Description

Technical Field

[0001] The utility model relates to the technical field of agricultural planting, in particular to a spraying device used for agricultural planting. Background Art

[0002] Agriculture is an industry that utilizes the growth and development laws of animals and plants to obtain products through artificial cultivation. Agriculture belongs to the primary industry. The science that studies agriculture is agronomy. The objects of agricultural labor are living animals and plants, and the products obtained are the animals and plants themselves. Agriculture is a basic industry that provides support for national economic construction and development. In the process of agricultural planting, agricultural planting fertilizer spraying devices are needed to spray fertilizers on crops.

[0003] Announcement No.: CN 213153614 U proposes a pesticide spraying device for agricultural planting. In this case, an inner sleeve rod is inserted into the inside of the outer sleeve, and perforations are opened on the left and right side walls of the outer sleeve. The overall structure is streamlined and convenient for flexible movement. At the same time, its spraying and operation are very labor-saving, thereby effectively solving the problem that small-scale pesticide spraying devices for agricultural planting are laborious to use, while large-scale spraying equipment is difficult to promote. However, in actual spraying applications, only the spraying direction of the nozzle can be adjusted, and the adjustment process is relatively cumbersome, and the spraying inclination angle of the nozzle cannot be adjusted at the same time. The spraying range is small, which is not convenient for achieving large-area uniform spraying of crops. Therefore, it is necessary to propose a pesticide spraying device for agricultural planting to solve the above problems. Utility Model Content

[0005] The above technical objectives of the utility model are achieved through the following technical solutions: a spraying device for agricultural planting, comprising a base frame and a rotating frame rotatably arranged at the upper end of the base frame, spray heads are arranged on both sides of the rotating frame, a drug delivery component for supplying medicine to the spray head is installed on the right side of the top of the base frame, an adjusting component for adjusting the inclination angle of the spray head is arranged in the rotating frame, the adjusting component comprises a screw rod rotatably arranged at the center of the inner cavity of the rotating frame, the inner cavity of the rotating frame is provided with two left-right symmetrical limit rods, the screw rod is located at the center position of the two limit rods and is parallel to them, a sliding block threadedly connected to the screw rod is slidably arranged between the two limit rods, racks are installed on the left and right sides of the sliding block, the inner cavity of the rotating frame is also provided with two left-right symmetrical rotating gears and a rotating rod coaxially connected to the rotating gear, the rotating gear is meshed with the rack, and the end of the rotating rod away from the rotating gear is fixedly connected to the spray head, and a driving component for controlling the screw rod and the rotating frame to rotate forward and reverse at the same time is arranged on the base frame.

[0006] By adopting the above technical solution, when spraying pesticides, the drug-feeding component supplies the pesticides to the spray head to spray the crops. During the spraying process, the driving component controls the forward and reverse rotation of the rotating frame to change the spraying direction of the spray heads on both sides, and controls the rotation of the lead screw at the same time. Under the restriction of the limit rods on both sides, the sliding block slides up and down, driving the racks on the left and right sides to rise and fall synchronously, and drives the two rotating gears to rotate through meshing, thereby driving the rotating rod and the spray head to rotate. When spraying pesticides, the inclination angle of the spray head can be continuously changed, so that the spraying range is greatly improved, and large-area uniform spraying of crops can be achieved quickly and conveniently.

[0007] The utility model is further configured as follows: the drug delivery component comprises a pesticide box installed on the top right side of the base frame, a water pump is provided at the upper end of the pesticide box, and the water pump is provided with water inlet pipes respectively connected to the pesticide box and the two spray heads.

[0008] By adopting the above technical solution, the water pump is driven, and the water inlet pipe draws the pesticide in the pesticide box and sends it to the spray head, so that the spray head sprays the pesticide on the crops.

[0009] The utility model is further configured as follows: the water inlet pipe is a soft PVC pipe, and both left and right side walls of the rotating frame are processed with openings for changing the angle of the spray head.

[0010] By adopting the above technical solution, the soft PVC pipe can not affect the forward and reverse rotation of the rotating frame, so that the structural design is reasonable, and the setting of the opening is convenient for the spray head to continuously change the spraying inclination angle.

[0011] The utility model is further configured as follows: the driving component includes a forward and reverse motor installed under the base frame, a rotating rod is installed at the output end of the forward and reverse motor, a main gear is installed above the outer side of the rotating rod, a gear ring meshing with the main gear is installed on the outer side of the rotating frame, and a transmission mechanism is arranged between the rotating rod and the screw rod.

[0012] By adopting the above technical solution, the forward and reverse motors control the forward and reverse rotation of the rotating rod, and the main gear drives the gear ring to rotate through engagement, so that the rotating frame rotates forward and reversely to adjust the position of the spray head, and the transmission mechanism is used to drive the screw rod to rotate simultaneously.

[0013] The utility model is further configured as follows: two left-right symmetrical pulleys are arranged at the bottom of the rotating frame, and the lower ends of the pulleys are in contact with the inner wall of the bottom frame.

[0014] By adopting the above technical solution, when the rotating frame rotates forward and backward, the pulley at the lower end is in contact with the bottom of the base frame to support the rotating frame and its overall structure, so that the rotation of the rotating frame is more stable and reliable.

[0015] The utility model is further configured as follows: the transmission mechanism comprises a synchronous wheel installed below the outer sides of the rotating rod and the screw rod, and a synchronous belt is installed between the two synchronous wheels.

[0016] By adopting the above technical solution, while the forward and reverse motors drive the rotating rod to rotate, the synchronous belt pulls the two synchronous wheels to rotate, so that the screw rod rotates at the same time. While the azimuth of the spray head is adjusted, the inclination angle is also constantly changing.

[0017] The beneficial effects of the utility model are:

[0018] 1. The utility model drives the rotating rod to rotate by the forward and reverse motors, and at the same time, the synchronous belt pulls the two synchronous wheels to rotate, so that the screw rod rotates at the same time. Under the restriction of the limit rods on both sides, the sliding block slides up and down, driving the racks on the left and right sides to rise and fall synchronously, and drives the two rotating gears to rotate through meshing, thereby driving the rotating rod and the spray head to rotate. When spraying pesticides, the inclination angle of the spray head can be continuously changed, so that the spraying range is greatly improved, and it is convenient and quick to achieve large-area uniform spraying of crops.

[0019] 2. In the utility model, under the rotation of the rotating rod, the main gear drives the gear ring to rotate through meshing, so that the rotating frame rotates forward and reversely, thereby adjusting the direction of the spray head and further improving its spraying range. The device changes the inclination angle while changing the spraying direction, and is driven by a motor, which can greatly save the use cost of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS
