Description

Technical Field

[0001] The utility model relates to the technical field of agricultural film drip performance testing mechanisms, in particular to an agricultural film drip performance testing mechanism. Background Art

[0002] Agricultural film is mainly a film used for agricultural planting. After production, it needs to be tested for drip performance, which requires the use of a testing device.

[0003] At present, when testing, the test device is generally directly covered with agricultural film on the tube, and then the top of the tube is pressed down with a heavy object to seal it. However, when sealing in this way, there is no clamping of the outer ring of the tube, which may cause air leakage, thereby reducing its test structure. Summary of the Invention

[0004] In order to solve the above problems, the purpose of the present invention is to provide a testing mechanism for the dripping performance of agricultural films to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model proposes an agricultural film drip performance testing mechanism, comprising a test box, a through pipe is fixedly installed on the top of the test box;

[0006] A clamping mechanism is provided on the top of the test box, and the clamping mechanism includes a semicircular plate, a fixed plate, a support plate, a slider and a slide groove. Two slide grooves are provided on the top of the test box, and the inner walls of the two slide grooves are slidably connected with sliders. The tops of the two sliders are fixedly installed with support plates, and the tops of the two support plates are fixedly installed with fixed plates. The sides of the two fixed plates close to each other are fixedly installed with semicircular plates that fit the through pipe.

[0007] In one example, a motor is fixedly mounted on one side of the test box, and a bidirectional lead screw is fixedly mounted on the output shaft of the motor.

[0008] In one example, the outer rings of the bidirectional screws are threadedly connected to movable plates, one side of the two movable plates is fixedly mounted with connecting plates, and one side of the two connecting plates is fixedly connected to the support plate.

[0009] In one example, a box door is hinged on the front side of the test box, and a door handle is fixedly installed on the front side of the box door.

[0010] In one example, universal wheels are fixedly mounted on the four corners of the bottom of the test box.

[0011] In one example, a placement plate is fixedly installed on the bottom of the inner wall of the test box.

[0012] The agricultural film drip performance testing mechanism proposed by the utility model can bring the following beneficial effects:

[0013] 1. This agricultural film drip performance testing mechanism clamps the agricultural film on the through tube by moving the support plates toward each other and the fixing plate driving the semicircular plates to move toward each other, thereby preventing air leakage during the drip performance test. The agricultural film on the through tube is clamped by the two semicircular plates, thereby improving its airtightness.

[0014] 2. This agricultural film drip performance testing mechanism drives the slider to move in the slide groove when the support plate moves. At this time, the slide groove limits the slider, thereby limiting the support plate, and enabling the support plate to drive the two semicircular plates to better fit the surface of the through pipe, thereby better clamping the agricultural film on it.
