Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a crushing device with adjustable spacing. Background Technology

[0002] In agricultural field operations, garden maintenance, and straw processing, crushing equipment is the core equipment for loosening soil and crushing weeds and crop straw. Its performance directly affects operational efficiency, soil improvement effects, and subsequent planting processes.

[0003] Currently, most equipment uses rigid welded or integral cast blade rollers, with fixed and non-adjustable rotary tillage blade mounting positions. This results in insufficient equipment applicability, and the working depth and lateral distribution density cannot be flexibly adjusted according to specific working conditions such as soil hardness, straw thickness, and moisture content. Consequently, when facing differentiated operating needs, problems such as poor crushing effect, excessive power consumption, or the need for multiple repetitive operations often occur. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable spacing crushing device, which solves the problem that the fixed and non-adjustable spacing of the cutter roller assembly in the prior art leads to poor adaptability and poor working effect of the equipment, which cannot meet different operating requirements.

[0005] To achieve the above objectives, this utility model provides an adjustable-gap crushing device, including a cutter barrel and an adjustment component. The adjustment component includes a single-hole mounting base, a rotary tiller blade, a grass-chopping seat, a three-hole mounting base, a fastening component, and an installation component.

[0019] 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.

[0020] First embodiment: Please see Figures 1 to 3 ,in Figure 1 This is a schematic diagram of the overall structure of an adjustable-gap crushing device. Figure 2 This is a schematic diagram of the overall structure of an adjustable-gap crushing device. Figure 3 This is a structural diagram of the installation components.

[0021] This utility model provides an adjustable spacing crushing device, including a cutter barrel 101 and an adjusting component 102. The adjusting component 102 includes a single-hole mounting base 103, a rotary tiller blade 104, a grass-chopping seat 105, a three-hole mounting base 106, a fastening component 107, and a mounting component 108. The fastening component 107 includes a bolt 109 and a nut 110. The grass-chopping seat 105 includes a base body 111, a radial blade 112, and an axial blade 113. The rotary tiller blade 104 has a first through hole 114, and the base body 111 has... The second through hole 115, the single-hole mounting base 103 has a positioning groove 116, the mounting member 108 drives the single-hole mounting base 103 to move on the blade cylinder 101, thereby driving the corresponding rotary tiller blade 104 and the grass shredder 105 to move, thereby adjusting the distance between the rotary tiller blade 104 and the grass shredder 105. It can be understood that the above solution can be used to facilitate the adjustment of the distance between the rotary tiller blade 104 and the grass shredder 105, and can also be used to improve the grass shredding effect.

[0022] In this specific embodiment, the cutter barrel 101 has a regular hexagonal cross-section and can be installed between two end plates of the frame of agricultural equipment (not shown in the figure), and can be driven by the power unit of the agricultural equipment to achieve rotational operation.

[0023] The mounting component 108 is disposed on the blade cylinder 101. The single-hole mounting base 103 is connected to the blade cylinder 101 via the mounting component 108. The rotary tiller blade 104 is connected to and disposed on the single-hole mounting base 103. The grass shredder 105 is connected to and disposed on the single-hole mounting base 103. The fastening component 107 is disposed on the single-hole mounting base 103 and fixes the rotary tiller blade 104 and the grass shredder 105 to the single-hole mounting base 103. The three-hole mounting base 106 is connected to and sleeved on the blade cylinder 101. Multiple single-hole mounting bases 103 are provided, each with a slot for connecting the rotary tiller blade 104 and the mounting base. Insert the single-hole mounting base 103 into the blade cylinder 101. Two three-hole mounting bases 106 are provided, with each three-hole mounting base 106 having three slots, capable of simultaneously mounting three sets of rotary tillers 104 and grass shredders 105. The three sets of rotary tillers 104 and grass shredders 105 on the three-hole mounting base 106 are locked together by three sets of fastening components 107. The installation method of the rotary tillers 104 and grass shredders 105 on the three-hole mounting base 106 is the same as that of the single-hole mounting base 103, and will not be described in detail here. The mounting component 108 is used to mount the single-hole mounting base 103 onto the blade cylinder 101. The end of the rotary tiller 104 is provided with a curved part, which can enhance the soil shredding ability of the rotary tiller 104.

[0024] In use, the rotary tiller blades 104 and the straw shredder 105 are respectively installed on the single-hole mounting base 103 and the three-hole mounting base 106, and the rotary tiller blades 104 and the straw shredder 105 on the single-hole mounting base 103 are locked by the fastening member 107. The agricultural machinery drives the blade cylinder 101 to rotate, which in turn drives the single-hole mounting base 103 and the three-hole mounting base 106 to rotate, thereby driving the multiple rotary tiller blades 104 and straw shredders 105 to rotate, performing rotary tillage and straw shredding operations. When it is necessary to adjust the spacing of the rotary tiller blades 104, the [unclear text - possibly a component or component] is disassembled. The rotary tiller 104 and the grass shredder 105 are installed, then the mounting member 108 is unlocked, and the position of the mounting member 108 on the blade cylinder 101 is adjusted, thereby moving the single-hole mounting seat 103 on the blade cylinder 101. After the position of the single-hole mounting seat 103 is adjusted to the correct position, the mounting member 108 is locked onto the blade cylinder 101. Finally, the rotary tiller 104 and the grass shredder 105 are reinstalled on the single-hole mounting seat 103, thereby flexibly adjusting the distance between the rotary tiller 104 and the grass shredder 105 to meet different operational needs.

[0025] Secondly, the mounting component 108 includes a sliding seat 117 and an adjusting bolt 118. The sliding seat 117 is slidably connected to the blade cylinder 101 and fixedly connected to the single-hole mounting base 103, and is sleeved on the blade cylinder 101. The adjusting bolt 118 is threadedly connected to the sliding seat 117 and passes through the sliding seat 117. The blade cylinder 101 has bolt holes 119 that pass through the blade cylinder 101 and cooperate with the adjusting bolt 118. Multiple bolt holes 119 are provided and evenly distributed on the blade cylinder 101. When it is necessary to adjust the position of the rotary tiller 104 and the grass shredder 105, the adjusting bolt 118 is unscrewed. The adjusting bolt 118 is moved out of the bolt hole 119, at which point the sliding seat 117 can slide on the blade cylinder 101, thereby allowing the position of the single-hole mounting seat 103 to be adjusted. After the position of the single-hole mounting seat 103 is adjusted to the correct position, the position of the sliding seat 117 is finely adjusted so that the adjusting bolt 118 is aligned with one of the bolt holes 119. Then, the adjusting bolt 118 is tightened so that it extends into the bolt hole 119, thereby fixing the sliding seat 117 and the single-hole mounting seat 103 on the blade cylinder 101, achieving the purpose of adjusting the position of the rotary tiller 104 and the grass shredder 105.

[0026] Meanwhile, the bolt 109 is connected to the single-hole mounting base 103 and passes through the rotary tiller 104 and the grass shredder 105; the nut 110 is threadedly connected to the bolt 109 and is sleeved on the bolt 109.

[0027] Then, the base 111 is connected to the single-hole mounting base 103; the radial blade 112 is fixedly connected to the base 111 and disposed on the base 111; the axial blade 113 is fixedly connected to the base 111 and disposed on the base 111; the base 111, the radial blade 112 and the axial blade 113 are integrally formed, the radial blade 112 extends outward along the radial direction of the blade cylinder 101, that is, the length direction of the blade is perpendicular to the axis of the blade cylinder 101, the axial blade 113 extends outward along the axial direction of the blade cylinder 101, the axial blade 113 is perpendicular to the radial blade 112, when the straw shredder 105 rotates, the radial blade 112 cuts the straw and weeds turned up by the loosening sheet laterally; the axial blade 113 cuts the straw longitudinally, further refining the straw particle size.

[0028] In addition, the rotary tiller 104 has a first through hole 114, which penetrates the rotary tiller 104 and engages with the bolt 109; the base 111 has a second through hole 115, which penetrates the base 111 and engages with the bolt 109.

[0029] Then, the positioning groove 116 is provided on one side of the single-hole mounting base 103, and the positioning groove 116 cooperates with the bolt 109.

[0030] When installing the rotary tiller 104 and the grass shredder 105, insert the rotary tiller 104 and the grass shredder 105 into the slots on the single-hole mounting base 103, aligning the first through hole 114 and the second through hole 115. Then, pass the bolt 109 through the first through hole 114 and the second through hole 115, and let the head of the bolt 109 extend into the positioning groove 116. Then, put the nut 110 on the bolt 109 and tighten it, thus fixing the rotary tiller 104 and the grass shredder 105 onto the single-hole mounting base 103. At the same time, since the head of the bolt 109 is stuck in the positioning groove 116, the positioning groove 116 limits the bolt 109. Through the circumferential limiting effect of the positioning groove 116, the rotation tendency of the bolt 109 caused by the high-speed rotation vibration of the equipment is eliminated, preventing the bolt 109 from loosening.

[0031] Finally, the blade barrel 101 has a locking groove 120, which is disposed on the blade barrel 101 and engages with the rotary tiller 104 and the base 111. When the rotary tiller 104 and the grass shredder 105 are installed in place, the roots of the rotary tiller 104 and the grass shredder 105 extend into the locking groove 120. At this time, the locking groove 120 not only limits the rotary tiller 104 and the grass shredder 105, improving their stability, but also enhances the stability of the mounting base on the blade barrel 101.

[0032] When using the adjustable spacing shredder of this embodiment, the spacing between the rotary tiller blades 104 and the grass shredder 105 is determined according to agronomic requirements. If adjustment is required, the adjusting bolt 118 is loosened to allow the sliding seat 117 to slide axially on the blade cylinder 101, thereby moving the single-hole mounting base 103. Then, the adjusting bolt 118 is aligned with the bolt hole 119 corresponding to the position and tightened to complete the positioning and locking. Finally, the rotary tiller blades 104 and the grass shredder 105 are inserted into the insertion holes on the single-hole mounting base 103, so that the roots of the rotary tiller blades 104 and the grass shredder 105 are inserted into the snap-fit ​​groove 120. The rotary tiller blades 104 and the grass shredder 105 are locked onto the single-hole mounting base 103 by the bolt 109 and the nut 110, thereby achieving the adjustment of the spacing between the rotary tiller blades 104 and the grass shredder 105 to adapt to different operational purposes.

[0033] Second embodiment: Based on the first embodiment, please refer to Figure 4 , Figure 4 This is a schematic diagram of the installation structure of the stabilizing disk in the second embodiment. The adjustable spacing crushing device in this embodiment also includes a stabilizing disk 201, which includes a toothed disk 202 and an anti-tangling plate 203.

[0034] In this specific embodiment, the stabilizing disk 201 is fixedly connected to the three-hole mounting base 106 and is located on one side of the three-hole mounting base 106.

[0035] The toothed disc 202 is fixedly connected to the cutter cylinder 101 and is located on one side of the cutter cylinder 101; the anti-tangling plate 203 is fixedly connected to the toothed disc 202 and is located on one side of the toothed disc 202.

[0036] When using the adjustable spacing crushing equipment of this embodiment, one stabilizing disc 201 is provided and installed on the outside of one of the three-hole mounting bases 106. The stabilizing disc rotates synchronously with the cutter cylinder 101, providing longitudinal support for the entire cutter roller assembly, effectively suppressing the radial runout and sway of the whole machine caused by uneven soil resistance during operation, and enhancing the stability of the equipment operation; the anti-winding plate 203 rotates synchronously with the toothed disc 202, and its plate structure can effectively block and cut straw and weeds that attempt to wind into the bearing seat of the cutter cylinder 101 or the inside of the frame.
