiding the flow, so that the liquid enters the suction pipe 405 after being decelerated and evenly distributed. The irregular stepped liquid storage tank 201 and the liquid storage cavity 205 are used to contain the liquid. The buffer baffle 206 and the through hole 207 are used to realize the liquid graded buffer flow and reduce sloshing. The steady flow suction component 4 is used to decelerate and evenly distribute the suction liquid, so that the liquid enters the suction pipe 405 stably.

[0036] The turbulence mixing component 3 is disposed on the top of the irregular stepped liquid storage tank 201. The turbulence mixing component 3 includes a tank cover 301 and a retaining plate 304. The tank cover 301 is threadedly connected to the top surface of the irregular stepped liquid storage tank 201. The retaining plate 304 is installed on the top surface of the tank cover 301. A bearing sleeve 302 is installed inside the retaining plate 304. The tank cover 301 is used to seal the irregular stepped liquid storage tank 201, and the retaining plate 304 is used to fix the structure. The bearing sleeve 302 is used to support the stable rotation of the handle wheel 303.

[0037] A handle wheel 303 is installed inside the bearing sleeve 302. A turbine 305 is bolted to the outer surface of the handle wheel 303. Several conical spikes 306 are provided on the outer surface of the handle wheel 303. A partition plate 307 is installed on the inner surface of the irregular stepped liquid storage tank 201. Several through holes 308 are provided on the partition plate 307. The partition plate 307 is used to divide the liquid in the liquid storage chamber 205 into areas and to block undissolved solid particles to prevent undissolved particles from entering the flow stabilizing liquid suction component 4 at the bottom of the liquid storage chamber 205, thereby avoiding blockage of the water suction pipe 405. The handle wheel 303 drives the turbine 305 and the conical spikes 306 to agitate and mix the liquid. The partition plate 307 and the through holes 308 are used to separate the liquid and block undissolved particles to prevent them from entering the water suction pipe 405 and causing blockage.

[0038] The outer surface of the main support frame 1 is equipped with a traveling wheel 101 and a support foot 102. The top surface of the main support frame 1 is equipped with a power system 103 and a pumping system 104 is equipped with a pumping system 104. One end of the pumping system 104 is fixedly connected to one end of the suction pipe 405. The traveling wheel 101 is used for equipment movement, and the support foot 102 is used for stable support. The power system 103 drives the pumping system 104 to realize liquid suction and transportation.

[0039] A reel spraying system 105 is installed on the other end surface of the pumping system 104, and a liquid level component 5 is installed on the outer surface of the irregular stepped liquid storage tank 201. The reel spraying system 105 is used for liquid spraying, and the liquid level component 5 is used to display the liquid storage volume.

[0040] The liquid level assembly 5 includes a liquid level tube 501 and a float 502. The liquid level tube 501 is installed on the outer surface of the irregular stepped liquid storage tank 201, and the float 502 is movably installed inside the liquid level tube 501. The liquid level tube 501 is used to display the liquid level height, and the float 502 is used to indicate changes in the liquid level.

[0041] The first liquid inlet 402 is inclined and the second liquid inlet 403 is horizontal, so that the liquid entering the protective sleeve 401 forms different flow paths, thereby reducing the interference with the liquid inlet process of the third liquid inlet 406 at the bottom of the suction tube 409. The first liquid inlet 402 and the second liquid inlet 403 are used to guide the liquid to enter from multiple directions and reduce the interference with the liquid inlet of the suction tube 409.

[0042] The aperture of through hole 308 is smaller than the particle size of undissolved solid particles. Through hole 308 is used to restrict the passage of particles and prevent undissolved particles from entering the steady flow liquid absorption assembly 4.

[0043] The bottom of the irregular stepped liquid storage tank 201 is equipped with a drain pipe 208. A locking block 204 is installed on the outer surface of the irregular stepped liquid storage tank 201. A liquid storage tank 202 is movably installed on the outer surface of the locking block 204. A locking groove 203 is opened on the outer surface of the liquid storage tank 202. The inner wall of the locking groove 203 is in contact with the outer surface of the locking block 204. The drain pipe 208 is used for draining liquid. The locking block 204 cooperates with the locking groove 203 to realize the quick assembly and disassembly of the liquid storage tank 202.

[0044] The specific working process of this invention is as follows: When in use, this trolley sprayer is supported as a whole by the main load-bearing frame 1, and the trolley sprayer is moved by the walking wheels 101. The support feet 102 provide stable support during operation.

[0045] Before operation, the liquid is added to the storage chamber 205 inside the irregular stepped liquid storage tank 201 through the liquid storage system 2. If it is necessary to replenish or replace the liquid, the liquid storage tank 202 can be used to place the replenishing liquid. The liquid supply can be assisted by the liquid storage tank 202 set on the outside of the irregular stepped liquid storage tank 201. The liquid storage tank 202 can be quickly disassembled and assembled by the cooperation of the slot 203 and the block 204, thereby improving the efficiency of liquid addition and replacement.

[0046] After the liquid enters the storage chamber 205, it is mixed by the turbulence mixing component 3. First, the tank cover 301 is screwed on, and the operator turns the handle wheel 303. The handle wheel 303 rotates stably in the bearing sleeve 302, driving the turbine 305 and several conical spikes 306 to rotate within the storage chamber 205, thereby agitating the liquid and accelerating the dissolution and mixing of the agent. At the same time, the partition plate 307 divides the storage chamber 205 into zones, and the liquid flows slowly through the second through hole 308, allowing for the mixing of any insufficiently dissolved components during the liquid flow. Solid particles are blocked to prevent them from flowing downwards into the bottom of the liquid storage chamber 205. Under the action of gravity, the mixed liquid flows through the stepped structure of the irregular stepped liquid storage tank 201 and the through hole 207 on the buffer baffle 206 in stages, and the flow rate gradually decreases. Finally, it is collected in the liquid collection tank 404 at the lowest point of the bottom of the liquid storage chamber 205, realizing the directional concentration of the liquid. When the trolley sprayer moves or bumps, the buffer baffle 206 and the through hole 207 change the liquid from overall shaking to zoned buffer flow, thereby suppressing liquid impact and fluctuation.

[0047] During the spraying operation, the power system 103 drives the pumping system 104 to operate, drawing liquid from the bottom of the storage chamber 205 through the suction pipe 405. During the suction process, the liquid first enters the outside of the protective sleeve 401, and then enters the inside of the protective sleeve 401 through inlet groove one 402 and inlet groove two 403 respectively. Inlet groove one 402 is inclined, while inlet groove two 403 is horizontal, creating different flow paths for the entering liquid, thereby reducing impact interference between liquid flows. Subsequently, the liquid enters the suction protective pipe 409 through inlet groove three 406 evenly distributed at the bottom. During entry, the liquid is first diverted by the grid plate 407, and then... Under the guiding effect of the spiral flow channel plate 408, a slow flow is formed, thereby decelerating and equalizing the flow of the liquid, reducing the generation of eddies and bubbles, and allowing the liquid to enter the suction pipe 405 stably. Finally, the liquid is transported to the pumping system 104 through the suction pipe 405, and after being pressurized, it enters the reel spraying system 105 and is atomized and sprayed out through the nozzle to realize the spraying operation. At the same time, through the liquid level component 5 set on the outside of the irregular stepped liquid storage tank 201, the float 502 in the liquid level tube 501 moves up and down with the liquid level change, thereby realizing the intuitive display of the liquid level, which makes it easy for operators to grasp the liquid balance. When it is necessary to empty or clean the equipment, the liquid can be discharged through the drain pipe 208 set at the bottom of the liquid storage tank.
