Description

Technical Field

[0001] This utility model relates to the field of leveling device technology, specifically a ground leveling device suitable for use. Background Technology

[0002] As is well known, in land leveling operations, traction equipment such as tractors is often used to assist in operation in order to improve work efficiency. Usually, a special mounting frame is installed at the rear of the tractor, and a scraper is equipped on the mounting frame and fixed rod. The scraper is pulled by the tractor or other traction equipment to achieve the leveling of the ground.

[0003] The existing scraper has certain defects in its installation structure. Currently, scrapers typically have a fixing rod at the rear, which is welded to the scraper. During actual land leveling, the scraper inevitably comes into contact with hard objects such as gravel, bricks, and metal blocks on the ground. Collisions with these objects can easily damage the scraper. Because the fixing rod is welded to the scraper, when the scraper is damaged and needs repair, it cannot be replaced individually; the entire scraper assembly must be removed from the mounting frame for repair or replacement. This repair method is not only cumbersome, increasing repair time and labor costs, but also affects the progress of land leveling operations and reduces work efficiency. Therefore, it is necessary to improve the existing scraper structure to solve the above-mentioned problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the prior art, the present invention provides a suitable ground leveling device, which solves the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a ground leveling device, comprising a mounting frame and a push plate mounted on a traction device, a T-shaped connecting block on the back of the push plate, a connecting structure on the mounting frame, a fixing rod at the bottom of the connecting structure, a groove on the front side wall of the fixing rod, a threaded assembly rotatably connected to the fixing rod through the groove, two corresponding sliders threadedly connected to the threaded assembly in the groove, rotating the threaded assembly causing the sliders to move towards or away from each other on the groove, slots on the sliders matching the connecting block, rotating the threaded assembly causing the two sliders to move towards each other, the connecting block entering the slots of the two sliders, and the push plate being mounted on the fixing rod.

[0008] Furthermore, the threaded assembly includes a first threaded rod, which has threads in opposite directions starting from the middle and extending to both ends. Two sliders are placed on different threads of the first threaded rod to form a threaded connection. A rotating block that is rotatably connected to a fixed rod is provided near the end of the first threaded rod. The rotating block plays a role in limiting the first threaded rod on the fixed rod. A rotating handle is provided at the bottom of the first threaded rod.

[0009] Furthermore, the connecting structure includes a connecting plate, the top of which is provided with a second threaded rod that penetrates the mounting bracket, and a nut is threaded onto the second threaded rod for mounting a fixing rod on the mounting bracket. The connecting plate has multiple first insertion holes in a ring shape, and the mounting bracket has second insertion holes, through which pins penetrating the first insertion holes are inserted.

[0010] Furthermore, U-shaped guide plates are provided on both sides of the fixing rod, and the guide plates and the fixing rod form a through hole. Two guide rods are provided on the back of the push plate, and the guide rods pass through the through hole.

[0011] (III) Beneficial Effects

[0012] Compared with the prior art, the present invention provides a suitable ground leveling device, which has the following beneficial effects:

[0013] In existing devices, the scraper is welded to the fixing rod, making it impossible to replace the scraper individually when damaged; the entire device must be disassembled for repair. This new device, however, features a unique threaded assembly on the fixing rod, including a first threaded rod, a rotating block, and a rotating handle. By rotating the handle, the first threaded rod easily drives the slider to slide within a groove, enabling quick connection and separation of the push plate and the fixing rod. When replacing the push plate, simply rotate the handle to slide the slider backwards, allowing the push plate's connecting block to detach from the slider. The old push plate can then be removed, and the new push plate inserted and the handle rotated in the opposite direction to secure it. This significantly improves replacement efficiency and reduces maintenance time and labor costs. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 The present invention relates to a ground leveling device, comprising a mounting frame 1 and a push plate 2. The mounting frame 1 is installed on a traction device, which is existing technology and will not be described in detail here.

[0020] The mounting bracket 1 has a third insertion hole with a connecting structure. This connecting structure includes a connecting plate 11, which is positioned at the bottom of the mounting bracket 1. A second threaded rod 12 is located at the top of the connecting plate 11, passing through the third insertion hole of the mounting bracket 1. A nut 13 is threaded onto the second threaded rod 12, fixing both the second threaded rod 12 and the connecting plate 11 to the mounting bracket 1. The connecting plate 11 has multiple first insertion holes 14 arranged in a ring. The mounting bracket 1 has second insertion holes, through which pins 15 are inserted, passing through the first insertion holes 14. The pins 15 limit and fix the mounting bracket 1 and the connecting plate 11.

[0021] The bottom of the second threaded rod 12 is connected to a fixed rod 3. The front side wall of the fixed rod 3 has a sliding groove 4. Both ends of the sliding groove 4 have rotating grooves that communicate with it. A threaded assembly 6 is installed on the fixed rod 3. The threaded assembly 6 includes a first threaded rod 8. The first threaded rod 8 passes through the sliding groove 4. A rotating block 9 is placed in the rotating groove near the end of the first threaded rod 8. The rotating block 9 plays a role in limiting the first threaded rod 8 on the fixed rod 3. The first threaded rod 8 passes downward through the bottom of the fixed rod 3, and a rotating handle 10 is installed at the end of the threaded rod. By rotating the rotating handle 10, the first threaded rod 8 can rotate on the fixed rod 3.

[0022] Two sliders 5 are provided in the slide groove 4. Each slider 5 has a threaded hole. The first threaded rod 8 has threads in opposite directions starting from the middle and extending to both ends. The two sliders 5 are placed on different threads of the first threaded rod 8 to form a threaded connection. When the first threaded rod 8 rotates, it drives the two sliders 5 to move towards or away from each other on the slide groove 4.

[0023] The push plate 2 has a T-shaped connecting block 7 on its back. The slider 5 has a slot that matches the connecting block 7. Rotating the handle 10 causes the two sliders 5 to move towards each other, and the connecting block 7 enters the slot of the two sliders 5, thus installing the push plate 2 on the fixing rod 3.

[0024] Rotate the push plate 2 to make the second threaded rod 12 rotate in the third insertion hole of the mounting bracket 1, adjust the tilt angle of the push plate 2, and then insert the pin 15 into the second insertion hole, and the pin 15 passes through the first insertion hole 14 of the connecting plate 11 to fix the push plate 2.

[0025] The fixed rod 3 has U-shaped guide plates 16 welded on both sides. The guide plates 16 and the fixed rod 3 form through holes. The back of the push plate 2 is connected to two guide rods 17, which pass through the through holes and are installed on the push plate 2 on the fixed rod 3 to provide guidance.

[0026] In summary, when the push plate 2 is replaced on the fixed rod 3, the rotating handle 10 is rotated, which drives the first threaded rod 8 to drive the two sliders 5 to slide in opposite directions in the slide groove 4, so that the T-shaped connecting block 7 is disengaged from the slider 5. The push plate 2 is held to remove the connecting block 7 from the slide groove 4, and at the same time the guide rod 17 is removed from the guide plate 16.

[0027] Holding the new push plate 2, align the guide rod 17 with the through hole formed by the guide plate 16 and the fixed rod 3, and insert it so that the push plate 2 is supported on the fixed rod 3. Continue to push the push plate 2 so that the connecting block 7 connected to the push plate 2 enters the interior of the fixed rod 3 along the slide groove 4. Rotate the handle 10 in the opposite direction to drive the first threaded rod 8 to rotate on the fixed rod 3. At the same time, drive the two sliders 5 to move towards each other so that the connecting block 7 enters the slot of the slider 5 and is fixed, thereby completing the replacement of the push plate 2.

[0028] This device allows for convenient and efficient replacement of the push plate 2, improving replacement efficiency.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
