Description

TECHNICAL FIELD

[0001] The utility model relates to a scraper, more specifically, relates to a scraper suitable for agricultural road, field, dam, earthwork engineering and irrigation channel ground leveling. BACKGROUND

[0002] In the process of agricultural production and engineering construction, the ground is often leveled, such as leveling of farmland, agricultural road, and leveling of dam and earthwork engineering. During the ground leveling process, the protruding soil or material needs to be transferred to the low-lying part for filling to finally achieve the leveling of the ground. The existing ground leveling work usually uses manual or bulldozer to realize. In the case of small engineering quantity, manual excavation of the protruding part is adopted, and then the protruding part is transported to the low-lying part for filling. In the case of large engineering quantity, the bulldozer is used to push the ground to be flat.

[0003] However, manual ground leveling has the disadvantages of high labor intensity, low work efficiency and high cost, and is not suitable for large-scale engineering construction. The bulldozer can only be used for construction in a relatively wide space, and cannot be used for leveling of agricultural road, dam and irrigation channel with relatively small space. Moreover, the bulldozer cannot be used for leveling of the field, otherwise it will cause compaction and hardening of the field, which is not conducive to the planting of crops. Therefore, the utility model provides a ground leveling scraper with wide application range and good ground leveling effect. SUMMARY

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1 to 6 As shown, the front view, rear view, top view, bottom view, left view, and right view of the ground leveling scraper of this utility model are given respectively. Figure 7 , Figure 8 and Figure 9 All of them are given a 3D diagram. Figure 10 An exploded view of its structure is given. Figure 8 and Figure 9 The 3D diagram shows a soil scraper truck for ground leveling, with some structures removed. The truck consists of a frame 1, a cargo box 2, and wheels 3. The frame 1 provides fixation and support, the wheels 3 are located on both sides of the frame 1, and the cargo box 2 is mounted on the frame 1. The wheels 3 support the frame 1 and cargo box 2, allowing the scraper truck to move under the action of traction machinery. A traction head 5 is fixed to the front end of the frame 1, connecting to the traction machinery. Horizontally facing outward-facing axles 14 are fixed to both sides of the rear of the frame 1. The wheels 3 rotate on the axles 14, enabling the scraper truck to move freely.

[0024] Both sides of the rear of the frame 1 are fixed with pivot seats 13, and both sides of the rear of the carriage 2 are fixed with horizontally outward pivots 26. The pivots 26 are inserted into the pivot seats 13, allowing the carriage 2 to rotate around the pivots 26. The interior of the carriage 2 is a storage chamber 6, where soil or materials cut from the ground protrusions are temporarily stored. Both sides of the front of the carriage 2 are equipped with hydraulic cylinders 4, which are tilted backward and upward. The front end of the hydraulic cylinder 4 is hinged to the front end of the frame 1 via a lower pin 15, and the rear end of the hydraulic cylinder 4 is hinged to the upper end of the middle of the carriage 2 via an upper pin 16. Thus, when the hydraulic cylinder 4 extends, it drives the carriage 2 to rotate backward and upward around the pivots 26, thereby emptying the soil or materials stored in the storage chamber 6.

[0025] The bottom of the front end of the carriage 2 shown has a feed inlet 17, which is connected to the storage chamber 6. The bottom of the feed inlet 17 is a base plate 18, on which a scraper 7 is fixed by pins 25. The scraper 7 is used to cut off protruding soil or materials. A baffle plate 8 is provided on the feed inlet 17 to allow soil or materials to enter the carriage 2, but not to allow materials or soil to flow out of the feed inlet 17. That is, when materials enter the storage chamber 6 from the feed inlet 17, the baffle plate 8 is in the open state, and when no soil or materials enter, the baffle plate 8 seals the feed inlet 17.

[0026] In this way, during use, the scraper truck travels on the ground to be leveled under the action of the traction machinery. In the area where the truck bed 2 passes, soil or materials protruding from the ground are cut off by the scraper blade 7. The cut soil or materials exert a backward force on the baffle plate 8, causing the baffle plate 8 to flip backward, opening the feed inlet 17, and allowing the soil or materials to enter the storage chamber 6. When no soil or materials enter, the baffle plate 8 falls back under its own weight or the pressure of the materials in the storage chamber 6, closing the feed inlet 17. When the truck bed 2 is full of soil or materials, the scraper truck is pulled to a low-lying area on the ground, causing the hydraulic cylinder 4 to extend, causing the truck bed 2 to flip backward, dumping out the soil or materials, thus leveling the low-lying area.

[0027] like Figure 11 The diagram shows the structural schematic of the carriage of this utility model. Above the feed inlet 17 at the front end of the carriage 2 is a top guard plate 19. The retaining plate 8 consists of a limiting support plate 20, a blade shaft 22, and retaining blades 23. The limiting support plate 20 is fixed to the inner wall of the top guard plate 19 by pins. Multiple ear plates 21 are evenly fixed along the length of the limiting support plate 20, and shaft holes are provided on the ear plates. The retaining blades 23 are elongated, and their upper ends are hinged to the blade shaft 22, allowing the retaining blades 23 to rotate on the blade shaft 22. The blade shaft 22 passes through the shaft holes of the ear plates 21 on the limiting support plate 20.

[0028] Thus, when the retaining blade 23 is not subjected to external force, it droops under its own weight, and the limiting plate 20 limits the retaining blade 23 to prevent it from moving outward excessively. At this time, the feed inlet 17 is in a sealed state. When the soil or material cut by the scraper 7 applies a backward force to the retaining blade 23, the retaining blade 23 flips backward along the blade shaft 22, the feed inlet 17 opens, and the soil or material enters the storage chamber 6. When no soil or material enters, under the weight of the retaining blade 23 or the pressure of the material in the storage chamber 6, the retaining blade 23 rotates downward to the position limited by the limiting plate 20. At this time, the feed inlet 17 is in a closed state, and the material in the storage chamber 6 cannot flow out through the feed inlet 17.

[0029] The carriage 2 shown has a forward-sloping, upward-inclined support rod 10. A rotating shaft 26 is fixed to the support rod 10, and the upper end of the hydraulic cylinder 4 is hinged to the upper end of the support rod 10 via an upper pin 16. Both sides of the frame 1 shown have longitudinal beams 12, and axle seats 13 are mounted on the longitudinal beams 12. A horizontally outward-facing wheel axle 14 is fixed to the longitudinal beam 12, and the wheels rotate on the wheel axles 14.

[0030] The rear end of the shown carriage 2 is provided with a rear baffle 9, the cross section of the rear baffle 9 is circular arc shape with the rotation shaft 26 as the circle, since the rear baffle 9 adopts the circular arc shape, the soil or material can be effectively avoided to be stuck in the rear end inside the carriage 2, and the material can be completely poured out.
