Technical Field

[0001] The utility model relates to the technical field of guardrails, and more specifically, to a warning guardrail for a farm. Background Technique

[0002] The warning guardrail for a farm is a facility used to protect the safety of animals and plants in the farm and prevent the intrusion of outsiders or animals. It is usually made of metal or plastic and has a certain height and strength to prevent unauthorized personnel or animals from entering the breeding area. According to the specific needs and budget of the farm, different guardrail materials can be selected, such as metal, plastic or wood. Metal guardrails have high strength and durability, but are expensive; plastic guardrails have lower costs, but may not be as strong as metal guardrails; wooden guardrails are easily affected by environmental factors and require regular maintenance.

[0003] In the prior art, in order to prevent young animals from trying to jump or climb over the guardrail and causing injuries, the height of the guardrail during the young animal period is set relatively low. However, as the breeding cycle increases, the size of the animals in the farm also increases. At this time, in order to facilitate management, the guardrail needs to be heightened. When commonly heightening the guardrail, the original guardrail is directly removed and a higher guardrail is installed at the same position, and the time and cost consumed for replacement are relatively high. How to invent a warning guardrail for a farm to improve these problems has become an urgent problem to be solved by those skilled in the art. Content of the Utility Model

[0004] To make up for the above deficiencies, the utility model provides a warning guardrail for a farm, aiming to improve the problem that when commonly heightening the guardrail, the original guardrail is directly removed and a higher guardrail is installed, and the time and cost consumed are relatively high.

[0005] The utility model is implemented as follows:

[0006] The utility model provides a warning guardrail for a farm, which includes a main guardrail and an extended mesh fence arranged on the main guardrail. An extended groove is opened at the upper end of the main guardrail, and mesh fences are installed on the inner walls of both sides of the extended groove. Symmetric guide grooves and two groups of adjustment grooves are opened on the outer wall of the upper end of the main guardrail. Symmetric drive grooves are opened inside both sides of the main guardrail. Drive gears, a driving gear and two driven gears are respectively installed on the inner walls of the drive grooves. A fixed sleeve is fixedly connected to the outer wall of one side of the main guardrail, and two symmetric limiting semi-rings are fixedly connected to the inner wall of the fixed sleeve;

[0007] A positioning plate that overlaps with the upper end of the main guardrail is fixedly connected above the extended mesh fence. A guide rod that is slidably connected to the inner wall of the guide groove is fixedly connected to the outer wall below the positioning plate. A rack that is slidably connected to the inner wall of the adjustment groove is fixedly connected to the outer wall of the positioning plate close to the guide rod.

[0008] Preferably, both ends of the driving gear, the driving gear and the driven gear are respectively rotatably connected to the inner wall of the driving groove, and transmission grooves are formed on the outer walls of the driving gear, the driving gear and the driven gear.

[0009] Preferably, the driving gear and the driving gear are meshed and connected, a first transmission belt is connected between the transmission grooves of the driving gear and one end of the driven gear, and a second transmission belt is connected between the transmission grooves of the driving gear and the other end of the driven gear.

[0010] Preferably, the outer wall of the extension fence is slidably connected to the inner wall of the extension groove, and the outer wall of the rack is meshed with the outer wall of the driven gear.

[0011] By adopting the above technical solution, as the growth cycle changes, the livestock body size in the farm correspondingly increases. At this time, by rotating the driving gear to drive the driven gears at both ends, and cooperating with the racks on both sides of the lower end of the positioning plate, the extension fence moves upward, thereby changing the height of the entire guardrail and preventing the livestock from jumping out of the guardrail due to too low guardrail height.

[0012] Preferably, one end of one of the driving gears is fixedly connected with an adjusting shaft, symmetric sliding grooves are formed on the outer wall of the adjusting shaft, a spring is fixedly connected to the upper end of the adjusting shaft, and a regular hexagon fixing block is fixedly connected to one side wall of the spring.

[0013] Preferably, one end of the fixing block is fixedly connected with an adjusting sleeve slidably connected to the outer wall of the adjusting shaft, a slider slidably connected to the sliding groove is fixedly connected to the inner wall of the adjusting sleeve, the slider can slide through the gap between the two limiting half rings, and the outer wall of the adjusting sleeve is rotatably connected to the inner wall of the fixing sleeve.

[0014] By adopting the above technical solution, after the height of the extension fence is adjusted, at this time, pull the fixing block to stretch the spring and move upward until the slider on the inner wall of the adjusting sleeve passes through the two limiting half rings, then rotate the adjusting block so that the two sliders are respectively placed on the limiting half rings, and under the action of the spring restoring force, the slider is closely attached to the limiting half ring, thereby fixing the adjusting shaft and preventing the extension fence from sliding due to accidental touch.

[0015] The beneficial effects of the present utility model are:

[0016] By installing wire fences on the inner walls on both sides of the main fence, the protective effect of the entire fence is improved. At the same time, the extension wire fence installed in the extension groove opened at the upper end of the main fence, in cooperation with the adjustment mechanism arranged in the drive groove, can realize the adjustment of the height of the extension fence, and the set fixing mechanism fixes the extension fence after adjustment to prevent it from sliding and affecting the height adjustment effect. The set warning fence can adjust the height of the fence according to the size of livestock, eliminating the need for multiple replacements, thus saving the time and cost of replacing the fence.

Detailed implementation mode

[0025] To make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present utility model.

[0026] Example, refer to Figures 1 - 6 , a warning guardrail for a farm, including a main guardrail 1 and an extended wire mesh fence 22 arranged on the main guardrail 1. An extension groove 2 is opened at the upper end of the main guardrail 1. Wire meshes 3 are installed on the inner walls on both sides of the extension groove 2. Symmetric guide grooves 4 and two groups of adjustment grooves 5 are opened on the outer wall at the upper end of the main guardrail 1. Symmetric drive grooves 6 are opened inside both sides of the main guardrail 1. Drive gears 9, driving gears 10 and two driven gears 11 are respectively installed on the inner walls of the drive grooves 6. A fixed sleeve 7 is fixedly connected to the outer wall of one side of the main guardrail 1. Two symmetric limit half-rings 8 are fixedly connected to the inner wall of the fixed sleeve 7;

[0027] A positioning plate 21 that overlaps with the upper end of the main guardrail 1 is fixedly connected above the extended wire mesh fence 22. A guide rod 24 that is slidably connected to the inner wall of the guide groove 4 is fixedly connected to the outer wall below the positioning plate 21. A rack 23 that is slidably connected to the inner wall of the adjustment groove 5 is fixedly connected to the outer wall of the positioning plate 21 close to the guide rod 24.

[0028] Furthermore; both ends of the drive gear 9, the driving gear 10 and the driven gear 11 are respectively rotatably connected to the inner wall of the drive groove 6. Transmission grooves 12 are opened on the outer walls of the drive gear 9, the driving gear 10 and the driven gear 11. The drive gear 9 and the driving gear 10 are meshed and connected. A first transmission belt 13 is connected between the transmission grooves 12 of the drive gear 9 and one end of the driven gear 11. A second transmission belt 14 is connected between the transmission grooves 12 of the driving gear 10 and the other end of the driven gear 11. The outer wall of the extended wire mesh fence 22 is slidably connected to the inner wall of the extension groove 2. The outer wall of the rack 23 is meshed and connected to the outer wall of the driven gear 11.

[0029] It should be noted that as the growth cycle of livestock changes, the body size of the livestock increases accordingly. At this time, by rotating the driving gear 9 to engage with the driving gear 10 and rotate simultaneously, the first transmission belt 13 on the transmission groove 12 of the driving gear 9 cooperates with the driven gear 11 at one end to make it rotate. At the same time, the driven gear 11 at the other end rotates simultaneously under the cooperation of the second transmission belt 14 and the driving gear 10. During the rotation, the rack 23 on the positioning plate 21 on one side is engaged to make it slide, and at the same time, the extension fence 22 is driven to slide upward, so as to increase the height of the entire guardrail and prevent the livestock from jumping out of the guardrail due to the too low height of the guardrail.

[0030] Furthermore, one end of the driving gear 9 on one side is fixedly connected with an adjusting shaft 15. Symmetric sliding grooves 16 are formed on the outer wall of the adjusting shaft 15. The upper end of the adjusting shaft 15 is fixedly connected with a spring 17. One side wall of the spring 17 is fixedly connected with a regular hexagon fixing block 18. One end of the fixing block 18 is fixedly connected with an adjusting sleeve 19 that is slidably connected to the outer wall of the adjusting shaft 15. The inner wall of the adjusting sleeve 19 is fixedly connected with a slider 20 that is slidably connected to the sliding groove 16. The slider 20 can slide through the gap between the two limiting half-rings 8. The outer wall of the adjusting sleeve 19 is rotatably connected to the inner wall of the fixing sleeve 7.

[0031] It should be noted that after the height adjustment of the extension fence 22 is completed, at this time, the fixing block 18 is pulled to stretch the spring 17 and move upward until the slider 20 on the inner wall of the adjusting sleeve 19 passes through the two limiting half-rings 8. Then, the fixing block 18 is rotated to drive the two sliders 20 on the inner wall of the adjusting sleeve 19 to rotate, so that the slider 20 is placed on the limiting half-ring 8. At this time, when the hand is released, under the action of the restoring force of the spring 17, the slider 20 is closely attached to the limiting half-ring 8, so that the lower adjusting shaft 15 is fixed to prevent the extension fence 22 from sliding due to accidental contact with the adjusting shaft 15.

[0032] The working principle of this kind of warning guardrail for a farm:

[0033] When it is necessary to extend the height of the guardrail, pull the fixed block 18 and then rotate it to make the notch between the slider 20 on the inner wall of the adjusting sleeve 19 and the limit semi-ring 8 vertical. At this time, release the fixed block 18 so that the slider 20 on the inner wall of the adjusting sleeve 19 is inserted into the chute 16 on the outside of the adjusting shaft 15 to keep it fixed. Then, use a hex key to turn the fixed block 18 to drive the adjusting shaft 15 to rotate. At the same time, the adjusting shaft 15 drives the driving gear 9 to rotate. The driving gear 9 rotates while meshing with the driving gear 10. The first transmission belt 13 on the transmission groove 12 of the driving gear 9 cooperates with the driven gear 11 at one end to make it rotate. At the same time, the driven gear 11 at the other end rotates simultaneously under the cooperation of the second transmission belt 14 and the driving gear 10. During the rotation, it meshes with the rack 23 on the positioning plate 21 on one side to make it slide, and at the same time drives the extension net fence 22 to slide upward. After the height adjustment is completed, pull the fixed block 18 to move the tension spring 17 upward until the slider 20 on the inner wall of the adjusting sleeve 19 passes through the two limit semi-rings 8. Then, rotate the fixed block 18 to drive the two sliders 20 on the inner wall of the adjusting sleeve 19 to rotate, so that the sliders 20 are placed on the limit semi-rings 8. At this time, release the hand, and under the action of the restoring force of the spring 17, the sliders 20 are closely attached to the limit semi-rings 8, fixing the lower adjusting shaft 15 to prevent accidental contact with the adjusting shaft 15 from causing the sliding of the extension net fence 22, thereby realizing the adjustment of the height of the guardrail.

[0034] It should be noted that the specific model and specifications of the motor need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0035] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
