Description

Technical Field

[0001] The invention relates to the technical field of rock crushing, and in particular to a hydraulic crushing machine and a working method thereof. Background Art

[0002] In various operations such as mining, tunneling, and roadway construction, we often face a whole surface of rock. Since we have to hollow out the inside of the mountain, and there is no free surface relative to the crushing direction, it causes great difficulties for construction. Common construction methods include explosives and hammer rock drilling. Among them, the explosive blasting method has many limitations and cannot be used in many construction environments. The hammer rock drilling method has the disadvantages of low efficiency, high noise, and high dust, especially when encountering hard rocks.

[0003] Therefore, a process of milling and drilling first and then squeezing and breaking can be adopted to achieve rock fracture and crushing to overcome the above problems. However, there is currently a lack of squeezing and breaking equipment that is inconvenient to operate, stable in operation, and highly efficient. Summary of the invention

[0004] The object of the present invention is to provide a hydraulic crushing machine and a working method thereof, which solves the problems of inconvenient operation, poor running stability and low efficiency of existing crushing equipment.

[0007] A further improvement is that a two-dimensional rotating mounting part is provided on the front end of the machine body and the extrusion assembly, the bottom end of the boom and the bottom end of the swing arm cylinder are connected to the machine body through the two-dimensional rotating mounting part, and the output end of the posture adjustment cylinder and the front end of the boom are connected to the extrusion assembly through the two-dimensional rotating mounting part.

[0008] A further improvement is that the swing arm oil cylinder and the posture adjustment oil cylinder are both double-cylinder structures, and the double cylinders are not in the same vertical plane.

[0009] A further improvement is that the squeezing assembly consists of a frame and a plurality of longitudinal cylinders, a movable seat, a transverse cylinder and a squeezing head.

[0010] A further improvement is that there are three longitudinal oil cylinders, three movable seats, three transverse oil cylinders and three squeezing heads.

[0011] The present invention also provides a working method of the hydraulic crushing machine, the steps comprising:

[0012] The boom can be swung up and down by extending or shortening the two cylinders of the swing arm oil cylinder at the same time, and the boom can be rotated left and right by extending one cylinder of the swing arm oil cylinder and shortening the other cylinder; the up and down inclination angle of the crushing assembly can be changed by extending or shortening the two cylinders of the posture adjustment oil cylinder at the same time, and the left and right inclination angle of the crushing assembly can be changed by extending one cylinder of the posture adjustment oil cylinder and shortening the other cylinder;

DETAILED DESCRIPTION

[0019] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] Combination Figures 1 to 3 As shown, a hydraulic crushing machine includes a body 1, a boom 2, a swing arm cylinder 3, a crushing assembly 4 and a posture adjustment cylinder 5. The boom 2 is rotatably connected to the front end of the body 1, the bottom end of the swing arm cylinder 3 is rotatably connected to the body 1, the output end of the swing arm cylinder 3 is rotatably connected to the boom 2, the crushing assembly 4 is rotatably connected to the front end of the boom 2, the bottom end of the posture adjustment cylinder 5 is rotatably connected to the boom 2, and the output end of the posture adjustment cylinder 5 is rotatably connected to the crushing assembly 4.

[0021] In the present invention, a two-dimensional rotating mounting member 6 is provided on the front end of the machine body 1 and the crushing assembly 4, the bottom end of the boom 2 and the bottom end of the swing arm oil cylinder 3 are connected to the machine body 1 through the two-dimensional rotating mounting member 6, and the output end of the posture adjustment oil cylinder 5 and the front end of the boom 2 are connected to the crushing assembly 4 through the two-dimensional rotating mounting member 6. The two-dimensional rotating mounting member 6 adopts a combined structure of double movable shafts, one of which is arranged horizontally and the other is arranged longitudinally, so as to realize the two-dimensional rotation of the boom 2 and the crushing assembly 4.

[0022] In the present invention, both the swing arm oil cylinder 3 and the posture adjustment oil cylinder 5 are double cylinder structures, and the double cylinders are not in the same vertical plane, for example, they can be designed with one left and one right at the same height. Taking the swing arm oil cylinder 3 as an example, if the two oil cylinders in the double cylinder structure extend at the same time, the big arm 2 can be driven to swing upward, and if the two oil cylinders are shortened at the same time, the big arm 2 can be driven to swing downward, and if one oil cylinder is extended and the other oil cylinder is shortened, the big arm 2 can be driven to rotate toward the shortened oil cylinder. In this way, the double cylinder structure can realize up and down swinging and horizontal rotation, killing two birds with one stone.

[0023] In the present invention, the squeezing component 4 is composed of a frame 401 and a plurality of longitudinal cylinders 402, a movable seat 403, a transverse cylinder 404 and a squeezing head 405. The frame 401 is connected to the upper arm 2 and the posture adjustment cylinder 5. A longitudinal slide rail 406 is formed on the frame 401. The longitudinal cylinder 402 is installed inside the frame 401. The movable seat 403 is movably installed on the longitudinal slide rail 406, and the movable seat 403 is connected to the output end of the longitudinal cylinder 402 in a one-to-one correspondence. The transverse cylinders 404 are installed on the movable seat 403 in a one-to-one correspondence. A transverse slide rail 407 is formed on the movable seat 403. The squeezing heads 405 are movably installed on the transverse slide rail 407 in a one-to-one correspondence, and the squeezing heads 405 are connected to the output end of the transverse cylinder 404 in a one-to-one correspondence.

[0024] When the squeezing assembly 4 is working, the telescopic drive of the longitudinal oil cylinder 402 can drive the moving seat 403 to move along the longitudinal slide rail 406, and then drive the specific squeezing head 405 to move, so as to adjust the spacing between the squeezing heads 405, so that the squeezing assembly 4 can be inserted into the drilled holes with different spacings, and each transverse oil cylinder 404 drives the squeezing head 405 to move along the transverse slide rail 407 through telescopic drive, so that the transverse position of each squeezing head 405 is changed. When encountering a non-linear continuous hole, the transverse position of one or two squeezing heads 405 is changed, so that each squeezing head 405 can be smoothly inserted into the hole and complete the hydraulic squeezing. The squeezing head 405 adopts a conventional structure.

[0025] In the present invention, there are three longitudinal oil cylinders 402, three movable seats 403, three transverse oil cylinders 404 and three squeezing heads 405.

[0026] In the present invention, a motor-driven crawler wheel 7 is provided at the bottom of the machine body 1, and a hydraulic system 8 for providing a hydraulic power source is provided on the machine body 1, and the system includes a hydraulic pump, a valve, a hydraulic oil tank, etc. The swing arm cylinder 3 is located below the boom 2, and the posture adjustment cylinder 5 is located above the boom 2.

[0027] The present invention also provides a working method of a hydraulic squeezer, the steps comprising:

[0028] The boom 2 swings up and down by extending or shortening the two cylinders of the swing arm oil cylinder 3 at the same time, and the boom 2 rotates left and right by extending one cylinder of the swing arm oil cylinder 3 and shortening the other cylinder; the up and down inclination angle of the squeezing assembly 4 changes by extending or shortening the two cylinders of the posture adjustment oil cylinder 5 at the same time, and the left and right inclination angle of the squeezing assembly 4 changes by extending one cylinder of the posture adjustment oil cylinder 5 and shortening the other cylinder;

[0029] Then, through the telescopic drive of the longitudinal cylinder 402, the moving seat 403 is driven to move along the longitudinal slide rail 406, and then the squeezing heads 405 are driven to move to adjust the distance between the squeezing heads 405. Through the telescopic drive of the transverse cylinder 404, the squeezing heads 405 are driven to move along the transverse slide rail 407, so that the transverse position of each squeezing head 405 is changed, and finally each squeezing head 405 is just inserted into the hole to be squeezed, and the hydraulic squeezing work is completed.

[0030] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
