[0028] To enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] The present utility model provides a connecting member for a beam and a column of a vegetable planting greenhouse as shown in Figures 1-6 Figure 5. It includes a cross beam 1, a column 2, and a beam-through 7. Jitter components 3 capable of cleaning the snow accumulated on the top of the greenhouse are installed at both ends of the cross beam 1. The column 2 is connected to the bottom of the jitter component 3. A roof support column 4 is jointly installed at the top of the two jitter components 3. Multiple roof support columns 4 are connected by a beam-through 7. Two driving components 6 are provided on the cross beam 1. A trigger component 9 is provided at the top of the driving component 6. A support frame 8 is provided at the top of the trigger component 9. The support frame 8 is connected to the adjacent roof support column 4. The driving component 6 is in transmission connection with the two adjacent jitter components 3.

[0030] When the weight of the accumulated snow reaches a level that can drive the driving component 6 to operate, and through the transmission connection, it drives the adjacent jitter component 3 to operate. The jitter component 3 jitters to push the top of the greenhouse to jitter, thereby realizing the cleaning of the snow on the top. Starting the device by the weight of the accumulated snow can avoid excessive accumulation of snow on the roof, preventing the risk of collapse due to excessive support pressure on the device.

[0031] As shown in Figures 3-6 Figure 6, the jitter component 3 includes a frame body 31, a mounting block 32, a sleeve 33, a push rod 34, a support block 35, a connecting block 36, a mounting plate 37, a pressing rod 38, a cam 39, and a single-slot pulley 310. The frame body 31 is connected to the cross beam 1. The mounting block 32 is provided on the top of the frame body 31. The column 2 is connected to the bottom of the frame body 31. A plurality of through holes are opened on the mounting block 32. The sleeves 33 are all located on the inner bottom wall of the through holes. The push rod 34 is inserted into the sleeve 33 and is connected to the inner bottom wall of the sleeve 33 by a spring. The support block 35 is provided at the top of the push rod 34. Sliding grooves are opened on the side walls of the plurality of through holes. Both sides of the support block 35 are slidably connected to the adjacent sliding grooves. The connecting block 36 is provided on the top of the support block 35. The tops of the plurality of connecting blocks 36 are jointly installed with the mounting plate 37 by bolts. The bottom of the mounting plate 37 is connected to the pressing rod 38. One end of the pressing rod 38 is inserted into the frame body 31 and is connected to a contact block. A cam 39 is rotatably connected in the frame body 31. The single-slot pulley 310 is connected to the cam 39. The single-slot pulley 310 is in transmission connection with the driving component 6. Through the rotation of the cam 39 and the elastic contraction of the spring, the pressing rod 38 drives the mounting plate 37 and the roof support column 4 to perform continuous up-and-down jitter, thereby realizing the cleaning of the snow on the top, reducing the labor intensity of manually cleaning the snow on the top of the greenhouse, and improving the cleaning efficiency.

[0032] As shown in Figure 4As shown in the figure, the driving assembly 6 includes a connection box 61 and a cross plate 62. The connection box 61 is connected to the cross beam 1, and the cross plate 62 is connected inside the connection box 61 and divides the inside of the connection box 61 into an upper cavity and a lower cavity. A controller 63 is provided in the upper cavity, and a driving motor 64 is provided in the lower cavity. The controller 63 is electrically connected to the driving motor 64. A double-grooved pulley 65 is provided on the output shaft of the driving motor 64. Through grooves are provided on the connection box 61, the cross beam 1, and the frame body 31. A belt is provided in the through groove. The double-grooved pulley 65 is respectively drivingly connected to two adjacent single-grooved pulleys 310 through the belt. The double-grooved pulley 65 can synchronously drive the two single-grooved pulleys 310 to rotate, so as to realize synchronous rotation drive, improve the efficiency of shaking and the synchronism of shaking, and better realize the cleaning of snow accumulation.

[0033] As Figure 4 shown in the figure, the triggering assembly 9 includes a disc 91 and a plug rod 92. The plug rod 92 is slidably connected to the top of the connection box 61. One end of the plug rod 92 is connected to the bottom of the disc 91, and the other end of the plug rod 92 extends into the connection box 61 and is in the same position as the triggering button on the top of the controller 63. A support rod 93 is connected to the top of the disc 91. There are two support rods 93. One ends of the two support rods 93 are jointly connected to the roof support column 4. The weight of the accumulated snow squeezes the roof support column 4, the support frame 8, and the plug rod 92 to move downward, so that the bottom end of the plug rod 92 abuts against the triggering button on the controller 63, realizing the function of starting the driving motor 64 to drive the shaking assembly 3 to clean the snow, and avoiding the situation that personnel forget to clean.

[0034] As Figure 6 shown in the figure, the bottom of the support block 35 is arranged in a circular concave shape, which can improve the supporting force for the roof support column 4.

[0035] As Figure 1 shown in the figure, a plurality of support bars 5 arranged in an arc array are slidably provided on the roof support column 4. The sliding setting can facilitate the disassembly, replacement, and maintenance of the support bars 5.

[0036] The working principle of this utility model: When the snow accumulates on the roof to a certain weight, it pushes the roof support column 4 and the support block 35 to squeeze the spring, and the entire roof support column 4 descends. During the descending process of the roof support column 4, it drives the support rod 93, the disc 91, and the plug rod 92 to move downward. The bottom end of the plug rod 92 presses the button on the top of the controller 63. Due to the electrical connection relationship, the controller 63 powers on the driving motor 64, starts the driving motor 64, drives the double-grooved pulley 65 to rotate through the power output shaft of the driving motor 64, drives the adjacent single-grooved pulley 310 and the cam 39 to rotate through the transmission connection of the belt, and cooperates with the spring to connect the push rod 34 and the sleeve 33 and the relationship between the support block 35 and the inner sliding of the chute. The cam 39 rotates to toggle and press the lower lever 38 to perform lifting and shaking;

[0037] The pressing rod 38 drives the connecting block 36 and the shed top support column 4 to vibrate. When the shed top support column 4 vibrates, the snow on the top of the shed is affected by the vibration and can slide along the arc-shaped inclination of the shed top, thereby realizing the cleaning of the snow.

[0038] Only some exemplary embodiments of the present invention have been described by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
