Description

Technical Field

[0001] The utility model relates to the field of spray devices, in particular to a spray device for sterile seedling planting. Background Art

[0002] With the deepening of plant nutrition research and the development of agricultural facility technology, sterile seedlings have become an important part of many research and agricultural production. Especially in the study of organic nutrition, small molecules such as amino acids will be quickly decomposed and utilized by microorganisms, so many organic nutrition studies can only be carried out under sterile conditions. During the planting process of sterile seedlings, a spray device is required to maintain the humidity inside the planting rack.

[0003] The existing spray device pushes two screw sleeves to move toward each other at the same time through a bidirectional screw. During the movement, the screw sleeve drives the sliding rod to slide inside the swing rod and drives the swing rod to rotate with the pin shaft as the axis. The swing rod drives the pipeline to rotate toward each other, which can achieve the effect of changing the spraying angle and range of the pipeline, solving the problem that the existing spray device for planting racks does not have the effect of adjusting the spraying angle.

[0004] However, the position of the existing spray device is fixed, so multiple sets of spray components need to be installed to achieve the effect of covering the spray, which increases the installation cost of the spray component. At the same time, since the position of the spray component is fixed, when the internal blockage and dirt need to be cleaned after long-term use, the staff needs to climb to the installation height to clean it, which brings inconvenience to the cleaning work. Utility Model Content

[0005] The utility model aims to provide a spray device for planting sterile seedlings, which is used to solve the problem that the existing spray device is fixed in position, and multiple groups of spray components need to be installed to achieve the effect of covering spray, which increases the installation cost of the spray components. At the same time, since the position of the spray components is fixed, when the internal blockage and dirt need to be cleaned after long-term use, the staff needs to climb to the installation height to clean it, which brings inconvenience to the cleaning work.

[0006] Therefore, the utility model provides a spray device for planting sterile seedlings, including a support rod, a lifting mechanism and a spray mechanism. A lifting mechanism with adjustable height is arranged inside the support rod, a cross beam is installed at the upper end of the lifting mechanism, a separately detachable spray mechanism is arranged on the lower side of the cross beam, and an electric bottom wheel is installed at the lower end of the support rod.

[0007] Preferably: the lifting mechanism includes a bottom groove, a first bevel gear is installed on the inner wall of the front end of the bottom groove, a knob is connected to the front end of the first bevel gear, a second bevel gear is installed on the inner wall of the upper end of the bottom groove, a telescopic groove is opened on the outside of the upper end of the bottom groove, a screw is installed in the telescopic groove, and a telescopic plate is mounted on the outer wall of the screw.

[0008] Preferably: the spray mechanism comprises a slot, a plug plate is inserted in the slot, a card slot is provided on the side wall of the slot, inner slots are symmetrically provided on the front and rear side walls at both ends of the plug plate, a hydraulic push rod is installed in the inner slot, a spring is sleeved on the outer wall of the hydraulic push rod, a card plate is sleeved on the outside of the spring, a pull plate is installed on the outer wall of the card plate in the front and rear directions, and a sprayer is installed on the lower end of the plug plate.

[0009] Preferably, the first bevel gear meshes with the first bevel gear.

[0010] Preferably: the first bevel gear is connected to the screw.

[0011] Preferably, the cross-sectional dimensions of the card slot match the cross-sectional dimensions of the card plate.

[0012] Preferably, the clamping plate is connected to one end of a spring, and the other end of the spring is connected to a side wall of the hydraulic push rod.

[0013] The utility model discloses that when it is necessary to spray the sterile seedlings, according to the planting range of the sterile seedlings, the knob is twisted to drive the first bevel gear to rotate, and the meshing drives the second bevel gear to rotate, which drives the connected screw knob, and the meshing drives the telescopic plate to move vertically up and down in the telescopic groove, and drives the crossbeam to adjust the height up and down, so as to adjust the height of the installed sprayer. The higher the height, the larger the spraying range and the lower the spraying density. On the contrary, the smaller the spraying range and the higher the spraying density are at the end of the height. After a long period of spraying operation, the sprayer needs to be maintained, and the crossbeam is controlled to move down so that the staff can directly reach the height. The pull plates are pulled from both sides toward the center respectively, driving the card plate to disengage from the card slot, so that the card plate moves in the direction of the hydraulic push rod, and potential energy is generated by the hydraulic push rod and the spring compression. When the card plate is completely out of the card slot, the plug plate is pulled downward to disengage it from the slot, and the sprayer can be disassembled separately for separate maintenance, thereby ensuring subsequent normal operation.
