Abstract
Description
Technical Field
[0001] This utility model relates to the field of grassland ecological improvement, and more specifically, to a biological agent spraying device suitable for grassland ecological improvement. Background Technology
[0002] The restoration of damaged soil in open-pit mines typically employs ecological restoration methods such as vegetation bags, eco-bags, vegetation mats, natural restoration, and topsoil improvement. However, in mining areas where soil structure is damaged, the surface is exposed, and soil erosion occurs, leading to insufficient pH levels and nutrients for the growth of grasses such as eco-bags or turf. Therefore, it is necessary to first apply biological agents to adjust the pH or provide nutrients to the initial or secondary planting to aid grass growth. If traditional water pipe irrigation is used, the soil's ability to retain nutrients is weak before initial restoration, rendering even large amounts of biological agents ineffective. Therefore, it is necessary to apply agents in small, frequent applications covering the entire area to ensure the grasses' cyclical growth needs are met. Utility Model Content

[0024] First Embodiment
[0025] Please see Figure 1 This embodiment provides a biological agent spraying device suitable for grassland ecological improvement. The biological agent spraying device includes a frame 001 and a folding spray bar 110 disposed on the back of the frame 001. The frame 001 is used to assemble the medicine tank and other control components, while the folding spray bar 110 serves as a support bracket for the biological agent spraying device to expand the spraying surface.
[0026] Specifically, the frame 001 has a fixed area for placing the medicine tank. This fixed area consists of a back plate, a base plate, and a frame. The first side of the back plate is the mounting surface for the folding spray boom 110, and the second side serves as the fixing surface for the medicine tank, control components, power supply, and other devices. Unlike a typical frame 001, the back plate has rotating seats 111 at both ends of its lower part for mounting the folding spray boom 110. This allows the folding spray boom 110 to be rotated and folded or unfolded based on the rotating seats 111. To ensure folding consistency and connection stability, the back plate has an arc-shaped groove 112 centered on the rotating seats 111. The base plate is used to fix the biological agent spraying device to a vehicle, such as the trunk of a pickup truck.
[0027] The folding spray boom 110 is rotatably connected to the rotating base 111. The folding spray boom 110 includes a rectangular spray boom support 113, a trapezoidal spray boom support 114, and a triangular spray boom support 115 connected in sequence and decreasing in length. The folding spray boom 110 is designed with a gradually decreasing width, making the support at the far end lighter and the support at the near end heavier, thereby ensuring the stability of the pesticide spraying device during the driving and spraying process. For ease of understanding, Figure 1 The folding spray boom 110 has one side in an unfolded state and the other side in a folded state. The trapezoidal spray boom bracket 114 is a right trapezoid, and the lower base of the trapezoidal spray boom bracket 114 and the rectangular spray boom bracket 113 are connected by a first rotating assembly; the triangular spray boom bracket 115 and the upper base of the trapezoidal spray boom bracket 114 are connected by a second rotating assembly.
[0028] The rectangular spray boom bracket 113 includes a rectangular bracket body and a support bar disposed inside the rectangular bracket body. A hinge seat is provided at one bottom corner of the rectangular bracket body. The hinge seat is mounted on a rotating base 111 and can rotate based on the rotating base 111. It can be equipped with two rotating motors, or it can be equipped with a single rotating motor combined with a coaxial dual-output transmission structure, a dual-input dual-output synchronous reverse transmission structure, a worm gear dual-output transmission structure, or other transmission mechanisms to achieve one rotation input and two opposite rotation outputs, thereby realizing the electric storage function of the folding spray boom 110.
[0029] A guide seat 116 is provided at one top corner of the rectangular support body. The guide seat 116 is fitted onto the arc-shaped slide groove 112, thus ensuring the movement path of the rectangular support body when stored. At the same time, the guide seat 116 is inserted into the arc-shaped slide groove 112 to provide traction and support force when the rectangular support body extends. The other two corners of the rectangular support body are provided with first pivot mounting seats 118 for mounting trapezoidal spray boom brackets 114. The spray nozzles are set on the rectangular support body, preferably evenly distributed at the bottom of the rectangular support body. Multiple support bars 117 arranged in a continuous V-shape are provided in the middle of the rectangular support body, which not only improves the support effect but also reinforces the hose. In the extended state, they can also be fixed to the pickup truck trunk with straps.
[0030] The trapezoidal spray boom bracket 114 includes a trapezoidal bracket body. Two corners on one side of the trapezoidal bracket body are provided with a second rotating shaft mounting seat 118 that cooperates with the first rotating shaft mounting seat 118. By assembling the damping rotating shaft to the first rotating shaft mounting seat 118 and the second rotating shaft mounting seat 118, the trapezoidal bracket body can be folded onto the rectangular bracket body at any angle. Two corners on the other side of the trapezoidal bracket body are provided with a third rotating shaft mounting seat 118. A spray nozzle 119 is provided on the trapezoidal bracket body.
[0031] The right-angled side of the triangular spray bar bracket 115 is provided with a fourth rotating shaft assembly 118 that matches the third rotating shaft assembly 118. The damping rotating shaft is assembled to the third rotating shaft assembly 118 and the fourth rotating shaft assembly 118, so that the triangular spray bar bracket 115 can be folded at any angle on the trapezoidal bracket body. The triangular spray bar bracket 115 is provided with a spray nozzle 119.
[0032] For further details, please see Figure 2To prevent clogging of the pesticide, improvements have been made to the pesticide tank and spray assembly in this embodiment. The pesticide tank includes a tank body 121, which is equipped with a basket-shaped filter. A high-pressure nozzle 122 is installed on the side wall of the tank body 121, and a liquid outlet is located at the bottom of the tank body 121.

The return end of the filter 123 is connected to the high-pressure nozzle 122. The main return valve 126 and the adjusting return valve 128 are located at the bottom of the tank. The inlet and outlet of valve 127, the return ends of the main return valve 126 and the adjusting return valve 128 are connected to the top opening of the medicine tank, the outlet of filter 123 is connected to the main return valve 126, the outlet of adjusting return valve 128 is connected to three medicine distributors 129, the three medicine distributors 129 are respectively connected to the spray nozzles 119 on the rectangular spray bar bracket 113, the trapezoidal spray bar bracket 114 and the triangular spray bar bracket 115, and the pressure gauge is set on the medicine distributor 129.
[0033] The biological agent spraying device is used as follows: Open the rear tailgate of the pickup truck and fix the frame 001 to the bottom of the pickup truck bed. It can be fixed by welding or bolting to the bottom of the pickup truck bed, so that the folding spray boom 110 is exposed outside the pickup truck; control the rotating seat 111 to rotate, so that the folding spray boom 110 changes from a vertically retracted state to a horizontally unfolded state; manually pull the triangular spray boom bracket 115, and the two rotating shaft mounting seats 118 rotate with the traction force, so that the rectangular spray boom bracket 113, the trapezoidal spray boom bracket 114 and the triangular spray boom bracket 115 unfold; use straps to further tie the support bar 117 to the two side panels of the pickup truck to strengthen the fixation.
[0034] After securing the equipment, pour water and pesticide into the tank, mix thoroughly, and then begin spraying. The pickup truck's spare space can hold a large amount of water, eliminating the need for multiple water refills. For enhanced automation, a stirring device and automatic water and pesticide dispensing mechanisms can be installed on the tank lid.
