Description

Technical Field

[0001] The invention relates to the field of paddy field tillage, and in particular to a three-folding rotary tillage and pulping integrated machine. Background Art

[0002] Especially in recent years, with the adjustment of the planting structure in my country's southern rice producing areas, the planting areas of rice, wheat, rice oil, rice tobacco, etc. have increased rapidly, which has put forward higher requirements for land preparation machinery, which can not only complete the requirements of deep plowing, soil crushing, and leveling in dry land operations, but also meet the needs of paddy field slurrying and paddy field leveling operations.

[0003] However, during the paddy field beating process, the stones in the paddy field will damage the blades used for stirring the slurry. Specifically, large stones are more likely to collide with the blades during the stirring process, thereby increasing the risk of damage to the blades. Although smaller stones have less direct impact on the blades, if there are a large number of them, they may gradually wear out the blades through long-term friction and collision. Therefore, before the existing paddy field operations, the stones in the paddy field need to be cleaned in advance to minimize the chance of collision between the blades and stones. However, although large stones are easy to clean, small stones are small in size due to their large number. The process of cleaning small stones is not only time-consuming and labor-intensive, increasing unnecessary labor expenses, but also increases the difficulty of cleaning when straw and stones are mixed together.

[0004] Existing beaters generally solve the problem of stone-blade collision by increasing the wear resistance and impact resistance of the blade. However, this method requires the use of more expensive alloy steel and frequent maintenance of the blade, which cannot solve the problem from the root. Moreover, when the stone collides with the blade, the stone will still damage the blade and affect the sharpness of the blade. Summary of the invention

[0005] Based on this, it is necessary to provide a three-fold rotary tillage and pulping machine to address the existing technical problems.

During this process, the cylinder structure can ensure the stability of its movement, and the knife shaft 4 arranged under the sub-frame 2 and the knife shaft 4 arranged under the main frame 1 are disassembled and connected through a clutch to ensure that the knife shaft 4 can operate normally during operation.

[0049] When the operation is carried out, as the device moves, the knife shaft 4 rotates and drives several transmission mechanisms 12 to start through the knife shafts 4 at the lower ends of the two sub-frames 2. After the several transmission mechanisms 12 are started, they will drive several rake frames 30 to move along the side plates 8. During the movement of the rake frames 30, the stones in the paddy field will be hooked up through the several stone hooks 32 and finally put into the stone collecting box 46.

[0050] In order to realize the power transmission between the transmission mechanism 12 and the knife shaft 4, the following features are also specifically provided:

[0051] The transmission mechanism 12 also includes two main gears 16 and two sub-gears 17. The transmission mechanism 12 arranged below the side frame 7 also includes a main sprocket 13, a main chain 14 and a sub-sprocket 15.

When the knife shaft 4 rotates, the knife shaft 4 will drive the main sprocket 13 fixedly connected thereto to rotate, the main sprocket 13 will drive the sub-sprocket 15 to rotate through the main chain 14, and the sub-sprocket 15 will drive the sub-gear 17 to rotate through the main gear 16.

[0052] In order to achieve that all transmission mechanisms 12 maintain power transmission, the following features are also specifically provided:

When the main gear 16 rotates, the main gear 16 will drive the power gear 23 to rotate through the fixed gear 22, and the power gear 23 will drive the power shaft 24 fixedly connected thereto to rotate, and when the power shaft 24 rotates, the power shaft 24 arranged below the side frame 7 will drive the power shaft 24 arranged below the middle frame 6 to rotate through the clutch, thereby realizing that when the rotary tillage and beating assembly 3 is in operation, a plurality of transmission mechanisms 12 can be started synchronously.

[0054] In order to further supplement the specific structure of the transmission mechanism 12, the following features are also specifically provided:

[0055] The transmission mechanism 12 also includes two first sprockets 18, two second sprockets 19 and two first chains 20. The two first sprockets 18 are respectively arranged on the side of the corresponding side plate 8 away from the sub-gear 17 and are respectively coaxially fixedly connected with the two sub-gears 17. The two second sprockets 19 are respectively arranged above the two first sprockets 18 and are rotatably connected with the side plate 8. One end of the two first chains 20 is respectively connected to the two first sprockets 18, and the other end is respectively connected to the two second sprockets 19. When the main gear 16 rotates, the main gear 16 will drive the power shaft 24 to rotate through the sub-gear 17. After the power shaft 24 rotates, it will drive the sub-gear 17 at the other end to rotate. Then, the first sprockets 18 on the two side plates 8 will rotate. Finally, the first sprocket 18 will drive the second sprocket 19 to rotate through the first chain 20.

[0056] In order to facilitate the first chain 20 to drive the plurality of rake frames 30 to move, the following features are also specifically provided:

[0057] The transmission mechanism 12 further includes a plurality of stone screening mechanisms 28, which are arranged in an array at equal intervals along the first chains 20 on the two side plates 8, and the plurality of stone screening mechanisms 28 are respectively fixedly connected to the plurality of chain nails 21 on the first chain 20, and the two ends of the plurality of rake frames 30 are respectively fixedly connected to the plurality of stone screening mechanisms 28 on the two side plates 8. When the first chain 20 rotates, the first chain 20 drives the plurality of stone screening mechanisms 28 to move through the plurality of chain nails 21, and when the plurality of stone screening mechanisms 28 move, the plurality of rake frames 30 are driven to move, and the rake frames 30 will hook out stones on the paddy field through the stone hooks 32 during the movement.

[0058] In order to supplement the specific structure of the stone screening mechanism 28, the following features are also specifically provided:

[0059] The stone screening mechanism 28 includes a side plate 29, a carrier plate 34, a main pressure plate 35 and a secondary pressure plate 37. The carrier plate 34 is fixedly connected to the chain nail 21 coaxially, the side plate 29 is fixedly connected to one end of the carrier plate 34 away from the side plate 8, the main pressure plate 35 is fixedly connected to one end of the chain nail 21 away from the carrier plate 34 in a horizontal state, and the secondary pressure plate 37 is fixedly connected to one end of the main pressure plate 35 away from the carrier plate 34 in a vertical state. When the first chain 20 rotates, the first chain 20 will drive the carrier plate 34 to move through the chain nail 21, and the carrier plate 34 will drive the main pressure plate 35 and the secondary pressure plate 37 to move. In this process, the side plate 29 fixedly connected to the carrier plate 34 will keep moving at the same angle to prevent the rake frame 30 from moving and affecting the efficiency of stone screening.

[0060] In order to limit the main pressure plate 35 and the auxiliary pressure plate 37, the following features are also specifically provided:

[0061] The stone screening mechanism 28 also includes two main pressure wheels 36 and two auxiliary pressure wheels 38. The transmission mechanism 12 also includes two limit arc plates 25, two lateral arc plates 26 and two end arc blocks 27. A limit arc groove 9 is formed on the side of the side plate 8 close to the rake frame 30. The two limit arc plates 25 are arranged in the limit arc groove 9 in a left-right symmetrical state and are fixedly connected to the side plate 8. The two lateral arc plates 26 are respectively fixedly connected to the side of the two limit arc plates 25 away from the side plate 8. The two end arc blocks 27 are respectively arranged at the upper and lower ends of the limit arc groove 9. The two main pressure wheels 36 are respectively rotatably connected to the two ends of the main pressure plate 35, the main pressure wheel 36 is rollingly connected to one side of the limit arc groove 9, the two auxiliary pressure wheels 38 are respectively rotatably connected to the two ends of the auxiliary pressure plate 37, and the auxiliary pressure wheel 38 is rollingly connected to the other side of the lateral arc plate 26. When the carrier 34 moves, the main pressure wheel 36 and the auxiliary pressure wheel 38 will be limited by the lateral arc plate 26 to ensure that the main pressure plate 35 always remains in a horizontal state during the movement, and the auxiliary pressure plate 37 always remains in a vertical state during the movement. The two end arc blocks 27 will ensure that the main pressure plate 35 and the auxiliary pressure plate 37 remain stable when moving to the side of the first sprocket 18 and the second sprocket 19, preventing the main pressure plate 35 and the auxiliary pressure plate 37 from tilting when in the arc portion of the first chain 20.

[0062] In order to supplement the specific structure of the stone screening mechanism 28, the following features are also specifically provided:

[0063] The transmission mechanism 12 also includes two positioning racks 39, and the stone screening mechanism 28 also includes a first gear 40, a second gear 41, a third gear 42 and a fourth gear 43. The two positioning racks 39 are respectively fixedly connected to the middle of the limiting arc grooves 9 of the two side plates 8 through the tooth seats. The first gear 40 is coaxially connected to the carrier plate 34, the second gear 41 is connected to the side plate 29 and meshes with the first gear 40, the third gear 42 is connected to the side plate 29 and meshes with the second gear 41, and the fourth gear 43 is connected to the side plate 29 and meshes with the third gear 42. The first gear 40 meshes with the positioning rack 39 when it moves to the side of the stone collecting box 46. When the first chain 20 drives the carrier plate 34 to move, the carrier plate 34 drives the first gear 40 to move and makes the first gear 40 mesh with the positioning rack 39, the first gear 40 will rotate, and the first gear 40 will drive the fourth gear 43 to rotate after passing through the second gear 41 and the third gear 42 in sequence.

[0064] In order to achieve that the stone hook 32 deflects when the first gear 40 and the positioning rack 39 are meshed, the following features are also provided:

[0065] The stone screening mechanism 28 also includes a magnetic shaft 44 and a positioning pin 45. The two stone-taking hooks 32 near the side plate 29 are respectively formed with arc grooves 33 (such as Fig.10 As shown in the figure, one end of the magnetic shaft 44 is coaxially fixedly connected to the fourth gear 43, the stone taking hook 32 is connected to the other end of the magnetic shaft 44 through magnetic transmission, one end of the positioning pin 45 is fixedly connected to the side plate 29, and the other end is slidably connected to the arc groove 33, the two stone taking hooks 32 close to the side plate 29 are coaxially fixedly connected to the remaining stone taking hooks 32, and the stone taking hooks 32 are rotatably connected to the rake frame 30. When the fourth gear 43 rotates, the fourth gear 43 will drive the stone taking hook 32 to rotate through the magnetic shaft 44. When the stone taking hook 32 deflects to the point where the positioning pin 45 abuts against the groove edge of the arc groove 33, the rotation of the fourth gear 43 will continue to drive the magnetic shaft 44 to rotate. However, since the resistance is too large at this time, the continued rotation of the fourth gear 43 will cause the magnetic shaft 44 and the stone taking hook 32 to rotate relative to each other, ensuring that the stone taking hook 32 will not continue to rotate with the movement of the side plate 29.

[0066] In order to achieve that the stone hook 32 deflects when the first gear 40 and the positioning rack 39 are meshed, the following features are also provided:

[0067] The rake frame 30 is formed with a plurality of rake ribs 31 at equal intervals along the long side direction, and there is a gap between two adjacent rake ribs 31. When the stones are screened, the rake ribs 31 can ensure that the mud and straw move from the gaps between the rake ribs 31 to the rotary tillage and beating assembly 3.

[0068] The working principle of the device is that when folding, storing or unfolding, the two sub-frames 2 respectively drive the two side frames 7 to flip over. During this process, the cylinder structure can ensure the stability of its movement, and the knife shaft 4 arranged under the sub-frame 2 and the knife shaft 4 arranged under the main frame 1 are disassembled and connected through a clutch (the clutch here is the prior art, which is used to connect two knife shafts 4 or power shafts 24 that are close to each other and gradually pressed together. When the main frame 1 and the two sub-frames 2 are folded, the two knife shafts 4 or two power shafts 24 in the transmission connection state will be disconnected under the action of the clutch, and when the main frame 1 and the two sub-frames 2 are unfolded, the two knife shafts 4 or two power shafts 24 in the disconnected state will be transmission connected through the clutch. The present invention adopts a tooth clutch that can be elastically engaged and separated) to ensure that the knife shaft 4 can operate normally during operation.

[0069] When the operation is carried out, as the vehicle moves, the cutter shaft 4 will drive the main sprocket 13 connected thereto to rotate, the main sprocket 13 will drive the secondary sprocket 15 to rotate through the main chain 14, and the secondary sprocket 15 will drive the secondary gear 17 to rotate through the main gear 16. At the same time, the main gear 16 will drive the power gear 23 to rotate through the fixed gear 22, and the power gear 23 will drive the power shaft 24 connected thereto to rotate, and when the power shaft 24 rotates, the power shaft 24 arranged under the side frame 7 will drive the power shaft 24 arranged under the middle frame 6 to rotate through the clutch, thereby realizing that when the rotary tillage and beating assembly 3 is in operation, a plurality of transmission mechanisms 12 can be started synchronously, that is, a corresponding plurality of rake frames 30 can move synchronously and drive a corresponding plurality of stone hooks 32 to move.

[0070] When the main gear 16 rotates, the main gear 16 drives the power shaft 24 to rotate through the sub-gear 17. After the power shaft 24 rotates, it drives the sub-gear 17 at the other end to rotate, and then the first sprockets 18 located on the two side plates 8 will rotate. Finally, the first sprocket 18 drives the second sprocket 19 to rotate through the first chain 20. When the first chain 20 rotates, the first chain 20 drives the side plates 29 to move through the chain nails 21. After the side plates 29 move, they drive the rake frames 30 to move in a groove along the outer contour of the first chain 20. Figure 7 The second sprocket 19 rotates in a clockwise direction, and the corresponding first chain 20 rotates in a clockwise direction, that is, the plurality of rake frames 30 will also move in a clockwise groove along with the first chain 20. During the movement of the rake frames 30, the plurality of stone hooks 32 will hook up the stones in the paddy field and finally put them into the stone collecting box 46.

[0071] In the above process, the guide cone plate 11 pushes the stones facing the side plate 8 to the bottom of the rake frame 30 (the widening block 111 fixedly connected to the guide cone plate 11 can ensure that the stones will not be stuck between the two adjacent guide cone plates 11 due to the gap), so that the rake frame 30 can collect all the stones and prevent the stones from being unable to move to the bottom of the rake frame 30 and being grabbed by the stone hook 32 when they are facing the side plate 8. The gap between two adjacent rake ribs 31 will screen the size of the stones. At the same time, since some stones are irregular in shape, when these stones are hooked up by the rake frame 30 at a specific angle, these stones are stuck in the gap between two adjacent rake ribs 31. Then, these stones will move with the rake frame 30. When the stuck stones collide with the stones in the paddy field for the second time and pass through the rake frame 30, these stones will be hooked up by the next rake frame 30. Figure 3 It can be seen that the diameter of the main sprocket 13 is greater than the diameter of the secondary sprocket 15, thereby ensuring that the rotation speed of the secondary sprocket 15 is greater than the rotation speed of the main sprocket 13, thereby increasing the rotation speed of the first chain 20, thereby increasing the number of collisions between the stone-removing hooks 32 and the stones, ensuring that the stone-removing hooks 32 can continue to hook up the stones until these stones are put into the stone collection box 46.

[0072] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
