Abstract
Description
Technical Field
[0001] This utility model relates to the field of grass shredders, and in particular to a deep-plowing double-edged grass shredder. Background Technology
[0002] Mini tillers are powered by small diesel or gasoline engines and are characterized by their light weight, small size, and simple structure. They are widely applicable to dry land, paddy fields, orchards, and other areas in plains, mountains, and hills. Mini tillers can move freely in the fields, making them convenient for users to use and store. They eliminate the problem of large agricultural machinery being unable to enter mountainous fields, making them the best alternative to oxen for farmers.
[0003] The blade holder of the mini tiller is equipped with blades for breaking soil and chopping grass. The blade beam of the blade holder has multiple cross-arranged blade slots, usually 7 or 9 blades. The blades are then fixed in the blade slots. The blades are just in the most common straight line shape. The above blade structure has the following problems: weeds in the gaps between the blades are very easy to get tangled on the blades or blade beam. If too much weeds get tangled, it will affect the operation of the deep tiller. Utility Model Content
[0004] The purpose of this utility model is to provide a deep tillage double-edged grass shredder, which can better cut and crush weeds when breaking the soil, reduce weed entanglement, and help ensure the stable operation of the deep tillage machine.
[0005] To achieve the above objectives, this utility model provides a deep-plowing double-edged grass shredder, including a blade mounting shaft, on which multiple left blade holders and right blade holders are provided. A left grass shredder blade is mounted on the left blade holder via a connector, and a right grass shredder blade is mounted on the right blade holder via a connector. The left and right grass-shredding blades are respectively provided with a soil-loosening and grass-shredding curved blade, a longitudinal grass-shredding blade, and a transverse grass-shredding blade.
[0006] The left and right tool holders are each provided with a mating cutting edge, and the mating cutting edge is symmetrically arranged on the left and right tool holders.
[0007] The connector adopts a T-shaped screw and nut structure.
[0008] The connector may also be a rivet structure.
[0009] The left and right grass-shredding blades are each provided with through mounting holes, and both are integral structures.
[0010] This utility model discloses a deep tillage double-bladed grass shredder. During installation, the blades are installed by cooperating with the drive shaft. Then, the drive shaft is driven to rotate by the drive mechanism, which in turn drives the left and right grass shredder blades. The soil-loosening and grass-shredding curved blades on the left and right grass shredder blades can cut weeds while loosening the soil. Furthermore, the longitudinal and transverse grass shredder blades continue to cut as they rotate, thereby enabling better cutting of weeds when breaking the soil, reducing weed entanglement, and thus ensuring the stable operation of the deep tillage machine.

Detailed Implementation
[0016] 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.
[0017] like Figures 1 to 3 As shown, where Figure 1 This is a schematic diagram of the overall structure of the Deep Cultivation Double-Edged Grass Cutter. Figure 2 This is a structural diagram of the curved blade used for loosening soil and cutting grass. Figure 3This is a schematic diagram of the right blade holder. This utility model provides a deep-tillage double-blade grass-chopping blade: it includes a blade shaft 101, a left blade holder 102, a right blade holder 103, a left grass-chopping blade 105, and a right grass-chopping blade 106. The left grass-chopping blade 105 and the right grass-chopping blade 106 are respectively provided with a soil-loosening and grass-chopping curved blade section 107, a longitudinal grass-chopping blade section 108, and a transverse grass-chopping blade section 109. This design allows for better cutting and pulverizing of weeds during soil breaking, reducing weed entanglement and ensuring stable operation of the deep tillage machine. It is understood that this design helps ensure the stable operation of the deep tillage machine.
[0018] In this embodiment, the mounting cutter shaft 101 is hexagonal, hollow inside, and has a through hole. During installation, it is slidably fitted onto the outside of the hexagonal end of the drive shaft of the deep tiller, and finally fixed with multiple bolts. Simultaneously, the structure of the hexagonal cavity inside the mounting cutter shaft 101 and the hexagonal end on the drive shaft allows for stable transmission.
[0019] The mounting shaft 101 is provided with multiple left blade holders 102 and right blade holders 103. A left grass-chopping blade 105 is mounted on the left blade holder 102 via a connector 104, and a right grass-chopping blade 106 is mounted on the right blade holder 103 via a connector 104. The left blade holders 102 and right blade holders 103 are arranged in a ring at uniform intervals and are directly welded to ensure stability. Each of the left blade holders 102 and right blade holders 103 has a blade groove, and a through hole is provided on the side wall of the blade groove to facilitate the installation and fixation of the left grass-chopping blade 105 and right grass-chopping blade 106 via the connector 104. After installation, the left grass-chopping blade 105 and right grass-chopping blade 106 can rotate when the mounting shaft 101 rotates, thereby achieving soil breaking and grass chopping.
[0020] The left and right grass-chopping blades 105 and 106 are respectively provided with a soil-loosening and grass-chopping curved blade section 107, a longitudinal grass-chopping blade section 108, and a transverse grass-chopping blade section 109. Compared with the straight blade structure of the prior art, the curved blade section 107 serves as a soil-breaking structure, and the blade on the curved section can cut and crush weeds when rotating. Furthermore, the longitudinal and transverse grass-chopping blade sections 108 and 109 assist in breaking the soil when rotating, and the blades on the longitudinal and transverse grass-chopping blade sections 108 and 109 further chop the grass when rotating.
[0021] Secondly, each of the multiple left blade holders 102 and right blade holders 103 is provided with a mating blade portion 110, which is symmetrically arranged on the left blade holders 102 and right blade holders 103. The mating blade portion 110 rotates with the left blade holders 102 and right blade holders 103, and is integrally set on the left blade holders 102 and right blade holders 103 to ensure strength and stability, thereby further forming a grass-shredding structure.
[0022] Then, the connector 104 adopts a T-shaped screw and nut structure. When the connector 104 adopts a T-shaped screw and nut structure, the left grass shredder 105 or the right grass shredder 106 is first inserted into the mounting groove of the left blade holder 102 or the right blade holder 103, respectively, then the T-shaped screw is inserted, and finally the nut is installed. This structure facilitates the quick replacement of the left grass shredder 105 or the right grass shredder 106. If the left grass shredder 105 or the right grass shredder 106 in the corresponding position is damaged in the future, it can be replaced individually, which helps to reduce the cost of use.
[0023] Furthermore, the connector 104 can also adopt a rivet structure. When the connector 104 adopts a rivet structure, the left grass shredder 105 or the right grass shredder 106 is not affected by the loosening of the nut after installation, the working stability of the left grass shredder 105 or the right grass shredder 106 is better, and the left grass shredder 105 or the right grass shredder 106 can be replaced after grinding off the rivet head.
[0024] Finally, the left grass shredder 105 and the right grass shredder 106 are each provided with a through mounting hole 111, and both are integral structures. The mounting hole 111 facilitates the left grass shredder 105 or the right grass shredder 106 to be fixed to the left blade holder 102 or the right blade holder 103 respectively with the connector 104. The diameter of the mounting hole 111 is consistent with the outer diameter of the T-screw or the outer diameter of the rivet, which facilitates sliding installation and can reduce the shaking of the left grass shredder 105 and the right grass shredder 106.
[0025] When using this invention to better cut and shred weeds during soil breaking, reducing weed entanglement and ensuring stable operation of the deep tillage machine, the blades are installed via the mounting blade shaft 101 and the drive shaft. Then, the drive shaft, driven by the deep tillage machine's drive mechanism, rotates, causing the mounting blade shaft 101 to rotate, which in turn drives the left and right grass-shredding blades 105 and 106. The loosening and grass-shredding curved blades 107 on the left and right grass-shredding blades 105 and 106 can cut weeds during soil loosening. Furthermore, the longitudinal grass-shredding blades 108 and the transverse... As the grass-chopping blade 109 rotates, it continues to cut and engage. Simultaneously, the longitudinal grass-chopping blade 108 and the transverse grass-chopping blade 109 cooperate to form an auxiliary double-edged structure. The cooperating blade 110 rotates with the left blade holder 102 and the right blade holder 103 and is integrally set on the left blade holder 102 and the right blade holder 103. During rotation, it can further form a grass-chopping and soil-breaking structure, thereby enabling better cutting of weeds during soil breaking, reducing weed entanglement, and thus better cutting and crushing of weeds during soil breaking, reducing weed entanglement, which is conducive to ensuring the stable operation of the deep tillage machine.
[0026] 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.
