Description

Technical Field

[0001] This utility model relates to the technical field of agricultural machinery, and in particular to a soil-raising machine used for soil-raising operations. Background Technology

[0002] Hilling is an agricultural technique used in the cultivation of root crops such as ginger and scallions, and vine vegetables such as cucumbers and tomatoes. It involves artificially thickening the soil cover to improve the root environment and promote plant growth. Hilling promotes root development, prevents root exposure, and provides resistance to lodging and insulation. Large-scale farmland operations typically use hilling machines. Chinese patent application 201610012478.5 discloses "An Electric Bucket Wheel Hilling Machine," publication number CN105612836A. This bucket wheel type ridging machine includes a main frame, a front frame, a rear frame, four wheels, and four wheel drive motors. The rear frame is hinged to the rear end of the main frame, and the front frame rotating frame is hinged to the end of the front frame mounting head. The front frame is hinged to the front frame rotating frame. The bucket wheel center is rotatably mounted at the center of the rear end of the main frame via a mounting shaft, and the bucket wheel drive motor is fixedly mounted on the main frame. A conveyor belt is installed in the middle of the main frame, and a V-shaped baffle is fixedly mounted on the main frame. A guide trough is provided on both sides of the conveyor belt. This bucket wheel type ridging machine, through its bucket wheel structure, achieves mechanized soil extraction and automatic crop ridging, improving agricultural production efficiency, saving labor, and reducing production costs. However, this bucket wheel soil extraction structure lacks rotary tillage and loosening capabilities, and experiences significant resistance during soil extraction, limiting its application to ridging operations in relatively loose soil. Another Chinese patent application, 200520078640.0, discloses "An Automatic Rigging Machine," with authorization announcement number CN2779825Y. This automatic soil-creeping machine includes a frame with front wheels, rear wheels, and handles. A diesel engine is mounted on the upper part of the front end of the frame. A soil-crushing wheel connected to the output shaft of the diesel engine is located below the front end of the frame. A scoop and a front roller are mounted on the front axle at the rear end of the soil-crushing wheel. A rear roller is also mounted on the frame. A conveyor belt with scrapers is mounted on the front and rear rollers. A soil-dividing trough is located at the lower end of the rear roller. A baffle is also mounted on the frame at the lower end of the soil-dividing trough. A gearbox is also mounted on the frame and connected to the output shaft of the diesel engine via the conveyor belt. The gearbox is connected to a reducer via the conveyor belt. The output shaft of the reducer is connected to the rear roller via a chain. This automatic soil-creeping machine uses the diesel engine to drive the movement of the soil-crushing wheel and the conveyor belt. The conveyor belt delivers soil into the soil-dividing trough, where it is then piled up by the baffle. However, in this structure where soil is piled up using dividing trenches and baffles, the soil relies on gravity to slide down from the dividing trenches. When the soil has a high moisture content, it can easily clog the dividing trenches, causing poor transport and affecting the piled-up effect. In addition, in order to allow the soil to slide outwards, the outer side of the dividing trench must be lower than the inner side, and the height of the outer side of the dividing trench limits the height of the piled-up. Utility Model Content

[0003] The purpose of this invention is to provide a soil-laying machine that does not block the channel, provides uniform soil covering, and achieves good soil covering effect.

[0004] The present invention discloses a soil-cultivating machine, comprising a frame suspended on a self-propelled power machine. The frame includes side plates on both sides of the traveling direction and a crossbeam fixedly connected between the side plates. A cutter shaft is mounted on the lower end of the frame and between the side plates via bearings, and a cutter head is fixedly mounted on the cutter shaft. A first gearbox is fixedly mounted above the cutter shaft and between the side plates, and a second gearbox is disposed behind the first gearbox. The first gearbox is provided with a first gearbox input shaft for connecting to the output end of the self-propelled power machine, and the output end of the first gearbox is drively connected to the cutter shaft. A first conveyor belt for longitudinal transmission and a second conveyor belt for transverse transmission are disposed between the first gearbox and the second gearbox. The second conveyor belt is located behind the first conveyor belt. The first conveyor belt is inclined at the front and high at the rear to receive soil thrown backward by the cutter head and transport the soil to the rear end. The rear end of the first conveyor belt is located above the feed end of the second conveyor belt, and the transmission direction of the second conveyor belt is perpendicular to the traveling direction.

[0005] With this solution, the soil dug up and thrown behind by the cutter head is conveyed to a higher position by the first conveyor belt and then to the side of the travel direction by the second conveyor belt. The soil conveying route is completely completed by the conveyor belt, which will not block the channel, ensure uniform soil covering, and achieve good soil covering effect.

[0006] Preferably, the first conveyor belt includes a first driving pulley, a first driven pulley, and a first chain belt sleeved between the first driving pulley and the first driven pulley; the second conveyor belt includes a second driving pulley, a second driven pulley, and a second chain belt sleeved between the second driving pulley and the second driven pulley; the first driving pulley is connected to the output end of the first gearbox via a first chain drive device, the first driving pulley is connected to the input end of the second gearbox via a second chain drive device, and the output end of the second gearbox is connected to the second driving pulley via a third chain drive device.

[0007] With this solution, the first and second conveyor belts are synchronized and linked, and both use the output power of self-propelled power machinery, requiring no additional power source.

[0008] Preferably, a three-point suspension bracket is fixedly connected to the upper end of the frame and above the cutter shaft.

[0009] With this solution, the soil-cultivating machine can be stably and reliably connected to a self-propelled power machine.

[0010] Preferably, a soil receiving platform is provided between the cutter shaft and the first driven transmission wheel. The soil receiving platform is used to receive the soil thrown backward by the cutter head on the cutter shaft. The two ends of the soil receiving platform are respectively fixedly connected to the side plates on both sides of the frame.

[0011] This solution fills the gap between the cutter shaft and the first driven drive wheel by filling the soil receiving platform, which can reduce the spillage when throwing soil backward, push more soil onto the first conveyor belt, and improve the soil covering efficiency.

[0012] Preferably, a third conveyor belt is provided behind the first conveyor belt, and the third conveyor belt is symmetrically arranged with the second conveyor belt and the conveying direction is opposite.

[0013] This method allows soil to be transported to both sides of the walking direction, achieving soil backfilling on both sides.

[0014] Preferably, a second drive sprocket for mounting a third chain drive device and a drive gear for connecting the third conveyor belt are fixedly installed on the second drive drive wheel of the second conveyor belt. The third conveyor belt includes a third drive drive wheel, a third driven drive wheel, and a third chain belt sleeved between the third drive drive wheel and the third driven drive wheel. A driven gear is fixedly installed on the third drive drive wheel, and the driven gear is constantly meshed with the drive gear.

[0015] This solution enables the third conveyor belt to work synchronously with the second conveyor belt.

[0016] In summary, the soil-laying machine of this utility model ensures that the soil is transported entirely by a conveyor belt, preventing channel blockage, ensuring uniform soil distribution, and achieving excellent soil-laying results. Attached Figure Description

[0025] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0026] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0028] like Figure 1 , Figure 2 As shown, the present invention discloses a tiller comprising a frame 1 for suspension on a self-propelled power machine. A three-point suspension bracket 90 is fixedly connected to the upper end of the frame 1, above the cutter shaft 3. The three-point suspension bracket is a key device in agricultural machinery connecting a tractor and its implements, achieving power transmission and attitude adjustment through three hinge points, and is widely used in tillage, transportation, and other fields. The three-point suspension bracket 90 can be connected to the rear end of the tractor. Auxiliary wheels are installed at the rear end of the frame 1.

[0029] like Figure 3 As shown, the frame 1 includes side plates 21 located on both sides of the walking direction and a crossbeam 2 fixedly connected between the two side plates.

[0030] A cutter shaft 3 is mounted on the lower end of the frame 1 between the two side plates via bearings. Both ends of the cutter shaft 3 extend through the side plates to their outer sides. Bearings or bushings are provided between the cutter shaft 3 and the side plates to allow the cutter shaft 3 to rotate freely while being supported by the side plates. A sprocket is fixedly mounted on the left side of the cutter shaft 3, and the cutter shaft 3 is driven to rotate via a chain mounted on the sprocket. A cutter head 4 is fixedly mounted on the cutter shaft 3. The cutter head 4 is a blade structure with its root vertically connected to the cutter shaft 3 and its head having a certain bending angle, which reduces the resistance when the cutter head 4 inserts into the soil. When the cutter shaft 3 rotates, the head of the cutter head 4 inserts into the soil and, with the rotation of the cutter shaft 3, digs up the soil and throws it backward.

[0031] A first gearbox 5 is fixedly installed above the cutter shaft 3 and between the two side plates. For example... Figure 1 , Figure 2 As shown, when the width of the first gearbox 5 is less than the gap between the two side plates, a horizontally arranged gearbox mounting platform can be welded between the two side plates, and the first gearbox 5 is fixedly mounted on the gearbox mounting platform. The first gearbox 5 is provided with a first gearbox input shaft 51 for connecting the output end of a self-propelled power machine, and the output end of the first gearbox 5 is connected to the cutter shaft 3. In use, the first gearbox input shaft 51 is connected to the power output shaft of a tractor or other self-propelled power machine through a coupling. Inside the first gearbox 5, the first gearbox input shaft 51 is connected to the output shaft of the output end through a bevel gear, and outputs power through the output shaft. The output shaft of the first gearbox 5 extends through the housing to the left and right sides of the frame 1, rotatably passing through the left side plate and the right side plate. Sprockets are fixedly mounted at both ends of the output shaft, and the left sprocket is connected to the cutter shaft 3 through a downwardly extending chain. The internal structure of the first gearbox 5 is known technology and will not be described in detail here.

[0032] A second gearbox 6 is provided behind the first gearbox 5; the second gearbox 6 is fixedly installed on a side plate on one side of the frame 1.

[0033] A first conveyor belt 7 for longitudinal transmission and a second conveyor belt 8 for transverse transmission are provided between the first gearbox 5 and the second gearbox 6. The second conveyor belt 8 is located behind the first conveyor belt 7. The first conveyor belt 7 is inclined at the front and lower at the rear to receive the soil thrown backward by the cutter head 4 and transport the soil to the rear end. The rear end of the first conveyor belt 7 is located above the feed end of the second conveyor belt 8, and the transmission direction of the second conveyor belt 8 is perpendicular to the travel direction. During farmland operations, the cutter shaft 3 rotates, the cutter head 4 digs the soil and throws the soil to the first conveyor belt 7 behind it. The first conveyor belt 7 transports the soil from front to back onto the second conveyor belt 8, and the second conveyor belt 8 then transports the soil from the middle to the side and piles it up on the side of the travel path, completing the soil covering operation.

[0034] like Figure 1 , Figure 2 In the illustrated embodiment, the input end of the second conveyor belt 8 is located on the right side and the output end is located on the left side. The soil conveyed by the first conveyor belt 7 enters the right side of the second conveyor belt 8, and as the second conveyor belt 8 rotates, it is conveyed to the left side and thrown out and scattered on the left side of the travel path, completing the left-side soil covering. Of course, as another embodiment of this utility model, the second conveyor belt can also be set to convey from left to right, scattering the soil on the right side of the travel path, completing the right-side soil covering.

[0035] As a further improvement to this utility model, such as Figure 2As shown, the first conveyor belt 7 includes a first driving pulley 71, a first driven pulley 72, and a first chain belt 73 sleeved between the first driving pulley and the first driven pulley; the second conveyor belt 8 includes a second driving pulley 81, a second driven pulley, and a second chain belt 83 sleeved between the second driving pulley and the second driven pulley; the first driving pulley 71 is connected to the output end of the first gearbox 5 via a first chain drive device 9, and the first driving pulley 71 is connected to the input end of the second gearbox 6 via a second chain drive device 10. The first driving pulley 71, the output shaft of the first gearbox 5, and the input shaft of the second gearbox 6 are arranged parallel to each other, and two sprockets are installed at one end of the first driving pulley 71. One sprocket is fitted with a chain of the first chain drive device 9 and is connected to the output shaft of the first gearbox 5; the other sprocket is fitted with a chain of the second chain drive device 10 and is connected to the input shaft of the second gearbox 6. After the input shaft on the first gearbox 5 receives power input from the power machinery, the output shaft on the first gearbox 5 rotates, which drives the first driven transmission wheel 72 to rotate through the first chain transmission device 9, driving the first conveyor belt 7 to run. At the same time, the power is transmitted to the second gearbox 6 through the second chain transmission device 10, driving the second gearbox 6 to work.

[0036] The output end of the second gearbox 6 is connected to the second drive pulley 81 via a third chain drive device 11. The third chain drive device 11 includes a sprocket fixedly mounted on the output shaft of the second gearbox 6, a sprocket fixedly mounted on the end of the second drive pulley 81, and a chain sleeved between the two sprockets. When the second gearbox 6 is working, its output shaft rotates, driving the second drive pulley 81 to rotate via the sprockets and chain, thereby driving the second conveyor belt 8 to operate.

[0037] Furthermore, as a further improvement of this utility model, a soil-receiving platform 91 is provided between the cutter shaft 3 and the first driven transmission wheel. The soil-receiving platform 91 is used to receive the soil thrown backward by the cutter head 4 on the cutter shaft 3. The two ends of the soil-receiving platform 91 are respectively fixedly connected to the side plates 21 on both sides of the frame 1. Figure 4 As shown, the soil receiving platform 91 is a strip-shaped flat plate set parallel to the ground, with upward-bent hanging ears 92 at both ends, which are bolted to the side plate 21.

[0038] like Figure 5 , Figure 6 As shown, as another embodiment of this utility model, it differs from... Figure 1 , Figure 2In this embodiment, a third conveyor belt 85 is provided behind the first conveyor belt 7. The third conveyor belt 85 is symmetrically arranged with the second conveyor belt 8 and the conveying direction is opposite. After the first conveyor belt 7 transports the soil to the rear end, the third conveyor belt 85 and the second conveyor belt 8 respectively transport the soil to both sides, scattering the soil on the left and right sides of the travel route to form double-sided soil covering.

[0039] In this embodiment, the output shaft of the second gearbox 6 simultaneously drives the third conveyor belt 85 and the second conveyor belt 8 to rotate, and the rotation directions of the third conveyor belt 85 and the second conveyor belt 8 are opposite. A second drive sprocket 86 for mounting the third chain drive device 11 and a drive gear 87 for connecting the third conveyor belt 85 are fixedly mounted on the second drive pulley of the second conveyor belt 8. The third conveyor belt 85 includes a third drive pulley, a third driven pulley, and a third chain 851 sleeved between the third drive pulley and the third driven pulley. A driven gear 88 is fixedly mounted on the third drive pulley, and the driven gear 88 is constantly meshed with the drive gear 87. While the output shaft of the second gearbox 6 drives the second conveyor belt 8 to rotate via the third chain drive device 11, the drive gear 87 drives the third conveyor belt 85 to rotate via the driven gear 88.

[0040] Similar to the single-sided soil-laying embodiment, in the double-sided soil-laying embodiment, the input end of the first gearbox 5 is connected to the output end of a self-propelled power machine and receives power input. The output shaft of the first gearbox 5 extends through the housing to the left and right sides of the frame 1, rotatably passing through the left and right side plates. Sprockets are fixedly installed at both ends of the output shaft. Figure 6 As shown, the left side of the output shaft of the first gearbox 5 is connected to the cutter shaft 3 via a sprocket and chain drive mechanism. Figure 5 As shown, the right side of the output shaft of the first gearbox 5 is connected to the first drive pulley 71 via the first chain drive device 9. Simultaneously, the first drive pulley 71 is connected to the input end of the second gearbox 6 via the second chain drive device 10. When the output shaft of the first gearbox 5 rotates, it drives the cutter shaft 3 to rotate, simultaneously driving the first conveyor belt 7 via the first chain drive device 9. Power is then input to the second gearbox 6 via the second chain drive device 10, which in turn drives the second conveyor belt 8 and the third conveyor belt 85.

[0041] like Figure 5 As shown, in order to avoid interference between the second chain drive device 10 and the third conveyor belt 85, a tension sprocket 101 can be provided on the side plate on the right side of the frame 1. The chain in the second chain drive device 10 is sleeved on the tension sprocket 101. On the one hand, the chain can be kept taut, and on the other hand, the shape of the chain transmission route can be changed to avoid the third conveyor belt 85.

[0042] During farmland operations, the cutter shaft 3 rotates, the cutter head 4 digs up the soil and throws it to the first conveyor belt 7 behind. The first conveyor belt 7 transports the soil from front to back to the second conveyor belt 8 and the third conveyor belt 85. The second conveyor belt 8 and the third conveyor belt 85 then transport the soil from the middle to both sides and pile it up on both sides of the travel route, completing the double-sided soil covering operation.
