[0002] The housing parts of high-speed rice transplanters play a pivotal role when the high-speed rice transplanters are running at high speed. Once the housing leaks, the rice transplanters will be in danger of "biting". Therefore, the airtightness test technology of the housing parts of high-speed rice transplanters has become an important part of product recommendations to detect the leakage of the housing castings and ensure the reliability of the product. At present, the Chinese patent application number CN201320361136.6 discloses an airtightness test device for housing parts of high-speed rice transplanters, including several sealing fixtures and sealing positioning mechanisms. The sealing fixtures and sealing positioning mechanisms constitute a combined fixture, which clamps the housing of the high-speed rice transplanters and seals the orifice of the housing of the high-speed rice transplanters, and is placed in the leakage detection liquid box. One of the sealing fixtures is provided with an air inlet, and the other sealing positioning mechanism is provided with an exhaust port; the air inlet is connected to the air inlet stop valve, and the exhaust port is connected to the exhaust stop valve. Two vertical parallel guide rails are provided in the leakage detection liquid box, and the combined fixture is provided with a lifting guide wheel, and the piston push mechanism set up on the top is fixedly connected to the combined fixture. A stand is arranged above the leakage detection liquid box, and an electrical control unit and a pneumatic control unit are arranged on the stand respectively.

[0003] However, during the process of positioning and fixing the high-speed rice transplanter case parts, the existing high-speed rice transplanter case parts airtightness testing device still requires staff to manually lift the high-speed rice transplanter case parts to the installation height, and then adjust the combined clamp to clamp and fix them. Since the high-speed rice transplanter case parts are heavy, it will be very difficult for one person to lift them, and another person is needed to assist in operating the combined clamp for clamping. The overall practicality needs to be discussed. Utility Model Content

[0024] See also Figure 1-3 A device for testing air tightness of box parts of a high-altitude rice transplanter comprises a testing device body 1 for testing a box part body 2, and also comprises a combined clamp 3 for fixing the box part body 2 at the bottom of the testing device body 1, a fixing frame 4 is detachably fixedly installed on the outside of the testing device body 1, a slide groove 5 communicating with an inner cavity is arranged on one side of the fixing frame 4, a slider 6 is slidingly penetrated on the outside of the slide groove 5, a rotating shaft 7 for driving the slider 6 to slide and lift along the slide groove 5 is arranged in the inner cavity of the fixing frame 4 for longitudinal rotation, and a placement frame 9 for placing the box part body 2 is fixedly connected to the outside of the slider 6, and clamps 10 for clamping the box part body 2 are symmetrically arranged on both sides of the placement frame 9.

[0025] The outside of the fixing frame 4 is fixedly connected with a bending block 401 that is clamped on the outside of the test device body 1, and the bending block 401 is detachably fixedly connected to the test device body 1 through a fastener. Through this detachable installation method, the fixing frame 4 and the placement frame 9 of the lifting box part body 2 can be fixedly installed on the outside of the existing test device body 1 for use.

[0026] The surface of the rotating shaft 7 located in the inner cavity of the fixing frame 4 is provided with threads, and the rotating shaft 7 threads penetrate and connect to the slider 6 . The upper end of the rotating shaft 7 movably penetrates the fixing frame 4 and is fixedly connected to a handle 701 .

[0027] Among them, a fixing seat 801 is fixedly connected to the bottom of the fixing frame 4, and a threaded rod 802 is movably inserted at the lower end of the fixing seat 801, an adjusting sleeve 803 is rotatably connected to the bottom of the fixing seat 801, and the adjusting sleeve 803 is threadedly sleeved on the outer side of the threaded rod 802, and a supporting seat 8 is fixedly connected to the bottom of the threaded rod 802, and a limiting block 804 is fixedly connected to the inner wall of the fixing seat 801 near the bottom, and limiting grooves 805 that are snap-fitted with the limiting blocks 804 are longitudinally arranged on both sides of the threaded rod 802. Based on the above structure, when the device is in use, since the box body part main body 2 to be lifted is heavy, in order to ensure the operating stability of the fixed frame 4, the staff can rotate the adjusting sleeve 803 and threadably drive the threaded rod 802. Since the limiting groove 805 on the outside of the threaded rod 802 is clamped and limited with the limiting block 804 on the inner wall of the fixed seat 801, at this time, the adjusting sleeve 803 drives the threaded rod 802 to descend, and drives the support seat 8 at the bottom to support the ground for reinforcement as a whole, thereby ensuring the relative stability of the fixed frame 4 during lifting.

[0028] Among them, embedding grooves 901 are evenly arranged at the bottom of the inner cavity of the placement frame 9, and balls 902 are movably embedded inside the embedding grooves 901. After the box part body 2 is lifted to a height that is docked with the combination clamp 3, the box part body 2 can be pushed forward and backward to push it to the position of the combination clamp 3, which is convenient for fixing it. The balls 902 can reduce the friction of the pushing and moving of the box part body 2, making it convenient for it to slide smoothly.

[0029] Among them, both sides of the splint 10 are connected to the side walls of the placement frame 9 through spring telescopic rods 1001, and the spring telescopic rods 1001 are in an extended state by default. The extended spring telescopic rods 1001 are used in conjunction with the splint 10 to assist in fixing the box part body 2 placed on the upper end of the placement frame 9.

[0030] Based on the above structure, the device installs a fixed frame 4 and an associated connecting structure on the outside of the existing test device body 1, places the box part body 2 on the upper end of the placement frame 9 at the bottom, and is relatively fixed with the clamps 10 on both sides. Then, the rotating shaft 7 is rotated by the handle 701 and the slider 6 is threadedly driven to slide longitudinally along the slide groove 5 on the outside of the fixed frame 4, and the placement frame 9 connected to the slider 6 is driven to increase in height. When the box part body 2 at the upper end of the placement frame 9 is lifted to the height docking with the combination fixture 3, the box part body 2 at the upper end of the placement frame 9 is pushed inward with force to push it onto the combination fixture 3 and fix it. The box part body 2 can be tested in conjunction with the existing test device body 1.

[0031] It should be noted that, firstly, the test device body 1 in this device is the airtight test device for the housing parts of a high-speed rice transplanter in the existing comparative documents, and no redundant description is made in this case. Secondly, if conditions permit, the handle 701 can be replaced with a micro motor drive, which is labor-saving and convenient.
