[0001] The invention relates to the field of fertilizing agricultural machinery, and in particular to a grape planting fertilizing device. Background Art

[0002] When planting grapes, it is necessary to spray fertilizer on grapes regularly, but the existing fertilization equipment has the following shortcomings. First, there is uneven spraying when spraying fertilizer. The existing grape fertilizer spraying device can only spray the grapes from the outside, and cannot spray the inside of the grapes. This will affect the uniform coverage of liquid fertilizer and reduce the growth effect. In particular, when spraying foliar fertilizer, it can only be sprayed on the leaves outside the crown, and the spraying effect is even worse. Second, spraying grapes from the outside will cause serious waste of fertilizer. Third, the existing fertilizer spraying device has a small number of nozzles and low spraying efficiency. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the present invention provides a grape planting fertilization device which can spray grapes deeply into the interior of the grapes, sprays evenly, does not waste fertilizer, and has high spraying efficiency.

[0004] The purpose of the present invention is to be achieved through the following technical solutions: A grape planting and fertilizing device comprises a vehicle body, a motion device, and a support rod assembly, wherein the motion device is slidably connected to the vehicle body, a group of support rod assemblies are slidably connected to the motion device, the support rod assembly comprises a support rod, two sliding sleeves are slidably connected to the support rod, each sliding sleeve is connected to a hinge sleeve, a nozzle screw is connected in the middle of each hinge sleeve, a group of nozzle screws are connected to a push plate at the rear side, the push plate is slidably connected to a frame, a group of support rod assemblies are connected by connecting rods, one of the support rod assemblies is connected to a transverse slider, the transverse slider is connected to a longitudinal slide seat, the longitudinal slide seat is connected to a drive seat and the push plate, and the drive seat is connected to the frame.

[0005] The upper part of the frame is provided with a group of frame guide sleeves, which are slidably connected to a group of frame guide rods at the lower part of the frame. The rear side of the frame is rotatably connected to a No. 1 lead screw, and the No. 1 lead screw is threadedly connected to the frame screw hole at the rear side of the frame.

[0006] A support rod sleeve is provided in the middle of the support rod, a support rod screw hole is provided in the middle of the support rod sleeve, two symmetrical support rod waist grooves are provided on the upper and lower sides of the support rod sleeve, a sliding sleeve hole is provided in the middle of the sliding sleeve, the sliding sleeve is slidably connected to the support rod, the articulated sleeve passes through the support rod waist groove and the sliding sleeve hole, and the articulated sleeve is fixedly connected to the sliding sleeve hole.

[0007] The rear side of the frame is provided with a push plate, and two frame slide grooves on the rear side of the frame are slidably connected to the two push plate sliders at the bottom of the push plate. A No. 3 lead screw is provided between the push plate and the frame, and the No. 3 lead screw is rotatably connected to the front bracket lead screw seat at the bottom of the frame. The No. 3 lead screw is threadedly connected to the drive seat screw hole at the bottom of the push plate, and the front side of the No. 3 lead screw is connected to the motor fixed at the bottom of the frame.

[0008] A rectangular front bracket is provided on the front side of the frame, and a front frame slide groove is provided on the inner sides of the upper and lower sides of the front bracket. A support rod assembly is fixedly connected in the middle of the front frame slide groove, and a group of support rod assemblies are respectively provided on both sides of the fixed support rod assembly. A group of connecting rods are hinged between the support rod assemblies, and a group of connecting rods are hinged into a diamond structure. The middle of a group of connecting rods is hinged to a support rod sleeve, and both sides of a group of connecting rods are hinged on the hinge sleeve.

[0009] A nozzle screw rear seat is provided on one side of the nozzle screw, and a nozzle fixing seat is provided on the other side of the nozzle screw. A nozzle screw is threadedly connected in the support rod screw hole in the middle of each support rod and the hinge sleeve screw hole of each hinge sleeve respectively. The nozzle is fixed in the nozzle fixing seat on the front side of each nozzle screw. A spring is provided on the rear side of each nozzle screw. The spring is sleeved on the outside of the nozzle screw, one side of the spring presses against the corresponding hinge sleeve and the rear side of the support rod screw hole, the rear side of the spring presses against the corresponding nozzle screw rear seat, and the rear side of the nozzle screw presses against the rear side of the nozzle screw rear seat.

[0010] Beneficial effect: When the No. 1 lead screw of the present invention rotates, it drives the frame to move up and down, so that the nozzle of the device is aimed at the crown of the grapes. The frame that moves up and down can meet the needs of spraying grapes at different heights. If the crown height is relatively large, the height of the moving device can also be adjusted in batches so that the nozzle sprays in layers, ensuring that the nozzle of the device can pass through the crown. A group of nozzle screws and a support rod assembly are threadedly connected, and a group of nozzles are gradually inserted into the crown from the outside of the crown, and the nozzles are in a rotating state. The entire crown is sprayed evenly, the spraying effect is good, and the spraying efficiency is high. When the motor rotates in the opposite direction, the push plate moves backward, and the nozzle screw resets to the rear side under the action of the spring. The nozzle screw moves backward while rotating in the opposite direction, and the nozzle slowly withdraws from the crown. When the nozzle withdraws, Spraying can be continued or stopped, which can achieve the best spraying effect and save fertilizer. When the push plate drives the nozzle screw to move forward and backward, it drives the longitudinal slide seat to move forward, and the longitudinal slide seat drives the transverse slide block to move forward. When the transverse slide block moves forward, it moves along the wave groove in a wavy trajectory. When the transverse slide block moves in a wavy manner, it drives the outermost support rod assembly to move left and right. The left and right movement of the outermost support rod assembly drives all the active support rod assemblies to slide synchronously through the connecting rod. The adjacent support rod assemblies change synchronously and equidistantly, so that all nozzles swing left and right, and further make the nozzle spray evenly. Rotating the No. 2 screw can drive the drive seat to move left and right, thereby controlling the extension and retraction width of the support rod assembly and the coverage range of the nozzle, which ensures that the nozzle covers the branch crown and saves fertilizer.

[0034] An operating method of a grape planting and fertilizing device comprises the following steps: a first step, when using the device, the device is pulled near the grapes, and a first lead screw 120 is rotated. When the first lead screw 120 rotates, the frame 210 is driven to move up and down, so that the nozzle of the device is aimed at the crown of the grapes; a second step, a motor 310 is started. When the motor 310 rotates, the third lead screw 290 is driven to rotate. When the third lead screw 290 rotates and drives the push plate 250 to move forward, the push plate 250 drives a group of nozzle screws 260 to move forward, and the nozzle screws 260 are driven to move forward. When moving forward, the nozzle screw 260 rotates under the drive of the hinge sleeve 430 and the support rod screw hole 412. The nozzle screw 260 rotates while moving forward, and the nozzle screw 260 drives the corresponding nozzle to move forward and rotate. A group of nozzles are gradually inserted into the inside of the crown from the outside of the crown, and the nozzles are in a rotating state. The entire crown is sprayed evenly. When the nozzle passes through the crown, the motor 310 rotates in the opposite direction, the push plate 250 moves backward, and the nozzle screw 260 is reset to the rear side under the action of the spring 320. The nozzle slowly withdraws from the crown while moving backward and rotating in the opposite direction. When the nozzle withdraws, the spraying can be continued or stopped. When the push plate 250 drives the nozzle screw 260 to move forward and backward, the longitudinal slide seat 230 is driven to move forward. The longitudinal slide seat 230 drives the horizontal slide block 240 to move forward. When the horizontal slide block 240 moves forward, it moves along the wave groove 221 in a wave-shaped trajectory. When the horizontal slide block 240 moves in a wave-shaped manner, it drives the outermost support rod assembly 400 to move left and right. The outermost support rod assembly 400 moves left and right through the connecting rod 2 70 drives all the movable support rod assemblies 400 to slide synchronously, and the adjacent support rod assemblies 400 move synchronously and equidistantly, so that all the nozzles swing left and right, and further make the nozzles spray evenly. Rotating the second screw 280 can drive the drive seat 220 to move left and right, thereby controlling the extension and retraction width of the support rod assembly 400 and the coverage range of the nozzles, which can not only ensure that the nozzles cover the branch crowns but also save fertilizers. The fertilizers are easy to absorb and evenly distributed, which prevents grapes from being injured. It is safe to use and prevents fertilizers from volatilizing and losing, thereby improving the utilization rate of fertilizers.

[0035] When the No. 1 lead screw 120 rotates, it drives the frame 210 to move up and down, so that the nozzle of the device is aimed at the grape crown. The frame 210 that moves up and down can meet the needs of spraying grapes at different heights. If the height of the crown is relatively large, the height of the motion device 200 can also be adjusted in batches so that the nozzle sprays in layers, ensuring that the nozzle of the device can pass through the crown. A group of nozzle screws 260 and the support rod assembly 400 are threadedly connected, and a group of nozzles are gradually inserted into the crown from the outside, and the nozzles are in a rotating state. The entire crown is sprayed evenly, the spraying effect is good, and the spraying efficiency is high. When the motor 310 rotates in the opposite direction, the push plate 250 moves backward, and the nozzle screw 260 resets to the rear side under the action of the spring 320. The nozzle screw 260 moves backward while rotating in the opposite direction, and the nozzle slowly withdraws from the crown. When the nozzle withdraws, you can continue spraying or stop spraying. When the push plate 250 drives the nozzle screw 260 to move forward and backward, it drives the longitudinal slide seat 230 to move forward, and the longitudinal slide seat 230 drives the horizontal slide block 240 to move forward. When the horizontal slide block 240 moves forward, it moves along the wave groove 221 in a wave-like trajectory. When the horizontal slide block 240 moves in a wave-like manner, it drives the outermost support rod assembly 400 to move left and right. The outermost support rod assembly 400 moves left and right through the connecting rod 270 to drive all the active support rod assemblies 400 to slide synchronously. The adjacent support rod assemblies 400 move synchronously and equidistantly, so that all the nozzles swing left and right, and further make the nozzles spray evenly. Rotating the No. 2 lead screw 280 can drive the drive seat 220 to move left and right, thereby controlling the extension and retraction width of the support rod assembly 400 and the coverage range of the nozzles, which ensures that the nozzles cover the branch crowns and save fertilizers.
