Abstract
Description
Technical Field
[0001] This invention relates to the field of bulldozer equipment technology, and more specifically to a bulldozer blade mechanism. Background Technology
[0002] Conventional bulldozers can level roads using their buckets and breakers, but when constructing river channels, in addition to leveling the riverbed surface, they also need to pile soil and level the slopes on both sides. Conventional bulldozers have significant drawbacks: 1. Low efficiency in ditch construction: Slope building requires manual labor, severely slowing down the project. 2. Insufficient slope compaction precision: Loose soil is prone to collapse when directly piled, requiring secondary manual adjustments, and insufficient slope compaction affects structural stability. 3. Difficulty unloading wet soil: Wet soil in river channels easily adheres to the inner wall of the bucket, resulting in incomplete unloading and increased cleaning frequency. 4. Cumbersome maintenance of breaking components: Replacing worn-out toothed spikes is time-consuming, affecting equipment utilization.
[0003] Therefore, there is an urgent need for a bulldozer blade mechanism to solve the above problems. Summary of the Invention

The push plate is connected to the telescopic end of the hydraulic rod.
[0006] Based on the above technical solution, the present invention can be further improved as follows.
[0007] Furthermore, the push plate has an internal mounting cavity, and an electric heating wire is installed inside the mounting cavity.
[0008] Furthermore, the electric heating wire is arranged in a continuous S-shape within the mounting cavity.
[0009] Furthermore, it also includes a side bucket mechanism, which comprises: Two side plates are respectively hinged to both sides of the bucket; A vertical plate is fixedly installed on the back of the bucket; Two connecting rods are symmetrically fixed to the outer sides of the two side plates, respectively; Two sets of hydraulic rods, one end of each set of hydraulic rods is hinged to the corresponding side of the top of the vertical plate, and the other end is hinged to the corresponding connecting rod. The length of the side plate is equal to half the length of the bucket back, and the side plate can rotate between the open position and the closed position of the bucket under the four-wheel drive of the hydraulic rod.
[0010] Furthermore, it also includes a soil discharge assembly; the bottom wall of the bucket is provided with a through groove extending along its width direction; The soil discharge assembly includes a bottom pipe, two spiral impellers, two motors, and two vertical pipes; The bottom tube is horizontally positioned below the through groove of the bucket. The upper half of the bottom tube has a discharge hole that communicates with the inside of the bucket, and the lower half of its wall has a closed structure to seal the through groove. The two spiral impellers are coaxially arranged inside the bottom tube and are located at both ends of the bottom tube. The two motors are respectively fixed at both ends of the axial direction of the bottom tube, and their output shafts extend into the bottom tube to drive and connect to the corresponding spiral impellers. The bottom ends of the two vertical tubes are respectively connected to the end regions of both ends of the bottom tube, and the end regions are located at the end of the bottom tube closer to the motor.
[0011] Furthermore, the soil removal assembly also includes a second spiral impeller and a second motor; The second spiral impeller is installed inside the vertical pipe, and the bottom end of the second spiral impeller extends into the bottom pipe; The second motor is fixedly installed at the top of the vertical pipe, and the output end of the second motor is connected to the second spiral impeller for transmission. Furthermore, the soil discharge assembly also includes rectangular tube one and rectangular tube two; The rectangular tube is inserted into the top of the vertical tube, and its extension direction is away from the bucket; The second rectangular tube is slidably connected to the end of the first rectangular tube away from the vertical tube, and can move along the length of that end.
[0012] Furthermore, a plurality of limiting holes are evenly provided on the first rectangular tube, and a plug rod that is threaded and connected to the limiting holes is installed on the end of the second rectangular tube near the first rectangular tube.
[0013] Furthermore, it also includes a shovel tooth assembly, which includes a T-shaped insert that is slidably fitted into a T-shaped groove at the bottom of the front wall of the bucket; multiple toothed pins are fixed to the side of the T-shaped insert away from the bucket.
[0014] Furthermore, both ends of the T-shaped insert are provided with threaded through holes, and corresponding limit screws that are screwed into the threaded through holes are provided on the side walls of the bucket.
[0015] Furthermore, the present invention also includes a method for operating a bulldozer blade mechanism, comprising the following steps: S1. Flat shovel: The connecting arm is driven to get close to the road surface by the shovel lifting mechanism, and the bucket is adjusted to keep it vertical. Then the bucket follows the movement of the bulldozer and uses the shovel tooth assembly to shovel soil on the road surface. When it is necessary to discharge soil to both sides, the soil discharge assembly on both sides of the bottom tube is activated to discharge soil to both sides of the bucket. S2. Soil preparation: After shoveling, the bucket is adjusted by the shovel lifting mechanism to tilt it upwards, and then the bucket opening is closed by the side bucket mechanism. After closing, the soil discharge mechanism is used to compress and prepare the soil layer inside the bucket. S3. Slope Soil Pile: After the soil preparation is completed, the bucket is lifted to the riverbank slope using the shovel lifting mechanism. Then, the bucket opening is controlled to face downwards. The bucket opening is opened by controlling the side bucket mechanism. Then, the soil layer in the bucket is piled on the riverbank slope using the soil removal mechanism. S4, Soil compaction: After the soil is piled up on the slope, the soil layer is compacted on the slope using the soil removal mechanism. After compaction, the bottom of the bucket is controlled by the shovel lifting mechanism to compact the soil layer on the slope.
[0016] The beneficial effects of this invention are: 1. In this embodiment, the push plate of the soil removal mechanism has an S-shaped electric heating wire built in, which can heat and prevent the wet soil from sticking together. Combined with the hydraulic rod driving the push plate to squeeze the soil, the soil removal efficiency and the compaction of the slope soil are significantly improved.
[0017] 2. In this embodiment, the side bucket mechanism controls the opening and closing of the side plates through hydraulic rods. When closed, it works in conjunction with the soil removal mechanism to compact the soil inside the bucket, forming a regular block. When opened, it accurately feeds material onto the slope, ensuring the stability of the pile structure.
[0018] 3. In this embodiment, the T-shaped insert of the shovel tooth assembly is fixed to the T-slot of the bucket by a limiting screw. After the tooth pins wear out, they can be quickly disassembled and replaced, reducing downtime.
[0019] 4. In this embodiment, the bottom pipe is connected through the bottom groove of the bucket. The spiral impeller of the soil discharge component divides the soil to both ends. After being lifted by the vertical pipe, the soil is discharged to both sides of the ditch by the adjustable rectangular pipes one and two, which reduces the lifting and unloading action of the bucket and shortens the operation cycle.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0024] In the description of this application, the term "for example" is used to mean "used as an example, illustration, or description." Any embodiment described as "for example" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to make and use the invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the invention can be made without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the invention with unnecessary detail. Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.
[0025] Example 1 This embodiment provides a bulldozer blade mechanism, such as... Figure 1-6 As shown, it includes a bucket 1, a lifting mechanism 3, and a soil removal mechanism 4; The bucket 1 is connected to both sides of the lifting mechanism 3 via connecting arms 11, and is driven to rotate around a horizontal axis; one end of the connecting arm 11 is connected to the lifting mechanism 3, and the other end is equipped with a connecting seat 12 for docking with a bulldozer, and the connecting arm 11 is rotatably connected to the connecting seat 12. The shovel lifting mechanism 3 includes: two sets of hydraulic rods 31, two sets of hydraulic rods 32, a support frame 33, and a support base 34; Two sets of hydraulic rods 31 are symmetrically arranged on the inner side of the connecting arm 11; one end of the hydraulic rod 31 is hinged to the connecting arm 11, and the other end is hinged to the outer wall of the bucket 1. The two sets of hydraulic rods 32 are respectively hinged to the outer side wall of the connecting arm 11; The support frame 33 is fixedly connected to the end of the hydraulic rod 32 away from the connecting arm 11; The support base 34 is detachably mounted on the bulldozer and is rotatably connected to the support frame 33; The soil removal mechanism 4 is installed inside the bucket 1, and the soil removal mechanism 4 includes a hydraulic rod 41 and a push plate 42; The hydraulic rod 41 is symmetrically installed on the back of the bucket 1, and its telescopic end extends into the interior of the bucket 1; The push plate 42 is connected to the telescopic end of the hydraulic rod 41.
[0026] It should be noted that when the lifting mechanism 3 is in use, if it is necessary to adjust the tilting state of the bucket 1, the bucket 1 is rotated around the hinge axis (horizontal axis) between itself and the front end of the connecting arm 11 by controlling the extension and retraction of the two sets of symmetrically arranged hydraulic rods 31, thereby achieving the tilting action of the bucket 1. When it is necessary to adjust the working height of the bucket 1, the connecting arm 11 is rotated around the hinge point between itself and the connecting seat 12 by controlling the extension and retraction of the two sets of hydraulic rods 32, thereby raising or lowering the overall position and height of the bucket 1 and its connecting mechanism.
[0027] In a preferred embodiment, such as Figure 6 As shown, the push plate 42 has an internal mounting cavity 401, and an electric heating wire 421 is installed inside the mounting cavity 401. The electric heating wire 421 is arranged in a continuous S-shape within the mounting cavity 401.
[0028] In this embodiment, after pushing the damp soil layer at the bottom of the river, the electric heating wire 421, which is arranged in an S-shape in the mounting cavity 401, is connected to the electric system of the bulldozer. In this way, the electric heating wire 421 is used to heat the push plate 42, which prevents the damp soil from sticking to the push plate 42 and improves the soil removal efficiency of the soil removal mechanism 4.
[0029] In a preferred embodiment, such as Figure 1-6As shown, it also includes a side bucket mechanism 5, which comprises: Two side plates 51 are respectively hinged to both sides of the bucket 1; Vertical plate 52 is fixedly installed on the back of the bucket 1; Two connecting rods 54 are symmetrically fixed to the outer sides of the two side plates 51, respectively; Two sets of hydraulic rods 53, one end of each set of hydraulic rods 53 is hinged to the corresponding side of the top of the vertical plate 52, and the other end is hinged to the corresponding connecting rod 54. The length of the side plate 51 is equal to half the length of the bucket back of the bucket 1. The side plate 51 can rotate between the open position and the closed position of the bucket 1 under the drive of the hydraulic rod 4 53.
[0030] In this embodiment, it should be noted that when the side bucket mechanism 5 is in use, the hydraulic rod 53 is extended and retracted, and then the connecting rod 54 pulls the side plate 51 to rotate around both sides of the bucket 1, thereby completing the closure of the bucket opening of the bucket 1.
[0031] It is worth noting that when shoveling soil on the ground in the bucket 11, the adjustable side plate 51 can be rotated outward to increase the shoveling range of the bucket 1, making it easier for soil to enter the bucket 1, so that there is enough soil in the bucket 1, which is convenient for later compaction and shaping of the soil.
[0032] In a preferred embodiment, such as Figure 5 As shown, it also includes a shovel tooth assembly 2, which includes a T-shaped insert 21. The T-shaped insert 21 is slidably embedded in a T-shaped groove opened at the bottom of the front wall of the bucket 1. Both ends of the T-shaped insert 21 are provided with threaded through holes, and corresponding positions on the side walls of the bucket 1 are provided with limiting screws 22 that are screwed into the threaded through holes. Multiple toothed nails 23 are fixedly connected to the side of the T-shaped insert 21 away from the bucket 1.
[0033] In this embodiment, when the shovel tooth assembly 2 is used, the T-shaped insert 21 is inserted into the T-shaped groove opened at the bottom front side of the bucket 1. After insertion, the limiting screws 22 at both ends of the bucket 1 are screwed into the threaded through holes opened in the T-shaped insert 21 to complete the installation and fixation. This makes it easy to disassemble the shovel tooth assembly 2 later for replacement or repair. After installation, when the shovel tooth assembly 2 moves, the tooth nails 23 are used to break the soil, making it easy for the bucket 1 to shovel soil.
[0034] The working principle of the bulldozer blade mechanism and its operating method provided by this invention is as follows: In use, the bucket 1 is mounted on the front side of the bulldozer via the connecting seat 12 on the connecting arm 11. Then, the shovel tooth assembly 2 is mounted on the lower front edge of the bucket 1. The lifting mechanism 3, the soil removal mechanism 4, and the side bucket mechanism 5 are connected to the bulldozer's hydraulic control system. The lifting mechanism 3 drives the bucket 1 close to the road surface, and the bulldozer pushes the bucket 1 to move. The shovel tooth assembly 2 shovels soil from the road surface into the bucket 1. After the bucket 1 is loaded, the side bucket mechanism 5 is activated to close the bucket opening of the bucket 1. After closing, the bucket opening of the bucket 1 is kept horizontally upwards. Then, the... The hydraulic rod 41 of the moving soil removal mechanism 4 drives the push plate 42 to push the soil in the bucket 1 upward, compressing and straightening the soil in the bucket 1. After straightening, it is lifted to the riverbank slope. Then, the bucket opening of the bucket 1 is controlled to face downward. The bucket opening of the bucket 1 is opened by the control side bucket mechanism 5. The hydraulic rod 41 is further controlled to drive the push plate 42 to push the soil in the bucket 1 onto the riverbank slope. After stacking, it is further pressed down. After pressing down, the bottom of the bucket 1 is driven by the lifting mechanism 3 to compact the soil layer on the riverbank slope, thereby completing the efficient stacking of the riverbank slope. Furthermore, when the bucket 1 is shoveling soil forward, it needs to discharge soil to both sides directly to the sides of the river or ditch (the width of the river or ditch is adapted to the width of the bucket 1). The motor 1 71 is started to drive the spiral impeller 1 72 to rotate, transporting the soil that has fallen into the channel 101 from the bucket 1 to one side of the bottom pipe 6. Then, the motor 2 74 is started to drive the spiral impeller 2 75 to rotate, transporting the soil in the bottom pipe 6 to the vertical pipe 73, and then discharging it from the rectangular pipe 1 76 and the rectangular pipe 2 77. The rectangular pipe 2 77 can slide along the rectangular pipe 1 76 to adjust the position of the soil discharge. Thus, the bucket 1 does not need to discharge the soil from the outside, and the soil in the bucket 1 can be quickly discharged to the slope. This reduces the need for repeated loading and unloading of soil in the bucket 1, thereby improving the efficiency of river and ditch excavation and reducing the difficulty of operation for workers.
[0035] Example 2 This embodiment provides a bulldozer blade mechanism, which adds a soil discharge component 7 to the basis of embodiment 1.
[0036] like Figure 7-12 As shown, the bottom wall of the bucket 1 is provided with a through groove 101 extending along its width direction; The soil discharge assembly 7 includes a bottom pipe 6, two spiral impellers 72, two motors 71, and two vertical pipes 73; The bottom pipe 6 is horizontally arranged below the through groove 101 of the bucket 1. The upper half of the bottom pipe 6 is provided with a discharge hole that communicates with the inside of the bucket 1, and its lower half of the wall is a closed structure to close the through groove 101. The two spiral impellers 72 are coaxially arranged inside the bottom tube 6 and are located at both ends of the bottom tube 6. The two motors 71 are respectively fixed at both ends of the axial direction of the bottom tube 6, and their output shafts extend into the bottom tube 6 to drive the corresponding spiral impellers 72. The bottom ends of the two vertical tubes 73 are respectively connected to the end regions of both ends of the bottom tube 6, and the end regions are located at the end of the bottom tube 6 near the motor 71.
[0037] Specifically, the soil discharge assembly 7 also includes a spiral impeller 75 and a motor 74; The second spiral impeller 75 is installed inside the vertical tube 73, and the bottom end of the second spiral impeller 75 extends into the bottom tube 6; The second motor 74 is fixedly installed at the top of the vertical pipe 73, and the output end of the second motor 74 is connected to the second spiral impeller 75 for transmission. In a preferred embodiment, such as Figure 12 As shown, the soil discharge assembly 7 also includes a first rectangular tube 76 and a second rectangular tube 77; The rectangular tube 76 is inserted into the top of the vertical tube 73, and its extension direction is away from the bucket 1; The second rectangular tube 77 is slidably connected to the end of the first rectangular tube 76 away from the vertical tube 73, and can move along the length of that end.
[0038] The rectangular tube 76 has several limiting holes 701 evenly distributed on it, and the rectangular tube 77 has a threaded rod 771 that is connected to the limiting holes 701 at one end near the rectangular tube 76.
[0039] It should be noted that in this embodiment, when the bucket 11 is shoveling soil forward, it needs to discharge soil to both sides directly to the sides of the river or ditch (the width of the river or ditch is adapted to the width of the bucket 11). The motor 1 71 is started to drive the spiral impeller 1 72 to rotate, and the soil falling into the channel 101 in the bucket 1 is transported to one side of the bottom pipe 6. Then the motor 2 74 is started to drive the spiral impeller 2 75 to rotate, and the soil in the bottom pipe 6 is transported to the vertical pipe 73 and discharged from the rectangular pipe 1 76 and the rectangular pipe 2 77. The rectangular pipe 2 77 can slide along the rectangular pipe 1 76 to adjust its length, and is fixed by rotating the insertion rod 771 at its end to the limiting hole 701 on the rectangular pipe 1 76, thereby precisely controlling the soil discharge position. Thus, the bucket 1 does not need to discharge the soil in the bucket 1 externally, and can quickly discharge the soil in the bucket 1 to the slope. This reduces the original repeated operation of loading and unloading soil in the bucket 1, thereby improving the efficiency of river and ditch excavation and reducing the difficulty of operation for workers.
[0040] A method for operating a bulldozer blade mechanism includes the following steps: S1, Flat Shovel: The connecting arm 11 is driven to get close to the road surface by the lifting mechanism 3, and the bucket 1 is adjusted to keep it vertical. Then the bucket 1 follows the movement of the bulldozer and uses the shovel tooth assembly 2 to shovel soil on the road surface. When it is necessary to discharge soil to both sides, the soil discharge assembly 7 on both sides of the bottom pipe 6 is activated to discharge soil to both sides of the bucket 1. S2, Soil Preparation: After the soil shoveling operation, the bucket 1 is adjusted by the shovel lifting mechanism 3 to make it flip upward. Then, the bucket opening of the bucket 1 is closed by the side bucket mechanism 5. After closing, the soil discharge mechanism 4 is used to squeeze and prepare the soil layer in the bucket 1. S3. Slope Soil Pile: After the soil preparation is completed, the shovel lifting mechanism 3 is used to lift the bucket 1 to the riverbank slope. Then, the bucket opening of the bucket 1 is controlled to face downwards. The bucket opening of the bucket 1 is opened by the side bucket mechanism 5. Then, the soil layer in the bucket 1 is piled on the riverbank slope by the soil removal mechanism 4. S4, Soil compaction: After the soil is piled up on the slope, the soil layer is compacted on the slope by the soil removal mechanism 4. After compaction, the bottom of the bucket 1 is controlled by the shovel lifting mechanism 3 to compact the soil layer on the slope.
