Description

Technical Field

[0001] This invention relates to the field of desertification control technology, and in particular to a uniform grass distribution device for a grass checkerboard sand barrier machine. Background Technology

[0002] Land desertification leads to a decrease in grain yields from arable land, and wind and sand movement has a serious impact on farmland, transportation, and residential areas. Straw checkerboard sand barriers, with their advantages of simple installation, low cost, and significant effects, play an indispensable role in the ecological restoration of sandy land and the protection of key construction projects.

[0003] In existing technologies, the grass checkerboard sand barrier machine produces loose grass with gaps during the laying process, which cannot achieve uniform distribution of the loose grass. This results in gaps in the laid grass checkerboard, which seriously weakens its effect of preventing wind and fixing sand. Summary of the Invention

[0004] The purpose of this invention is to overcome the aforementioned problems and provide a uniform straw output device for a straw checkerboard sand barrier machine. Through mechanical movement, the entanglement between the straw is broken, and the straw is transformed from a "pile" into a "bundle". As the straw moves backward at an accelerated speed with the teeth, the straw on the conveyor belt will aggregate into a whole when it encounters the bundle. Under mechanical action, the bundle becomes denser, eliminating the gaps that occur when the straw is unbundled and transported, thus achieving uniform laying.

[0005] The grass uniform output device of the grass checkerboard sand barrier machine is characterized in that: the device includes a spreading and conveying device and a grass gathering device; the grass gathering device is located above the spreading and conveying device, which is responsible for spreading the grass thin and conveying it backward; the grass gathering device is used to separate the tangled grass, gather the grass on the conveyor belt together, eliminate the gaps that occur when the grass is unbundled and conveyed, thereby achieving uniform output of the grass.

[0007] Furthermore, a thinning roller is fixedly mounted on the third drive shaft. The thinning roller has four blades distributed circumferentially, and the lowest position of the blades of the thinning roller is 3 cm away from the synchronous belt during the movement.

[0008] Preferably, the hay gathering device includes a lateral movement component, a crank-slider mechanism, a hay-dividing shaft, a first counterweight wheel, a second counterweight wheel, a first bevel gear, a second bevel gear, a hay-dividing reduction motor, a hay-dividing shaft fixing seat, and a chuck. The hay-dividing shaft is arranged perpendicular to the center line above the hay conveying synchronous belt, with one end connected to the hay-dividing reduction motor and the other end rotatably connected to the hay-dividing shaft fixing seat via a bearing. The first and second counterweight wheels are symmetrically arranged on the hay-dividing shaft along the center line. The first bevel gear is fixedly installed on the hay-dividing shaft and located inside the second counterweight wheel. The lateral movement component drives the chuck to move laterally, and the crank-slider mechanism drives the chuck to move longitudinally. The lateral movement component and the crank-slider mechanism achieve synchronous movement through the transmission between the first and second bevel gears.

[0009] Preferably, the crank-slider mechanism includes an eccentric wheel, a first connecting rod, and a second connecting rod; two sets of crank-slider mechanisms are symmetrically arranged on the outside of the counterweight wheel along the center line, the eccentric wheel is fixed on the grass-distributing shaft and driven by the grass-distributing reduction motor, one end of the first connecting rod is hinged to the eccentric wheel, and the other end is hinged to one end of the second connecting rod, the second connecting rod passes through a rectangular through hole provided on the slider guide rail, and the other end is fixedly connected to the pick teeth.

[0010] Preferably, the lateral movement component includes rectangular steel, a guide rail fixing seat, a central fixing seat, a slider, a central turntable, a lateral movement guide rail, and a slider guide rail; two rectangular steels are arranged perpendicularly to the center line between the grass conveying synchronous belt and the grass separating shaft, and their two ends are fixedly connected to the vehicle body; the slider guide rail has two circular through holes on both sides that mate with the lateral movement guide rail, and two rectangular through holes adapted to the second connecting rod and a rectangular groove adapted to the slider inside; the lateral movement guide rail passes through the circular through holes and is slidably connected to the slider guide rail, and its two ends are fixedly connected to the guide rail fixing seat, which is fixed to the rectangular steel; the central fixing seat is fixed to the rectangular steel at its lower part, and has a circular hole in the center with a bearing installed; a long shaft is fixedly fixed to the center of one side of the central turntable, and a short shaft is eccentrically fixed to the other side, the middle section of the long shaft is rotatably connected to the central fixing seat through a bearing, and a second bevel gear is fixed to the end of the long shaft, and the end of the short shaft is fixedly connected to the slider.

[0011] The beneficial effects of this invention are:

[0012] This invention proposes an elliptical trajectory straw gathering device. This device has a long lateral movement trajectory, which can effectively separate tangled loose straw and transform the loose straw from a concentrated "pile" state to a dispersed "bundle" state. As the straw is accelerated backward by the rake teeth, the straw on the conveyor belt will aggregate into a whole when it encounters the device. Under mechanical action, the straw becomes denser, eliminating gaps that occur during the unbundling and conveying of loose straw, and achieving uniform laying.

[0013] The teeth in the grass gathering device remain perpendicular to the ground during operation, reducing disturbance to the loose grass during the separation process and minimizing tangling at the output end. Attached Figure Description

[0022] like Figures 1 to 5 As shown, a preferred embodiment of the grass checkerboard sand barrier machine provided by the present invention includes a grass spreading and conveying device 1 and a grass gathering device 2.

[0023] The thinning and conveying device 1 of the present invention includes a first drive shaft 101, a second drive shaft 102, a third drive shaft 103, a driving pulley 104, a driven pulley 105, a grass conveying synchronous belt 106, a transmission synchronous belt 107, a thinning roller 108, a conveying reduction motor 109, and a conveying fixed seat 110; one end of the first drive shaft 101 is connected to the conveying reduction motor 109, and the other end is rotatably connected to the conveying fixed seat 110 via a bearing; the second drive shaft 102 and the third drive shaft 103 are arranged perpendicular to the center line. The side end is rotatably connected to the conveying fixed seat 110 via a bearing; the first drive shaft 101 and the second drive shaft 102 are driven by nine grass conveying synchronous belts 106 with a width of 6cm; the second drive shaft 102 and the third drive shaft 103 are driven by a driving pulley 104, a driven pulley 105, and a transmission synchronous belt 107 mounted on the pulley; the spreading roller 108 is fixed on the third drive shaft 103, and during its movement, the lowest position of the blade of the spreading roller 108 is 3cm away from the synchronous belt.

[0024] The hay gathering device 2 of the present invention includes a lateral movement component 201, a crank-slider mechanism 202, a hay-dividing shaft 203, a first counterweight wheel 204, a second counterweight wheel 205, a first bevel gear 206, a second bevel gear 207, a hay-dividing reduction motor 208, a pick 209, a hay-dividing shaft fixing seat 210, and a guide rail fixing seat 211. The lateral movement component 201 drives the pick 209 to move laterally, and the crank-slider mechanism 202 drives the pick 209 to move longitudinally. The lateral movement component 201 and the crank-slider mechanism 202 are connected by the first bevel gear. 206 moves synchronously with the second bevel gear 207. The grass-distributing shaft 203 is arranged perpendicularly to the center line above the grass-conveying synchronous belt 106. One end is connected to the grass-distributing reduction motor 208, and the other end is rotatably connected to the grass-distributing shaft fixing seat 210 through a bearing. The first counterweight wheel 204 and the second counterweight wheel 205 are symmetrically fixed on the grass-distributing shaft 203 along the center line. The second counterweight wheel 205 is located between the first bevel gear 206 and the right crank-slider mechanism 202. The center of mass of the two counterweight wheels is located above the grass-distributing shaft 203, and the initial position of the line connecting the two counterweight wheels and the center is perpendicular to the ground.

[0025] The lateral movement component 201 consists of rectangular steel 2011, a central fixed seat 2012, a slider 2013, a central turntable 2014, a lateral movement guide rail 2015, and a slider guide rail 2016. Two rectangular steel 2011s are arranged perpendicularly to the center line between the grass conveying synchronous belt 106 and the grass separating shaft 203, with their bottom surfaces 21cm vertically from the grass conveying synchronous belt 106. Both ends are fixed to the inner side of the vehicle body. The slider guide rail 2016 has two circular through holes on both sides that mate with the lateral movement guide rail 2015. Inside, it has two rectangular through holes adapted to the second connecting rod 2023 and a rectangular groove adapted to the slider. The rectangular groove is 30cm long. The transverse motion guide rail 2015 passes through a circular through hole and is slidably connected to the slider guide rail 2016. Both ends of each transverse motion guide rail 2015 are fixedly connected to the guide rail fixing seat 211 by interference fit. The guide rail fixing seat 211 is fixed to the rectangular steel 2011 by four detachable bolts. The center fixing seat 2012 is fixed to the rectangular steel 2011 at the bottom and has a circular hole in the center with a bearing. The center turntable 2014 has a long shaft fixed to the center on one side and a short shaft fixed eccentrically on the other side with an eccentricity of 10cm. The middle section of the long shaft is rotatably connected to the center fixing seat through a bearing, and the end is fixed with a second bevel gear 207. The end of the short shaft is fixedly connected to the slider 2013.

[0026] The device has two sets of crank-slider mechanisms 202. Each set of crank-slider mechanisms 202 consists of an eccentric wheel 2021, a first connecting rod 2022, and a second connecting rod 2023. The two eccentric wheels 2021 are symmetrically fixed on the grass-distributing shaft 203 along the center line. One end of the first connecting rod 2022 is hinged to the eccentric wheel 2021, and the other end is hinged to the second connecting rod 2023. The second connecting rod 2023 is fixedly connected to the picker tooth 209 through the through hole of the slider guide rail 2016, so as to drive the picker tooth 209 to move longitudinally. The picker tooth 209 is provided with eight equidistant teeth, which are staggered with the grass conveying synchronous belt 106.

[0027] In operation, the present invention first activates the conveying reduction motor 109 and the grass-distributing reduction motor 208 via the PLC controller. This causes the first drive shaft 101 and the second drive shaft 102 to rotate synchronously via nine grass-conveying synchronous belts 106, which then convey the loose grass falling on the grass-conveying synchronous belts 106 forward. The second drive shaft 102 and the third drive shaft 103 rotate synchronously via pulleys and a transmission synchronous belt 107. The spreading roller 108 rotates synchronously with the third drive shaft 103 and uses its fixed blades to spread out any excessively high loose grass. The grass-distributing shaft 203 drives the crank-slider mechanism 202, which in turn pushes the picker teeth 209 to move longitudinally. The picker teeth 209 pass through the gaps in the grass-conveying synchronous belts 106 to perform their work. Meanwhile, the central turntable 2014 rotates synchronously with the grass-separating shaft 203 via the bevel gear 206. The central turntable 2014 drives the slider 2013 and its guide rail 2016 to move laterally. The slider guide rail 2016 further drives the raking teeth 209 fixed on the second connecting rod 2023 to move laterally, thereby causing the raking teeth 209 to form an elliptical trajectory at the end. Through this movement, the loose grass is separated from the piled state into bundles, eliminating the gaps that occur when the loose grass is unbundled and conveyed, thus achieving uniform output of loose grass.

[0028] Any descriptions not covered in the above specific embodiments of the present invention are known technologies in the field and can be implemented with reference to such known technologies.

[0029] Based on the preferred embodiments of the present invention described above, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
