Embodiment Construction

[0012] The specific implementation manners of the embodiments of the present invention will be described below with reference to the accompanying drawings. Such as figure 1 , as shown in Figure 2: a fixed support foot 1 is provided, and the fixed support foot 1 is connected to the cylindrical shell 3 through the height and angle adjustment device 2, and the height and angle adjustment device 2 can use devices such as a tripod to adjust the cylindrical shape The angle and height of the housing 3. The partition plate 4 arranged in the cylindrical housing 3 divides the inner cavity of the cylindrical housing 3 into a sphere launch chamber 5 and an air storage chamber 6, and a flange 18 is connected to the rear end of the cylindrical housing 3, and the flange 18 Air inlet 7 is arranged on. The air inlet 7 is connected to the output end of the air compressor 9 through the release valve 8 installed on the pipeline, and the other output end of the air compressor 9 is connected to t...

Abstract

The invention discloses a ball transmitting device for testing the sports field capable of ensuring the serving speed consistent with an angle and a set value to ensure the accurate test result with simple structure and easy operation. A fixation armbrace is connected with a barrel-type casing by a height and angle adjustment device. A baffle in the barrel-type casing divides the cavity of the barrel-type casing into a ball transmitting cavity and a gas storage cavity. A gas inlet is set at the back-end of the barrel-type casing and connected with the output end of a gas compressor by a releasing valve, and another output end of the gas compressor is communicated with the gas storage cavity. An inner cylinder is axially fixed in the gas storage cavity and the front-end of the inner cylinder is communicated with the ball transmitting cavity and a bidirectional pneumatic valve is set between the back-end of the inner cylinder and the gas inlet.

Description

Technical field: [0001] The invention relates to a device for testing sports grounds, in particular to a ball launching device for testing sports grounds with simple structure and easy operation, which can ensure that the speed and angle of the ball are consistent with the set values, thereby ensuring accurate test results. Background technique: [0002] The ground materials of the existing sports venues include floor, plastic, artificial turf, natural turf, etc. No matter what kind of venue, for a ball (volleyball, basketball and football, etc.) There are standard requirements for state parameters such as orientation angle, and it is necessary to regularly test the motion state of the ball after it lands. The current test method is that the ball is sent out by a person, and then the motion state data of the ball is collected and calculated by radar speedometers, computers and other testing devices to judge whether it meets the requirements. Since artificially serving the b...
