Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery and equipment technology, specifically a land reclamation machine. Background Technology

[0002] Reclamation machines are mainly used for clearing land in mountainous and forested areas, using rotating rollers to break up and clear thorns and bushes. Existing reclamation machines have the following technical problems:

[0003] Firstly, the outer part of the roller is welded with crushing teeth or claws to use rotational power to grab and rake vegetation, achieving the purpose of land reclamation. However, due to the complex working environment of this equipment, when encountering hard tree trunks or rocks, the protruding crushing teeth or claws are easily worn or even broken, affecting the service life of the equipment. For example, in the Chinese utility model patent with publication number CN214784272U, "A Land Reclamation Device for a Skid Steer Loader", the roller has land reclamation blades evenly distributed on the same side, and the land reclamation blades are completely suspended outside the roller, making them susceptible to wear or twisting from external forces. Especially when it rotates at high speed, it is more likely to be squeezed by foreign objects on the side, and the blades are more likely to bend. In severe cases, jamming may occur, causing the equipment to malfunction.

[0004] Secondly, the gap between the pioneering rotating part and the upper jaw plate fixed on it is not adjustable. It runs smoothly when clearing low grasslands or thorn bushes, but it is prone to jamming when clearing taller shrubs or groves, thus limiting its applicable scenarios.

[0005] Third, the equipment generates a lot of dust when breaking up vegetation, which obstructs the driver's view and seriously affects the safety of driving operations.

[0006] In view of this, a pioneering machine is proposed, which not only makes the pioneering structure more robust and durable, but also has a wide range of applications, smooth operation, and clear visibility, making driving and operation more convenient and safe. Summary of the Invention

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. The land clearing machine of this invention uses a drive mechanism to drive a clearing wheel mounted on a rotating shaft for land clearing and preparation. Several annular grooves are parallel to each other on the outer circumference of the clearing wheel, and crushing teeth are installed within these grooves. This design better protects the crushing teeth, and the connection between the crushing teeth and the clearing wheel is not affected by the force of side objects during high-speed rotation, reducing the risk of breakage. Furthermore, the annular grooves allow for further rotation, cutting, and crushing of materials.

[0024] The breaker tooth mounting rod is welded into the annular groove of the pioneer wheel. The breaker tooth body is bolted into the mounting screw hole of the breaker tooth mounting rod, allowing for easy replacement when worn out. Furthermore, breaker tooth bodies of different lengths and tooth shapes can be replaced according to pioneering needs, making it more convenient to use. The breaker tooth protrudes from and is tangentially positioned to the outer surface of the pioneer wheel. Combined with its rotational motion, it rapidly gnaws away at broken vegetation, greatly improving pioneering efficiency.

[0025] 2. The shovel builder consists of a fixed jaw plate and a movable jaw plate. Adjusting the entry space for the shovel wheel is achieved through a regulating cylinder, thus increasing the flexibility of the equipment. The equipment is equipped with dust prevention and suppression devices. Dust prevention is achieved through a tempered glass protective plate. Simultaneously, to ensure a good field of vision for the user during operation, the shovel builder is equipped with a cleaning and dust collection device. Dust collection modules located at four points (upper left, lower left, lower right, and upper right) in conjunction with dust collection bars ensure good visibility in the direction of travel, further guaranteeing safe operation. The dust collection bars are external extensions of the dust collection modules and can be designed as a "C" shape with suction from both sides or an "X" shape with four points connected, effectively combining dust suppression and flexibility.

[0026] 3. In the dust suppression device described in this equipment, the exhaust fan serves as the power source for dust collection. Unlike existing dust suppression devices that rely on periodic replacement of the filter, the dust suppression device in the slab builder utilizes a continuously circulating filter belt, directly removing dust through spraying, tailored to the actual operating environment. The working environment of the slab builder is highly dusty, and the equipment cannot accommodate a large dust suppression structure. Therefore, the filtered dust must be promptly removed due to the small size of the device. Since the filtered materials are mostly dust, plant debris, and other harmless substances, the device employs a "filter and remove as you go" approach. This method offers two advantages: firstly, it maintains good visibility within the designated area; secondly, it does not affect other equipment operating below, avoiding the corrosion and damage that can occur with traditional atomized dust suppression methods over long-term operation.

[0027] 4. This equipment features a rear baffle behind the pioneer wheel to prevent crushed material from affecting the driving vehicle behind. Furthermore, based on the experimental site conditions, the inventors suspended several crushing chains on the rear baffle, forming the first barrier that directly contacts the crushed material. This barrier is easy to replace after wear and effectively protects the rear baffle, extending the equipment's service life. The equipment adopts a split-type design, effectively improving the multi-purpose operation capability of the driving vehicle. It features a reasonable structural design, high operating efficiency, low maintenance costs, and is easy to promote and use. Attached Figure Description

[0042] like Figure 3 As shown, both the left support 6 and the right support 7 are inverted "V" shapes.

A cleaning and vacuuming device is installed between the rear rods of the left support 6 and the right support 7. The cleaning and vacuuming device includes an upper left vacuuming module 13, a lower left vacuuming module 14, an upper right vacuuming module 15, and a lower right vacuuming module 16.

[0044] like Figure 3 , 4 As shown in Figures 5 and 6, a vacuum cleaner bar 17 is installed between the upper left vacuum cleaning module 13 and the upper right vacuum cleaning module 15, or between the upper left vacuum cleaning module 13 and the lower right vacuum cleaning module 16, or vacuum cleaner bars 17 are installed on the upper left vacuum cleaning module 13, the lower left vacuum cleaning module 14, the upper right vacuum cleaning module 15, and the lower right vacuum cleaning module 16 respectively; the vacuum cleaner bar 17 is a hollow bar body with several vacuum holes 18 opened on the front side wall of the bar body. Figure 5 and Figure 6 The document describes two different connection methods for the vacuum cleaner bar 17, but the connection methods are not limited to these two forms.

[0045] like Figure 7As shown, the upper left vacuum cleaning module 13, lower left vacuum cleaning module 14, upper right vacuum cleaning module 15, and lower right vacuum cleaning module 16 each include an L-shaped vacuum cleaning function group. Each vacuum cleaning function group includes an L-shaped hollow outer shell 19. One end of the hollow outer shell 19 is fixed to the left support 6 or the right support 7, and the other end of the hollow outer shell 19 is open, with a vacuum cleaner bar 17 inserted into the open end. An air inlet filter 20 is installed at the open end of the hollow outer shell 19. An air outlet is opened on the bottom surface of the corner of the hollow outer shell 19, and an air outlet filter 21 is installed on the air outlet. An exhaust fan 22 is installed inside the hollow outer shell 19, and a filter belt 23 support is installed around the exhaust fan 22. The filter support includes four support rollers, and a filter belt 23 is fitted onto the four support rollers. The filter belt 23 between two support rollers is located behind the air inlet filter 20 and passes through... Airflow entering the hollow housing 19 through the inlet filter 20 is filtered by the filter belt 23 and then discharged through the outlet. A drive chamber is provided inside the hollow housing 19, and a drive roller 24 and two or more passive rollers 25 are provided inside the drive chamber. The drive roller 24 and the two or more passive rollers 25 clamp the filter belt 23 in a "W" shape. The drive roller 24 is connected to the motor shaft of the hub motor of the exhaust fan 22 through a gear transmission group and a belt transmission group. A cleaning chamber 38 is provided inside the hollow housing 19, and a filter belt cleaning device is provided inside the cleaning chamber 38. A drain outlet 39 is opened at the bottom of the cleaning chamber 38. The filter belt cleaning device includes a pair of high-pressure nozzles 26. The filter belt 23 passes through the cleaning chamber 38 and is positioned between the opposing high-pressure nozzles 26. The spray surfaces of the two high-pressure nozzles 26 are respectively aligned with the two sides of the filter belt 23. The high-pressure nozzles 26 are connected to a water tank through a spray pump.

[0046] To improve equipment flexibility, the builder is also equipped with an upper jaw plate. The upper jaw plate is divided into two parts: a fixed jaw plate and a movable jaw plate 4. The movable jaw plate 4 is moved by an angle adjustment cylinder 5 installed on the fixed jaw plate, thereby realizing the gap adjustment of the builder's feed inlet. This allows it to accommodate materials of different sizes and prevents dangerous situations caused by the material falling over.

[0047] Meanwhile, to prevent excessively tall materials from tipping over onto the drive vehicle under the action of the pioneer wheel 2, a left support 6 and a right support 7 are installed on the frame 1 to provide lateral obstruction; a tempered glass protective plate 9 separates the left support 6 and the right support 7; the materials tipping towards the vehicle will be blocked and cut by the plate saw 10 installed on the crossbar 8. The plate saw 10 slides laterally left and right in the plate saw mounting hole through the saw connecting rod 12 driven by the swing cylinder or servo motor. When the two plate saws move relative to each other, the working efficiency of the saw is further improved.

[0048] When the land clearing machine is in operation, it is first connected to the drive vehicle via a connecting hook or connecting arm on the mounting plate, thus enabling the land clearing equipment to move. The land clearing operation is driven by the drive motor 34, which rotates the drive pulley 31 at high speed. The drive pulley 31, located inside the transmission protective housing, further drives the driven pulley 32 via the transmission belt 33, ultimately causing the land clearing wheel 2 and its shaft to rotate at high speed. As the land clearing wheel 2 rotates, the breaking teeth 3, located within the annular groove 27, break up and decompose weeds, branches, and other debris on the ground in situ. The breaking tooth body 29 is fixed to the land clearing wheel 2 via a breaking tooth mounting rod 28. Due to its split structure, the breaking tooth body 29 can be easily replaced and repaired when damaged during long-term use. Driven by the high-speed pioneer wheel 2, the vegetation is grabbed by the crushing teeth 3 and moved backward at high speed, entering between the upper jaw plate and the pioneer wheel 2. Here, the vegetation is crushed, and then it continues to be conveyed backward until it is blocked by the crushing chain 36 and the rear baffle 35, falling to the ground. At the same time, foot pedals 37 are installed and fixed on the frame 1 on both sides of the rear baffle 35 for the user to stand on.

[0049] When dust suppression is required, according to the user's habits, the vacuum cleaner bar 17 is first preset between the upper left vacuum cleaning module 13 and the upper right vacuum cleaning module 15, and between the lower left vacuum cleaning module 14 and the lower right vacuum cleaning module 16, as follows: Figure 5 As shown. Alternatively, it can be done according to... Figure 6 As shown, a suction bar 17 is connected and installed between the upper left suction cleaning module 13 and the lower right suction cleaning module 16, and shorter independent suction bars 17 are installed on the lower left suction cleaning module 14 and the upper right suction module respectively. When the exhaust fan 22 is turned on, the outside airflow carrying dust enters the air inlet filter 20 of the hollow outer shell 19 through the suction hole 18, and is quickly discharged through the air outlet after being filtered by the filter belt 23. During the air intake circulation process, dust adheres to the filter belt 23, which is supported by four support rollers to form a rotating circulating filtration state. The power source of the filter belt 23 is transmitted from the exhaust fan 22 to the drive roller 24 by the gear transmission group and belt transmission group. The drive roller 24 and the passive roller 25 rotate under the mutual friction. During the rotation, the high-pressure nozzle 26 cleans the filter belt 23 in real time, thereby aggregating the dust and plant debris in the airflow and discharging it directly to the ground through the drain port 39. This method differs from other dust suppression equipment because it does not require centralized collection and periodic or quantitative discharge. This is because centralized collection requires large dust collection equipment, which increases the overall size of the equipment, thus limiting its operation, restricting the applicable site, and increasing production and maintenance costs.

[0050] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
