Description

Technical Field

[0001] This utility model relates to the field of livestock breeding equipment technology, and in particular to a livestock breeding roller shutter device. Background Technology

[0002] In the process of animal husbandry, ventilation and lighting in livestock sheds are extremely important factors. Good ventilation can promptly remove polluted air from the sheds, such as carbon dioxide exhaled by livestock and ammonia produced by feces, and introduce fresh air, creating a healthy and comfortable breathing environment for livestock, which can effectively reduce the incidence of respiratory diseases and promote their metabolism.

[0003] Traditional methods of opening and closing livestock shed doors and windows have many inconveniences. The operation of manually opening and closing doors and windows is lengthy and complicated. Farmers need to push and pull them themselves, and each opening and closing requires a lot of manpower. Especially in large-scale farms, the operation of many livestock shed doors and windows can make the staff exhausted. Moreover, this process is extremely time-consuming and seriously affects work efficiency.

[0004] However, some existing rolling shutter devices also have problems such as complex structure, poor stability, weak wind resistance, and difficulty in adapting to different livestock house specifications and breeding environment requirements.

[0005] Therefore, this utility model proposes a rolling shutter device for livestock breeding. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies and propose a livestock breeding roller shutter device.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a livestock breeding roller shutter device, comprising:

[0008] The drive assembly consists of a drive motor and a roller mounting frame. A guide wheel is rotatably connected to the roller mounting frame, and a threaded mounting seat is provided on the side of the roller mounting frame away from the drive motor.

[0009] The wire is wound and mounted on the wire reel;

[0010] Mounting rod assembly; The mounting rod assembly consists of a positioning rod inserted into a threaded mounting base and a tightening sleeve. The positioning rod is provided with an expansion sleeve. There are three expansion sleeves in total, and the spacing between two adjacent expansion sleeves is equal. The three expansion sleeves are provided with fault tolerance holes.

[0011] In a preferred embodiment, the positioning rod has a threaded groove on the side near the threaded mounting seat, and the positioning rod is threadedly connected to the threaded mounting seat through the threaded groove.

[0012] The beneficial effect of adopting the above-mentioned further solution is that, under the action of the expansion sleeve, the positioning rod and the threaded mounting seat are separated into two parts. The advantage of the separate part is that when installing the curtain, the positioning rod and the tightening sleeve are first inserted into the bottom sleeve of the curtain. After the installation is completed, the positioning rod is threaded into the threaded mounting seat for fixation.

[0013] In a preferred embodiment, the fault-tolerant holes are arranged in a ring, and the included angle between two adjacent fault-tolerant holes is equal.

[0014] The beneficial effect of adopting the above-mentioned further solution is that, under the action of the fault-tolerant hole, when the tightening sleeve is sleeved on the outside of the positioning rod, it deforms and shrinks inward through the fault-tolerant hole, thereby changing the diameter of the expansion sleeve, so that the expansion sleeve is embedded inside the tightening sleeve.

[0015] In a preferred embodiment, the diameter of the tightening sleeve is larger than the diameter of the positioning rod, and the diameter of the tightening sleeve is smaller than the diameter of the expansion sleeve.

[0016] The beneficial effect of adopting the above-mentioned further solution is that, under the action of tightening sleeve, the expansion sleeve is squeezed and contracted, and the positioning rod is further inserted into the bottom of the curtain through tightening sleeve, so as to avoid the expansion sleeve getting stuck with the curtain, which would prevent the positioning rod from being fully inserted into the bottom of the curtain.

[0017] In a preferred embodiment, a push plate is provided on the side of the tightening sleeve away from the threaded mounting seat.

[0018] The beneficial effect of adopting the above-mentioned further solution is that, under the action of the push plate, after the positioning rod is installed, the tightening sleeve is pulled out from the bottom of the curtain by the push plate. After the tightening sleeve is pulled out from the bottom of the curtain, the bottom of the curtain is expanded and filled under the action of the expansion sleeve, so as to prevent the curtain from shifting left and right on the positioning rod during use.

[0019] In a preferred embodiment, the top of the roller mounting bracket is provided with an upper limit seat, and the upper limit seat is rotatably connected to limit rollers on both sides of the guide wire.

[0020] The beneficial effects of adopting the above-mentioned further solution are: under the action of the upper limit seat, the conductor is limited, avoiding large displacement during the winding process and preventing the conductor from failing to be wound onto the conductor wheel during winding.

[0021] In a preferred embodiment, a mounting bracket is provided on one side of the roller mounting bracket, and the mounting bracket and the roller mounting bracket are connected by bolts.

[0022] The advantages of adopting the above-mentioned further solution are: the roller mounting bracket and the mounting frame are separate structures. The advantage of this structure is that during use, the mounting frame can be fixed to the wall first, and then the roller mounting bracket can be fixed with bolts. In addition, during later maintenance, the mounting frame can be directly removed from the roller mounting bracket.

[0023] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0024] In this invention, the tightening sleeve acts as a compression limit on the expansion sleeve, preventing the positioning rod from being unable to complete the insertion work due to excessive friction between the expansion sleeve and the bottom of the curtain when it is inserted into the bottom of the mattress. After the positioning rod is inserted into the bottom of the curtain, the tightening sleeve is pulled out by the push plate. At this time, the expansion sleeve loses the compression force and re-deforms and recovers, performing segmented expansion and positioning of the bottom of the curtain, thus preventing the curtain from shifting left and right on the positioning rod during use.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] like Figure 1-4 As shown, this utility model provides a technical solution: a livestock breeding roller shutter device, comprising:

[0036] Drive assembly 1 consists of drive motor 11 and roller mounting bracket 12. A guide wheel 13 is rotatably connected to the roller mounting bracket 12. A threaded mounting seat 14 is provided on the side of the roller mounting bracket 12 away from the drive motor 11.

[0037] The guide wire 2 is wound around the guide wheel 13 and connects the guide wheel 13 to the curtain. When the guide wheel 13 rotates, it can drive the curtain to roll up.

[0038] Mounting rod assembly 4; Mounting rod assembly 4 consists of a positioning rod 41 inserted into the threaded mounting base 14 and a tightening sleeve 44. The positioning rod 41 is provided with an expansion sleeve 43. There are three expansion sleeves 43, and the distance between two adjacent expansion sleeves 43 is equal. The three expansion sleeves 43 are provided with fault tolerance holes 431. The fault tolerance holes 431 are distributed in a ring, and the included angle between two adjacent fault tolerance holes 431 is equal. The diameter of the tightening sleeve 44 is larger than the diameter of the positioning rod 41, and the diameter of the tightening sleeve 44 is smaller than the diameter of the expansion sleeves 43. A push plate 4 is provided on the side of the tightening sleeve 44 away from the threaded mounting base 14. 41. A mounting bracket 32 ​​is provided on one side of the roller mounting bracket 12. The mounting bracket 32 ​​is connected to the roller mounting bracket 12 by bolts. Under the action of the tightening sleeve 44, the expansion sleeve 43 is squeezed and limited, so as to avoid the positioning rod 41 being unable to complete the insertion work due to the large friction between the expansion sleeve 43 and the bottom of the curtain when it is inserted into the bottom of the mattress. After the positioning rod 41 is inserted into the bottom of the curtain, the tightening sleeve 44 is pulled out by the push plate 441. At this time, the expansion sleeve 43 loses the squeezing force and re-deforms and recovers, performing segmented expansion and positioning of the bottom of the curtain, so as to prevent the curtain from shifting left and right on the positioning rod 41 during use.

[0039] The above solutions still have issues with the installation of the curtains and positioning rod 41, such as... Figure 4As shown: In this solution, the positioning rod 41 has a threaded groove 42 on the side near the threaded mounting seat 14. The positioning rod 41 is threadedly connected to the threaded mounting seat 14 through the threaded groove 42. Under the action of the expansion sleeve 43, the positioning rod 41 and the threaded mounting seat 14 are separated. The advantage of the separate structure is that when installing the curtain, the positioning rod 41 and the tightening sleeve 44 are first inserted into the bottom sleeve of the curtain. After installation, the positioning rod 41 is threaded into the threaded mounting seat 14 for fixation, so as to avoid the push plate 441 from blocking the curtain and preventing it from being inserted from the side of the push plate 441.

[0040] The above solution also has the problem of large displacement of conductor 2 during winding, such as... Figure 3 As shown: In this scheme, the top of the roller mounting bracket 12 is provided with an upper limit seat 3. The upper limit seat 3 is rotatably connected to the two sides of the wire 2. Under the action of the upper limit seat 3, the wire 2 is limited to avoid large displacement during the winding process of the wire 2, and to prevent the wire 2 from being unable to be wound on the wire wheel 13 during winding.

[0041] Working principle:

[0042] like Figure 1-4 As shown, first, the mounting bracket 32 ​​is installed and fixed in the designated position. Then, the positioning rod 41 and the tightening sleeve 44 are inserted into the bottom limiting sleeve of the curtain. Subsequently, the roller mounting bracket 12 is fixed on the mounting bracket 32. The positioning rod 41 and the threaded mounting seat 14 are then threaded together through the threaded groove 42. After the fixing is completed, the tightening sleeve 44 is pulled out through the push plate 441. When the tightening sleeve 44 is pulled out, the expansion sleeve 43 loses the squeezing force and, under the action of the fault hole 431, re-deforms and expands, expanding and positioning the sleeve at the bottom of the curtain to prevent the curtain from shifting left and right on the positioning rod 41 during use. After the installation is completed, the wire 2 is passed through the guide wheel set above the curtain and connected to the curtain. After the connection is completed, the wire wheel 13 is driven to rotate through the hole drive motor 11, so that the wire wheel 13 drives the wire 2 to roll up, thereby realizing the curtain rolling function.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
