Description

Technical Field

[0001] This utility model belongs to the field of engineering machinery technology, and in particular relates to a folding drill arm. Background Technology

[0002] Construction machinery is a general term for construction machinery used in engineering construction. There are many types of machinery. Using machinery can quickly speed up the construction progress and reduce the labor intensity of workers. In mining or drilling, drilling machinery is often needed. Drilling machinery can reduce the danger of mining methods and improve the accuracy of drilling.

[0003] However, the most commonly used drilling machines currently employ straight-arm drilling arms, which are hinged and fixed to the boom base. Two hydraulic cylinders support the swing angle: a lifting cylinder for raising and lowering the drilling arm, and a swing angle cylinder for swinging the drilling arm left and right. Because the drilling arm is hinged and fixed to the boom base, it cannot be retracted, resulting in an excessively long drilling machine. This requires more space when using the machine, and the long drilling arm also hinders the transportation of the machine, increasing transportation costs to some extent.

[0004] Meanwhile, the drill rod of the drilling rig generates a lot of heat during high-intensity, long-term operation, which leads to a reduction in the service life of the drill bit. Utility Model Content

[0005] The purpose of this invention is to provide a folding drill arm to solve the technical problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of this utility model, and these aspects can be achieved even without these specific details.

[0025] A type of folding drill arm, such as Figures 1-5 As shown, a folding drill arm includes a main arm 1 and a rear drill arm 2. The end of the main arm 1 is rotatably connected to a hinge seat A 3. The rear drill arm 2 is hinged to the inner wall of the hinge seat A 3. A folding assembly is provided on the outer wall of the hinge seat A 3.

[0026] The folding assembly includes an abutment seat 4 fixedly connected to the inner wall of hinge seat A 3, hinge seat B 5 fixedly connected to the side wall of the main arm 1, hydraulic master cylinder 6 hinged to the side wall of hinge seat B 5, the output end of hydraulic master cylinder 6 hinged to abutment seat 4, a rotating shaft 7 rotatably connected to the end of the rear drilling arm 2, a base 8 rotatably connected to the outer wall of the rotating shaft 7, a lifting seat 9 fixedly connected to the lower bottom end of the base 8, a hydraulic rod 10 hinged to the lower bottom end of hinge seat A 3, and the output end of hydraulic rod 10 rotatably connected to the outer wall of lifting seat 9.

[0027] A support frame 11 is fixedly connected to the outer wall of the main boom 1, and a crushing seat 12 is rotatably connected to the inner wall of the support frame 11. A crushing rod 13 is fixedly connected to the end of the crushing seat 12.

[0028] A rotating shaft 14 is fixedly connected to the inner wall of the crushing seat 12, and a push plate 15 is rotatably connected to the outer wall of the rotating shaft 14. A hydraulic auxiliary cylinder 16 is hinged to the lower end of the B hinge seat 5, and the output end of the hydraulic auxiliary cylinder 16 is hinged to the outer wall of the push plate 15.

[0029] Specifically, the cooperation between the main boom 1 and the rear drilling arm 2 improves the drilling angle adjustment. Multiple angle adjustments facilitate operation within a limited space, increasing drilling efficiency. The A-hinged seat 3 allows for easy opening and closing of the main boom 1 and the rear drilling arm 2. During transport, the drilling arms can be folded to reduce their footprint. The cooperation between the A-hinged seat 3, the B-hinged seat 5, and the hydraulic master cylinder 6 enables hydraulic power to swing the main boom 1, improving drilling accuracy. The rear drilling arm 2, the rotating shaft 7, the base 8, and the lifting seat 9 allow for quick connection between the base 8 and the main body. The lifting seat 9 drives the hydraulic rod 10 to adjust the angle of the A-hinged seat 3. The adjustment allows the main boom 1 to retract inwards. The crushing seat 12 on the inner wall of the support frame 11 can fix the crushing rod 13, facilitating the crushing rod 13 to drill into the target point and ensuring that the crushing rod 13 will not shake due to vibration, thus improving the crushing accuracy of the crushing rod 13. Through the cooperation of the rotating shaft 14, the push plate 15 and the hydraulic auxiliary cylinder 16, the angle of the crushing seat 12 can be adjusted by the contraction of the hydraulic auxiliary cylinder 16, thereby adjusting the angle of the crushing rod 13. The swing of the crushing rod 13 further improves the drilling accuracy. This component has a simple structure and strong practicality. It can improve the angle adjustment of the drill arm by adjusting the position of each cylinder and cooperating with each hinge seat, thereby improving the drilling accuracy and facilitating the transportation of the machinery.

[0030] A cooling box 17 is fixedly connected to the top of the main boom 1. An electric push rod 18 is fixedly connected to the top of the main boom 1 on one side of the cooling box 17. An extrusion plate 19 is fixedly connected to the output end of the electric push rod 18. The extrusion plate 19 slides on the inner wall of the cooling box 17. A water outlet seat 20 is fixedly connected to the side wall of the cooling box 17.

[0031] A cooling pipe 21 is fixedly connected to the outer wall of the water outlet seat 20, and a water rotating seat 22 is fixedly connected to the outer wall of the crushing rod 13. A water spray pipe 23 is fixedly connected to the bottom end of the water rotating seat 22.

[0032] A water storage tank 24 is fixedly connected to the side wall of the crushing seat 12. A water inlet is provided at the top of the water storage tank 24. An atomizing nozzle 25 is fixedly connected to the side wall of the water storage tank 24.

[0033] Specifically, a cooling box 17 is fixedly connected to the top of the main boom 1. Through the cooperation of the cooling box 17, electric push rod 18, extrusion plate 19 and water outlet seat 20, the drill bit will generate high temperature during continuous operation during the crushing process. The heat is slowly dissipated through natural heat dissipation, and the high temperature will also affect the strength of the crushing drill bit. The operator starts the electric push rod 18 to drive the extrusion plate 19 to squeeze into the cooling box 17. Through extrusion, the coolant is forced from the cooling pipe 21 into the water outlet seat 22, and then sprayed onto the drill bit through the water spray pipe 23. The coolant quickly dissipates the heat generated by the drill bit, improves the service life of the drill bit, and reduces the wear of the drill bit. Since dust particles are often generated during drilling, which not only affect the operator's vision but also cause some pollution to the air in the operating environment, the water is atomized and sprayed out using the atomizing nozzle 25 on one side of the water storage tank 24 to reduce dust in the air, improve the air quality of the operating environment, and improve visibility in the confined environment.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
