Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery and equipment, and in particular to a portable spraying device and method for planting agricultural products. Background Art

[0002] At present, when spraying pesticides or other spraying liquids on crops, the best effect can only be achieved by evenly spraying the diluted liquid on the stems and leaves of the plants. In some mountainous areas or special terrains, due to the relatively small area, large motor vehicle-mounted spraying equipment is inconvenient to operate, so motorized, electric or manual backpack sprayers are often used as spraying tools.

[0003] However, although the backpack sprayer is portable, it has a small capacity and needs to be prepared with liquid before use. It must then be carried manually to the designated area for spraying. For large-scale farmland spraying operations, it requires constant back and forth loading of medicine, which reduces work efficiency and increases labor intensity. If you want to save round-trip time, you need to increase the capacity of the liquid medicine. Then, the overly heavy water tank is another difficult test for the personnel.

[0004] In order to avoid the influence of the weight of the water tank on the spraying operation, relevant personnel designed a small spraying vehicle. However, since the vehicle still occupies a larger space than a person, the vehicle will inevitably run over the crops during the operation, causing damage. Therefore, it is thought of to directly install the steering wheel on the bottom of the water tank, which not only reduces the load of the personnel, but also reduces the damage to the crops, such as the pesticide spraying device disclosed in patent CN114223640A. However, this design structure still has disadvantages: the mass of the liquid storage tank becomes larger after it is filled with pesticides. It is not only time-consuming and laborious to pull it only by the connecting pipe, but also the connecting pipe will be deformed or broken over time, affecting the water outlet function of the connecting pipe. The labor intensity of the operator is high and the spraying operation efficiency is low. Summary of the invention

[0005] The purpose of the present invention is to solve the problems of high labor intensity, low efficiency of single-person operation and unsatisfactory spraying effect in existing agricultural product spraying under complex terrain, and to provide a portable spraying device for agricultural product planting, which can greatly reduce the labor intensity of the staff, improve the spraying efficiency and effect, and reduce the weight and structural cost of the whole vehicle.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A portable spraying device for planting agricultural products comprises a water tank transport vehicle, which comprises, from top to bottom, a wearable belt, a quick-connect buckle, a flexible connector, an angle adjustment mechanism, a vehicle body connecting plate, a chassis and wheels, a water tank is connected to the chassis, a lifting mechanism and a supporting device that cooperate with each other are provided on the vehicle body connecting plate, a telescopic spray rod is connected to the supporting device, one end of the telescopic spray rod is connected to a medicine pump in the water tank through a hose, so as to pump medicine liquid to the end of the spray rod for spraying; The lifting mechanism includes a rectangular guide frame, a track frame is nested in the guide frame, and the two form a sliding guide match. The inner frame of the track frame is a waist-shaped structure, and a circle of serrated track grooves is provided therein. The upper and lower parts of the guide frame are respectively connected with guide columns, and the guide columns respectively pass through the limit blocks on the corresponding sides, and the limit blocks are fixed on the vehicle body connecting plate. The guide columns and the limit blocks form a sliding guide match. A lifting gear is also provided in the guide frame. The lifting gear passes through the vehicle body connecting plate through the central axis and is connected to the driving device. The lifting gear and the track groove are meshed with each other to realize the lifting and lowering of the guide frame. The supporting device includes a universal seat fixed to the side of the guide frame. The universal seat is a 360° rotating seat and is connected to a supporting ear. The supporting ear is connected to the middle and rear sections of the telescopic spray rod and the telescopic spray rod rotates along the axis of the supporting ear. The rear end of the telescopic spray rod is connected to an elastic connecting piece, which is in turn connected to a counterweight. The counterweight is connected to the outer surface of the guide frame.

[0007] Furthermore, the wearable belt is connected to the flexible connector via a quick-connect buckle, and the flexible connector is further connected to an angle adjustment mechanism. The angle adjustment mechanism includes a pair of connecting ears and a rotating box arranged between the connecting ears. The flexible connector is fixed to the connecting ears, and a rotating locking handle is provided on the outer side of the connecting ears. The locking end of the rotating locking handle passes through the connecting ears and extends into the rotating box, and is connected to the locking disk in the rotating box, so as to realize the angle adjustment of the vehicle body and adapt to the wear of people of different heights.

[0008] Furthermore, the vehicle body connecting plate is a trapezoidal plate, the upper end of which is fixedly connected to the lower part of the rotating box and the lower end is connected to the chassis. The chassis is provided with a tank trough for carrying a water tank. The two sides of the chassis are respectively hinged to the swing arms, the outer side of the lower end of the swing arm is connected to the wheel, and the inner side of the lower end of the swing arm is connected to the outer wall of the tank trough through a shock-absorbing spring, so as to reduce the influence of the terrain on the shaking of the medicine liquid and avoid large swinging of the medicine liquid.

[0009] Furthermore, a necking structure is provided at the bottom of the water tank, which is just embedded in the tank groove. A locking belt is also provided outside the water tank, which connects the water tank to the vehicle body connecting plate to further stabilize the connection between the water tank and the vehicle body.

[0010] Furthermore, the axis of the lifting mechanism is parallel to the axis of the vehicle body connecting plate, the axis of the guide column and the axis of the guide frame coincide with each other, the center axis of the lifting gear is also arranged on the axis of the guide frame, and the length of the guide column is not less than the length of the track frame, so as to achieve complete engagement of the lifting gear and the track groove.

[0011] Furthermore, the inner frame of the guide frame is a rectangular frame with slide grooves on its upper and lower sides, and the outer frame of the track frame is also a rectangular frame with slide blocks on its upper and lower sides. The slide blocks are embedded in the slide grooves on the corresponding sides and the two form a sliding guide fit.

[0012] In order to further achieve the purpose of the present invention, a method for spraying pesticides for planting agricultural products is also provided, and the specific steps are as follows, including: (1) Put the prepared liquid medicine into the water tank, insert the water tank into the chassis and fasten the water tank to the connecting plate of the vehicle body with a locking belt; (2) The hose is connected to the medicine pump and then to the input end of the telescopic spray rod, and the telescopic spray rod is connected to the guide frame through the support device; (3) Use the angle adjustment mechanism to adjust the spray device to a suitable angle and tie the wearable belt around the waist; (4) Start the driving device of the lifting mechanism to drive the lifting gear to rotate, drive the track frame and the guide frame to move up and down, thereby driving the supporting device on the guide frame to move up and down. When the determined height is reached, the lifting gear stops rotating; (5) The telescopic spray rod can be rotated 360 degrees up and down and left and right under the drive of the universal seat, and a labor-saving rod structure is formed under the action of the support ears, elastic connectors and counterweights. The medicine pump draws spray liquid from the water tank and sprays it out from the nozzle end of the telescopic spray rod to spray crops within the rotation diameter range. If the diameter range needs to be expanded, the telescopic spray rod can be appropriately lengthened; (6) After the spraying operation is completed, close the quick-connect locks to quickly separate the personnel from the vehicle body, then take out and put away the water tank on the vehicle body, and finally fold the vehicle body for storage.

[0013] Compared with the prior art, the specific advantages of the technical solution of the present invention are: (1) The present invention is suitable for spraying low-growing crops for pest control and disease prevention. The wearable belt can be connected to the operator by simply tying it around the operator's waist. There is no need to carry a water tank, which reduces the operator's labor intensity. At the same time, it does not occupy a large space and reduces damage to crops. (2) The present invention adopts a frame-type lifting mechanism, which only requires one motor to drive the spray boom to rise and fall. The frame is light in weight and low in cost. Compared with a single gear rack drive, the structure is more stable and reliable. (3) The support device of the present invention is more convenient for operators to perform spraying operations, which saves more effort when holding the spray rod. It can also be raised and lowered together with the frame structure and can rotate freely 360°, thereby improving the spraying efficiency and spraying effect. BRIEF DESCRIPTION OF THE DRAWINGS
