Description

Technical Field

[0001] The utility model relates to the field of pest control equipment, in particular to a forestry pest control spraying device. Background Art

[0002] Forest pests refer to insects that harm forests and forest products. There are about 2,400 known species of forest pests in China, of which about 450 have traceable life histories, habits and control methods. The 20 or so most important species include the pine caterpillar (see pine caterpillar), the reddish tip borer (see pine tip pests), the Japanese pine stem scale (see pine stem scale), the Armand pine borer, the yellow-spine bamboo grasshopper, the thick-tipped two-striped pine longhorn beetle and the glabripennis longhorn beetle (see coniferous tree longhorn beetle), the poplar fan moth, the elm blue leaf beetle (see elm leaf beetle), the oil tea looper, etc. Their invasion or parasitism can cause a series of abnormal changes in the morphology, tissue or physiological ecology of trees, leading to poor growth and development, reduced yield and quality, and even the death of trees or entire forest stands and the deterioration of the ecological environment.

[0003] Forest pests are generally controlled by spraying pesticides. When spraying, the spray pot generally uses a pump as a power source. However, since forestry generally covers a large area, it is difficult to maintain energy for a long time. Therefore, charging is required to ensure the normal operation of the pump body, which reduces the spraying efficiency. At the same time, the use of pumps for spraying increases the cost of spraying. Therefore, a device is urgently needed to solve the above problems. Utility Model Content

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a forestry pest control spraying device, comprising a vehicle body, a spray pipe fixedly provided on one side of the vehicle body, a storage box fixedly provided on the top of the vehicle body, the storage box is convenient for storing liquid medicine, a first sprocket is coaxially mounted on one side of the moving wheel of the vehicle body, a second sprocket is movably mounted on one side of the vehicle body, a transmission chain is arranged around the first sprocket and the second sprocket, a limiting shaft is provided on one side of the second sprocket through a thread, a movable ring is movably sleeved on the outside of the limiting shaft, a connecting rod is fixedly provided on the top of the movable ring, and a power mechanism for conveniently pumping out the liquid medicine is embedded in the storage box.

[0006] Preferably, the power mechanism includes a hollow cylinder, a piston block, a one-way valve, a first pipe and a second pipe. The hollow cylinder is embedded and fixed on one side of the top of the storage box. The piston block is slidably arranged inside the hollow cylinder. The one-way valve is embedded and fixed at the bottom end of the hollow cylinder. The first pipe is fixed at the bottom end of the one-way valve on one side. The bottom end of the first pipe extends to the bottom end of the storage box. The second pipe is fixed at the lower end of the one-way valve on the other side. When in use, it pushes the vehicle body to move. When the moving wheel rotates, it drives the first sprocket to rotate, and drives the second sprocket to rotate through the transmission chain. When the second sprocket rotates, it pulls the connecting rod. When the connection point between the second sprocket and the connecting rod rotates to the uppermost position, the connecting rod drives the piston block to move to the upper end along the hollow cylinder, so that negative pressure is formed inside the hollow cylinder, and the medicine liquid is sucked into the hollow cylinder through the first pipe. Then, when the connection point between the second sprocket and the connecting rod rotates to the lowermost position, the connecting rod drives the piston block to move downward along the hollow cylinder, squeezing the medicine liquid inside the hollow cylinder into the second pipe, and then spraying is carried out through the spray pipe. The spraying is repeated in this way without the need for an additional power source, and the spraying work can be carried out for a long time.

[0007] Preferably, the top end of the connecting rod is movably mounted at the top end of the piston block.

[0008] Preferably, two one-way valves are provided and symmetrically fixed at both sides of the bottom end of the hollow cylinder.

[0009] Preferably, the second pipe is a rubber hose.

[0010] Preferably, one side of the second pipe is fixedly extended to the outside of the storage box and then fixed to one side of the spray pipe.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] When the utility model is in use, it pushes the vehicle body to move. When the moving wheel rotates, it drives the first sprocket to rotate, and drives the second sprocket to rotate through the transmission chain. When the second sprocket rotates, it pulls the connecting rod. When the connection point between the second sprocket and the connecting rod rotates to the uppermost position, the connecting rod drives the piston block to move along the hollow cylinder to the upper end, so that negative pressure is formed inside the hollow cylinder, and the medicine liquid is sucked into the hollow cylinder through the first pipe. Then, when the connection point between the second sprocket and the connecting rod rotates to the lowermost position, the connecting rod drives the piston block to move downward along the hollow cylinder, squeezing the medicine liquid inside the hollow cylinder into the second pipe, and then spraying is carried out through the spray pipe. The spraying is repeated in this way without the need for an additional power source, and the spraying work can be carried out for a long time. BRIEF DESCRIPTION OF THE DRAWINGS
