Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, in particular to a bidirectional branch-chopping mower. Background Art

[0002] A brush chipper or lawn mower is a common agricultural machine. A large lawn mower or brush chipper driven by a tractor can usually clean a large area.

[0003] After felling a plantation forest, large piles of heavily packed branches are left behind. These branches are of various shapes, with large gaps between them, making the piles fluffy and large in size.

[0004] To clean up such a pile of branches, traditional mowers encounter the following problems:

[0005] 1. The bottom of the mower is too close to the ground, making it impossible to effectively roll branches into the mower for shredding.

[0006] 2. After the first shredding, the branches are still large and need to be shredded again. During the second shredding, the tractor needs to turn around to shred the branches. However, in plantations with complex terrain, there is little space for tractors to turn around, making it impossible to perform the second shredding operation.

[0007] Similarly, traditional lawn mowers will encounter similar problems when faced with densely packed and very tall weeds.

[0008] Therefore, there is an urgent need for a lawn mower that can effectively roll branches or weeds into the interior and does not require a turning operation to overcome the above-mentioned problems. Summary of the Invention

[0010] Shell,

[0011] A forward guide mechanism, rotatably connected to one side of the housing,

[0012] The reverse guide mechanism is fixedly arranged on the other side of the housing.

[0013] A branch crushing mechanism is installed inside the shell.

[0014] The power mechanism includes a hydraulic power mechanism and a mechanical power mechanism. The hydraulic power mechanism is fixedly connected to the forward guide mechanism and drives it to lift or lower. The mechanical power mechanism is connected to the branch shredding mechanism and drives it to rotate.

[0015] The support frame is fixed above the shell and is driven to rise, fall or move horizontally by an external power.

[0016] Furthermore, the housing comprises:

[0017] Upper enclosure plate,

[0018] Side panels, the side panels are arranged on both sides of the upper surrounding panel, and the branch crushing mechanism is rotatably arranged between the side panels.

[0023] A connecting plate, one end of which is fixedly connected to the top of the base shell, and the other end of which is hinged to the outer shell or the oil pressure power mechanism.

[0024] Furthermore, the reverse guiding mechanism includes:

[0025] A connecting frame, the connecting frame is fixedly connected to the housing,

[0026] A roller is arranged on the connecting frame.

[0027] Furthermore, the oil pressure power mechanism includes:

[0028] A hinge seat, the hinge seat is fixed to the upper surface of the shell, and the bottom of the hinge seat is hinged to the bottom end of the connecting plate.

[0029] An oil cylinder, one end of which is hinged to the top of the hinged seat, and the other end of which is hinged to the top of the connecting plate.

[0030] Furthermore, the mechanical transmission mechanism includes:

[0031] A gear box is fixed to the top of the upper enclosure plate.

[0032] The transmission box is fixed to the outside of the side plate, and the transmission box drives the branch shredding mechanism to rotate through a pulley.

[0033] The transmission shaft is arranged between the gear box and the transmission box.

[0034] Furthermore, the support frame includes:

[0035] A mounting plate is provided on the top of the upper enclosure plate.

[0061] The following is a guide based on the ideal embodiments of the present invention. Through the following description, relevant personnel can make various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.

[0062] With reference to the following drawings, the housing 10, the forward guide mechanism 20, the reverse guide mechanism 30, the branch shredding mechanism 40, the power mechanism and other components of the present invention and the connection relationship therebetween will be further described:

[0063] refer to Figure 1, is a schematic diagram of the three-dimensional structure of the present invention. It generally comprises a housing 10, a forward guide mechanism 20, a reverse guide mechanism 30, a branch shredder mechanism 40, a support frame 50, and a power mechanism 60. The rear end of the support frame 50 is typically connected to a tractor boom, which drives the support frame 50 upward, downward, or horizontally. The tractor also acts as a propeller, pushing or pulling the present invention forward or backward.

[0064] During forward movement, the forward guide mechanism 20 opens, widening the mower's opening and allowing more branches to enter the shredder mechanism 40 for crushing, completing the first shredding operation. After the first shredding operation is complete, the forward guide mechanism 20 closes, and the tractor uses the reverse guide mechanism 30 to pull the mower backward, re-entering the pre-crushed branches into the shredder mechanism 40 for a second shredding operation, forming smaller particles that facilitate degradation or movement.

[0065] refer to Figure 1-3 The housing 10 has an upper enclosure panel 11 and side panels 12. The upper enclosure panel 11 is stepped and has an inclined side. In the actual implementation process, the upper enclosure panel 11 is generally formed in one piece, but it can also be formed by welding. The side panels 12 are fixed on both sides of the upper enclosure panel 11. The present invention adopts a screw fixing method for fixing. Figure 1 The shapes of the side panels 12 on the left and right sides are slightly different. The top of the left side panel 12 is consistent with the side shape of the upper surrounding panel 11; the right surrounding panel exceeds the upper surrounding panel 11 by a certain height, which is convenient for the subsequent installation of the support frame 50 and the outer transmission box 622.

[0066] refer to Figure 1-3 The lower surface of the upper enclosure panel 11 is also provided with multiple reinforcing plates 111 arranged along the shape of the upper enclosure panel 11. These plates serve to strengthen the upper enclosure panel 11 and effectively prevent branches from getting stuck. The reinforcing plates 111 utilize a multi-segment tubular structure, which effectively increases the strength of the upper enclosure panel 11.

[0067] refer to Figure 1-3 , a guide plate 13 with two raised ends is fixed under the side plate 12. Figure 1 The guide plate 13 is formed as a whole by a bottom plate with two ends bent close to the ground and a side plate next to the bottom plate. The side plate is fixed to the side plate 12 by screws. Among them, the warping on both sides of the bottom plate is curved. Traditional lawn mowers do not have this design. Traditional lawn mowers only have one end warping and can only operate in one direction. The design purpose of the guide plate 13 is: when the branch mower moves forward or backward, when encountering piles of branches, the warped part can guide the branch mower to pass quickly, thereby reducing the jamming during passage, and greatly enhancing the passability of this product in the face of complex road conditions.

[0068] refer to Figure 1-2 At the bottom of one side of the upper enclosing plate 11 near the reverse guide mechanism 30, a rotatable multi-piece guide curtain 14 is also installed. The number of guide curtains 14 is determined by the length of the upper enclosing plate 11 and the width of the guide curtain 14. The guide curtain 14 itself is a metal sheet with two parallel long strips of grooves dug out on it to reduce its own weight. The top of the guide curtain is provided with a sleeve, which is sleeved on the pin shaft below the upper enclosing plate 11 (not shown in the figure). The purpose of setting the guide curtain 14 is that when the tractor is working in the forward direction, the guide curtain swings with the height of the grass and guides it into the machine. After being introduced, the broken branches, grass roots and soil flying out are blocked in the reverse direction, which serves as a safety protection.

[0069] refer to Figure 3 A reinforcing rib 121 is provided on the inner side of the side panel 12 to reduce the vibration fluctuation of the side panel 12 during the operation of the machine, thereby enhancing the rigidity of the side panel 12 and the entire housing 10.

[0070] refer to Figure 1 、 Figure 3 The forward guide mechanism 20 includes a base shell 21. The middle section of the base shell 21 is an arch-shaped middle section plate with extension plates on both sides. The inner side of the extension plate is fixed with a fixed plate by screws. The roller 22 and the scraper 23 are rotatably connected between the fixed plates. When the machine is operating, especially when working on wet soil, the scraper 23 scrapes off the mud on the roller 22, limits the thickness of the mud on the roller 22, and ensures the normal operation of the roller 22.

[0071] The drum 22 is rotatable. When the forward guide mechanism 20 is opened, the drum 22 plays a guiding role, guiding the high-positioned broken branches into the branch breaking mechanism 40. The provision of the scraper 23 also effectively reduces the probability of the drum 22 being damaged by collision.

[0072] refer to Figure 1 and Figure 3 The connecting plate 24 has a raised center that matches the shape of the top surface of the base shell 21. The raised center portion of the connecting plate 24 has a hole for hinged connection with the hydraulic power mechanism 61. The bottom portion of the connecting plate 24 extends obliquely downward and is hinged to an extended portion of the top surface of the upper enclosure plate 11 or to the bottom of the hydraulic power mechanism 61. The hydraulic power mechanism 60 drives the opening and closing of the forward guide mechanism 20.

[0073] refer to Figure 1The reverse guide mechanism 30 comprises a connecting frame and rollers. A side plate at one end of the connecting frame is fixed, while the other end is secured via a pin and a portion extending from the top surface of the upper enclosure plate 11. The other end of the connecting frame is rotatably connected to a roller. The reverse guide mechanism 30 primarily prevents the forward guide mechanism 20 from tilting due to uneven road conditions during reverse travel, potentially damaging or breaking the connection between the tractor and the support frame 50.

[0074] refer to Figure 1-2 The hydraulic power mechanism 61 includes an articulated seat 611 and an oil cylinder 612. The side shape of the articulated seat 611 is shown in FIG. Figure 3 As shown, its bottom surface spans the two steps of the upper enclosure plate 11. The top is hinged to the end of the cylinder 612, and the bottom is hinged to the aforementioned connecting plate 24. The other end of the cylinder 612 is hinged to the raised portion in the middle of the top of the connecting plate 24. When the cylinder 612 is retracted, the forward guide mechanism 20 is opened, and vice versa.

[0075] refer to Figure 4 The oil cylinder 612 is driven by external hydraulic power. A hydraulic lock 613 is also installed on the upper enclosure plate 11. The oil circuits A, B, and C are the oil inlet circuits, and the oil circuits D, E, and F are the oil outlet circuits. This arrangement ensures that when oil is inlet or outlet, the oil cylinders 612 on both sides are controlled by the same valve, improving the synchronization of the oil cylinders 612 on both sides.

[0076] refer to Figure 1 and 2 The mechanical power mechanism 62 includes a gear box 621, a transmission box 622 and a transmission shaft 623. An opening is provided on one side of the gear box 621, through which the power source on the tractor can be connected, and then the power is sent to the transmission box 622 through the transmission shaft 623. Figure 1 The gear box 621 is fixed to the top of the upper enclosing plate 11, and a reinforcing plate 624 is provided on its side to prevent the gear box 621 from falling off. The transmission box 622 is arranged on the outside of the side plate 12, and has a pulley inside, which drives the wood chipping mechanism to rotate through the pulley.

[0077] Reference Figure 1 、 Figure 2 and Figure 4 The support frame 50 includes a mounting plate 51, a support shaft 52, and an arch frame 53. The mounting plate 51 is set on the top surface of the upper enclosure plate 11, and the support shaft 52 is installed between the mounting plate 51 and the side plate 12. The bottom ends of the two sides of the arch frame 53 are sleeved on the support shaft 52, and the top end is fixed to the external tractor's force arm.

[0078] In this embodiment, the support frame also includes an expansion seat and a transverse cylinder. The expansion seat is installed on the outside of the side panel, the support shaft is mounted on the expansion seat and can move outward, and the transverse cylinder is arranged on the top of the upper enclosure plate parallel to the support shaft, and its end is fixed to the support shaft and drives the transverse movement of the support shaft.

[0079] refer to Figure 1 and Figure 2 When the machine wants to move left or right, the lateral cylinder drives the support shaft to move left or right. Without the expansion seat with an opening, the support shaft will not be able to move horizontally in a large range. The lateral cylinder is connected to the hydraulic mechanism of the external tractor.

[0080] Reference Figure 1 and Figure 4 A connecting arm 55 is also fixed to the rear side of the top of the arch frame 53, and the connecting arm 55 is connected to the reinforcing shaft 56 between the two bearing seats, so that the force of the present invention is more uniform when in use.

[0081] refer to Figure 3 and Figure 5 The rotating shaft 41 is movably arranged between the two side plates 12 and is driven by the transmission box 622 on the side. A number of movable knives 42 are evenly arranged on the rotating shaft 41. The movable knives 42 are shovel-shaped with sharp ends. The movable knives 42 have a hinged base. When not in operation, the movable knives 42 naturally hang down. When in operation, they rotate with the rotating shaft 41 to be activated.

[0082] In addition, reference Figure 3 In this embodiment, fixed blades 43 are also provided. Multiple fixed blade groups are arranged side by side, each group having three fixed blades 43 fixed below the reinforcing plate 111. The coordination of the movable blades 42 and the fixed blades 43 allows the machine to achieve higher efficiency and more thorough shredding when shredding branches or mowing grass.

[0083] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
