Description

Technical Field

[0001] The utility model relates to the technical field of agricultural auxiliary tools, in particular to a cement pole lifter. Background Art

[0002] In current orchard management, rural field planning, and temporary fence construction, cement poles are widely used as supporting structures due to their durability and low cost. They are used in conjunction with wire mesh and other materials to form effective enclosure systems. However, when these concrete poles need to be replaced, repaired, or their layout adjusted, problems arise. Because the concrete poles are deeply embedded in the soil, manual removal is almost impossible, and excavation with large machinery such as excavators is usually required.

[0003] However, in practice, using an excavator to remove just a few concrete poles is not only complex and time-consuming, but also expensive, placing a significant financial burden on small farmers and orchard managers. Furthermore, excavator operations can cause unnecessary damage to surrounding soil and vegetation, impacting the ecological environment.

[0004] Therefore, there is an urgent need for an economical and efficient rod-pulling tool that can be manually operated to easily pull the cement rod out of the soil. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a cement pole lifter.

[0006] The technical problem to be solved by the present invention is achieved by the following technical solutions:

[0007] A cement pole lifter includes a base, a support pole, an insertion pole and a pressure pole. The support pole is vertically fixed on the base. A first ear ring is welded to the side of the upper end of the support pole. The pressure pole is located at the upper end of the support pole, and a second ear ring is welded to the lower front end of the pressure pole. The second ear ring is sleeved with the first ear ring.

[0008] The front end of the pressure rod is provided with an opening, a U-shaped ear portion is welded at the opening, and through holes are provided at both ends of the U-shaped ear portion.

[0009] The insertion rod is an integrated type including a rotating part and a U-shaped insertion rod. The rotating part is provided with a rotating hole. The insertion rod is fixed on the U-shaped ear part through the rotating hole and the through hole with bolts and nuts.

[0010] The U-shaped insertion rod of the insertion rod is used for inserting into the cement pole.

[0011] The insertion rod can be replaced according to the actual width of the cement pole.

[0012] Beneficial effects of the utility model:

[0013] This utility model's cement pole puller allows for easy removal of cement poles through manual operation, eliminating the need for large-scale machinery such as excavators, significantly reducing operating costs. Its operating principle is based on the lever principle, whereby the pressure exerted by the pressure rod on the inserted pole transfers force to the cement pole, allowing for easy removal. This makes it more economical and affordable for small farmers or orchard managers.

[0014] By rationally designing the base, support rod, insertion rod and pressure rod structure and utilizing the lever principle, the rod lifting process is smoother and manual operation is easier. Simply insert the insertion rod under the cement pole and then apply pressure through the pressure rod to pull out the cement pole, thereby improving work efficiency.

[0015] The rod part is designed as a replaceable structure, which can be adjusted according to the actual width of the cement pole. By replacing rods of different sizes, it can adapt to cement poles of different specifications, thereby enhancing the versatility and adaptability of the rod lifter.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0019] A cement pole lifter includes a base 1, a support pole 2, an insertion pole 3 and a pressure pole 4. The support pole 2 is vertically fixed on the base 1. A first ear ring 5 is welded to the side of the upper end of the support pole 2. The pressure pole 4 is located at the upper end of the support pole 2, and a second ear ring 6 is welded to the lower front end of the pressure pole 4. The second ear ring 6 is sleeved with the first ear ring 5.

[0020] The front end of the pressure rod 4 is provided with an opening, a U-shaped ear portion 7 is welded to the opening, and through holes are provided at both ends of the U-shaped ear portion 7.

[0021] The insertion rod 3 is an integrated type including a rotating portion 8 and a U-shaped insertion rod 9. The rotating portion 8 is provided with a rotating hole. The insertion rod 3 is fixed to the U-shaped ear portion 7 through the rotating hole and the through hole with a bolt 10 and a nut 11.

[0022] The U-shaped insertion rod 9 of the insertion rod 3 is used to be inserted into the cement pole 12 .

[0023] The insertion rod 3 can be replaced according to the actual width of the cement pole.

[0024] The implementation method of the present invention is as follows: First, the base 1 is firmly placed on the ground to provide a stable support base for the entire rod lifter. The support rod 2 is vertically and firmly fixed on the base 1 to support and connect other components.

[0025] A first ear ring 5 is welded to the side of the upper end of the support rod 2, providing a connection point for the compression rod 4. The compression rod 4 is located at the upper end of the support rod 2, and a second ear ring 6 is welded to the lower front end of the compression rod 4. This second ear ring 6 is sleeved onto the first ear ring 5. This sleeved connection allows the compression rod 4 to move within a certain range relative to the support rod 2 while maintaining a certain degree of stability.

[0026] The front end of the pressure rod 4 is designed with an opening, and a U-shaped ear 7 is welded to the opening. Through holes are respectively provided at both ends of the U-shaped ear 7, and these through holes provide necessary connection points for fixing the insertion rod 3.

[0027] The rod 3 is an integrated design, comprising a rotating portion 8 and a U-shaped rod 9. The rotating portion 8 has a rotation hole that mates with the through-hole in the U-shaped ear 7. Bolts 10 and nuts 11 secure the rod 3 to the U-shaped ear 7. This design allows the rod 3 to be adjusted relative to the compression rod 4 to accommodate cement poles of varying sizes and shapes.

[0028] The U-shaped insertion rod 9 is the main working part of the insertion rod 3. It is used to be inserted into the cement pole 12 and help lift or move the cement pole from the ground or a fixed position by applying pressure or lever action.

[0029] In addition, the design of the insertion rod 3 is replaceable, that is, according to the actual width of the cement pole 12, different sizes of insertion rods 3 can be selected for replacement to ensure that the rod lifter can be applied to cement poles of various sizes, thereby improving the versatility and practicality of the rod lifter.
