Description

Technical Field

[0001] This application relates to the field of mechanical equipment, and more specifically, to a trench filling device. Background Technology

[0002] When heavy vehicles drive over soft, soil-like surfaces, their wheels easily create trenches, resulting in uneven ground. This causes the wheels of following vehicles to sink into the trenches, hindering their movement. Current solutions for these trenches typically involve workers manually filling them with tools to facilitate vehicle movement. However, this method is extremely labor-intensive, inefficient, and often results in uneven trenches.

[0003] Therefore, in order to overcome the shortcomings of the existing technology, there is a need to provide a trench filling device. Utility Model Content

[0041] In the following description, numerous specific details are set forth for illustrative purposes and to provide a comprehensive understanding of one or more embodiments. However, it will be apparent that these embodiments can also be implemented without these specific details.

[0042] In the description of this application, it should be noted that the terms "upper," "lower," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Unless otherwise expressly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0043] It should also be noted that, in the description of this application, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0044] To address the problems existing in the prior art, one embodiment of this application provides a trench filling device, such as... Figure 1-3 As shown, the device includes a frame connected to a motor vehicle, which may be a tractor; at least one loosening unit located below and connected to the frame, preferably having two loosening units; each loosening unit includes two oppositely arranged loosening components for loosening the soil on the ground; two oppositely arranged scraper assemblies installed on the side of the frame away from the motor vehicle, each scraper assembly including a scraper; the angle formed between the extending direction of one scraper and the extending direction of the other scraper is 100° to 150°; the two scrapers are configured to collect the loosened soil between the two scrapers.

[0045] In the above embodiments of this application, two loosening components and two scraper components are respectively connected to a frame, which is connected to a motor vehicle. When the motor vehicle moves the frame, the two loosening components and two scraper components can move under the drive of the frame. The design of the angle between the extension direction of one scraper and the extension direction of the other scraper being 100° to 150° creates a collection area between the two scrapers, allowing them to collect the loosened soil. The trench filling device provided by this application can fill trenches formed by motor vehicle wheels on the ground. Specifically, because there is a lot of soil on both sides of the trench, the trench is relatively high. When the motor vehicle moves the entire trench filling device forward, firstly, the loosening components loosen the soil on both sides of the trench. Then, the two scrapers located on the side of the loosening components away from the motor vehicle collect the loosened soil between the two scrapers. Under the push of the scrapers, the soil enters the trench, and the scrapers can also level the soil on the top surface of the trench, making the ground flat.

[0046] The two soil loosening components are a first soil loosening component 3 and a second soil loosening component 4, and the two scrapers are a first scraper 5 and a second scraper 6. The first soil loosening component 3 is arranged opposite to the first scraper 5, and the second soil loosening component 4 is arranged opposite to the second scraper 6. After the first soil loosening component 3 loosens the soil on the ground, the corresponding first scraper 5 scrapes the loosened soil. After the second soil loosening component 4 loosens the soil on the ground, the corresponding second scraper 6 scrapes the loosened soil. In this way, when the two scrapers scrape the soil, the reaction force of the soil on the scrapers is reduced, which helps the scrapers to scrape the soil. Under the action of the two scrapers, the soil can enter the trench and achieve trench filling.

[0047] In one specific example, the soil loosening assembly includes a mounting rod 31 fixed to a frame; two extension rods 32 extending downward from both ends of the mounting rod 31; and a fixing rod 33 passing through and fixedly connected to the two extension rods 32 respectively. Multiple soil loosening discs 34 are arranged sequentially on the fixing rod 33, and the soil loosening discs 34 are rotatably connected to the fixing rod 33. The mounting rod 31, extension rods 32, and fixing rod 33 allow the multiple soil loosening discs 34 to be installed below the frame, thereby loosening the ground soil.

[0048] Specifically, the loosening plate 34 is formed by gradually indenting the edge of one side surface of a circular plate; the loosening plate 34 includes a central through hole, through which the fixing rod 33 passes. The outer circumference of the loosening plate 34 is circular; one side surface of the loosening plate 34 is concave, and the other side surface is convex. The loosening plate 34 formed in this way can enter the interior of the soil on the ground under the movement of the frame. Because the loosening plate 34 has a concave surface, it can turn over the soil during movement, thus loosening the soil. Here, the concave surfaces of the multiple loosening plates 34 on the fixing member are oriented in the same direction.

[0049] In one specific embodiment, the scraper assembly includes two parallel support rods extending outward from the side of the frame away from the vehicle. The two support rods are a first support rod 51 and a second support rod 52. The end of the first support rod 51 near the side of the frame is shorter than the length of the second support rod 52. The scraper is connected to the first support rod 51 and the second support rod 52 via a connecting assembly. The connecting line between the end of the first support rod 51 away from the frame and the end of the second support rod 52 away from the frame is parallel to the scraper. The two support rods allow the scraper to be installed on the side of the frame away from the vehicle, meaning that when the vehicle is moving, the loosening assembly first loosens the soil, and then the scraper scrapes the loosened soil. The design that the length of the first support rod 51 is shorter than the length of the second support rod 52 causes the scraper to be in an inclined state, so that a collection area is formed between the two scrapers.

[0050] In one specific example, the end of the support rod away from the frame includes a connecting block 53, the connecting block 53 including a first connecting surface and a second connecting surface; the connecting assembly includes a first connecting member 54 fixedly connected to the first connecting surface of the connecting block 53; and a rotating rod 55 rotatably connected to the first connecting member 54, the end of the rotating rod 55 away from the connecting block 53 being fixedly connected to the side of the scraper facing away from the vehicle. The use of the first connecting member 54 and the rotating rod 55 connects the scraper to the support rod; since the scraper is subjected to a reverse thrust during the scraping of the soil, the scraper will rotate slightly in the direction away from the connecting block 53, so that the angle between the scraper and the ground is less than 90°, making it easier to fill the trench with soil during the scraping of the soil.

[0051] In one specific example, a second connecting member is fixedly connected to the second connecting surface of the connecting block 53; a limiting component is provided between the second connecting member and the rotating rod 55. The limiting component is configured to limit the rotation angle of the rotating rod 55 when the scraper scrapes the soil and drives the rotating rod 55 to rotate. In practical applications, when the scraper is scraping the soil, the scraper will rotate in the direction away from the connecting block 53. At this time, under the restriction of the limiting component, the rotating rod 55 will stop rotating after rotating to a certain angle; when the scraping of the soil stops, under the action of the limiting component, the rotating rod 55 will rotate in the direction of the connecting block 53. After rotating to a certain extent, the limiting component can limit the rotation of the rotating rod 55, that is, at this time the rotating rod 55 is in its natural state.

[0052] Specifically, a third connecting member is fixedly connected to one side of the rotating rod 55 near the second connecting member; the limiting component passes through the first connecting member 54 to the third connecting member and is connected to the third connecting member. The cooperation between the second and third connecting members fixes the limiting component. Since the third connecting member is fixed on the rotating rod 55, the limiting component limits the rotation rod 55.

[0053] Furthermore, the limiting component includes a buffer shaft 571, which passes through the second connector to the third connector and is fixed on the third connector; a first spring 572 sleeved on the buffer shaft 571 and located above the second connector; and a second spring 573 sleeved on the buffer shaft 571 and located between the second connector and the third connector. In addition to limiting the rotation of the rotating rod 55, the first spring 572 and the second spring 573 also act as a buffer for the rotating rod 55. Specifically, when the scraper is scraping the soil, it rotates away from the connecting block 53. At this time, the rotating rod 55 drives the buffer shaft 571 to move, and the first spring 572 is compressed. After the first spring 572 is compressed to a certain extent, the rotating rod 55 stops rotating. Due to the unevenness of the ground during the scraping process, the rotating rod 55 will be driven by the scraper to rotate slightly back and forth. The use of the first spring 572 can buffer the rotation of the rotating part. When the scraper stops scraping the soil, there is no soil thrust on the scraper. Under the action of the elastic force of the first spring 572, the buffer shaft 571 drives the rotating rod 55 to rotate towards the connecting block 53. At this time, the second spring 573 not only limits the rotation of the rotating rod 55, but also provides a buffer force for the rotating rod 55 to prevent the rotating rod 55 from rotating too much.

[0054] In one specific example, the top of the buffer rod includes a stop 574, and the first spring 572 is located between the stop 574 and the second connector. The use of the stop 574 can confine the first spring 572 between the stop 574 and the second connector.

[0055] Furthermore, the second connector includes two opposing second fixing plates 561, which are connected by a connecting shaft 562; the connecting shaft 562 includes a through hole; a third connector is fixedly connected to one side of the rotating rod 55 near the second connector; the third connector includes two opposing third fixing plates 581; the buffer shaft 571 passes through the through hole to the space between the two third fixing plates 581, and the bolt 582 passes sequentially through one of the fixing plates 581, the buffer rod, and the other fixing plate 581; the second spring 573 is constrained between the connecting shaft 562 and the bolt 582.

[0056] In one specific embodiment, the frame includes a main frame 1 and an auxiliary frame 2 connected and fixed to the main frame 1, with the auxiliary frame 2 located above the main frame 1. The main frame 1 has a first mounting member 11, preferably two, for mounting on the vehicle on the side closest to the vehicle; the auxiliary frame 2 has a second mounting member 12 for mounting on the vehicle on the side closest to the vehicle. The arrangement of the main frame 1, auxiliary frame 2, first mounting member 11, and second mounting member 12 makes the connection between the entire trench filling device and the vehicle more stable. In practical applications, the second mounting member 12 can be connected to the vehicle via a hydraulic rod. When the trench filling device is needed, the hydraulic rod moves the entire device downwards so that the loosening board and scraper can work normally; when the trench filling device is not needed, the hydraulic rod moves the entire device upwards so that the loosening board and scraper are lifted off the ground, allowing the vehicle to transport the entire device.

[0057] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
