Description

Technical Field

[0001] The utility model relates to the technical field of preventing farmland machine wells from falling, in particular to a field agricultural machine well anti-falling device. Background Art

[0002] In many rural areas, a large number of farmland irrigation wells are scattered among the fields. Some of the wells have been abandoned for many years without any warning signs. Children and livestock fall into the wells from time to time. In addition, since the diameter of the wellhead of the farmland irrigation well is small, casualties are often caused due to the difficulty and time of rescue after a fall accident, causing irreparable harm to the families of the accident victims. In the prior art, in order to solve the above problems, a woven net is generally set in the farmland well for protection. During the use of such a structural design, the woven net is often used for a long time and has poor bearing strength. Once a person or livestock mistakenly enters the well, the anti-fall net will be directly crushed and broken, and there is still a great safety hazard. Utility Model Content

[0003] Therefore, the purpose of the utility model is to provide a field agricultural machine well anti-fall device, through the mutual cooperation of the anti-fall component and the spare protection component, to achieve double support and double protection when in use, to avoid the protection frame falling and separating from the agricultural machine well due to direct impact of gravity, and also to avoid the situation where the anti-fall mesh frame is unable to bear weight due to aging, causing people or livestock to fall into the agricultural machine well.

[0004] In order to solve the above technical problems, according to one aspect of the utility model, the utility model provides the following technical solution: a field agricultural machine well anti-fall device, comprising:

[0005] An anti-falling assembly, the anti-falling assembly comprising an annular plate, an anti-falling mesh frame fixed to the bottom surface of the annular plate, a metal hook fixed to the top surface of the annular plate, and an annular groove opened in the farm machine well;

[0006] A spare protection component includes a threaded long rod fixed on the bottom surface of the annular plate, an anti-falling mesh plate arranged below the anti-falling mesh frame, a first circular hole opened on the top surface of the anti-falling mesh plate, and a threaded ring connected to the threaded long rod.

[0007] As a preferred solution of the field agricultural machine well anti-falling device described in the utility model, there are a plurality of metal hooks, and the plurality of metal hooks are distributed in a ring shape;

[0008] Wherein, the metal hook is hooked with the outer frame of the farm well.

[0009] As a preferred solution of the field agricultural machine well anti-falling device described in the utility model, the bottom surface of the annular plate and the top surface of the annular groove are in contact with each other, and the annular groove supports the annular plate.

[0010] As a preferred solution of the field agricultural machine well anti-falling device described in the utility model, wherein the threaded long rods are provided with three, and the three threaded long rods are distributed in a triangular shape;

[0011] Wherein, each position of the threaded long rod is provided with a corresponding threaded ring.

[0012] As a preferred solution of the anti-fall device for a field agricultural machine well described in the utility model, it also includes a limiting component, which includes a second circular hole opened in the agricultural machine well, a third circular hole opened in the frame of the anti-fall mesh plate and a limiting long rod inserted into the third circular hole.

[0013] As a preferred solution of the field agricultural machine well anti-falling device described in the utility model, the limiting long rod moves forward along the third circular hole, and the limiting long rod and the first circular hole are mutually fitted.

[0014] Compared with the prior art, the advantages of the utility model are:

[0015] 1. The utility model achieves double support and double protection when in use through the cooperation of the anti-fall component and the spare protection component, thereby preventing the protection frame from falling and detaching from the farm machine well due to direct impact of gravity, and also preventing people or livestock from falling into the farm machine well due to the aging of the anti-fall mesh frame and its inability to bear weight.

[0016] 2. Based on the first beneficial effect, the spare anti-fall mesh plate is limited for the second time through the setting of the limit component to prevent the spare anti-fall mesh plate from being hit and detached when subjected to gravity, thereby ensuring the stability of the anti-fall device.

[0017] During actual use, the user places the annular plate in the farm machine well, and makes the annular plate and the annular groove fit each other, so that the annular groove supports the annular plate. At this time, the metal hook is directly hooked on the outside of the farm machine well, so that the metal hook and the annular groove bear the weight at the same time, forming a double support, to prevent the annular plate from falling directly into the farm machine well under the force, and when people or livestock fall into the anti-fall mesh frame, if the anti-fall mesh frame breaks due to long-term use and load-bearing capacity, the anti-fall mesh plate is used as a backup protection to further prevent falling into the well accident. The user can rotate the threaded ring, and the threaded ring can be threaded on the threaded long rod. In this way, the operator can freely choose the height of the anti-fall mesh plate according to actual needs, so as to provide better secondary protection. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The utility model provides a device for preventing a field agricultural machine well from falling. By cooperating with an anti-fall component and a spare protection component, double support and double protection are formed when in use, so as to avoid a situation in which a protection frame falls and separates from the agricultural machine well due to a direct impact of gravity, and also avoid a situation in which a person or livestock falls into the agricultural machine well due to the inability to bear weight caused by aging of the anti-fall mesh frame.

[0028] Example 1

[0029] Figure 1 , Figure 2 , Figure 3 The figure shows the overall structure of an embodiment of a field agricultural well anti-fall device of the utility model. Figure 1 , Figure 2 , Figure 3 The main structure of this embodiment includes: an anti-fall component and a spare protection component.

[0030] The anti-falling assembly is used for double support to prevent the annular plate 11 from falling off. Specifically, the anti-falling assembly includes a set annular plate 11, an anti-falling mesh frame 12 fixed to the bottom surface of the annular plate 11, a metal hook 13 fixed to the top surface of the annular plate 11, and an annular groove 14 opened in the farm well;

[0031] During actual use, the user places the annular plate 11 in the farm machine well, and makes the annular plate 11 and the annular groove 14 fit each other, so that the annular groove 14 supports the annular plate 11. At this time, the metal hook 13 is directly hooked on the outside of the farm machine well, so that the metal hook 13 and the annular groove 14 bear the weight at the same time, forming a double support, thereby preventing the annular plate 11 from falling directly into the farm machine well under the force.

[0032] The spare protection component is used for secondary protection to avoid the problem that the anti-falling mesh frame 12 is powdered and affects the supporting strength. Specifically, the spare protection component includes a threaded long rod 21 fixed to the bottom surface of the annular plate 11, an anti-falling mesh plate 22 arranged below the anti-falling mesh frame 12, a first circular hole 23 opened on the top surface of the anti-falling mesh plate 22, and a threaded ring 24 connected to the threaded long rod 21;

[0033] When a person or livestock falls into the anti-fall mesh frame 12, if the anti-fall mesh frame 12 breaks due to poor load-bearing capacity after long-term use, the anti-fall mesh plate 22 is used as a backup protection to further prevent falling into the well. The user can rotate the threaded ring 24, and the threaded ring 24 can be threaded on the threaded long rod 21. In this way, the operator can freely choose the height of the anti-fall mesh plate 22 according to actual needs, so as to provide better secondary protection.

[0034] Example 2

[0035] Please refer to Figure 2and Figure 3 , through the setting of the limit component, the spare anti-falling mesh plate 22 is secondary limited to avoid the spare anti-falling mesh plate 22 from being knocked out when subjected to gravity, thereby ensuring the stability of the anti-falling;

[0036] Specifically, it also includes a limiting component, which includes a second circular hole 31 opened in the farm well, a third circular hole 32 opened in the frame of the anti-fall mesh plate 22, and a limiting long rod 33 inserted into the third circular hole 32;

[0037] During actual use, the limiting long rod 33 moves forward along the third circular hole 32, and the limiting long rod 33 and the first circular hole 23 are fitted together, so that the anti-falling mesh plate 22 is limited from three directions by the limiting long rod 33. In this way, combined with the threaded ring 24, the anti-falling mesh plate 22 can also form a secondary load-bearing limit to avoid separation.

[0038] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
