Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a double-drainage rotary tiller. Background Technology

[0002] The rotary tiller is the core working component of a rotary tiller. It usually consists of a blade cylinder and rotary blades arranged in multiple rows and columns. Its main function is to cut and break up the soil by rotating the rotary blades at high speed, and mix in stubble and straw to prepare a flat and fine seedbed for rice planting.

[0003] Traditional rotary tillers, while cutting the soil, also cut and pull up tough weeds and long straws, which are then thrown into the blade barrel as they rotate. This causes the blade barrel to easily become entangled with the straw during operation, which not only significantly increases the load on the tractor engine and fuel consumption, and reduces operating efficiency, but also damages the flatness of the field surface, affects the soil breaking effect, and leads to a decline in the quality of operation. Utility Model Content

[0004] The purpose of this invention is to provide a double-drainage rotary tiller that solves the problem of traditional rotary tillers easily getting tangled in straw during operation.

[0005] To achieve the above objectives, this utility model provides a double-drainage rotary tiller, including a blade cylinder and a rotary tillage assembly. The rotary tillage assembly includes a mounting base, a rotary tillage blade, a bolt, a nut, and a weed-controlling component. The mounting base is fixedly connected to the blade cylinder and sleeved on the blade cylinder. The mounting base is provided with a slot, which cooperates with the rotary tillage blade. The rotary tillage blade is connected to the mounting base and extends into the slot. The bolt is connected to the mounting base and passes through the mounting base and the rotary tillage blade. The nut is threadedly connected to the bolt and sleeved on the bolt. The weed-controlling component is disposed on the blade cylinder.

[0006] The weed-control component includes a stabilizing plate, a mounting plate, and a weed-control plate. The stabilizing plate is fixedly connected to the cutter cylinder and sleeved on the cutter cylinder. The mounting plate is fixedly connected to the cutter cylinder and sleeved on the cutter cylinder. The two ends of the weed-control plate are fixedly connected to the stabilizing plate and the mounting plate, respectively, and the weed-control plate is located between the stabilizing plate and the mounting plate.

[0007] The weed control board has grass-breaking protrusions, which are located on one side of the weed control board.

[0008] The weed-control component includes a grass-chopping blade and a blocking plate. The grass-chopping blade is fixedly connected to the blade cylinder and is disposed on the blade cylinder; the blocking plate is fixedly connected to the grass-chopping blade and is disposed on the grass-chopping blade.

[0009] The baffle plate has an L-shaped protrusion, which is disposed on the baffle plate and located at one end of the baffle plate.

[0010] This utility model discloses a double-drainage rotary tiller. In use, the rotary tiller blades are inserted into slots on the mounting base. Then, a bolt is passed through through holes in both the mounting base and the rotary tiller blades, exiting from the other end of the mounting base. The nut is then tightened onto the bolt, and the rotary tiller blades are installed on the mounting base. Multiple rotary tiller blades are then sequentially installed on the mounting base. After installation, the blade cylinder is connected to the power output shaft of the agricultural equipment. The agricultural equipment drives the blade cylinder to rotate, which in turn drives the mounting base to rotate. The mounting base then drives the multiple rotary tiller blades to rotate, cutting and breaking up the soil. During operation, the weed-prevention component blocks weeds and long straw flowing towards the blade cylinder, disrupting the adhesion conditions required for the weeds to entangle. This continuously prevents weeds from entangled and accumulating on the blade cylinder and mounting base throughout the entire operation, ensuring stable, efficient, and continuous rotary tillage.

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] First embodiment: Please see Figures 1 to 3 ,in Figure 1 This is a schematic diagram of the overall structure of a rotary tiller for a double-drainage field. Figure 2 This is a schematic diagram of the structure of the raised grass clippings. Figure 3 This is a schematic diagram of the bolt installation structure.

[0019] This utility model provides a double-drainage rotary tiller, including a blade cylinder 101 and a rotary tillage assembly 102. The rotary tillage assembly 102 includes a mounting base 103, rotary tillage blades 104, bolts 105, nuts 106, and a weed-prevention component 107. The weed-prevention component 107 includes a stabilizing plate 108, a mounting plate 109, and a weed-prevention plate 110. The weed-prevention plate 110 has grass-breaking protrusions 111. The weed-prevention component 107 prevents weeds and straw from getting tangled on the blade cylinder 101 or the mounting base 103 during operation. The aforementioned solution can be used to prevent grass from getting tangled on the blade cylinder 101 or the mounting base 103, and can also be used to prevent grass from getting tangled at the connection between the blade cylinder 101 and the power output shaft of the agricultural machinery.

[0020] In this specific embodiment, the interface of the cutter barrel 101 is a regular hexagon, and the cutter barrel 101 can be installed on agricultural equipment and driven by the power device of the agricultural equipment to achieve rotational operation.

[0021] The mounting base 103 is fixedly connected to the blade cylinder 101 and sleeved on the blade cylinder 101. The mounting base 103 has a slot 113 that mates with the rotary tiller blade 104. The rotary tiller blade 104 is connected to the mounting base 103 and extends into the slot 113. The bolt 105 is connected to the mounting base 103 and passes through both the mounting base 103 and the rotary tiller blade 104. The nut 106 is threadedly connected to the bolt 105 and sleeved on the bolt 105. The weed-prevention mechanism... The component 107 is disposed on the blade cylinder 101; multiple mounting bases 103 are disposed and evenly distributed on the blade cylinder 101, and each mounting base 103 is provided with three slots 113, so that three rotary tillers 104 can be mounted on one mounting base 103. The ends of the rotary tillers 104 are bent so that the rotary tillers 104 can efficiently cut into the soil during rotation and achieve a good soil turning effect. The mounting base 103 and the rotary tillers 104 are provided with through holes that cooperate with the bolts 105.

[0022] In use, the rotary tiller blade 104 is inserted into the slot 113 on the mounting base 103. Then, the bolt 105 is passed through the through holes on the mounting base 103 and the rotary tiller blade 104, so that the bolt 105 protrudes from the other end of the mounting base 103. At this time, the nut 106 is tightened on the bolt 105, and then the rotary tiller blade 104 is installed on the mounting base 103. Finally, multiple rotary tiller blades 104 are installed on the mounting base 103 in sequence. After installation, the blade cylinder 101 is connected to the power unit of the agricultural equipment. The output shaft is connected to drive the blade cylinder 101 to rotate via agricultural equipment. The blade cylinder 101 drives the mounting base 103 to rotate, and the mounting base 103 drives multiple rotary tillage blades 104 to rotate, cutting and breaking up the soil. During the operation, the weed-prevention component 107 blocks weeds and long straws flowing towards the blade cylinder 101, destroying the adhesion conditions required for the grass to entangle. Thus, it continuously prevents weeds from entangled and accumulating on the blade cylinder 101 and the mounting base 103 throughout the entire operation, ensuring that the rotary tillage operation is stable, efficient and continuous.

[0023] Secondly, the stabilizing plate 108 is fixedly connected to the cutter cylinder 101 and sleeved on the cutter cylinder 101; the mounting plate 109 is fixedly connected to the cutter cylinder 101 and sleeved on the cutter cylinder 101; the two ends of the weed-proof plate 110 are fixedly connected to the stabilizing plate 108 and the mounting plate 109 respectively, and the weed-proof plate 110 is located between the stabilizing plate 108 and the mounting plate 109; there are two stabilizing plates 108, which are respectively located at both ends of the cutter cylinder 101; the mounting plate 109 is located in the middle of the cutter cylinder 101; there are multiple weed-proof plates 110. The weed-proof plates 110 are installed by the stabilizing plate 108 and the mounting plate 109. The multiple weed-proof plates 110 form a protective structure on the outside of the cutter cylinder 101 to prevent grass from getting tangled on the cutter cylinder 101 and the mounting base 103 during operation.

[0024] Meanwhile, the weed control plate 110 has grass-breaking protrusions 111, which are disposed on one side of the weed control plate 110; a plurality of grass-breaking protrusions 111 are disposed on one side of the weed control plate 110 away from the cutter cylinder 101. Through the grass-breaking protrusions 111, when the weed control plate 110 rotates with the cutter cylinder 101, it can actively cut the long-fiber weeds and straws it comes into contact with; and break the easily entangled strip-shaped grass into short fragments. These grass fragments are easy to be thrown off or fall due to gravity, thereby further reducing the possibility of grass getting entangled on the cutter cylinder 101 and the mounting base 103.

[0025] Finally, the weed-prevention component 107 also includes an anti-tangling plate 112, which is fixedly connected to the stabilizing plate 108 and located on one side of the stabilizing plate 108. The anti-tangling plate 112 extends outward along the axial direction of the cutter cylinder 101 and blocks the grass at the connection between the cutter cylinder 101 and the power shaft to prevent the grass from tangling.

[0026] When using the dual-drainage rotary tiller of this embodiment, the agricultural machinery drives the blade cylinder 101 to rotate, which in turn drives the mounting base 103 and the rotary tiller blades 104 to rotate, so that the rotary tiller blades 104 cut and break up the soil. While the blade cylinder 101 rotates, it also drives the stabilizing plate 108, the mounting plate 109 and the weed-prevention plate 110 to rotate. The multiple weed-prevention plates 110 form a protective structure on the outside of the blade cylinder 101 to prevent grass from getting tangled on the blade cylinder 101 and the mounting base 103. At the same time, the grass-breaking protrusions 111 can cut the material, further preventing grass from getting tangled.

[0027] Second embodiment: Based on the first embodiment, please refer to Figure 4 , Figure 4 This is a schematic diagram of the overall structure of the double-drainage rotary tiller in the second embodiment. The weed control component 107 in this embodiment includes a weed shredder 201 and a baffle plate 202. The baffle plate 202 has an L-shaped protrusion 203.

[0028] In this specific embodiment, the grass-chopping blade 201 is fixedly connected to the blade cylinder 101 and is disposed on the blade cylinder 101; the baffle plate 202 is fixedly connected to the grass-chopping blade 201 and is disposed on the grass-chopping blade 201; multiple baffle plates 202 are provided, with one baffle plate 202 connected to three grass-chopping blades 201. The function of the baffle plate 202 in this embodiment differs from that of the grass-prevention plate 110 in the first embodiment in that the baffle plate 202 in this embodiment is mounted on the blade cylinder 101 through the grass-chopping blade 201. The baffle plate 202 prevents grass from tangling, and the grass-chopping blade 201 cuts the material, further reducing the possibility of grass tangling on the blade cylinder 101 and the mounting base 103.

[0029] The L-shaped protrusion 203 is disposed on the baffle plate 202 and located at one end of the baffle plate 202; the L-shaped protrusion 203 extends outward along the axial direction of the cutter barrel 101, and the L-shaped protrusion 203 has the same function as the anti-tangling plate 112 in the first embodiment, which can prevent grass from tangling at the connection between the cutter barrel 101 and the power shaft.

[0030] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
