Description

Technical Field

[0001] The utility model relates to the field of scrapers, in particular to an underground scraper. Background Art

[0004] From the above content, it can be seen that when the power mechanism is working, the air blown out by the air intake piece blows out the heat generated by the power mechanism from the air permeable part. While the power mechanism can enter dry gas, it can also ensure the heat dissipation effect of the power mechanism, thereby extending the service life of the body. However, this case still has many shortcomings: when shoveling underground soil, the existing shovel loader collects a certain amount of soil through the bucket and transports it with the bucket. Due to the limited space in the bucket, the transported soil is less, and multiple shoveling is often required. Utility Model Content

[0005] The main technical problem to be solved by the utility model is to provide an underground shovel loader which has a simple structure and is easy to operate, and can especially solve the problem of limited bucket space and less soil to be transported, thereby improving the efficiency of the shovel loader.

[0008] The following is a further optimization of the above technical solution by the utility model:

[0009] The connection assembly comprises two connection frames which are symmetrically fixedly mounted on the fuselage, a connection piece is hinged between the two connection frames, and the other end of the connection piece is hinged to the fixing frame.

[0010] Further optimization: the bucket assembly includes two second hydraulic cylinders symmetrically arranged on both sides of the collecting bucket, and one end of the second hydraulic cylinders is fixedly connected to the fixing frame.

[0011] Further optimization: a second plunger is movably mounted on the output end of the second hydraulic cylinder, and a linkage arm is hinged on the other end of the second plunger.

[0012] Further optimization: the linkage arms are hinged to the fixed frame through pins, and a bucket is fixedly installed between the two linkage arms.

[0015] Further optimization: a rack is fixedly installed on the top of the fuselage, and two searchlights are fixedly installed on one side of the rack.

[0016] The utility model realizes efficient soil collection by setting up the shoveling and collecting device, thereby effectively solving the problem of less soil to be transported due to limited bucket space, and improving the efficiency of shoveling work.

DETAILED DESCRIPTION

[0026] See also Figure 1-Figure 5 As shown, an underground scraper loader includes a body 1, one side of the body 1 is movably connected to a scraper collection device 2 through a connecting assembly 3, a bucket assembly 4 is provided on the scraper collection device 2 away from the body 1, the scraper collection device 2 includes a fixed frame 21, a collection bucket 24 is hinged on the top of the fixed frame 21, a first hydraulic cylinder 22 is hinged on one side of the fixed frame 21, a first plunger 23 is movably installed on the output end of the first hydraulic cylinder 22, and the other side of the first plunger 23 is fixedly connected to the collection bucket 24.

[0027] With this design, firstly, through the articulation of the collecting bucket 24 and the fixed frame 21 and the cooperation of the first hydraulic cylinder 22 and the first plunger 23, the movement of the collecting bucket 24 can be accurately controlled to achieve efficient soil collection, thereby effectively solving the problem of less soil being transported due to limited space in the bucket 44 and improving the efficiency of the shoveling work. Secondly, the body 1 and the shoveling and collecting device 2 are movably connected through the connecting component 3, so that the shovel loader can flexibly adjust the angle and position according to actual needs during operation to adapt to different working environments; thirdly, a stable structural support is provided through the fixed frame 21 to ensure that the shoveling and collecting device 2 remains stable during operation and reduce the risk of shaking and failure.

[0028] The machine body 1 comprises a body 11 , and a crawler track 14 is fixedly mounted on the bottom of the body 11 .

[0029] With such a design, through the installation of the crawler 14, the center of gravity is low and the adhesion coefficient is large during use, and the vehicle has good stability on slopes against overturning and sliding. At the same time, the vehicle also has the characteristics of maneuverability with a small turning radius and strong off-road climbing ability.

[0030] A frame 12 is fixedly mounted on the top of the fuselage 11 , and two searchlights 13 are fixedly mounted on one side of the frame 12 .

[0031] With this design, the two searchlights 13 can provide a brighter and wider lighting range, which helps to improve visibility in specific environments or scenes and facilitates operation or observation.

[0032] The connection assembly 3 includes two connection frames 31 symmetrically fixedly mounted on the fuselage 11 , a connection piece 32 is hinged between the two connection frames 31 , and the other end of the connection piece 32 is hinged to the fixing frame 21 .

[0033] With such a design, firstly, the firmness and balance of the connection with the machine body 1 are ensured through the symmetrical connecting frame 31 , so that the shoveling and collecting device 2 can be stably installed on one side of the machine body 1 .

[0034] Secondly, by means of articulation, the connecting member 32 can be flexibly rotated, so that not only the shoveling and collecting device 2 can be swung and adjusted at multiple angles relative to the body 1 to better adapt to different work scenes and operation requirements; but also the operator can more conveniently change the position and posture of the shoveling and collecting device 2 when operating the shovel loader, thereby improving the convenience and controllability of the operation; at the same time, the articulated structure is relatively simple, which is more convenient when maintenance or replacement of the connecting component 3 is required, thereby reducing the difficulty and cost of maintenance.

[0035] The bucket assembly 4 includes two second hydraulic cylinders 41 symmetrically arranged on both sides of the collecting bucket 24 , and one end of each of the second hydraulic cylinders 41 is fixedly connected to the fixing frame 21 .

[0036] A second plunger 42 is movably mounted at the output end of each of the second hydraulic cylinders 41 , and a linkage arm 43 is hingedly connected to the other end of each of the second plungers 42 .

[0037] With this design, through two symmetrically arranged second hydraulic cylinders 41, it is not only possible to more accurately and flexibly control the movement of the linkage arm 43, thereby achieving fine control of the bucket assembly 4; it is also possible to quickly adjust the position and posture of the bucket 44 according to actual conditions, to adapt to different work requirements, reduce work time, and improve work efficiency; at the same time, the symmetrical arrangement helps to maintain the balance of the bucket assembly 4 during work, reduce shaking and unstable factors, and ensure work safety and quality.

[0038] The linkage arms 43 are hinged to the fixing frame 21 through a pin shaft, and a bucket 44 is fixedly installed between the two linkage arms 43 .

[0039] With this design, firstly, the linkage arm 43 is firmly connected to the fixed frame 21 through the pin hinge, which can better withstand the various forces acting on the bucket 44 when working; secondly, it is convenient for the linkage arm 43 to drive the bucket 44 to perform flexible swinging, lifting and other actions to adapt to different work requirements; thirdly, the two linkage arms 43 work together to make the bucket 44 bear the force more evenly, reduce local stress concentration, and extend the service life of the device.

[0040] A moving wheel 5 is movably mounted on the bottom of the fixing frame 21 .

[0041] This design allows the entire device to be easily moved and to operate flexibly in different locations, thereby improving convenience and efficiency of use.

[0042] Working principle: First, the whole machine is moved by driving the crawler 14; during operation, the bucket 44 in the bucket assembly 4 shovels the soil underground. When the bucket shovels a certain amount of soil, it drives the second hydraulic cylinder 41, and the second hydraulic cylinder 41 pushes the linkage arm 43 through the second plunger 42, thereby driving the bucket 44 to move to a certain angle and dump the soil into the collection bucket 24.

[0043] When the collecting bucket 24 is full of soil, the soil collected in the collecting bucket 24 is transported. When it reaches a designated point, the first hydraulic cylinder 22 is driven to extend and retract the first plunger 23, thereby driving the collecting bucket 24 to flip around the hinge between the collecting bucket 24 and the fixing frame 21, and pouring out the soil collected inside.

[0044] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
