[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-6 The utility model describes the above technical solution in detail through the following embodiments:

[0028] like Figure 1-Figure 6 As shown, a glass greenhouse top slope adjustment mechanism includes a glass greenhouse frame 1 and two glass roofs 6, a vertical plate 2 is provided on the top steel frame of the glass greenhouse frame 1, a top frame 3 is provided on the top of the vertical plate 2, a lifting mechanism 4 is provided on the vertical plate 2 and the top frame 3, two symmetrically arranged fixed plates 11 are provided on the lifting mechanism 4, side sliding grooves are provided on the side walls of the fixed plates 11, limiting blocks 13 are provided for sliding in the side sliding grooves, side plates 12 are provided on the limiting blocks 13, and a shaking mechanism 9 is provided directly below the side plates 12, and a limiting mechanism 5 for limiting the side plates 12 is provided at the bottom of the top frame 3, one end of all the glass roofs 6 are connected to one end side wall of the glass greenhouse frame 1, the other end of the glass roof 6 is hinged to the side plate 12, and the shaking mechanism 9 is in contact with the bottom of the side plate 12.

[0029] The transmission mechanism 4 starts and drives the lifting mechanism 5 and the shaking mechanism 9 to lift and lower synchronously, so that the shaking mechanism 9 engages with the tooth grooves on the rack 10 through the tooth roller 92 during lifting and lowering, and makes the tooth roller 92 rotate, thereby driving the shaking mechanism 9 to rotate, and the elastic force of the second spring at the bottom of 13 contracts, so that the bottom of 12 and the shaking mechanism 9 are in conflict with each other, and 12 has a certain elasticity. When the shaking mechanism 9 rotates, it pushes 12 to lift and shake, and the shaking is transmitted to the surface of the glass ceiling 6, and the components cooperate and link with each other to realize the cleaning of snow. The lifting effect can improve the angle adjustment of the glass ceiling. When the inclination angle of the glass ceiling 6 is large, the snow can slide off more easily. When the inclination angle of the glass ceiling 6 is small, the lighting area of ​​the glass ceiling 6 can be increased to improve the lighting effect.

[0030] like Figure 2-Figure 3 As shown, the lifting mechanism 4 includes a driving gear 41, a driven gear 42 and a threaded rotating rod 43. The driving gear 41 and the driven gear 42 are both located at the top of the top frame 3, and the driving gear 41 is meshed with the driven gear 42. Through the meshing relationship, the servo motor 22 is started to transmit power to the threaded rotating rod 43, so that the threaded rotating rod 43 rotates synchronously, and the threaded rotating rod 43 is rotatably connected to the top frame 3. A groove is provided on the top of the vertical plate 2, and a servo motor 22 is provided in the groove. The power output shaft of the servo motor 22 is rotatably connected to the top frame 3. The driving gear 41 is connected to the power output shaft of the servo motor 22, and the threaded rotating rod 43 is connected to the bottom of the driven gear 42. A connecting plate 52 is threadedly connected to the outer wall of the threaded rotating rod 43. With the interaction between the threads, the rotation of the threaded rotating rod 43 can drive the connecting plate 52 to perform lifting and lowering operations. The sliding sleeve 53 is provided on one side of the connecting plate 52, wherein the sliding sleeve 53 can limit the position of the connecting plate 52 when it is lifted or lowered, so as to avoid the displacement of the connecting plate 52 when it is lifted or lowered. A plurality of through holes are provided on the sliding sleeve 53, and a first sliding groove is provided on the side walls of both sides of the vertical plate 2, and a plurality of positioning rods 21 that slide with the through holes are provided inside the two first sliding grooves. The sliding cooperation between the through holes and the positioning rods 21 can improve the stability during lifting and lowering, and the sliding sleeve 53 and the first sliding groove cooperate to avoid the displacement of the connecting plate 52 when it is lifted or lowered. The sliding sleeve 53 is located in the first sliding groove, and the other side of the connecting plate 52 is connected to the fixed plate 11. The side edge of the fixed plate 11 is connected to a parallel plate 8. When the parallel plate 8 is connected to 11, it can be lifted or lowered synchronously with 11, and the fit between the shaking mechanism 9 and the bottom of 12 is better guaranteed.

[0031] like Figure 6As shown, the shaking mechanism 9 includes a rotating rod 91, a gear roller 92, a cam 93 and a rack 10. The rotating rod 91 is rotatably connected to the parallel plate 8. The gear roller 92 is connected to the front end of the rotating rod 91. A plurality of cams 93 are provided. The plurality of cams 93 are connected to the outer side wall of the rotating rod 91. One end of the rack 10 is connected to the side edge of the vertical plate 2. The parallel plate 8 is connected to the side wall of the fixed plate 11. A plurality of square grooves are provided on the parallel plate 8. The rotating rod 91 is rotatably connected to the inner side walls of the plurality of square grooves. The cross section of the rack 10 is L-shaped. The other end of the rack 10 is connected to the top frame 3. A tooth groove is provided on the side wall of the rack 10 to cooperate with the tooth roller 92, and the tooth roller 92 is meshed with the tooth groove. Since the rack 10 is connected to the vertical plate 2, when the equipment is lifted or lowered, the vertical plate 2 and the rack 10 remain in position. When the parallel plate 8 is lifted or lowered, it can drive the tooth roller 92 to be lifted or lowered synchronously, and the tooth roller 92 is meshed with the tooth groove. At this time, the tooth roller 92 rotates when it moves up and down on the tooth groove. The rotation of the tooth roller 92 drives multiple cams 93 to rotate synchronously, and when it is in contact with the bottom of 12, it moves the bottom of 12 and produces a shaking effect.

[0032] like Figure 3 As shown, the limiting mechanism 5 includes a positioning plate 55, a sleeve 54 and an insertion rod 51. The positioning plate 55 is arranged at the bottom of the top frame 3, the sleeve 54 is arranged on the side plate 12, the insertion rod 51 is connected to the bottom of the top frame 3, the bottom end of the positioning plate 55 is located in the side slide groove, one end of the insertion rod 51 is inserted in the sleeve 54 and is connected to a sliding block, and a first spring is provided at the bottom of the sliding block, and the bottom end of the first spring is connected to the inner bottom wall of the sleeve 54. When 12 is lifted or lowered with the connecting plate 52, the position of the lifting plate 51 always remains stationary, and the elastic force of the first spring is pushed, thereby realizing the pushing of the sliding block 54 and 12 to generate a force squeezing toward the bottom, and the squeezing force can improve the fit between 12 and the shaking mechanism 9, and improve the stability of the shaking.

[0033] like Figure 5 As shown, telescopic rods 71 ​​are hinged on both sides of the glass greenhouse frame 1, and sliders 7 are hinged on the tops of the two telescopic rods 71. A second slide groove is provided at the bottom of the glass ceiling 6, and the slider 7 is slidably connected in the second slide groove. The telescopic effect of the telescopic rod 71 cooperates with the sliding effect of the telescopic component 7 in the slide groove, so that the glass ceiling 6 can be raised and lowered, thereby completing the function of shaking and clearing the snow.

[0034] like Figure 6 As shown, multiple cams 93 are arranged in a circular array with the center of the rotating rod 91 as the central axis. Since the multiple cams 93 are inclined at a certain angle at a time, when the multiple cams 93 rotate synchronously, they can push and knock the bottom of 12 in turn, and the knocking points on the bottom of 12 are transmitted from front to back in turn. Compared with the overall shaking, the knocking effect has a better cleaning effect.

[0035] like Figure 3 As shown, a second spring is provided at the bottom of the limit block 13, and the bottom end of the second spring is connected to the inner bottom wall of the side slide groove. The function of the second spring is consistent with that of the first spring, but in order to ensure that 12 can fit firmly with the shaking mechanism 9, the first spring and the second spring cooperate to improve the stability of the fit, ensure the effect of shaking cleaning, and avoid the situation where any spring becomes loose and affects the shaking effect.

[0036] Working principle: first start the servo motor 22, and drive the driving gear 41 to rotate through the power output shaft of the servo motor 22. In conjunction with the meshing setting relationship between the two driven gears 42, the rotation of the driving gear 41 drives the two driven gears 42 and the threaded rotating rod 43 to rotate. In conjunction with the interaction between the threads and the limiting effect of the positioning rod 21 on the sliding sleeve 53, the rotation of the threaded rotating rod 43 drives the connecting plate 52 and the fixed plate 11 and the side plate 12 connected to the connecting plate 52 to rise and fall synchronously. During the lifting and lowering, the tooth roller 92 meshes and rotates on the rack 10, and drives multiple cams 93 to rotate synchronously. When the multiple cams 93 rotate, they push the glass ceiling 6 to shake slightly up and down, so that the snow accumulated on the top of the glass ceiling 6 can slide to the ground along the inclined surface at the top of the glass ceiling 6 through the shaking generated by the linkage during the lifting and lowering process.
