[0020] 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.

[0021] like Figure 1 and Figure 4An agricultural greenhouse shown in the figure comprises a greenhouse support 1 and a snow removal device; the top of the greenhouse support 1 is a triangle 3, and the snow removal device is installed on the top of the greenhouse; the snow removal device comprises a snow scraper 14 and a telescopic snow guard 2; the telescopic snow guard 2 comprises a telescopic driver 7 and a pull-out baffle 15; the pull-out baffle 15 is a plurality of mutually nested rectangular parallelepipeds, which gradually shrink from the outside to the inside and can be completely retracted into the outermost baffle; the telescopic driver 7 is located on both sides of the pull-out baffle 15, and the side of the pull-out baffle 15 is provided with a sliding track for the movement of the telescopic driver 7; a positioning plate 5 is provided at the front end of the telescopic driver 7; the snow scraper 14 is located on the top of the telescopic snow guard 2, and comprises a telescopic rod 12 and an arc scraper 8; compared with the flat arc scraper, it has better accommodating space and can scrape off relatively thick snow.

[0022] The telescopic drive 7 is connected to the motor and the reducer 13, and the positioning plate 5 is welded to the innermost baffle 6 of the pull-out baffle. The structure of the telescopic drive 7 can refer to the electric telescopic staircase structure, and the principles of the two are similar: a synchronous belt transmission method is adopted, and the motor drives the axial rotation, which is transmitted to the synchronous belt through the reducer, so that the telescopic bracket can be telescoped on the track; the operator can control the start of the telescopic drive 7 through the remote control switch to ensure that when the telescopic drive 7 is started, the positioning plate 5 drives the pull-out baffle 15 to extend downward.

[0023] The cross section of the positioning plate 5 is L-shaped, and the length thereof is equal to the overall thickness of the pull-out baffle 15 , and the entire pull-out baffle 15 can be effectively pulled when contracted.

[0024] The telescopic snow guard 2 has a smooth surface and can cover the entire shed roof with excess extended parts when fully extended; the excess extended parts can prevent the sliding snow from damaging the greenhouse films on both sides, so as to protect the entire agricultural greenhouse.

[0025] like Figure 5 As shown, the bottom of the arc scraper 8 is made of rubber material 10, and the upper part is made of rigid metal material 11; the rubber 10 at the bottom can avoid scratching the surface of the pull-out baffle, and can also better contact with the pull-out baffle to ensure the working quality of the snow scraper.

[0026] The automatic telescopic rod comprises a retracting rod 12 and a driving motor 9, and the driving motor 9 is controlled by a manual switch inside the greenhouse; the automatic telescopic rod is a prior art, and its working principle is based on a motor drive and a spiral combined transmission structure; in different applications, the combined structure of the automatic telescopic rod will be adjusted; it is usually composed of a telescopic rod shell, an inner core, a guide member, a tensile member and a bracket; in detail, the outer side of the inner core of the electric telescopic rod is wrapped with a slidable guide member; when the motor is started, the inner core moves toward the center of the telescopic rod shell, and also drives the movement of the guide member; and the guide member is responsible for controlling the length and direction of the telescopic rod; at the same time, the guide member can also convert the tension or pressure applied to the rod by the outside into a complex axial force, thereby better maintaining and enhancing the stability and carrying capacity of the telescopic rod; the automatic retracting rod can push the arc scraper 8 to move, thereby achieving the purpose of snow removal.

[0027] The greenhouse support 1 is a combination of a triangular support 3 and a square support 4 formed by welding or screwing multiple steel materials; the outside of the greenhouse support is covered with a plastic film; the plastic film is a special film for greenhouses and can be purchased by the user according to the planting effect.

[0028] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
