Description

Technical Field

[0001] This utility model belongs to the field of spraying device technology, specifically relating to a herbicide spraying cart. Background Technology

[0002] In agricultural technology, herbicides are widely used to manage weed growth. They need to be used in conjunction with spraying equipment. Currently, the most widely used spraying equipment is of two types: manual sprayers and mechanized sprayers. Manual sprayers are carried on the back of the operator, who presses a lever with one hand to generate pressure and holds the nozzle with the other hand to spray the crops. Manual spraying is tiring and the spray is uneven, but its advantage is that it is easy to control. The other type is mechanized spraying devices, such as the forestry chemical herbicide spraying device provided in CN211881881. However, existing mechanized spraying devices have a relatively complex structure and can only spray according to a pre-set program, which is not flexible enough and does not have the function of adjusting the spray pressure.

[0003] Therefore, based on the problems of existing spraying devices, it is necessary to propose a spraying device that combines the advantages of the two methods mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide a herbicide spraying cart, which aims to solve the problems of small spraying range and low uniformity in existing herbicide spraying devices.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A herbicide spraying cart includes a cart body with a pair of handles at one end; a liquid supply assembly mounted on the cart body; a spray nozzle mounted on the cart body with its inlet connected to the outlet of the liquid supply assembly; and an electrical control box mounted on the cart body. The liquid supply assembly has a built-in main solenoid valve and a pressure regulating valve for controlling water pressure. The electrical control box is electrically connected to the main solenoid valve and the pressure regulating valve. Each handle is equipped with a control switch, and the two control switches are respectively electrically connected to the electrical control box to control the main solenoid valve and the pressure regulating valve.

[0007] The beneficial effects of this utility model are: it provides a herbicide spraying cart, on which a liquid supply component, a spraying component, and an electrical control box are installed in sequence. The overall switch and water pressure are controlled by two control switches on the handle. Compared with traditional mechanized spraying devices, it is more flexible and less labor-intensive than purely manual backpack spraying devices. Moreover, it is easy to operate. By placing the control switches on the handle, the operator can complete the spraying while pushing the cart and control the spray pressure without any other large movements.

[0008] Furthermore, the liquid supply assembly includes a liquid storage tank, a pump body, and multiple delivery pipes. There are multiple liquid storage tanks, all of which are fixedly installed on the vehicle body. The multiple liquid storage tanks are respectively connected to the pump body through the delivery pipes. The pump body is connected to the spray nozzle through the delivery pipes. The main solenoid valve is located at the liquid inlet end of the pump body, and the pressure regulating valve is located at the liquid outlet end of the pump body.

[0009] A further beneficial effect of this invention is that by setting up multiple liquid storage tanks, different types or concentrations of herbicides can be stored on the same spraying cart.

[0010] Furthermore, each of the liquid storage tanks has a built-in stirring mechanism, and the drive motor of the stirring mechanism is electrically connected to the electrical control box.

[0011] A further beneficial effect of this utility model is that the built-in stirring mechanism in the storage tank can ensure that the pesticide in the storage tank is always in a mixed state during the spraying operation, preventing the pesticide in the tank from settling and affecting the weeding effect.

[0012] Furthermore, each of the liquid storage tanks includes a tank body, a drive motor, a stirring shaft, stirring blades, and a liquid inlet channel. The tank body is fixedly connected to the vehicle body; the drive motor is fixedly connected to the top of the tank body; the stirring shaft is vertically arranged inside the tank body and is connected to the motor shaft of the drive motor; there are multiple stirring blades, which are sequentially fixedly connected to the stirring shaft along its length; the liquid inlet channel is inclined and connects to the top of the tank body to avoid the drive motor.

[0013] A further beneficial effect of this utility model is that it specifically defines the structure and positional installation relationship of the stirring mechanism, and the inclined liquid inlet channel can avoid the drive motor.

[0014] Furthermore, it also includes a sprayer mounting assembly, which includes a drive box, a drive shaft, and a clamping member. The drive box is fixedly connected to the other end of the vehicle body relative to the handle. The drive shaft is arranged vertically, and its lower end is connected to the drive end of the drive box. The mounting end of the clamping member is fixedly connected to the upper end of the drive shaft, and the clamping end is detachably connected to the sprayer.

[0015] A further beneficial effect of this invention is that by using the drive unit in conjunction with the transmission shaft and the clamping parts to assist in adjusting the spray direction of the sprayer, a larger spray width can be obtained.

[0016] Furthermore, the clamping component includes a support platform, a fixing plate, and spring pillars. The support platform is horizontally arranged, with its lower end fixedly connected to the upper end of the drive shaft. There are two fixing plates, arranged opposite each other and perpendicular to and fixedly connected to the upper end of the support platform. There are two spring pillars, one end of which is fixedly connected to the opposite side of the two fixing plates, and the other end is coaxially arranged.

[0017] A further beneficial effect of this utility model is that by setting the clamping end of the clamping member as an elastic structure, the sprayer body is protected and its wear is reduced.

[0018] Furthermore, the spray nozzle includes an input section, a main pipe, a first branch pipe, a second branch pipe, a first output section, and a second output section. One end of the input section is connected to the outlet end of the liquid supply assembly, and the other end is connected to the middle part of the main pipe. The first ends of the first branch pipe and the second branch pipe are perpendicular to and connected to both ends of the main pipe, respectively. The first output section and the second output section are connected to the second ends of the first branch pipe and the second branch pipe, respectively.

[0019] A further beneficial effect of this utility model is that it provides a dual-nozzle sprayer. The arrangement of the first branch pipe and the second end of the second branch pipe allows the liquid flowing out from the two branch pipes to have a height difference in space. When the sprayer is started, the upper branch pipe, in conjunction with the output part, can spray to a farther position, while the lower branch pipe, in conjunction with the output part, can cover the nearby position. On the one hand, it is not necessary to raise the spray angle to increase the head, and on the other hand, it can reduce the spray dead angle at the near position formed by the shortest spray distance of traditional sprayers.

[0020] Furthermore, the main pipe, the first branch pipe, and the second branch pipe are integrally formed, the main pipe, the first branch pipe, and the second branch pipe have the same diameter, and the lengths of the first branch pipe and the second branch pipe are shorter than that of the main pipe.

[0021] Further beneficial effects of this utility model are: the same pipe diameter can ensure the stability of the liquid pressure inside the spray nozzle, and the integral molding of the main pipe and branch pipe can solve the problem of the spray nozzle structure, preventing leakage and seepage.

[0022] Furthermore, the first output section includes a connector, a one-way throttle valve, and a nozzle connected coaxially in sequence. The inlet end of the connector is detachably connected to the second end of the first branch pipe. The structure of the second output section is the same as that of the first output section.

[0023] A further beneficial effect of this utility model is that the direction of liquid ejection is limited by the liquid flow direction inside the connector, and the flow rate of the ejected liquid is controlled by a one-way throttle valve in conjunction with the nozzle.

[0024] Furthermore, the output directions formed by the first output section and the second output section expand outward along both sides of the input section, respectively.

[0025] A further beneficial effect of this invention is that by setting the output directions of the first and second connectors to expand outwards along both sides of the input section, the sprayer only needs to oscillate within a small range in the horizontal direction to obtain a larger spray width, thereby improving spraying efficiency and spray uniformity.

[0044] 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 protection scope of the present utility model.

[0045] As shown in the figure, this utility model provides a herbicide spraying cart, including a cart body 2, a liquid supply component 3, a spray nozzle 1, and an electrical control box 4. The cart body 2 is a flatbed cart with four casters at the bottom and two handles 201 at one end. A protective plate is installed between the two handles. When the operator operates the cart to spray pesticides, the protective plate is located directly in front of the operator to effectively prevent the pesticide from splashing onto the operator. The liquid supply component 3 is installed on the cart body 2, the spraying component is installed on the cart body 2, and the spray nozzle 1 is mounted on the cart body 2 and connected to the liquid supply component 3. The electrical control box 4 is installed on the cart body 2. The liquid supply component 3 has a built-in main solenoid valve and a pressure regulating valve for controlling water pressure. The electrical control box 4 is electrically connected to the main solenoid valve and the pressure regulating valve. Control switches 202 are installed on the two handles 201 respectively. The control switches 202 are electrically connected to the electrical control box 4. The control switch 202 on one handle 201 is used to control the main solenoid valve, and the control switch 202 on the other handle is used to control the pressure regulating valve.

[0046] The herbicide spraying cart provided in this embodiment has a main solenoid valve for starting the device, a pressure regulating valve for controlling and regulating water pressure, and control switches 202 installed on the left and right handles 201 of the cart. The control switches 202 are electrically connected to the electrical control box 4 to transmit commands. When the operator operates the cart 2 to spray herbicide, they only need to hold the handles 201 with both hands to push the cart 2 to move. Spraying and adjusting the spray pressure can be done by pressing the control switch with the thumb, which is very convenient to operate.

[0047] In some embodiments, the liquid supply assembly 3 includes multiple storage tanks 310, a pump body 320, and multiple delivery pipes 330. The multiple storage tanks 310 can store different types and concentrations of herbicides. Each storage tank 310 includes a tank body 311, the lower end of which is mounted on the vehicle body 2 via a multi-leg bracket. A stirring motor 312 is located at the top, and a stirring shaft 313 and stirring blades 314 are installed inside to ensure uniform distribution of the herbicide within the storage tank 310. A dosing port 315 extends outwards at the top, a method primarily used to avoid obstructing the storage tank. The stirring shaft 313 inside the liquid tank 310 and the stirring motor 314 at the top have an openable and closable medicine outlet 316 at the center of the lower end for connecting to the delivery pipe 330. An electric control switch is installed at the medicine outlet 316, and the electric control switch is electrically connected to the electric control box 4. The number of pump bodies 320 and sprayers 1 corresponds to the number of liquid storage tanks 310. The pump body 320 connects the liquid storage tank 310 and the sprayer 1 through the delivery pipe 330. The main solenoid valve and the pressure regulating valve are installed on the pump body 320. Multiple switches are also provided to control the main solenoid valve and the pressure regulating valve, and they are controlled separately.

[0048] In addition, to prevent the liquid sprayed from adjacent sprayers 1 from interfering with each other, a baffle is installed between two adjacent sprayers 1.

[0049] In some embodiments, a sprayer mounting assembly 5 is also included. The sprayer mounting assembly 5 is arranged at the other end of the vehicle body 2 relative to the handle 201. It includes a drive unit 510, a drive shaft 520, and a clamping member 530. The drive unit 510 has a square housing and is fixedly mounted on the vehicle body. A small motor and a swing mechanism are installed inside. The lower end of the drive shaft 520 is connected to the swing end of the swing mechanism. The swing mechanism can drive the drive shaft 520 to swing slightly. The swing mechanism itself is a common mechanism in the mechanical field and is also a conventional technical means in the field of spraying devices, so it will not be described in detail here. The clamping member 530 is installed at the upper end of the drive shaft 520 and is used to clamp the input part 110 of the sprayer 1. Under the clamping of the clamping member 530, the output part 110 and the first plane V1 are kept horizontal, and the sprayer 1 swings back and forth slightly with the drive shaft 520, which can further increase the spray width.

[0050] In some embodiments, the clamping member 530 includes a support platform 531, a fixing plate 532, and spring posts 533. The support platform 531 is horizontally arranged, and its lower end is fixedly connected to the upper end of the drive shaft 520. There are two fixing plates 532, which are arranged opposite to each other and are perpendicular to the upper surface of the support platform 531 and are slidably connected along the platform surface of the support platform 531. They can move closer to each other and further away from each other. There are two spring posts 533, which are movably mounted on the opposite surfaces of the two fixing plates 532. The ends of the two spring posts 533 are arranged opposite to each other for fixing the input part 110 of the sprayer 1. The ends of the spring posts 533 have grooves that are adapted to the shape of the input part 110 to ensure the stability of the clamping. The spring posts 533 themselves can also reduce the wear of the input part 110 during the clamping process.

[0051] In some embodiments, the spray nozzle 1 includes an input section 110, a main pipe 120, a first branch pipe 130, a second branch pipe 140, a first output section 150, and a second output section 160. One end of the input section 110 is connected to an external liquid source and the liquid inflow direction is D1. The other end is connected to the middle of the main pipe 120. D1 and the axis of the main pipe 120 define a first plane V1, and D1 and the mid-section of the main pipe 120 define a second plane V2. The second plane V2 is perpendicular to the first plane V1. The first end of the first branch pipe 130 and the first end of the second branch pipe 140 are perpendicular to and connected to the two ends of the main pipe 120, respectively. The second ends of the first branch pipe 130 and the second branch pipe 140 are located on both sides of the first plane V1, respectively. The first output section 150 is connected to the second end of the first branch pipe 130 and the liquid output direction is D2. The second output section 160 is connected to the second end of the second branch pipe 140 and the liquid output direction is D3. D2 and D3 are arranged in a direction away from the second plane V2, respectively.

[0052] The above design satisfies the following: the second ends of the first branch pipe 130 and the second branch pipe 140 are distributed on both sides of the first plane V1, so that the liquid flowing out from the two branch pipes has a height difference in space. When the sprayer 1 is started, the branch pipe located above the first plane V1, together with its corresponding output part, can spray to a farther position, while the branch pipe located below the first plane V1, together with its corresponding output part, can cover the nearby position. On the one hand, it is not necessary to raise the spray angle to increase the head, and on the other hand, it can reduce the spray dead angle at the near position formed by the shortest spray distance of the traditional sprayer. At the same time, the output directions D2 and D3 formed by the first output part 150 and the second output part 160 are located on both sides of the second plane V2 and expand outward. The sprayer only needs to swing in a small range in the horizontal direction to obtain a large spray width, which improves the spraying efficiency and the uniformity of the spray.

[0053] In some embodiments, the angle between the first branch pipe 130 and the first plane V1 is θ11, and the range of θ11 is 120°-140°, preferably 130°. The angle between the second branch pipe 140 and the first plane V1 is θ21, and the range of θ21 is 120°-140°, preferably 130°. The specific angle selection range between the branch pipe and the first plane V1 in this embodiment can obtain a reasonable head range. When the angle θ11 between the first branch pipe 130 and the first plane V1 and the angle θ21 between the second branch pipe 140 and the first plane V1 are significantly greater than 140°, the height difference between the first branch pipe 130 and the second branch pipe is small, and the effect on improving the head is not obvious. When the angle θ11 between the first branch pipe 130 and the first plane V1 and the angle θ21 between the second branch pipe 140 and the first plane V1 are less than 120° but greater than 90°, the height difference between the first branch pipe 130 and the second branch pipe 140 is large, which will cause a vacuum zone between the spray range formed by the first output section 150 and the second output section 160. When the angle θ11 between the first branch pipe 130 and the first plane V1 and the angle θ21 between the second branch pipe 140 and the first plane V1 are both less than 90°, the input direction and the output direction will become opposite. This situation is not considered.

[0054] In some embodiments, D2 has an angle θ12 with the axis of the first branch pipe 130, where θ12 is selected from a range greater than 90° and less than θ11. D3 has an angle θ22 with the axis of the second branch pipe 140, where θ22 is selected from a range greater than θ21 and less than 150°. In this embodiment, by adjusting the angle θ12 between D2 and the first branch pipe 130 and the angle θ22 between D3 and the second branch pipe 140, D2 and D3 are positioned so that they extend slightly downward relative to the first plane V1. This spray angle is more suitable for spraying herbicides onto the ground.

[0055] In some embodiments, D2 has an angle θ13 with the second plane V2, and D3 has an angle θ23 with the second plane V2. The selection range of θ13 and θ23 is limited according to the actual spray length of the sprayer and the required spray range. It should be noted that when the data of θ13 and θ23 are small, the dead angle between the spray range formed by the first output section 150 and the second output section 160 will become larger, while when the data of θ13 and θ23 are too large, the actual spray width will be reduced. Therefore, it is necessary to limit the opening angle of the first branch pipe 130 and the second branch pipe 140 relative to the second plane V2 according to the actual working conditions to obtain a reasonable spray width range.

[0056] In some embodiments, the first output section 150 includes a connector 151, a one-way throttle valve 152, and a nozzle 153. The connector 151 is cylindrical in shape and has a main flow channel inside. The axial direction of the main flow channel is D2. An inclined insertion hole is provided on the outer periphery of the connector 151 for connecting to the second end of the first branch pipe 130. The opening of the second end of the first branch pipe 130 is connected to the main flow channel. The end of the connector 151 used for liquid outflow has a built-in thread and is reliably connected to the one-way throttle valve 152 by the thread. The inlet of the one-way throttle valve 152 is aligned with and connected to the main flow channel. The nozzle 153 is installed at the outlet of the one-way throttle valve 152. All connections of the first output section 150 are reinforced with nuts. The structure of the second output section 160 is the same as that of the first output section 150, and will not be described again here.

[0057] In some embodiments, the main pipe 120, the first branch pipe 130, and the second branch pipe 140 are integrally formed. The main pipe 120, the first branch pipe 130, and the second branch pipe 140 have the same diameter. The lengths of the first branch pipe 130 and the second branch pipe 140 are shorter than that of the main pipe 120. The same pipe diameter can ensure the stability of the liquid pressure inside the spray nozzle. The integral forming of the main pipe 120 and the branch pipe can ensure the structural integrity of the spray nozzle and prevent leakage.

[0058] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
