Detailed Description

The following describes the specific structure of the present invention in detail with reference to the accompanying drawings.

As shown in fig. 1, 2 and 3, a generator 1 is used for providing power supply, the output voltage is 380V, an alternating current motor 2 is used as power output, a worm gear speed reducer 3 and a chain transmission device, including a small chain wheel 4, a chain 5 and a large chain wheel 6, are used for speed reduction transmission, the worm gear speed reducer 3 is fixed on a forklift support 7, the large chain wheel 6 is installed on a crank 9, the crank 9 is connected with symmetrical cranks 24 through a cross rod 23 to form an output end, the symmetrical cranks 24 are installed on a bearing seat 8, and the bearing seat 8 is fixed on the forklift support 7. One end of the connecting rod 10 is connected with the middle section of the crank 9, and the other end is connected with the middle section of the scraper knife push rod 11. Two ends of a scraper knife push rod 11 are respectively inserted into the central holes of a push rod sliding block 12, the push rod sliding block 12 is arranged inside a guide rail 13, and the guide rail 13 is fixed at the front end of the forklift support 7. A plurality of movable shovel rod 14 are simultaneously arranged in the middle of the shovel blade push rod 11, and the tail end of the shovel rod 14 is fixedly connected with a shovel blade 15.

In addition, a pressure bar sliding block 16 is arranged in the guide rail 13 and is away from the front end of the push rod sliding block 12, and the pressure bar sliding block 16 is connected with the push rod sliding block 12 through a sliding block connecting rod 17. The two ends of the compression bar 18 are inserted into the compression bar sliding blocks 16 on the two sides, the middle part of the compression bar 18 is sleeved with the movable compression spring mounting seat 20, meanwhile, the part of the shovel bar 14 close to the shovel blade 15 is also sleeved with the movable compression spring mounting seat 20 and is aligned with the compression spring on the compression bar, and the compression spring 19 is arranged between the two compression spring mounting seats 20. The bottom of the forklift frame is provided with a directional caster 21 and a movable caster 22 respectively.

During operation, the land shoveling vehicle is placed in the area where the waterproof layer is to be shoveled, the waterproof layer is slightly peeled off by using a tool, and then the land shoveling vehicle is pushed, so that the cutting edge of the shovel blade 15 enters between the waterproof layer and the roadbed. The generator 1 is started, a power switch of the alternating current motor 2 is connected, the motor outputs the rotating speed of 1400r/min, the rotating speed is transmitted by a worm gear reducer 3 with the reduction ratio of 50 and chain wheels with the transmission ratio of 2, 4, 5 and 6, the crankshaft 7 rotates at the rotating speed of 14r/min, and the scraper knife push rod 11 and the push rod slide block 12 are driven to do reciprocating linear motion through the connecting rod 10. The press rod sliding blocks 16 and the push rod sliding blocks 12 move synchronously, so that the press rod 18 and the scraper knife push rod 11 also move synchronously, and the compression spring 19 between the compression spring mounting seats 20 on the upper surface can keep pressure on the scraper knife rod 14 all the time, so that the scraper knife 15 fixedly connected with the scraper knife rod 14 is in contact with the surface of the roadbed all the time to adapt to slight change of the gradient of the surface of the roadbed. The scraper knife reciprocates 1 time to remove the waterproof layer in the stroke, and an operator can push the ground shoveling vehicle to move forward according to the linear speed obtained by the conversion of the crank rotating speed and the specific stroke, so that the waterproof layer is continuously stripped and removed, and the removed waterproof layer is collected by other personnel at the back. The working speed of the product design is 4.2m/min, so that the waterproof layer with the length of 1km can be removed after four hours of work every day, and the working efficiency of the product is greatly higher than that of the manual removal progress by 100 m/day.
