Description

Technical Field

[0002] Agricultural tillage is an important farmland management measure. Tillage can break up the soil compaction layer, increase soil looseness, optimize soil structure, and facilitate the extension and development of crop roots. Agricultural machinery is generally used for tillage operations. Mechanical tillage can greatly improve work efficiency. Compared with traditional manual tillage, machinery can complete large-area soil renovation work in a short time, thereby saving a lot of manpower and time.

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical agricultural machinery soil turning device in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] like Figure 1-Figure 5 As shown, the present invention provides: an agricultural mechanical soil turning device, comprising a frame 1, a transmission mechanism is provided on the upper surface of the frame 1, a rotating frame 11 is rotatably connected to one side of the frame 1, a moving wheel 32 is rotatably connected to one side of the rotating frame 11 inside the frame 1, and a soil turning mechanism for breaking soil blocks is provided inside the rotating frame 11;

[0050] The soil turning mechanism includes a soil turning cylinder 2 rotatably connected between the rotating frames 11, one end of the soil turning cylinder 2 is connected to the output end of the transmission mechanism, a plurality of first soil turning plates 21 are fixedly connected to the surface of the soil turning cylinder 2, a plurality of through holes 24 are opened on the outer wall of the soil turning cylinder 2, and a second soil turning plate 22 is slidably connected inside the through holes 24, a soil collecting frame 27 is fixedly connected between the two rotating frames 11 and located on one side of the soil turning cylinder 2, a plurality of second tooth blocks 271 are fixedly connected inside the soil collecting frame 27, and the second tooth blocks 271 and the first soil turning plates 21 are meshed with each other;

[0051] The first tilling plate 21 and the second tilling plate 22 rotate along with the tilling cylinder 2 and push the block soil to the second tooth block 271 in the soil collecting frame 27 for extrusion and crushing.

[0052] Specifically, in the prior art, a soil turning device is generally driven to rotate to turn the soil. When the soil texture is too sticky, a large amount of soil blocks will be generated after the soil turning operation. The soil blocks will hinder the gas exchange and water penetration in the soil, resulting in poor soil ventilation and water permeability, which will reduce the root respiration and water absorption rate of crops, thereby causing root diseases and affecting the normal growth of crops.

[0053] In order to solve the above problems, its working principle is as follows: the user holds the pull rod on the frame 1 and pulls the frame 1 to move, turns on the driving mechanism, and the driving mechanism can rotate the tilling cylinder 2 synchronously, and then drives the rotating frame 11 to rotate, and the rotating frame 11 drives the tilling cylinder 2 to contact with the soil, and the first tilling plate 21 and the second tilling plate 22 on the surface of the tilling cylinder 2 are attached to each other and contact with the soil, and then the tilling cylinder 2 drives the first tilling plate 21 and the second tilling plate 22 to rotate, and the first tilling plate 21 and the second tilling plate 22 are in contact with the soil and turn the soil. When there is lumpy soil in the turned soil, the first tilling plate 21 and the second tilling plate 22 are turned over. The plate 21 and the second tilling plate 22 drive the block soil to rotate synchronously, and the block soil is pushed into the soil collecting frame 27, and then the block soil is pushed to the second tooth block 271, and the block soil is crushed through the gap between the second tooth blocks 271. When the second tilling plate 22 moves to the second tooth block 271, the second tilling plate 22 is driven to slide into the inside of the through hole 24, so that the second tilling plate 22 is received into the inside of the tilling cylinder 2, and at the same time, the second tooth block 271 and the first tilling plate 21 are meshed with each other and pass through the second tooth block 271, at this time, the block soil can be crushed during the soil tilling operation;

[0054] The device can break up the soil in bulk, making it more finely divided, which is beneficial to subsequent sowing, fertilization and crop growth, and avoids the compaction of the soil, which results in a decrease in soil air permeability and water penetration.

[0055] like Figure 2 As shown, the transmission mechanism includes a motor 3 fixedly connected to the upper surface of the frame 1, and the first pulley 31 is fixedly connected to the rotating shaft surface between the output end of the motor 3 and the moving wheel 32, a rotating rod 34 is fixedly connected to one side of the frame 1 and located between the moving wheel 32 and the rotating frame 11, and the rotating shaft surface between the rotating rod 34 and the moving wheel 32 is fixedly connected to the second pulley 33, and the surface of the rotating rod 34 and one end of the tilling barrel 2 are fixedly connected to the third pulley 35, and the two first pulleys 31, the second pulleys 33 and the third pulley 35 are respectively connected by belt transmission.

[0056] Specifically, the motor 3 is turned on to work, and the motor 3 drives the first pulley 31 at its output end to rotate synchronously, and the first pulley 31 drives the first pulley 31 on the surface of the rotating shaft of the moving wheel 32 to rotate synchronously through the belt inside it, so that the moving wheel 32 can rotate, thereby facilitating the staff to drive the frame 1 to move. At the same time, the rotating shaft of the moving wheel 32 drives the second pulley 33 to rotate, and the second pulley 33 drives the second pulley 33 on the surface of the rotating rod 34 to rotate synchronously through the internal belt. The rotation of the rotating rod 34 drives the third pulley 35 on its surface to rotate, and the third pulley 35 drives the third pulleys 35 at both ends of the soil-turning drum 2 to rotate synchronously through the belt inside it, which can drive the soil-turning drum 2 to rotate synchronously, and the soil-turning operation can be performed.

[0057] like Figure 6-Figure 11 As shown, both sides of the frame 1 are fixedly connected with a fixing frame 12, and a limiting rod 23 is fixedly connected between the two fixing frames 12. The limiting rod 23 is located on the inner side of the tilling barrel 2, and a slide groove 231 is provided on the surface of the limiting rod 23. One side of several second tilling plates 22 is fixedly connected with a first connecting plate 25, and one side of the first connecting plate 25 is rotatably connected with a first pulley 251, and one side of the first pulley 251 is in contact with the surface of the limiting rod 23. Both ends of the first connecting plate 25 are provided with a spring telescopic rod 252, and the fixed end of the spring telescopic rod 252 is fixedly connected to the inner wall of the tilling barrel 2, and the movable end of the spring telescopic rod 252 is fixedly connected to both ends of the first connecting plate 25.

[0058] Specifically, when the second tillage plate 22 rotates synchronously with the tillage barrel 2, the second tillage plate 22 drives the first connecting plate 25 to rotate synchronously, and the first connecting plate 25 drives the first pulley 251 to rotate around the surface of the limiting rod 23. When the first pulley 251 rotates to the bottom of the slide groove 231 of the limiting plate, the first pulley 251 drives the first connecting plate 25 to slide toward the inner side of the slide groove 231, so that the first connecting plate 25 stretches the spring telescopic rod 252, so that the first connecting plate 25 drives multiple second tillage plates 22 to move in the through hole. 24 slides inside, the second tillage plate 22 slides toward the inside of the tillage cylinder 2. At this time, the second tillage plate 22 is stored in the through hole 24, and the tillage cylinder 2 can drive the first tooth block 232 to pass through the second tooth block 271, so as to realize the automatic storage operation of the second tillage plate 22. When the first pulley 251 slides out of the slide groove 231 and moves to the surface of the limit rod 23, the second tillage plate 22 is reset, so as to realize the automatic reset of the second tillage plate 22 to cooperate with the first tillage plate 21 for subsequent tillage operations.

[0059] like Figure 12-13As shown, a piston 222 is fixedly connected to the inside of the second tillage plate 22, a vibration plate 221 is fixedly connected to the upper surface of the piston 222, a moving rod 223 is fixedly connected to the lower surface of the piston 222, a first spring 225 is fixedly connected between the surface of the moving rod 223 and the inner wall of the second tillage plate 22, a plurality of first tooth blocks 232 are fixedly connected to the outer wall of the limit rod 23, a protrusion plate 224 is slidably connected to the inner lower surface of the second tillage plate 22, and the upper surface of the protrusion plate 224 Fitting with one end of the moving rod 223, one side of the protrusion plate 224 is fixedly connected with the second connecting plate 26, one end of the second connecting plate 26 is rotatably connected with the second pulley 261, one end of the second pulley 261 is fitted with the limit rod 23, and the inside of the second connecting plate 26 is slidably connected with a positioning rod 262, one end of the positioning rod 262 is fixedly connected with a third spring 263 between one end of the positioning rod 262 and one side of the second connecting plate 26, and one end of the positioning rod 262 is fixedly connected to one end of the first connecting plate 25.

[0060] Specifically, when the soil is relatively moist and has a certain degree of adhesion, during the soil turning operation of the second soil turning plate 22, the soil may adhere to the surface of the second soil turning plate 22, causing the weight of the second soil turning plate 22 to increase. When the weight of the second soil turning plate 22 and the soil is greater than the return force of the spring telescopic rod 252, it is difficult for the second soil turning plate 22 to return to the inside of the through hole 24, and the second soil turning plate 22 will be limited by the second tooth block 271, making it difficult for the soil turning operation to operate normally, thereby causing the problem of reduced soil turning efficiency.

[0061] In order to solve the above problem, its working principle is as follows: when the second tillage plate 22 rotates synchronously with the tillage drum 2, the second tillage plate 22 drives the second pulley 261 on one side of the second connecting plate 26 to rotate synchronously around the surface of the limiting rod 23. When the second pulley 261 moves to the first tooth block 232, the first tillage plate 21 and the second tillage plate 22 are in contact with the soil and turn the soil. When the second pulley 261 moves from the surface of the limiting rod 23 to the surface of the second tooth block 271, the second pulley 261 is squeezed and pushes the first connecting plate 25 to slide on the surface of the positioning rod 262. The first connecting plate 25 stretches the third spring 263 and drives the protrusion plate 224 to move synchronously. The protrusion plate 224 slides toward the inner side of the second tillage plate 22, and the protrusion plate 224 is pressed against the One end of the moving rod 223 is squeezed, so that the moving rod 223 slides toward the outside of the second tillage plate 22, and the moving rod 223 drives the vibration plate 221 above the piston 222 to slide synchronously toward the outside. When the second pulley 261 slides from the surface of the first tooth block 232 to the surface of the limit rod 23, the first connecting plate 25 is reset by the third spring 263, so that the protrusion plate 224 is reset. At this time, the first spring 225 drives the moving rod 223 to reset quickly, and the moving rod 223 drives the vibration plate 221 to slide toward the inside of the second tillage plate 22. Repeat the above operation to drive the vibration plate 221 to reciprocate. At this time, the adhered soil on the surface of the vibration plate 221 follows the reciprocating vibration of the vibration plate 221, and the vibration plate 221 can shake off the soil adhered to its surface.

[0062] The device can shake off the soil adhered to the surface of the second turning plate 22 through the reciprocating motion of the vibration plate 221, thereby preventing the soil from adhering to the surface of the second turning plate 22, so that the weight of the second turning plate 22 increases and is greater than the reset capacity of the spring telescopic rod 252, resulting in the difficulty in resetting the second turning plate 22, thereby making it difficult to continue to crush the soil through the second tooth block 271, resulting in a decrease in the turning efficiency. At the same time, when the vibration plate 221 vibrates reciprocatingly, it can also shatter the soil pushed to the second tooth block 271, thereby accelerating the crushing efficiency.

[0063] like Fig. 9 As shown, the length of the first tooth block 232 is smaller than the length of the sliding groove 231 , and the distance between the two second pulleys 261 is smaller than the distance between the two first pulleys 251 .

[0064] Specifically, when the first tooth block 232 contacts the second pulley 261, the first pulley 251 does not contact the first tooth block 232. At this time, the normal soil turning operation of the first and second soil turning plates 21 and 22 can be maintained, and the surface soil of the second soil turning plate 22 can also be shaken off.

[0065] like Figure 12-14As shown, the upper surface of the vibration plate 221 is slidably connected to an exhaust frame 228, and the lower surface of the exhaust frame 228 is slidably connected to an exhaust one-way valve pipe 226. The exhaust one-way valve pipe 226 is fixedly connected to the inner wall of the second turning plate 22, and one end of the exhaust one-way valve is opened below the piston 222. The inner wall of the second turning plate 22 is fixedly connected to an intake one-way valve pipe 227, and the intake one-way valve pipe 227 is located on one side of the exhaust one-way valve, and one end of the intake one-way valve pipe 227 is opened on the inner side of the turning cylinder 2.

[0066] Specifically, during the soil turning operation, soil particles may accumulate on the surface of the second turning plate 22 or in the gap of the through hole 24. When the second turning plate 22 is reset, the soil particles accumulated between its surface and the gap of the through hole 24 will increase the friction resistance, affecting the reset of the second turning plate 22 and causing the reset of the second turning plate 22 to get stuck.

[0067] In order to solve the above problems, when the second tillage plate 22 is outside the through hole 24, the exhaust frame 228 is at the connection between the second tillage plate 22 and the through hole 24, and the exhaust frame 228 blocks the gap between the through hole 24 and the second tillage plate 22. At the same time, when the vibration plate 221 reciprocates, the vibration plate 221 drives the piston 222 to reciprocate inside the second tillage plate 22. When the piston 222 moves downward, the piston 222 squeezes the air inside the second tillage plate 22 and opens the exhaust one-way valve pipe 226, so that the air flows to the inside of the exhaust frame 228 through the exhaust one-way valve pipe 226, and then the clean air flow is discharged through the exhaust frame 228. The clean air flow can clean the soil particles on the surface of the vibration plate 221. When the piston 222 moves upward inside the second tillage plate 22, the air intake one-way valve pipe 227 opens, so that the air on the inner wall of the tillage barrel 2 flows into the inside of the second tillage plate 22 for subsequent use.

[0068] This device can blow the surface of the vibration plate 221 to prevent soil particles from adhering to the surface of the vibration plate 221. It can also prevent soil particles from being blocked in the gap between the second tillage plate 22 and the through hole 24, and soil particles from following the vibration plate 221 to move to the through hole 24, and impurities from being stuck in the through hole 24, making it difficult to reset the second tillage plate 22.

[0069] like Fig.14 As shown, a second spring 229 is fixedly connected between the exhaust frame 228 and the upper surface of the vibration plate 221 . The exhaust frame 228 is shaped as an isosceles trapezoid, and arc chamfers are provided on both sides of the through hole 24 .

[0070] Specifically, when the second earth-turning plate 22 is stored, the second earth-turning plate 22 drives the vibration plate 221 to move synchronously, and the vibration plate 221 drives the exhaust frame 228 to slide synchronously. The exhaust frame 228 is squeezed by the arc chamfer on one side of the through hole 24, so that the exhaust frame 228 squeezes the second spring 229 to be stored inside the vibration plate 221, which can facilitate the storage operation of the second earth-turning plate 22 through the through hole 24.

[0071] Working principle: the user holds the pull rod on the frame 1 and pulls the frame 1 to move, turns on the motor 3, and the motor 3 drives the first pulley 31 at its output end to rotate synchronously. The first pulley 31 drives the first pulley 31 on the surface of the rotating shaft of the moving wheel 32 to rotate synchronously through the belt inside it, so that the moving wheel 32 can rotate, so that it is convenient for the staff to drive the frame 1 to move. At the same time, the rotating shaft of the moving wheel 32 drives the second pulley 33 to rotate. The second pulley 33 drives the second pulley 33 on the surface of the rotating rod 34 to rotate synchronously through the internal belt. The rotation of the rotating rod 34 drives the third pulley 35 on its surface to rotate. The third pulley 35 drives the third pulleys 35 at both ends of the soil turning barrel 2 to rotate synchronously through the internal belt.

[0072] Then the rotating frame 11 is driven to rotate, and the rotating frame 11 drives the tilling cylinder 2 to contact with the soil, and the first tilling plate 21 and the second tilling plate 22 on the surface of the tilling cylinder 2 are attached to each other and contact with the soil, and then the tilling cylinder 2 drives the first tilling plate 21 and the second tilling plate 22 to rotate, and the first tilling plate 21 and the second tilling plate 22 contact with the soil and turn the soil, when there is block soil in the turned soil, the first tilling plate 21 and the second tilling plate 22 drive the block soil to rotate synchronously, and the block soil is pushed into the soil collecting frame 27, and then the block soil is pushed to the second tooth block 271, and the block soil is broken through the gap between the second tooth blocks 271;

[0073] When the second tillage plate 22 moves to the second tooth block 271, the second tillage plate 22 drives the first connecting plate 25 to rotate synchronously, and the first connecting plate 25 drives the first pulley 251 to rotate around the surface of the limiting rod 23. The first pulley 251 rotates to the bottom of the slide groove 231 of the limiting plate, and the first pulley 251 drives the first connecting plate 25 to slide toward the inner side of the slide groove 231, so that the first connecting plate 25 stretches the spring telescopic rod 252, so that the first connecting plate 25 drives multiple second tillage plates 22 to move in the through hole 24. The second tillage plate 22 slides inside the tillage cylinder 2, and the second tillage plate 22 slides toward the inside of the tillage cylinder 2. At this time, the second tillage plate 22 is stored in the through hole 24, and the tillage cylinder 2 can drive the first tooth block 232 to pass through the second tooth block 271, so as to realize the automatic storage operation of the second tillage plate 22. When the first pulley 251 slides out of the slide groove 231 and moves to the surface of the limit rod 23, the second tillage plate 22 is reset, so as to realize the automatic reset of the second tillage plate 22 to cooperate with the first tillage plate 21 for subsequent tillage operation;

[0074] The second tillage plate 22 rotates synchronously with the tillage barrel 2, and the second tillage plate 22 drives the second pulley 261 on one side of the second connecting plate 26 to rotate synchronously around the surface of the limiting rod 23. When the second pulley 261 moves to the first tooth block 232, the first tillage plate 21 and the second tillage plate 22 are in contact with the soil and perform a tillage operation on the soil. When the second pulley 261 moves from the surface of the limiting rod 23 to the surface of the second tooth block 271, the second pulley 261 is squeezed and pushes the first connecting plate 25 to slide on the surface of the positioning rod 262. The first connecting plate 25 stretches the third spring 263 and drives the protrusion plate 224 to move synchronously. The protrusion plate 224 slides toward the inner side of the second tillage plate 22, and at the same time, the protrusion plate 224 pushes one end of the moving rod 223. The moving rod 223 is squeezed to slide toward the outside of the second tillage plate 22, and the moving rod 223 drives the vibration plate 221 above the piston 222 to slide toward the outside synchronously. When the second pulley 261 slides from the surface of the first tooth block 232 to the surface of the limit rod 23, the first connecting plate 25 is reset by the third spring 263, so that the protrusion plate 224 is reset. At this time, the first spring 225 drives the moving rod 223 to reset quickly, and the moving rod 223 drives the vibration plate 221 to slide toward the inside of the second tillage plate 22. Repeat the above operation to drive the vibration plate 221 to reciprocate. At this time, the adhered soil on the surface of the vibration plate 221 follows the reciprocating vibration of the vibration plate 221, and the vibration plate 221 can shake off the soil adhered to its surface.

[0075] When the second tillage plate 22 is outside the through hole 24, the exhaust frame 228 is at the connection between the second tillage plate 22 and the through hole 24, and the exhaust frame 228 blocks the gap between the through hole 24 and the second tillage plate 22. At the same time, when the vibration plate 221 reciprocates, the vibration plate 221 drives the piston 222 to reciprocate inside the second tillage plate 22. When the piston 222 moves downward, the piston 222 squeezes the air inside the second tillage plate 22 and opens the exhaust one-way valve pipe 226, so that the air flows through the exhaust one-way valve pipe 226 to the inside of the exhaust frame 228, and then the clean air flow is discharged through the exhaust frame 228. The clean air flow can clean the soil particles on the surface of the vibration plate 221. When the piston 222 moves upward inside the second tillage plate 22, the intake one-way valve pipe 227 opens, so that the air on the inner wall of the tillage barrel 2 flows into the inside of the second tillage plate 22 for subsequent use.
