Description

Technical Field

[0001] This utility model belongs to the field of new energy agricultural machinery technology, and relates to an electric rotary tiller, particularly an electric rotary tiller suitable for small new energy agricultural machinery. Background Technology

[0002] A rotary tiller is a tillage machine that works in conjunction with agricultural machinery to perform tilling and harrowing operations. It is widely used due to its strong soil-breaking ability and the ability to create a flat surface after tilling. During operation, the rotary tiller's blade shaft drives the blades to rotate, tilling the land and simultaneously chopping up stubble buried below the surface, facilitating seeder operation and providing a good seedbed for later sowing.

[0003] Existing traditional fuel-fired rotary tillers have high carbon emissions, do not meet environmental standards, and have high operating costs. In hilly and mountainous areas, where arable land accounts for a large proportion, traditional fuel-fired agricultural machinery is difficult to adapt to the terrain. New energy agricultural machinery is small in size and has low operating costs.

[0004] Existing rotary tillers are generally paired with fuel-powered agricultural machinery, which are large in size and cannot meet the needs of small plots. In addition, the shaft of traditional rotary tillers is prone to getting tangled with straw and weeds, which is inconvenient to clean and requires a lot of manual labor.

[0005] Therefore, we propose an electric rotary tiller suitable for small new energy agricultural machinery. It can be adapted to various sizes of new energy agricultural machinery, and can perform integrated soil tillage and crushing operations. It can perform secondary crushing of tilled soil clods, refine the soil structure, and collect uncrushed weeds to ensure the quality of rotary tillage. It can also remove tangled straw and weeds, reduce manual labor intensity, and improve work efficiency. Utility Model Content

[0006] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing an electric rotary tiller suitable for small new energy agricultural machinery. The technical problem to be solved by this utility model is: how to achieve high-quality and efficient integrated rotary tillage and crushing of soil through an electric rotary tiller, and to quickly remove tangled weeds and improve work efficiency.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] An electric rotary tiller suitable for small new energy agricultural machinery includes a plow frame mechanism. An adjustment mechanism is hinged to the front side of the plow frame mechanism and is hinged to the upper end of the plow frame mechanism. A mud-crushing rake is provided on the adjustment mechanism. A plow shaft mechanism is rotatably provided inside the lower part of the plow frame mechanism. An anti-winding mechanism is fixed on the plow shaft mechanism. Several rotary tiller mechanisms are provided on the anti-winding mechanism at equal intervals. The rotary tiller mechanisms all abut against the plow shaft mechanism. A water-cooled drive motor is fixed to the upper end of the plow frame mechanism. The output shaft of the water-cooled drive motor is connected to the plow shaft mechanism through a sprocket pair transmission.

[0009] The working principle of this utility model is as follows: During operation, the electric rotary tiller is suspended on a small agricultural machine via a plow frame mechanism. After the water-cooled drive motor's water inlet pipe is installed, the small agricultural machine is driven to perform rotary tillage. The output shaft of the water-cooled drive motor drives the plow shaft mechanism through a sprocket pair. The plow shaft mechanism drives the anti-winding mechanism and several rotary tillage mechanisms. These rotary tillage mechanisms achieve integrated soil turning and breaking operations through rotation. The water-cooled drive motor ensures that the motor temperature can be controlled during long-term operation, adapting to the needs of high-intensity farming. During rotary tillage, the regulating mechanism is controlled. The rotary tillage mechanism drives the movement of the soil clods. During rotary tillage, the soil clods are broken up a second time, refining the soil structure. The soil clods are also collected by the soil clods to prevent them from affecting the quality of rotary tillage. If straw or weeds become entangled on the rotary tillage mechanism and affect the rotary tillage, the machine is stopped and the anti-entanglement mechanism is manually turned. The anti-entanglement mechanism drives the rotary tillage mechanism to expand. At the same time as the expansion, the anti-entanglement mechanism cuts and removes the entangled straw and weeds, reducing the intensity of manual labor.

[0010] The plow frame mechanism includes a rotary plow frame and a chain guard. Two symmetrically arranged suspension frames are fixed at the middle of the rear side of the rotary plow frame. A motor guard is fixed at the upper left side of the rotary plow frame. The two ends of the chain guard are fixed to the left side of the rotary plow frame and the left side of the motor guard, respectively. Anti-winding bearing seats are provided on both sides of the lower interior of the rotary plow frame, and the two anti-winding bearing seats are symmetrically arranged. Two symmetrically arranged hinge seats are fixed at the front side of the rotary plow frame.

[0011] With the above structure, the chain guard is used to reduce the risk of chain detachment, the two suspension brackets are used to suspend the electric rotary tiller on the small agricultural machine, the motor guard facilitates the installation of water cooling pipes and prevents splashes from damaging the motor, and the hinge mount is used to install the adjustment mechanism.

[0012] The adjustment mechanism includes an electric push rod and an adjustment baffle. The adjustment baffle is hinged to the inner top front side of the rotary tiller frame. Two hinge seats 2 are fixed on the adjustment baffle, which are arranged symmetrically on the left and right. The positions of the hinge seats 2 and the corresponding hinge seats 1 are opposite. A connecting shaft is hinged between the hinge seats 2 and the corresponding hinge seats 1. The hinge seats 1 are hinged to the middle position of the connecting shaft. The electric push rod is hinged to the upper end of the rotary tiller frame. An adjustment rod is rotatably provided on the telescopic end of the electric push rod. Connectors are fixed at both ends of the adjustment rod. The other end of the connector is fixedly connected to the end of the corresponding connecting shaft.

[0013] With the above structure, the telescopic end of the electric push rod drives the adjusting rod to move. The adjusting rod drives the corresponding connecting shaft to move synchronously through two connectors. The synchronous movement of the two connecting shafts drives the adjusting baffle to move, and the adjusting baffle drives the mud rake to move.

[0014] The mud-crushing rake includes a mud-crushing plate, which is detachably mounted on the adjusting baffle. The mud-crushing plate is located on the front side of the hinge seat two, and several equally spaced arc-shaped rake teeth are fixed on the front side of the mud-crushing plate.

[0015] With the above structure, during rotary tillage, several arc-shaped rake teeth are used to break up the soil clods after tillage, refine the soil structure, and collect the unbroken grass stems and straw, ensuring the quality of rotary tillage.

[0016] The plow shaft mechanism includes a hollow shaft, with rotating shafts on both sides of the hollow shaft. The two rotating shafts are symmetrically arranged and fixed inside the inner ring of the anti-winding bearing seat. One of the rotating shafts has an expansion shaft hole, and a baffle is fitted on each rotating shaft.

[0017] With the above structure, the output shaft of the water-cooled drive motor drives the rotating shaft on the left side through the sprocket pair, thereby driving the baffle and the hollow shaft to move. The baffle is used to block mud, and the hollow shaft facilitates the movement of the anti-winding mechanism.

[0018] The anti-winding mechanism includes two symmetrically arranged inner expansion components with identical shapes and structures. The two inner expansion components are located at opposite ends of the hollow shaft, and a drive shaft rotatably connects them. The drive shaft passes through the hollow shaft and the two inner expansion components, with drive gears fixed at both ends and a driven gear fixed in the middle. Five circumferentially distributed cutting blades are arranged on the outer sides of the two inner expansion components, each blade abutting against the hollow shaft. Each inner expansion component includes an expansion slide, which is fixed to the end of the hollow shaft. A guide gear is rotatably mounted on each expansion slide, and the guide gears are aligned with corresponding drive gears. The gears mesh, and each guide gear has five circumferentially distributed guide grooves. One end of each guide groove is close to the center of the guide gear, and the other end is far from the center of the guide gear. Each expansion slide has five circumferentially distributed expansion grooves. Each expansion groove has a sliding rod that slides inside it. One end of each sliding rod is fixed with a guide rod. The position of each guide rod corresponds to the guide groove on the same side, and each guide rod slides in the corresponding guide groove. The other end of each sliding rod is fixed with an arc-shaped top plate. Each arc-shaped top plate has a mounting groove in the middle of its end. The cutting blade is fixed in the mounting groove of each of the two inner expansion components.

[0019] With the above structure, by inserting the end of the rocker arm into the expansion shaft hole, the end of the rocker arm can rotate within the expansion shaft hole. The end of the rocker arm also has a driving gear that can mesh with the driven gear. When the rocker arm is manually rotated, the rocker arm drives the driven gear to rotate through the driving gear at the end, thereby driving the transmission shaft to rotate. The transmission shaft drives two drive gears to rotate, and the two drive gears drive the guide gears at corresponding positions to move. When the guide gears move, they drive the guide rods at corresponding positions through the five guide grooves on them. The guide rods drive the arc-shaped top plates at corresponding positions, and the arc-shaped top plates drive the cutting blades at corresponding positions to move.

[0020] The rotary tillage mechanism includes five groups of equidistantly distributed expanding arc plates and five equidistantly distributed arc-shaped mud-blocking plates. Each group of expanding arc plates consists of two expanding arc plates, which are respectively fixed to two arc-shaped top plates at symmetrical positions of two inner expanding components. The two expanding arc plates are symmetrically distributed on both sides of the mounting groove. The inner side of the expanding arc plate abuts against the cutting blade, and the outer side of the expanding arc plate is flush with the side of the arc-shaped top plate. An arc-shaped mud-blocking plate is fixed below one of the expanding arc plates in each group of expanding arc plates. The arc-shaped mud-blocking plates are located between the arc-shaped top plates at symmetrical positions of two inner expanding components. The arc degree of the arc-shaped mud-blocking plate is equal to that of the arc degree of the arc-shaped top plate. The arc-shaped mud-blocking plates abut against the hollow shaft, and the two sides of the arc-shaped mud-blocking plates abut against two adjacent cutting blades respectively. Several plowshare seats are provided on the expanding arc plates. The positions of the several plowshare seats on each expanding arc plate are different, and plow blades are detachably provided on each plowshare seat.

[0021] With the above structure, during rotary tillage, the arc-shaped top plate drives the corresponding expansion arc plate to move, the expansion arc plate drives several plow teeth to move, the several plow teeth drive the corresponding plow blades to move, and the several plow blades rotate to carry out soil turning and crushing in one operation. At the same time, it crushes some straw and weeds, improving the quality of rotary tillage. The arc-shaped mud barrier is used to prevent soil from entering when cutting tangled weeds, ensuring a clean working environment.

[0022] Compared with existing technologies, this electric rotary tiller, suitable for small-scale new energy agricultural machinery, has the following advantages:

[0023] 1. This electric rotary tiller can be suspended on new energy agricultural machinery through the plow frame mechanism, making it compatible with various specifications of new energy agricultural machinery.

[0024] 2. The plow shaft mechanism is driven by a water-cooled drive motor, which in turn drives the anti-winding mechanism and several rotary tillage mechanisms to rotate, thereby achieving integrated soil tillage and crushing operations.

[0025] 3. The adjustment mechanism drives the mud-breaking rake to move, which penetrates into the soil to break up the tilled soil clods a second time, refine the soil structure, and collect the unbroken grass stems and straw, ensuring the quality of rotary tillage.

[0026] 4. By cooperating with the anti-winding mechanism, the plow shaft mechanism, and the rotary tiller mechanism, the anti-winding mechanism is manually driven by the plow shaft mechanism, which in turn drives several rotary tiller mechanisms to expand. Simultaneously, the anti-winding mechanism cuts the tangled straw and weeds, reducing manual labor intensity and improving work efficiency. Attached Figure Description

[0037] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0038] like Figures 1-9As shown, this electric rotary tiller, applicable to small new energy agricultural machinery, includes a plow frame mechanism 1. An adjustment mechanism 2 is hinged to the front side of the plow frame mechanism 1, and the adjustment mechanism 2 is hinged to the upper end of the plow frame mechanism 1. A mud-crushing rake 4 is provided on the adjustment mechanism 2. A plow shaft mechanism 22 is rotatably provided inside the lower part of the plow frame mechanism 1. An anti-winding mechanism 6 is fixed on the plow shaft mechanism 22. Several rotary tiller mechanisms 3 are provided on the anti-winding mechanism 6 at equal intervals. Several rotary tiller mechanisms 3 abut against the plow shaft mechanism 22. A water-cooled drive motor 5 is fixed to the upper end of the plow frame mechanism 1. The output shaft of the water-cooled drive motor 5 is connected to the plow shaft mechanism 22 through a sprocket pair transmission.

[0039] In this embodiment, during operation, the electric rotary tiller is suspended on a small agricultural machine via the plow frame mechanism 1. After the water inlet pipe of the water-cooled drive motor 5 is installed, the small agricultural machine is driven to perform rotary tillage. The output shaft of the water-cooled drive motor 5 drives the plow shaft mechanism 22 to move via the sprocket pair. The plow shaft mechanism 22 drives the anti-winding mechanism 6 and several rotary tillage mechanisms 3 to move. The several rotary tillage mechanisms 3 achieve integrated soil turning and crushing operations through rotation. The water-cooled drive motor 5 ensures that the motor temperature can be controlled during long-term operation, adapting to the needs of high-intensity farming. During rotary tillage, the control and adjustment mechanism 2 is used. The movement and adjustment mechanism 2 drives the mud-crushing rake 4 to move. During rotary tillage, the mud-crushing rake 4 further breaks up the soil clods after tillage, refines the soil structure, and collects uncrushed grass stems and straw to avoid affecting the quality of rotary tillage. If straw and weeds become entangled on several rotary tillage plow mechanisms 3 and affect rotary tillage, the machine stops, and the anti-entanglement mechanism 6 is manually driven to rotate. The anti-entanglement mechanism 6 drives several rotary tillage plow mechanisms 3 to expand. At the same time as expansion, the anti-entanglement mechanism 6 cuts and removes the entangled straw and weeds, reducing the intensity of manual labor.

[0040] The plow frame mechanism 1 includes a rotary plow frame 7 and a chain guard 10. Two symmetrically arranged suspension frames 8 are fixed at the middle of the rear side of the rotary plow frame 7. A motor guard 9 is fixed at the upper left side of the rotary plow frame 7.

[0042] The adjustment mechanism 2 includes an electric push rod 16 and an adjustment baffle 11. The adjustment baffle 11 is hinged to the inner top front side of the rotary tiller frame 7. Two hinge seats 2 are fixed on the adjustment baffle 11, which are symmetrically arranged on the left and right. The positions of the hinge seats 2 and the hinge seats 1 are corresponding to those of the hinge seats 1. A connecting shaft 15 is hinged between the hinge seats 2 and the corresponding hinge seats 1. The hinge seats 1 are hinged to the middle position of the connecting shaft 15.

[0043] In this embodiment, the telescopic end of the electric push rod 16 drives the adjusting rod 13 to move. The adjusting rod 13 drives the corresponding connecting shaft 15 to move synchronously through two connectors 14. The synchronous movement of the two connecting shafts 15 drives the adjusting baffle 11 to move, and the adjusting baffle 11 drives the mud rake 4 to move.

[0044] The mud-crushing rake 4 includes a mud-crushing plate 17, which is detachably mounted on the adjusting baffle 11. The mud-crushing plate 17 is located on the front side of the hinge seat 2, and a number of equally spaced arc-shaped rake teeth 18 are fixed on the front side of the mud-crushing plate 17.

[0045] In this embodiment, during rotary tillage, several arc-shaped harrow teeth 18 are used to break up the tilled soil clods a second time, refine the soil structure, and collect the unbroken grass stems and straw, ensuring the quality of rotary tillage.

[0046] The plow shaft mechanism 22 includes a hollow shaft 33, with rotating shafts 23 on both sides of the hollow shaft 33. The two rotating shafts 23 are symmetrically arranged and are fixed inside the inner ring of the anti-winding bearing seat 12. One of the rotating shafts 23 has an expansion shaft hole, and each rotating shaft 23 is fitted with a baffle 19.

[0047] In this embodiment, the output shaft of the water-cooled drive motor 5 drives the left rotating shaft 23 to move through the sprocket pair, thereby driving the baffle 19 and the hollow shaft 33 to move. The baffle 19 is used to block mud, and the hollow shaft 33 facilitates the movement of the anti-winding mechanism 6.

[0048] The anti-winding mechanism 6 includes two symmetrically arranged inner expansion components with identical shapes and structures. The two inner expansion components are located at opposite ends of the hollow shaft 33. A drive shaft 29 rotatably connects the two inner expansion components, passing through the hollow shaft 33 and the two inner expansion components. Drive gears 30 are fixed at both ends of the drive shaft 29, and a driven gear is fixed in the middle of the drive shaft 29. Five circumferentially distributed cutting blades 26 are provided on the outer sides of the two inner expansion components, each abutting against the hollow shaft 33. Each inner expansion component includes an expansion slide 27, which is fixed to the end of the hollow shaft 33. Guide gears 25 are rotatably mounted on each expansion slide 27, and each guide gear 25 is positioned relative to a corresponding... The drive gear 30 meshes, and the guide gear 25 is provided with five guide grooves evenly distributed in a circle. One end of the guide groove is close to the center of the guide gear 25, and the other end of the guide groove is far away from the center of the guide gear 25. The expansion slide 27 is provided with five expansion slide grooves evenly distributed in a circle. The slide rod 31 is slidably provided in the expansion slide groove. One end of the slide rod 31 is fixed with a guide rod. The position of the guide rod corresponds to the guide groove on the same side, and the guide rod is slidably set in the guide groove at the corresponding position. The other end of the slide rod 31 is fixed with an arc-shaped top plate 28. The middle position of the end of the arc-shaped top plate 28 is provided with a mounting groove 32. The cutting blade 26 is fixed on the mounting groove 32 of the two inner expansion components.

[0049] In this embodiment, by inserting the end of the rocker arm into the expansion shaft hole, the end of the rocker arm can rotate within the expansion shaft hole. The end of the rocker arm has a driving gear that can mesh with the driven gear. When the rocker arm is manually rotated, the rocker arm drives the driven gear to rotate through the driving gear at the end, thereby driving the transmission shaft 29 to rotate. The transmission shaft 29 drives two drive gears 30 to rotate. The two drive gears 30 respectively drive the guide gears 25 at corresponding positions to move. When the guide gears 25 move, they drive the guide rods at corresponding positions to move through the five guide grooves on them. The guide rods all drive the arc-shaped top plate 28 at corresponding positions. The arc-shaped top plate 28 drives the cutting blade 26 at corresponding positions to move.

[0050] The rotary tillage mechanism 3 includes five groups of evenly spaced expanding arc plates and five evenly spaced arc-shaped mud-blocking plates. Each group of expanding arc plates consists of two expanding arc plates 24. The two expanding arc plates 24 in each group are fixed to two arc-shaped top plates 28 at symmetrical positions on two inner expansion components. The two expanding arc plates 24 are symmetrically distributed on both sides of the mounting groove 32. The inner side of the expanding arc plate 24 abuts against the cutting blade 26, and the outer side of the expanding arc plate 24 is flush with the side of the arc-shaped top plate 28. One of the expanding arc plates in each group expands... Below each arc plate 24, there is a fixed arc-shaped mud-blocking plate. The arc-shaped mud-blocking plates are located between the arc-shaped top plates 28 at symmetrical positions of the two inner expansion components. The arc degree of the arc-shaped mud-blocking plate is equal to that of the arc degree of the arc-shaped top plate 28. The arc-shaped mud-blocking plates abut against the hollow shaft 33, and the two sides of the arc-shaped mud-blocking plates abut against two adjacent cutting blades 26 respectively. Several plowshare seats 20 are provided on the expansion arc plate 24. The positions of the several plowshare seats 20 of each expansion arc plate 24 are different. Plow blades 21 are detachably provided on each plowshare seat 20.

[0051] In this embodiment, during rotary tillage, the arc-shaped top plate 28 drives the corresponding expansion arc plate 24 to move, the expansion arc plate 24 drives a number of plow teeth 20 to move, the number of plow teeth 20 drives the corresponding plow blades 21 to move, and the number of plow blades 21 perform integrated soil turning and crushing operations by rotating. At the same time, it crushes some straw and weeds, improving the quality of rotary tillage. When the arc-shaped mud barrier is used to cut tangled weeds, it prevents soil from entering and ensures a clean working environment.

[0052] The working principle of this utility model is as follows: During operation, the electric rotary tiller is suspended on a small agricultural machine via the plow frame mechanism 1. After the water-cooled drive motor 5's water inlet pipe is installed, the small agricultural machine is driven to perform rotary tillage. The output shaft of the water-cooled drive motor 5 drives the plow shaft mechanism 22 to move via the sprocket pair. That is, the output shaft of the water-cooled drive motor 5 drives the left rotating shaft 23 to move via the sprocket pair, thereby driving the baffle 19 and the hollow shaft 33 to move. The hollow shaft 33 drives the anti-winding mechanism 6 and several rotary tillage mechanisms 3 to move. The several rotary tillage mechanisms 3 achieve integrated soil turning and breaking operations through rotation. That is, the arc-shaped top plate 28 drives the corresponding expansion arc plate 24 to move. 4 drives several plow teeth 20 to move, which in turn drives the corresponding plow blades 21 to move. The plow blades 21 rotate to perform integrated soil tillage and crushing operations, while simultaneously crushing some straw and weeds, improving the quality of rotary tillage. A water-cooled drive motor 5 ensures that the motor temperature is controllable during long-term operation, adapting to the needs of high-intensity farming. During rotary tillage, the control mechanism 2 moves, which drives the mud rake 4 to move. When the mud rake 4 is rotary tilling, the telescopic end of the electric push rod 16 drives the adjusting rod 13 to move. The adjusting rod 13 drives the corresponding connecting shaft 15 to move synchronously through two connectors 14. The synchronous movement of the two connecting shafts 15 drives the adjusting rod 13 to move synchronously. The baffle 11 moves, and adjusting the baffle 11 drives the mud-crushing plate 17 to move. The mud-crushing plate 17 drives several arc-shaped rake teeth 18 to move. The arc-shaped rake teeth 18 penetrate the soil, further breaking up the tilled soil clods and refining the soil structure. The mud-crushing rake 4 collects the uncrushed grass stems and straw to avoid affecting the rotary tillage quality. If straw and weeds become entangled on several rotary tillage plow mechanisms 3 and affect rotary tillage, the machine stops, and the anti-entanglement mechanism 6 is manually rotated. The anti-entanglement mechanism 6 drives several rotary tillage plow mechanisms 3 to expand. While expanding, the anti-entanglement mechanism 6 cuts the entangled straw and weeds, that is, by inserting the end of the rocker arm into the expansion shaft hole. The rocker arm can rotate within the expansion shaft hole, and its end has a drive gear that can mesh with the driven gear. When the rocker arm is manually rotated, the drive gear at the end drives the driven gear to rotate, which in turn drives the transmission shaft 29 to rotate. The transmission shaft 29 drives two drive gears 30 to rotate, and the two drive gears 30 drive the corresponding guide gears 25 to move. When the guide gears 25 move, they drive the corresponding guide rods to move through the five guide grooves on them. The guide rods drive the corresponding arc-shaped top plate 28, and the arc-shaped top plate 28 drives the corresponding cutting blade 26 to move. The cutting blade 26 removes tangled straw and weeds, reducing manual labor intensity and improving work efficiency.

[0053] In summary, the electric rotary tiller is suspended on new energy agricultural machinery through the plow frame mechanism 1, making it adaptable to various specifications of new energy agricultural machinery;

[0054] The water-cooled drive motor 5 drives the plow shaft mechanism 22 to move, and the plow shaft mechanism 22 drives the anti-winding mechanism 6 and several rotary tillage plow mechanisms 3 to move, so that the several rotary tillage plow mechanisms 3 rotate, realizing the integrated operation of soil turning and crushing.

[0055] The adjustment mechanism 2 drives the mud rake 4 to move. The mud rake 4 penetrates into the soil, breaks up the soil clods after tilling, refines the soil structure, and collects the unbroken grass stems and straw to ensure the quality of rotary tillage.

[0056] By cooperating with the anti-winding mechanism 6, the plow shaft mechanism 22, and the rotary tiller mechanism 3, the anti-winding mechanism 6 is driven by the plow shaft mechanism 22, thereby causing several rotary tiller mechanisms 3 to expand.
