Technical Field

[0001] The utility model relates to the technical field of land leveling in the agricultural and construction industries, and particularly relates to a land leveling scraper. Background Art

[0002] At present, most of the rural population in China chooses to enter cities for development, and a large amount of land is uncultivated. In the future, with the decrease in the birth rate, it can be predicted that the number of people engaged in agricultural production will be less and less. The traditional agricultural production is characterized by high labor intensity and long working hours, which makes many young people reluctant to engage in agricultural production, resulting in agricultural discontinuity in many areas. Therefore, in order to promote the modern development of agricultural production, it is necessary to introduce a mechanized production method to reduce the labor intensity of agricultural producers and make the input and output of producers proportional. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a land leveling method with high accuracy and low operation difficulty to improve the land leveling efficiency.

[0004] To solve the above technical problem, a land leveling scraper provided by the utility model includes a bucket, a bulldozer blade, a lifting frame, wheels, a lifting oil cylinder, a bulldozer blade oil cylinder and a fuel tank. A V-shaped connecting rod for connecting a trailer is arranged at the front end of the bucket. The wheels are installed at the rear end of the lifting frame. The front end of the lifting frame is hinged to the bottom of the rear end of the bucket. Two ends of the lifting oil cylinder are respectively hinged to the rear end of the lifting frame and the top of the rear end of the bucket. The bulldozer blade is installed in the bucket and is connected with the bulldozer blade oil cylinder arranged at the rear side of the bucket.

[0005] Preferably, the land leveling scraper further includes three ranging sensors, namely a bucket height sensor arranged at the rear end of the lifting frame for detecting the height of the bucket from the ground, a soil layer height sensor arranged inside the top of the bucket for detecting the height of the soil layer in the bucket, and a position sensor arranged inside the rear end of the bucket for detecting the position of the bulldozer blade. A screen, and the three ranging sensors are connected to a controller.

[0006] Preferably, an operating lever for controlling the actions of the lifting oil cylinder and the bulldozer blade oil cylinder is connected to the controller.

[0009] Advantages of the present utility model: The land-leveling scraper of the present utility model can be installed at the rear of a trailer, and the gear pump of the scraper is driven by the transmission shaft at the rear of the trailer to provide hydraulic power. The trailer is manually driven to transport the soil material at a higher elevation to a lower elevation. During the transportation process, the scraper is supported by wheels. The controller controls the telescopic movement of the lifting cylinder through the solenoid valve, thereby adjusting the height of the bucket in real time and maintaining the bucket at the required elevation, and then implementing the land-leveling and scraping operation.

[0017] As Figures 1-6 , a land-leveling scraper in this embodiment includes a bucket 1, a bulldozing plate 2, a lifting frame 3, wheels 4, a lifting cylinder 5, a bulldozing plate cylinder 6, and a fuel tank 7. A V-shaped connecting rod for connecting the trailer is provided at the front end of the bucket 1. The wheels 4 are installed at the rear end of the lifting frame 3. The front end of the lifting frame 3 is hinged to the bottom of the rear end of the bucket 1 through a pair of hinges. Both ends of the lifting cylinder 5 are respectively hinged to the rear end of the lifting frame 3 and the top of the rear end of the bucket 1. The bulldozing plate 2 is installed in the bucket 1, and the bulldozing plate 2 is connected to the bulldozing plate cylinder 6 provided at the rear side of the bucket 1. The fuel tank 7 is installed above the bucket 1. A solenoid valve 8 for controlling the lifting cylinder 5 and the bulldozing plate cylinder 6, and a satellite antenna 9 for communication are provided on the fuel tank 7. The fuel tank 7 is connected to the gear pump 11 through an oil pipe 10.

[0018] Three ranging sensors 12 are provided on the scraper. The three ranging sensors are respectively a bucket height sensor 12-1 provided at the rear end of the lifting frame 3 for detecting the height of the bucket from the ground, a soil layer height sensor 12-2 provided inside the top of the bucket 1 for detecting the height of the soil layer in the bucket, and a position sensor 12-3 provided inside the rear end of the bucket 1 for detecting the position of the bulldozing plate. The screen, the three ranging sensors 12, the solenoid valve 8, and the satellite antenna 9 are connected to the controller. The controller is preferably a single-chip microcomputer or a PLC.

[0019] Preferably, the ranging sensor 12 can be a laser or ultrasonic sensor.

[0020] The manual driving trailer transports the soil materials at the high terrain to the low terrain. During the transportation process, the scraper is supported by the wheels 4. The controller controls the telescoping of the lifting oil cylinder 5 through the solenoid valve 8, thereby adjusting the height of the bucket 1 in real time and maintaining the bucket at the required elevation.

[0021] The scraper is provided at the tail of the trailer, and the gear pump driven by the transmission shaft at the tail of the trailer provides hydraulic power for the scraper. The trailer is preferably a tractor.

[0022] During the scraping operation, a certain amount of soil materials will be reserved in the bucket. The bucket height sensor 12-1 behind the scraper measures the height of the ground from the bucket in real time. If there is a certain distance between the bottom of the bucket and the ground, the distance information will be displayed on the screen connected to the controller; at this time, the operator manually controls the bulldozing plate 2 to move forward to push the soil in the bucket out to fill the gap between the ground and the bucket; if there is no gap between the bottom of the bucket and the ground, the bucket height sensor 12-2 installed above the bucket will detect the height of the soil layer in the bucket and display the height information on the screen; when it is higher than a certain amount, the operator manually controls the bulldozing plate to move backward to create space for loading more soil materials. The position sensor 12-3 behind the bulldozing plate will monitor the position of the bulldozing plate in real time to monitor and control the amount of soil loaded in the bucket. The above adjustment process of the scraper can be achieved through manual operation. The user drives the trailer and pays attention to the screen information to perform the operation. Embodiment 2

[0023] On the basis of the above Embodiment 1, the above scraping operation process can also be automatically completed by the controller.

[0024] The controller determines the absolute height of the bucket through the satellite antenna, and controls the lifting oil cylinder to lift and lower by controlling the solenoid valve to maintain the bucket at a fixed height. The difference between the height of the bucket from the ground measured by the ranging sensor and the absolute height of the bucket is used as a control parameter to automatically control the bucket to complete the soil loading or unloading operation, thereby realizing automatic land leveling.

[0025] The user can turn on or off the automatic land leveling function through the controller screen installed in the cab. After turning on the automatic land leveling, the user only needs to focus on driving the tractor. This new model will control the activities of key components according to satellite signals and ranging sensor signals, automatically complete the operations of loading and unloading soil, and achieve automatic land leveling.

[0026] The above is the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle described in the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
