Description

Technical Field

[0001] This invention belongs to the field of agricultural tillage equipment technology, specifically a hand-held tillage machine. Background Technology

[0002] Tillers are small tillage machines widely used in rice-growing areas of my country. They are mainly used for land preparation before tillage or sowing. Their core function is to break up and loosen the soil to create favorable conditions for subsequent cultivation. Among them, the walk-behind tiller is a common type of tiller. It can control the direction of movement and tillage through the handle and can also quickly switch agricultural implements to achieve multi-functional operation, thus enhancing its environmental adaptability.

[0003] A patent application with publication number CN215683154U discloses an electric tracked tillage machine, including a walking chassis, a mounting component, a rotary tillage component, a safety cover, and a control box. The walking chassis is equipped with a chassis frame, left and right drive wheels, and left and right walking motors. The mounting component includes an electro-hydraulic rod and a lower lifting arm. The rotary tillage component includes a frame, a rotary tillage blade shaft, a drive shaft, and a rotary tillage motor. This tillage machine can perform different tillage depth operations according to the tillage depth requirements, ensuring the quality of operation. The whole machine is electrically driven, easy to operate, highly automated, pollution-free, and has low labor intensity, making it suitable for greenhouse and open vegetable field operations.

[0004] The above-mentioned solutions still have some problems in practical application. When using the above-mentioned devices, due to the lack of a pre-treatment device for weeds, the tough fibrous structure of the weeds in the soil is difficult to break when they come into contact with the crushing blades and they will become entangled in the blade shaft. This not only causes obstruction of power transmission and a sharp increase in tillage resistance, but also causes abnormal wear of transmission components, and even serious failures such as overheating of the gearbox or breakage of the output shaft. If a crushing blade is added to the front end of the equipment, although it can partially solve the problem of cutting surface weeds, it cannot destroy the root system deep underground. Moreover, the crushed weed residues will accumulate in large quantities on the soil surface, forming a dense organic matter cover layer. This cover layer will seriously hinder the full contact between seeds and soil, resulting in uneven germination or inhibited seedling growth. At the same time, the residues will consume a large amount of nitrogen in the soil during decomposition, competing with crops for nutrients, forcing farmers to increase the amount of chemical fertilizers used to maintain yield, resulting in increased costs in the future.

[0005] Therefore, the present invention provides a walk-behind tillage machine. Summary of the Invention

[0008] Preferably, the tillage structure further includes a drive shaft, which is rotatably connected inside the protective cover, and several blades are connected to the drive shaft. The adjustment structure further includes: a sliding shaft, which is disposed at the upper end of the collecting cylinder; a screw, which is rotatably connected to the upper end of the sliding shaft; a sliding block, which is disposed at the upper end of the compression plate, and the upper end of the sliding block slides in a groove on the surface of the screw, and the sliding block slides on the surface of the sliding shaft; a motor, which is disposed at the upper end of the connecting frame; and a belt, one end of which is sleeved on the end of the motor, and the other end of which is sleeved on the surface of the rotating ring.

[0009] Preferably, the lower end of the protective cover is provided with a connecting block, the upper end of the connecting frame is provided with a first sliding rod, and the first sliding rod slides inside the connecting block, and a compression spring is sleeved on the surface of the first sliding rod.

[0010] Preferably, the rotating ring has a fixing block at one end near the abutting piece, the fixing block has a second sliding rod at one end near the abutting piece, and the abutting piece slides on the surface of the second sliding rod, and an adjusting spring is sleeved on the surface of the second sliding rod.

[0011] Preferably, the surface of the connecting frame has a ramp at one end near the notch.

[0012] Preferably, a lifting blade is slidably connected to one end of the collecting cylinder near the rotating ring.

[0013] Preferably, the lifting blade has a plurality of toothed blocks inside, and one end of the screw has a fixed gear, which meshes with the toothed blocks.

[0014] Preferably, one end of the collecting cylinder is provided with a water spray frame, and the water spray frame is movably installed with the connecting frame. The inside of the water spray frame is provided with a plurality of nozzles, and the nozzles extend into the inside of the collecting cylinder. A rubber sheet is slidably connected inside the water spray frame.

[0015] Preferably, one end of the sliding block is provided with a connecting rod, and the connecting rod is in contact with the rubber sheet.

[0016] Preferably, one end of the rubber sheet is provided with a third sliding rod, and the third sliding rod slides inside the connecting rod, and a telescopic spring is sleeved on the surface of the third sliding rod.

[0017] The beneficial effects of this invention are as follows: 1. The hand-held tillage machine of the present invention, by setting a connecting frame, when working, the drive wheel will drive the frame to move. At this time, the blade at the end of the connecting frame will contact the soil surface, and the soil will pass through the gaps on the blade surface. Some longer and difficult-to-break weeds will be stuck in the gaps in the blade, and as the frame continues to move, the weeds will move towards the inside of the connecting frame. At this time, the rotating ring is started to rotate. During the rotation of the rotating ring, the abutment plate will rotate together. In the initial state, since the adjusting spring is tight, the abutment plate will contact the inner wall of the connecting frame. When rotating to the connecting frame... When the frame opens, the adjusting spring releases its elasticity, pushing the abutment plate away from the fixed block. At this point, the abutment plate contacts and abuts against the weeds stuck in the blade's gap. As the abutment plate rotates, it pulls the weeds away, moving them to the gap between the rotating ring and the connecting frame. Some longer weeds are also uprooted as the blade engages and the abutment plate engages. The remaining soil on the surface of the weeds is discharged through the discharge hole, and the weeds continue to be moved by the abutment plate. When the abutment plate reaches the gap, the adjusting spring releases its elasticity, eliminating the contact between the abutment plate and the weeds. Ultimately, the weeds fall into the fixed ring and come into contact with the conveying auger. The auger then rotates, carrying the weeds towards the collection cylinder. During this transfer, the rotating blades of the auger exert squeezing and shearing forces on the weeds, breaking long weeds into shorter sections. The weeds are then collected inside the collection cylinder. After a period of operation, the drive wheel needs to be stopped for maintenance. At this time, the screw is started to rotate. Because the upper end of the sliding block moves in the groove on the screw surface and slides on the surface of the sliding shaft, the sliding block will then drive the compression... The plate slides inside the collecting cylinder, compressing the weeds inside into blocks for later processing. The collecting cylinder, connected to the fixing ring, is then removed, allowing the compressed weed blocks to be taken out and collected. During operation, this tillage machine removes weeds from the soil surface beforehand, uprooting longer weeds to prevent them from getting tangled on the drive shaft. These removed weeds are then transferred and collected to prevent large accumulations of weed debris on the soil surface. When it's time to remove these weed debris, the compression plate further compresses them into blocks for easy removal.

[0018] 2. The hand-held tillage machine of the present invention, by setting fixed tooth blocks and connecting rods, when the sliding block drives the compression plate to move, the rubber sheet connected to the sliding block will also be driven, thereby spraying water inside the water spray frame through the nozzle. This water will come into contact with the weeds during compression, thereby improving the weed forming efficiency. When the screw rotates, the fixed gear at one end of the screw will mesh with the tooth blocks, thereby driving the lifting blade to move downward, and finally cutting the compressed weeds so that the weed blocks can be removed later.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Example 1, as Figures 1 to 7 As shown, a hand-held tillager according to an embodiment of the present invention includes a frame 1, a diesel engine 2 at the upper end of the frame 1, drive wheels 4 at both ends of the frame 1, a handrail 3 at the upper end of the frame 1 near the diesel engine 2, and a tillage structure 5 at the lower end of the handrail 3. The tillage structure 5 includes a protective cover 51, which is located at one end of the frame 1. A plurality of blades 53 are rotatably connected inside the protective cover 51. An adjustment structure 6 is located at the end of the protective cover 51 near the drive wheels 4. The adjustment structure 6 includes a connecting frame 601, located at the lower end of the protective cover 51 near the drive wheels 4, and having a plurality of discharge holes 604 on its surface; and a shovel 6. 02. A shovel 602 is located at the lower end of the connecting frame 601; a rotating ring 605 is rotatably connected inside the connecting frame 601; a notch 606 is formed inside the connecting frame 601; an abutment piece 613 is located at the end of the rotating ring 605; a fixing ring 617 is located inside the rotating ring 605, and one end of the fixing ring 617 is fixedly connected to one end of the connecting frame 601, and a conveying auger 618 is rotatably connected inside the fixing ring 617; a collecting cylinder 603 is movably installed at one end of the fixing ring 617; and a compression plate 619 is slidably connected inside the collecting cylinder 603.

[0023] Specifically, this solution includes a walk-behind tillage machine, primarily used for land preparation work before tilling or sowing. During operation, the operator holds the handlebar 3 to control the direction of movement and tillage, and starts the diesel engine 2 to generate power, providing a stable energy source for the drive wheels 4. When the tillage machine moves over the soil to be worked on, the blades 53 are started to rotate. Before the soil enters the interior of the protective cover 51 and contacts the blades 53, the soil first contacts the shovel 602. The soil will pass through the gaps on the surface of the shovel 602. Some longer and harder-to-break weeds in the soil will get stuck in the gaps in the shovel 602, and as the frame 1 moves continuously, the weeds will move towards the interior of the connecting frame 601. At this point, rotation is initiated. As the ring 605 rotates, it drives the abutment piece 613 to rotate as well. Initially, the abutment piece 613 contacts the inner wall of the connecting frame 601. When it rotates to a position close to the blade 602, the abutment piece 613 contacts and abuts against the weeds stuck in the gap of the blade 602. As the abutment piece 613 continues to rotate, it pulls the weeds away and moves them to the gap between the rotating ring 605 and the connecting frame 601. Some longer weeds are also uprooted as the blade 602 engages with the abutment piece 613. At this point, the remaining soil on the surface of the weeds is discharged through the discharge hole 604, and the weeds are then further moved by the abutment piece 613. When the abutment piece 613 moves to the notch 606, it no longer contacts the inner wall of the connecting frame 601, and there is no abutment force between the abutment piece 613 and the weeds. This causes the weeds to fall into the fixing ring 617 and contact the conveying auger 618. At this point, the motor at one end of the conveying auger 618, located at the end of the connecting frame 601 away from the collecting cylinder 603, is activated to control the rotation of the conveying auger 618. The conveying auger 618 will then move the weeds towards the collecting cylinder 603. During this movement, the blades on the surface of the conveying auger 618 exert squeezing and shearing forces on the weeds as they rotate. This force can break the weeds, causing long weeds to break into shorter sections. The weeds will then be transferred to the collecting cylinder 603. The soil is collected internally, and then comes into contact with the blades 53. The blades 53 cut into the soil and throw it backward. The thrown soil hits the protective cover 51 and is blocked, falling to the ground in a fine fragment, forming a loose soil layer. As the frame 1 moves continuously, the land preparation work in this area can be completed. After working for a period of time, the diesel engine 2 needs to be stopped for rest. At this time, the compression plate 619 is started and moved. The compression plate 619 will compress the weeds inside the collection cylinder 603, so that the weeds can be compressed into blocks for subsequent processing. The collection cylinder 603, which is connected to the fixing ring 617, can be removed to take out the compressed weed blocks for collection. This tillage machine can remove weeds from the soil surface in advance during operation.Furthermore, longer weeds will be pulled up by the roots to prevent them from getting tangled on the blade 53. These removed weeds will be transferred and collected to prevent large accumulations of weed debris on the soil surface. When it's necessary to remove these weed debris later, the compression plate 619 can compress large amounts of weed debris into blocks for easier removal.

[0024] like Figures 1 to 7 As shown, the tillage structure 5 also includes a drive shaft 52, which is rotatably connected to the inside of the protective cover 51, and several blades 53 are connected to the drive shaft 52. The adjustment structure 6 also includes: a sliding shaft 621, which is located at the upper end of the collection cylinder 603; a screw 622, which is rotatably connected to the upper end of the sliding shaft 621; a sliding block 620, which is located at the upper end of the compression plate 619, and the upper end of the sliding block 620 slides in a groove on the surface of the screw 622 and slides on the surface of the sliding shaft 621; a motor 611, which is located at the upper end of the connecting frame 601; and a belt 616, one end of which is sleeved on the end of the motor 611, and the other end of which is sleeved on the surface of the rotating ring 605.

[0025] Specifically, when the rotating ring 605 needs to rotate, the motor 611 is started. The motor 611 will drive the rotating ring 605 to rotate via the belt 616. Then, when the diesel engine 2 is stopped for maintenance, the motor located at one end of the screw 622 is started. This motor is located at the upper end of the collecting cylinder 603 and is used to control the rotation of the screw 622. Since the upper end of the sliding block 620 moves in the groove on the surface of the screw 622 and the sliding block 620 slides on the surface of the sliding shaft 621, the sliding block 620 will slide along the surface of the sliding shaft 621. Since the sliding block 620 is connected to the compression plate 619, the sliding block 620 will drive the compression plate 619 to slide inside the collecting cylinder 603, thereby compressing the weeds inside the collecting cylinder 603 so that the weeds can be compressed into blocks. Then, reversing the screw 622 will reset the compression plate 619.

[0026] like Figure 3 As shown, the lower end of the protective cover 51 is provided with a connecting block 608, the upper end of the connecting frame 601 is provided with a first sliding rod 609, and the first sliding rod 609 slides inside the connecting block 608. A compression spring 610 is sleeved on the surface of the first sliding rod 609.

[0027] Specifically, by setting the connecting block 608, when the connecting frame 601 comes into contact with the soil, the first sliding rod 609 will slide inside the connecting block 608, and the compression spring 610 will continuously release elastic force, which not only ensures that the connecting frame 601 can fully contact the soil, but also that the connecting frame 601 has the ability to adaptively adjust its height, thus coping with more scenarios.

[0028] like Figures 1 to 4 As shown, the rotating ring 605 has a fixing block 612 at one end near the abutment piece 613, and the fixing block 612 has a second sliding rod 614 at one end near the abutment piece 613. The abutment piece 613 slides on the surface of the second sliding rod 614, and an adjusting spring 615 is sleeved on the surface of the second sliding rod 614.

[0029] Specifically, by setting the fixing block 612, in the initial state, since the adjusting spring 615 is taut, the abutment piece 613 will contact the inner wall of the connecting frame 601. When rotated to a position close to the blade 602, the adjusting spring 615 will release its elasticity, pushing the abutment piece 613 away from the fixing block 612, so that the abutment piece 613 can extend a longer distance, improving the success rate of the abutment piece 613 in transferring weeds. In addition, a sealing ring is fitted at the connection between the end of the abutment piece 613 and the second sliding rod 614 to prevent soil from entering the sliding area between the abutment piece 613 and the second sliding rod 614 during operation, thereby affecting the adjustment of the abutment piece 613.

[0030] like Figure 3 As shown, a ramp 607 is provided on the surface of the connecting frame 601 near the notch 606.

[0031] Specifically, when the abutment piece 613 is moved to the notch 606, the abutment piece 613 will no longer abut against the inner wall of the connecting frame 601. By setting the ramp 607, when the abutment piece 613 needs to be rotated again, the abutment piece 613 will contact the ramp 607, thereby avoiding the phenomenon of the abutment piece 613 getting stuck at the notch 606.

[0032] Example 2, as Figures 6 to 7 As shown in the first embodiment, another embodiment of the present invention is as follows: a lifting blade 624 is slidably connected to one end of the collecting cylinder 603 near the rotating ring 605.

[0033] Specifically, by setting up the lifting blade 624, when the compression plate 619 compresses the weeds, the lifting blade 624 is activated to move downwards, which can not only cut the compressed weeds, but also limit one end of the weed block so that the weed block can be removed later.

[0034] like Figures 6 to 7 As shown, the lifting blade 624 has several tooth blocks 626 inside, and one end of the screw 622 is provided with a fixed gear 625, which meshes with the tooth blocks 626.

[0035] Specifically, when the sliding block 620 moves the compression plate 619, the screw 622 will rotate continuously. At this time, the fixed gear 625 located at one end of the screw 622 will mesh with the tooth block 626, thereby driving the lifting blade 624 to move downward. Furthermore, a limiting plate is provided at the part of the lifting blade 624 near the tooth block 626. This plate ensures that the fixed gear 625 can only rotate inside the lifting blade 624 and always meshes with the tooth block 626, thus preventing misalignment between the fixed gear 625 and the lifting blade 624 during operation.

[0036] like Figures 6 to 7 As shown, a water spray frame 627 is provided at one end of the collection cylinder 603, and the water spray frame 627 is movably installed with the connecting frame 601. Several nozzles 623 are provided inside the water spray frame 627, and the nozzles 623 extend into the inside of the collection cylinder 603. A rubber sheet 628 is slidably connected inside the water spray frame 627.

[0037] Specifically, since some dry grass stems are brittle and hard when compressing weeds, they are prone to breaking into fragments and are difficult to shape. By setting up a water spray frame 627 and adding water inside the water spray frame 627, when the compression plate 619 compresses the weeds, the rubber sheet 628 is activated. The rubber sheet 628 will slide inside the water spray frame 627, thereby spraying the water inside the water spray frame 627 through the nozzle 623 onto the surface of the weeds, thereby softening the fibers and making the weeds easier to bend under pressure without breaking, thus improving the integrity of the grass block.

[0038] like Figures 6 to 7 As shown, one end of the sliding block 620 is provided with a connecting rod 629, and the connecting rod 629 is in contact with the rubber sheet 628.

[0039] Specifically, by setting the connecting rod 629, when the sliding block 620 drives the compression plate 619 to move, the sliding block 620 will drive the rubber sheet 628 to move together through the connecting rod 629, thereby spraying the water inside the water spray frame 627 out through the nozzle 623.

[0040] like Figures 6 to 7 As shown, a third sliding rod 630 is provided at one end of the rubber sheet 628, and the third sliding rod 630 slides inside the connecting rod 629. A telescopic spring 631 is sleeved on the surface of the third sliding rod 630.

[0041] Specifically, since the amount of weeds transferred to the collection cylinder 603 varies slightly each time, a third sliding rod 630 is set up so that when the rubber sheet 628 is pushed to contact the inner wall of the water spray frame 627, the water has already been sprayed. If the compression plate 619 is still moving at this time, the third sliding rod 630 will slide inside the connecting rod 629 to make adaptive adjustments.

[0042] Working principle: During use, the operator holds the handle bar 3 to control the direction of travel and tillage, and starts the diesel engine 2 to generate power, providing a stable energy source for the drive wheels 4. When the tiller moves over the soil to be worked on, the blades 53 are started to rotate. Before the soil enters the interior of the protective cover 51 and comes into contact with the blades 53, the soil will first come into contact with the shovel 602. The soil will pass through the gaps on the surface of the shovel 602. Some longer and harder-to-break weeds in the soil will get stuck in the gaps in the shovel 602. As the frame 1 moves, the weeds will move towards the interior of the connecting frame 601. At this time, the rotating ring 605 is started to rotate. During the rotation of the rotating ring 605, the abutment plate 6 will be driven. 13 rotate together. In the initial state, the abutment piece 613 will contact the inner wall of the connecting frame 601. When rotating to a position close to the blade 602, the abutment piece 613 will contact and abut against the weeds stuck in the gap of the blade 602. As the abutment piece 613 continues to rotate, it will move the weeds and transfer them to the gap between the rotating ring 605 and the connecting frame 601. Some longer weeds will also be uprooted as the blade 602 is engaged and the abutment piece 613 engages with them. At this time, the soil remaining on the surface of the weeds will be discharged through the discharge hole 604, and the weeds will continue to be moved by the abutment piece 613. When the abutment piece 613 moves to the notch 606, the abutment piece 613 no longer... The soil comes into contact with the inner wall of the connecting frame 601, and there is no contact force between the abutting piece 613 and the weeds. The weeds eventually fall into the interior of the fixing ring 617 and come into contact with the conveying auger 618. At this point, the conveying auger 618 is activated, causing it to rotate and move the weeds towards the collection cylinder 603. During this movement, the blades on the surface of the conveying auger 618 exert squeezing and shearing forces on the weeds as they rotate. This force breaks the weeds, causing long weeds to break into shorter sections. The weeds are then transferred to the inside of the collection cylinder 603 for collection. The soil then comes into contact with the blade 53, which cuts into the soil and throws it backward. The thrown soil hits the protective cover 51 and is blocked, falling in small fragments. On the ground, a loose soil layer is formed. As the vehicle frame 1 moves continuously, the land preparation work in this area can be completed. After working for a period of time, the diesel engine 2 needs to be stopped for rest. At this time, the screw 622 is started to rotate. Since the upper end of the sliding block 620 moves in the groove on the surface of the screw 622 and the sliding block 620 slides on the surface of the sliding shaft 621, the sliding block 620 will drive the compression plate 619 to slide inside the collection cylinder 603, thereby compressing the weeds inside the collection cylinder 603 so that the weeds can be compressed into blocks. Then, the screw 622 is reversed to reset the compression plate 619. At this time, the collection cylinder 603 connected to the fixing ring 617 is removed, and the compressed weeds can be taken out for collection.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
