Description

Technical Field

[0001] This invention relates to sugarcane ridging machines, specifically to a hopper-lifting type sugarcane inter-rowing and ridging machine. Background Technology

[0002] Sugarcane is one of the main raw materials for sugar production. In major sugarcane growing areas, the wide-narrow row planting pattern is widely adopted. Traditional sugarcane tillage and hilling machines cannot meet the field management requirements of wide-narrow row planting. They can only hill the outer side of the sugarcane on the narrow row ridges, but cannot hill the middle of the sugarcane on the narrow row ridges. This results in incomplete hilling of the sugarcane, leading to poor lodging resistance in the later stages of sugarcane growth and making it difficult for mechanical harvesting.

[0003] The invention application with publication number CN106416471A discloses a wide-narrow row sugarcane ridging machine, including a fixed frame, a ridging device, a soil crushing and throwing device for crushing and throwing soil, and a drive mechanism for driving the soil crushing and throwing device to rotate. The ridging device and the drive mechanism are both installed on the fixed frame. The soil crushing and throwing device is connected to the drive mechanism. The ridging device is located behind the soil crushing and throwing device. The ridging device includes a soil separating device and a soil inlet box. Both ends of the soil separating device have soil outlets. One end of the soil inlet box is connected to the soil inlet, and the other end extends above the soil crushing and throwing device and bends towards the soil crushing and throwing device. When ridging is performed, the tractor and the fixed frame are connected by a three-point suspension. The tractor drives the sugarcane inter-row ridging machine. The soil crushing and throwing device crushes the soil on the wide row furrow and throws the soil into the soil separating device. The soil separating device transports the soil to the middle of the narrow row ridge.

[0004] The aforementioned hilling machine can effectively and completely hill sugarcane planted in both wide and narrow rows. However, in this hilling machine, each hilling shaping module needs to break up the soil in two wide row ditches to complete the complete hilling of two rows of sugarcane on one narrow row ridge. The hilling operation has low efficiency and a high rate of seedling damage. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned problems and provide a hopper-lifting sugarcane inter-row cultivation and ridging machine. This machine can complete the ridging of sugarcane on two narrow rows of ridges by breaking up the soil in a single wide row of furrows. It has high operating efficiency and occupies little space when operating in the field, effectively avoiding damage to the seedlings.

[0006] The objective of this invention is achieved through the following technical solution:

[0007] A hopper-lifting sugarcane inter-tillage and ridging machine includes a frame and a digging mechanism, a soil conveying mechanism, and a soil separating mechanism mounted on the frame.

[0008] The frame is connected to the traction device;

[0009] The digging mechanism includes a rotary tillage assembly, a rotary tillage drive mechanism, and a rotary tillage transmission mechanism; the rotary tillage assembly includes a rotary tillage blade, which is provided with a soil throwing section for throwing soil onto the soil conveying mechanism.

[0010] The soil conveying mechanism includes a conveying hopper, a synchronous conveying assembly, a conveying transmission mechanism, and a conveying drive mechanism; the synchronous conveying assembly includes a synchronous conveying chain and synchronous conveying sprockets, and there are two synchronous conveying chains; there are two sets of synchronous conveying sprockets, and each set of synchronous conveying sprockets includes at least two synchronous conveying sprockets; the two synchronous conveying chains are respectively arranged on the two sets of synchronous conveying sprockets; there are multiple synchronous conveying hoppers, which are arranged sequentially between the two synchronous conveying chains;

[0011] The soil separating mechanism includes a soil separating conveyor belt and a soil separating drive mechanism for driving the soil separating conveyor belt to operate. There are two soil separating conveyor belts and the two soil separating conveyor belts have opposite conveying directions. The conveying direction of the soil separating conveyor belt is perpendicular to the working forward direction.

[0012] In operation, the rotary tiller loosens the soil and feeds it into the conveyor hopper. The conveyor hopper moves above the two soil-dividing conveyor belts along the synchronous conveyor chain and feeds the soil onto the two soil-dividing conveyor belts. The two soil-dividing conveyor belts transport the soil in opposite directions and unload the soil onto two narrow rows of ridges.

[0013] The working principle of the above-mentioned hopper-lifting sugarcane inter-row tiller is as follows:

[0014] During operation, the hilling machine is pulled into the sugarcane field by a traction device, positioning the rotary tillers in the wide-row furrows. The rotary tiller drive mechanism drives the rotary tillers to rotate, loosening the soil in the furrows and throwing it onto the conveyor hopper of the soil conveying mechanism. The conveyor drive mechanism then drives the synchronous conveyor chain, transporting the hopper from behind the rotary tillers to above the soil-distributing conveyor belts. As the hopper tilts downwards, the soil automatically falls onto two soil-distributing conveyor belts. Driven by the soil-distributing drive mechanism, the two conveyor belts transport soil in opposite directions and unload it onto two narrow-row ridges. Following this operation, the hilling work is carried out sequentially along the direction of the sugarcane planting, pulled by the traction device.

[0015] In a preferred embodiment of the present invention, the rotary tillage drive mechanism is constituted by the power output end of the traction device.

[0016] In a preferred embodiment of the present invention, the rotary tillage assembly further includes a rotary tillage shaft, and the rotary tillage blades are disposed on the rotary tillage shaft;

[0017] The rotary tillage transmission mechanism includes a transmission box and a transmission shaft. The transmission box includes a primary transmission box and a secondary transmission box. The transmission shaft connects the primary transmission box and the secondary transmission box. The secondary transmission box is connected to the rotary tillage shaft.

[0018] In a preferred embodiment of the present invention, the synchronous conveying chain is configured as a two-stage stepped structure; in the working state, the conveying hopper located on the surface of the first-stage step receives the soil thrown by the rotary tiller blades, and the conveying hopper located on the back of the second-stage step dumps the soil onto the soil-distributing conveyor belt below.

[0019] In a preferred embodiment of the present invention, the conveying hopper is a half-cylinder structure with both ends closed, and the two ends of the conveying hopper are respectively rotatably connected to two synchronous conveying chains.

[0020] Furthermore, a self-unloading guide is provided on the side of one end of the conveying hopper;

[0021] The soil conveying mechanism also includes a self-unloading passive pusher plate, which is fixedly installed on the conveying path of the self-unloading guide. This plate is located above one of the soil-distributing conveyor belts and below the synchronous conveyor chain. With this structure, when the synchronous conveyor chain moves the conveying hopper above the soil-distributing conveyor belt and the hopper is located in the lower half of the synchronous conveyor chain, the self-unloading passive pusher plate blocks the front of the self-unloading guide. As the self-unloading guide continues to move forward, the self-unloading passive pusher plate pushes the guide backward, causing the conveying hopper to tilt at a certain angle. At this point, the hopper is in a tilted state, and the soil in the hopper automatically falls onto the soil-distributing conveyor belt below, thus achieving a self-unloading operation – a very ingenious design.

[0022] Furthermore, the self-unloading passive push plate is provided with a gradually rising flipping extrusion surface and a gradually falling rotation limiting surface, and the flipping extrusion surface and the rotation limiting surface are symmetrically arranged.

[0023] The side of one end of the conveying hopper is also provided with a rotation limiting part that cooperates with the rotation limiting curved surface. With the above structure, when the self-unloading guide part contacts the self-unloading passive push plate, the conveying hopper can be rotated stably and slowly under the guidance of the flipping extrusion curved surface; after the rotation, the rotation limiting curved surface and the rotation limiting part ensure that the conveying hopper rotates smoothly and reduces shaking.

[0024] Furthermore, an anti-rotation structure is provided between the side of the other end of the conveying hopper and the corresponding synchronous conveying chain. This anti-rotation structure includes anti-rotation posts and anti-rotation limiting parts. The anti-rotation posts are fixedly installed on the synchronous conveying chain, and there are multiple anti-rotation posts located between the rotation centers of two adjacent conveying hoppers. The anti-rotation limiting parts are installed on the conveying hopper and include upper and lower anti-rotation limiting parts. When the conveying hopper is conveying horizontally, the upper anti-rotation limiting part of the conveying hopper is limited above the corresponding anti-rotation post, and the lower anti-rotation limiting part of the conveying hopper is limited below the corresponding anti-rotation post. Through the above structure, the upper and lower anti-rotation limiting parts can prevent the conveying hopper from overturning, so that the conveying hopper can smoothly receive the soil.

[0025] In a preferred embodiment of the present invention, the conveying drive mechanism is constituted by the power output end of the traction device.

[0026] In a preferred embodiment of the present invention, the conveying transmission mechanism includes a primary transmission box, a transmission shaft, and a sprocket transmission structure; the transmission shaft is connected between the primary transmission box and the sprocket transmission structure, and the sprocket transmission structure is connected to the synchronous conveying sprocket.

[0027] In a preferred embodiment of the present invention, the soil-dividing drive mechanism includes a soil-dividing drive motor and a soil-dividing transmission assembly, wherein the soil-dividing transmission assembly includes a soil-dividing transmission belt and a soil-dividing transmission pulley.

[0028] In a preferred embodiment of the present invention, the excavation mechanism, the soil conveying mechanism, and the soil separating mechanism are each provided in two sets;

[0029] The two sets of digging and soil conveying mechanisms share a single drive mechanism.

[0030] Compared with the prior art, the present invention has the following advantages:

[0031] 1. The hilling machine of this invention can complete the hilling of sugarcane on two narrow ridges by breaking up the soil in a single wide row ditch, which is highly efficient.

[0032] 2. The horizontal soil conveying efficiency is high, and the height is appropriate, so that the sugarcane will not be damaged. Attached Figure Description

[0040] To enable those skilled in the art to fully understand the technical solutions of the present invention, the present invention will be further described below in conjunction with embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0041] See Figure 1-2 The hopper-lifting sugarcane tillage and ridging machine of this embodiment includes a frame 1 and a digging mechanism, a soil conveying mechanism, and a soil separating mechanism mounted on the frame 1. Each of the digging, soil conveying, and soil separating mechanisms has two sets, and the two sets of digging and soil conveying mechanisms share a single drive mechanism. The frame 1 is connected to a traction device (e.g., a tractor). The frame 1 has a connection part for three-point suspension with the traction device, and this connection part has several adjustment holes. By connecting to different adjustment holes, the traction device can adjust the pitch state of the sugarcane ridging machine, thereby adjusting the pitch state of the digging mechanism.

[0042] See Figure 1-3 The digging mechanism includes a rotary tillage assembly, a rotary tillage drive mechanism, and a rotary tillage transmission mechanism. The rotary tillage assembly includes a rotary tillage blade 2 and a rotary tillage shaft, with the rotary tillage blade 2 mounted on the rotary tillage shaft. The rotary tillage blade 2 is provided with a soil throwing section 2-1 for throwing soil onto a soil conveying mechanism. The rotary tillage drive mechanism is composed of the power output end of a traction device. The rotary tillage transmission mechanism includes a transmission box and a transmission shaft 5. The transmission box includes a primary transmission box 3 and a secondary transmission box 4. The transmission shaft 5 connects the primary transmission box 3 and the secondary transmission box 4, and the secondary transmission box 4 is connected to the rotary tillage shaft.

[0043] See Figure 1-2 and Figure 4-5The soil conveying mechanism includes a soil separating shell 8, a conveying hopper 6, a synchronous conveying assembly, a conveying transmission mechanism, and a conveying drive mechanism; the soil separating shell 8 is provided with a soil inlet and a soil outlet; the conveying hopper 6 and the synchronous conveying assembly are disposed inside the soil separating shell 8; the synchronous conveying assembly includes a synchronous conveying chain 7 and a synchronous conveying sprocket, the synchronous conveying chain 7 is provided with two chains; the synchronous conveying sprockets are provided with two sets, and each set of synchronous conveying sprockets includes at least two synchronous conveying sprockets; the two synchronous conveying chains 7 are respectively disposed on the two sets of synchronous conveying sprockets; the synchronous conveying hoppers 6 are provided with multiple chains and are arranged sequentially between the two synchronous conveying chains 7.

[0044] Furthermore, the conveying transmission mechanism includes the primary transmission box 3, the transmission shaft 5, and the sprocket transmission structure; the transmission shaft 5 is connected between the primary transmission box 3 and the sprocket transmission structure, and the sprocket transmission structure is connected to the synchronous conveying sprocket.

[0045] See Figure 1-2 The soil separating mechanism includes a soil separating conveyor belt 9 and a soil separating drive mechanism for driving the soil separating conveyor belt 9. There are two soil separating conveyor belts 9 in the same group, and the conveying directions of the two soil separating conveyor belts 9 are opposite. The conveying direction of the soil separating conveyor belt 9 is perpendicular to the working forward direction. In the working state, the rotary tiller 2 loosens the soil and feeds it to the conveying hopper 6. The conveying hopper 6 moves above the two soil separating conveyor belts 9 with the synchronous conveying chain 7 and feeds the soil onto the two soil separating conveyor belts 9. The two soil separating conveyor belts 9 convey the soil in opposite directions and unload the soil onto two narrow rows of ridges.

[0046] See Figure 1-2 and Figure 4-5 The synchronous conveying chain 7 is configured as a two-stage stepped structure; in the working state, the conveying hopper 6 located on the surface of the first-stage step receives the soil thrown by the rotary tiller 2, and the conveying hopper 6 located on the back of the second-stage step dumps the soil onto the soil distribution conveyor belt 9 below.

[0047] See Figure 1-2 and Figure 4-5 The conveying hopper 6 is a half-cylinder structure with both ends closed, and the two ends of the conveying hopper 6 are respectively rotatably connected to two synchronous conveying chains 7.

[0048] See Figure 4-5 and Figure 7The conveying hopper 6 has a self-unloading guide 6-1 on one side of one end. The soil conveying mechanism also includes a self-unloading passive pusher 10, which is fixedly installed on the conveying path of the self-unloading guide 6-1. The self-unloading passive pusher 10 is located above one of the soil-dividing conveyor belts 9 and below the synchronous conveying chain 7. With the above structure, when the synchronous conveying chain 7 drives the conveying hopper 6 to move above the soil-dividing conveyor belt 9 and the conveying hopper 6 is located in the lower half of the synchronous conveying chain 7, the self-unloading passive pusher 10 blocks the front of the self-unloading guide 6-1. As the self-unloading guide 6-1 continues to move forward, the self-unloading passive pusher 10 pushes the self-unloading guide 6-1 backward, causing the conveying hopper 6 to flip at a certain angle. At this time, the conveying hopper 6 is in a tilted state, so the soil in the conveying hopper 6 automatically falls onto the soil-dividing conveyor belt 9 below, thus realizing the self-unloading operation, which is very ingenious.

[0049] See Figure 4-5 and Figure 7-10 The self-unloading passive push plate 10 is provided with a gradually rising flipping and pressing curved surface and a gradually falling rotation limiting curved surface, which are symmetrically arranged. A rotation limiting part 6-2, which cooperates with the rotation limiting curved surface, is also provided on the side of one end of the conveying hopper 6. With this structure, when the self-unloading guide part 6-1 contacts the self-unloading passive push plate 10, the conveying hopper 6 can rotate stably and slowly under the guidance of the flipping and pressing curved surface. After rotation, the rotation limiting surface and the rotation limiting part 6-2 ensure that the conveying hopper 6 rotates smoothly, reducing swaying.

[0050] See Figure 6 and Figure 11 An anti-rotation structure is provided between the side of the other end of the conveying hopper 6 and the corresponding synchronous conveying chain 7. This anti-rotation structure includes an anti-rotation post 11 and an anti-rotation limiting part. Multiple anti-rotation posts 11 are fixedly mounted on the synchronous conveying chain 7 and are located between the rotation centers of two adjacent conveying hoppers 6. The anti-rotation limiting part is mounted on the conveying hopper 6 and includes an upper anti-rotation limiting part 6-3 and a lower anti-rotation limiting part 6-4. When the conveying hopper 6 is conveying horizontally, the upper anti-rotation limiting part 6-3 of the conveying hopper 6 is limited above the corresponding anti-rotation post 11, and the lower anti-rotation limiting part 6-4 of the conveying hopper 6 is limited below the corresponding anti-rotation post 11. Through this structure, the upper anti-rotation limiting part 6-3 and the lower anti-rotation limiting part 6-4 can prevent the conveying hopper 6 from overturning, ensuring that the conveying hopper 6 can smoothly receive the soil.

[0051] Furthermore, the soil-distributing drive mechanism includes a soil-distributing drive motor and a soil-distributing transmission assembly, which includes a soil-distributing transmission belt and a soil-distributing transmission pulley; the specific structure can refer to the existing conveyor belt structure.

[0052] See Figure 1-2 The working principle of the hopper-lifting sugarcane tiller and ridging machine in this embodiment is as follows:

[0053] During operation, the traction device pulls the hilling machine into the sugarcane field, positioning the rotary tiller blades 2 in the wide-row furrows. The rotary tiller drive mechanism drives the blades 2 to rotate, loosening the soil in the furrows and throwing the soil through the throwing section 2-1 onto the conveying hopper 6 of the soil conveying mechanism. The conveying drive mechanism drives the synchronous conveying chain 7, transporting the conveying hopper 6 from behind the rotary tiller blades 2 to above the soil-distributing conveyor belts 9. As the conveying hopper 6 tilts downwards, the soil automatically falls onto the two soil-distributing conveyor belts 9. Driven by the soil-distributing drive mechanism, the two conveyor belts 9 transport soil in opposite directions and unload it onto the two narrow-row ridges. Following this operation, the hilling work is carried out sequentially along the direction of sugarcane planting, pulled by the traction device.

[0054] The above are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above content. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
