Description

Technical Field

[0001] The invention belongs to the technical field of land cultivating machines, in particular to an automatic land cultivating machine. Background Art

[0002] A tiller is a type of agricultural machinery, mainly used for soil cultivation, to complete operations such as turning over, loosening, and crushing the soil, in order to prepare suitable soil conditions for sowing crops. The existing tillers integrate tillage, sowing, and manure application, which greatly improves agricultural operation efficiency.

[0003] The patent with publication number CN114521354B discloses a reinforced rotary tiller, including a manure applying component, a rotary tillage driving component and a deep tillage component. The manure applying component is used to store manure and soil, and at the same time achieve mixing of manure and soil. The manure applying component is slidably connected to the rotary tillage driving component. This solution is set by the manure applying component. Without adding an additional power source, the slide plate is made to slide back and forth on the inclined plate of the manure storage box to control the opening and closing of the manure outlet. When the manure outlet is opened, manure flows out of the manure storage box and falls on the land, so that manure can be automatically applied during the movement of the rotary tiller. At the same time, the slide plate drives the shovel, and the shovel shovels up the soil to achieve mixing of manure and soil.

[0004] In the above scheme, the fertilizer stored in the groove is caused to flow out through the discharge port by driving the discharge roller to rotate reciprocally, and is scattered into the soil through the long holes on the guard plate. However, such operation causes the seeds to be scattered too concentratedly on the soil, resulting in a high seed density. This scheme is suitable for sowing intensive crops such as wheat, while crops such as corn are large in size. When sowing, the seeds must be sown at intervals to leave enough space for the crops to grow. Therefore, the above scheme is not suitable for sowing corn crops, which reduces the practicability of the device. For this reason, the present invention provides an automatic tillage machine. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: an automatic tilling machine described in the present invention comprises a frame, a hydraulic cylinder is hinged at the front end of the frame, a manure box, a protective cover, and a sowing mechanism are fixedly installed on the frame in sequence, a rolling roller is rotatably installed at the rear end of the frame, a discharging roller is rotatably installed in the manure box, a rotary tilling roller is rotatably installed in the protective cover, one end of the discharging roller and the rotary tilling roller are fixedly installed with pulleys, and synchronous belts are coiled on the two groups of pulleys, and the sowing mechanism comprises a storage box, the storage box is fixedly installed on the frame, three groups of feeding boxes are fixedly installed in the storage box, and a fixed column, the lower end of the fixed column is fixedly connected to the inner wall of the feeding box, and the feeding mechanism comprises a feeding box, the feeding box is fixedly installed on the frame, and the feeding box is fixedly installed in the feeding box. The feed tray, the lower end faces of the fixed column and the feed box are all fitted with the upper end face of the feed tray, the chassis, the feed tray is rotatably installed in the chassis, the lower end of the chassis is connected to the feed pipe, the lower end of the feed pipe is fixedly connected to the triangular piece, the chassis is fixedly connected to the lower end face of the storage box, the lower end of the feed tray is fixedly installed with a first bevel gear, a second bevel gear meshing with the first bevel gear, three groups of second bevel gears are fixedly sleeved on the driving rod, the driving rod is rotatably installed on the frame, a plurality of groups of discharge troughs for holding seeds are opened at equal angles on the feed tray, a fan-shaped block for covering the discharge trough is arranged in the feed box, a discharge port is opened in the chassis, and the discharge port is directly opposite to the upper end of the discharge pipe;

[0007] Since the several groups of discharge troughs on the feed tray are distributed at intervals, as the feed tray rotates, the several groups of discharge troughs allow the corn seeds to fall into the triangular pieces at intervals, so that the corn seeds sown on the land are distributed at intervals, so that there is enough space for plant growth. Secondly, corn seeds are larger in volume than seeds of intensive crops such as wheat, and multiple groups of wheat seeds can be placed in the discharge trough at a time, so that the device can also sow seeds of intensive crops such as wheat, thereby improving the practicability of the device.

[0008] Preferably, the feeding tray comprises a tray body, which is rotatably mounted in the chassis, a plurality of movable blocks movably mounted on the tray body at equal angles, two sets of springs, which are symmetrically distributed on both sides of the movable blocks, a roller rotatably mounted on the end of the movable block, a feeding box and a lower end surface of a fixed column are in contact with an upper end surface of the tray body, a discharge trough is provided on the movable block, a plurality of movable slots are provided at equal angles on the tray body, the movable blocks are plugged into the movable slots, two sets of springs are symmetrically distributed on both sides of the movable slots, the rollers are closely attached to the inner ring of the chassis, and a plurality of tooth blocks for pushing the rollers are provided at equal angles on the inner ring of the chassis;

[0009] Since there are multiple sets of tooth blocks distributed on the trajectory of the movable block rotating to the discharge port, the movable block and the corresponding discharge trough can move back and forth, which will increase the number of corn seeds contacted by the discharge trough, thereby increasing the probability of the corn seeds falling into the discharge trough. Secondly, the movable block moving back and forth will drive the corn seeds piled together, so that the corn seeds piled together will move relative to each other, which is conducive to the corn seeds falling into the discharge trough. Therefore, the coordinated setting of the movable block, spring, roller and tooth block reduces the risk of the discharge trough failing to receive the corn seeds, thereby improving the sowing rate of corn seeds and the uniformity of sowing.

[0010] Preferably, the feeding tray also includes a sealing tube, which is fixedly installed at the middle part of the upper end surface of the tray body, and the sealing tube is rotatably connected to the lower port of the fixed column, and a plurality of groups of second through holes are opened at equal angles on the inner circle of the sealing tube, and an air pipe is opened, and the air pipe is located in the movable slot, and one end of the air pipe is connected to the second through hole, and a first through hole is opened on the movable block, and the other end of the air pipe is connected to the first through hole, and the sowing mechanism also includes a multi-way pipeline, and three groups of air outlet ends on the multi-way pipeline are respectively connected to the upper ports of the three groups of fixed columns, and one group of air inlet ends on the multi-way pipeline is connected to the vacuum pump, and a sealing rubber plate is fixedly installed in the lower port of the fixed column, and the lower end of the sealing rubber plate extends into the sealing tube, and the lower end of the sealing rubber plate is close to the inner wall of the sealing tube;

[0011] By making the discharge trough generate suction, corn seeds can fall into the discharge trough more easily, thereby further improving the sowing rate and uniformity of the corn seeds.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. Since the several groups of discharge troughs on the feed tray are distributed at intervals, as the feed tray rotates, the several groups of discharge troughs allow the corn seeds to fall into the triangular pieces at intervals, so that the corn seeds sown on the land are distributed at intervals, so that there is enough space for plant growth. Secondly, the volume of corn seeds is larger than that of seeds of intensive crops such as wheat. Multiple groups of wheat seeds can be placed in the discharge trough at one time, so that the device can also sow seeds of intensive crops such as wheat, thereby improving the practicability of the device.

[0014] 2. The movable block moves along the movable slot toward the center of the feed tray, and the movable block compresses the two sets of springs until the roller is staggered from the tooth block. Under the action of the spring rebound force, the movable block moves back. Since there are multiple sets of tooth blocks distributed on the trajectory of the movable block rotating to the discharge port, the movable block and the corresponding discharge trough move back and forth, which will increase the number of corn seeds contacted by the discharge trough, thereby increasing the probability of corn seeds falling into the discharge trough. Secondly, the reciprocating movable block will drive the corn seeds piled together, so that the corn seeds piled together move relative to each other, which is conducive to the corn seeds falling into the discharge trough. Therefore, the coordinated setting of the movable block, spring, roller and tooth block reduces the risk that the discharge trough cannot receive corn seeds, thereby improving the sowing rate of corn seeds and the uniformity of sowing.

[0015] 3. Start the vacuum pump, which causes the multi-channel pipe to generate suction on the fixed column. Since the interior of the fixed column, the interior of the sealing tube, the second through hole, the air pipe, and the first through hole are connected, the air in the discharge trough is sucked away by the first through hole, so that the discharge trough generates suction on the corn seeds accumulated in the feed box, so that the corn is sucked into the discharge trough. When the corn seeds in the discharge trough move to the discharge port, the second through hole corresponding to the discharge trough is blocked by the sealing rubber sheet, and the discharge trough will release the suction on the corn seeds, so that the corn seeds are separated from the discharge trough. By generating suction in the discharge trough, the corn seeds are easier to fall into the discharge trough, which further improves the sowing rate and sowing uniformity of the corn seeds.

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0027] Embodiment 1: Figures 1 to 4As shown, an automatic tilling machine described in an embodiment of the present invention includes a frame 1, a hydraulic cylinder 2 is hinged at the front end of the frame 1, a manure box 3, a protective cover 4, and a sowing mechanism 5 are fixedly installed on the frame 1 in sequence, a rolling roller 6 is rotatably installed at the rear end of the frame 1, a discharging roller 8 is rotatably installed in the manure box 3, a rotary tilling roller 7 is rotatably installed in the protective cover 4, one end of the discharging roller 8 and the rotary tilling roller 7 are fixedly installed with a pulley 9, and a synchronous belt 10 is coiled on the two groups of pulleys 9, and the sowing mechanism 5 includes a storage box 501, the storage box 501 is fixedly installed on the frame 1, three groups of feeding boxes 502 are fixedly installed in the storage box 501, a fixed column 503, the lower end of the fixed column 503 is fixedly connected to the inner wall of the feeding box 502, and a feeding tray 504, and the lower end surface of the fixed column 503 and the feeding box 502 are both in contact with the feeding tray 5 04, chassis 505, feeding tray 504 is rotatably installed in chassis 505, the lower end of chassis 505 is connected to feeding pipe 507, the lower end of feeding pipe 507 is fixedly connected to triangular piece 508, chassis 505 is fixedly connected to the lower end surface of storage box 501, the lower end of feeding tray 504 is fixedly installed with first bevel gear 506, the second bevel gear 509 meshing with the first bevel gear 506, three groups of second bevel gears 509 are fixedly sleeved on driving rod 510, driving rod 510 is rotatably installed on frame 1, a plurality of groups of feeding troughs 51 for holding seeds are provided at equal angles on feeding tray 504, a fan-shaped block 5021 for shielding feeding trough 51 is provided in feeding box 502, a feeding port 5051 is provided in chassis 505, and feeding port 5051 is directly opposite to the upper end of feeding tube 507.

[0028] Specifically, only one corn seed can be placed in the discharge trough 51 at a time, and the rotary tillage roller 7 is driven to rotate by the hydraulic gear pump 11. In the initial state, the entire tilling machine does not contact the ground. The head end of the frame 1 is hinged to the rear of the tractor, and the cylinder body of the hydraulic cylinder 2 is hinged to the rear of the tractor. When the land is cultivated, the sown corn seeds and manure are added to the manure box 3 and the storage box 501 respectively, and the corn seeds will fall into the feed box 502 along the inner cavity of the storage box 501. The frame 1 is pushed by the hydraulic cylinder 2 to make the frame 1 flip downward, so that the rotary tillage roller 7 and the rolling roller 6 generate an extrusion force with the ground, and the three sets of triangular pieces 508 are inserted into the soil. The tilling machine is dragged by the tractor, and the rotary tillage roller 7 is driven to rotate by the hydraulic gear pump 11. The rotating rotary tillage roller 7 breaks the soil, and the rotary tillage roller 7 drives the corresponding pulley 9 to rotate. The pulley 9 is connected to the synchronous belt 10. Another set of pulleys 9 is made to rotate together with the discharging roller 8, and the rotating discharging roller 8 spreads the manure in the manure box 3 onto the land. During the process of the rotary tillage roller 7 breaking the soil, the broken soil is mixed with the manure. When the storage box 501 moves to the top of the soil after rotary tillage along with the mobile tilling machine, the driving rod 510 is driven by the motor to rotate, and the rotating driving rod 510 drives the three sets of second bevel gears 509 to rotate, and the second bevel gear 509 drives the first bevel gear 506 to rotate together with the feeding tray 504. As the feeding tray 504 rotates, the corn seeds in the feeding box 502 will fall into the discharge trough 51 on the feeding tray 504, and the corn seeds together with the corresponding discharge trough 51 will move along with the feeding tray 504 toward the discharge port 5051 in the chassis 505. When the corn seeds move to the discharge port 5051, the upper end of the corresponding discharge trough 51 is blocked by the lower end surface of the fan-shaped block 5021, and under the action of gravity, the corn seeds will automatically break away from the discharge trough 51, so that the corn seeds fall into the discharge pipe 507, and then the corn seeds will fall into the triangular piece 508 along the inner cavity of the discharge pipe 507. Since the triangular piece 508 extends into the broken soil and moves, the corn seeds will fall directly into the soil. Since the triangular piece 508 has a blocking effect on the soil on both sides, after the corn seeds break away from the triangular piece 508, the soil on both sides will directly bury the corn seeds. At the same time, the rolling roller 6 at the rear rolls the soil buried with the corn seeds to compact the soil. The above operation is repeated in a cycle to achieve the sowing of corn seeds. Compared with the prior art,

[0029] Since the several groups of discharge troughs 51 on the feed tray 504 are distributed at intervals, as the feed tray 504 rotates, the several groups of discharge troughs 51 allow the corn seeds to fall into the triangular pieces 508 at intervals, so that the corn seeds sown on the land are distributed at intervals, so that there is enough space for the plants to grow. Secondly, the volume of corn seeds is larger than that of seeds of intensive crops such as wheat. Multiple groups of wheat seeds can be placed in the discharge trough 51 at a time, so that the device can also sow seeds of intensive crops such as wheat, thereby improving the practicality of the device.

[0030] Embodiment 2: Figures 5 to 7 As shown in the comparative example 1, another embodiment of the present invention is as follows: the feeding tray 504 includes a tray body 5041, the tray body 5041 is rotatably mounted in the chassis 505, a plurality of groups of movable blocks 5043 are movably mounted on the tray body 5041 at equal angles, two groups of springs 5044, the two groups of springs 5044 are symmetrically distributed on both sides of the movable blocks 5043, a roller 5045 rotatably mounted at the end of the movable blocks 5043, and a feed box 502 and a fixed column 503 are connected. The lower end surface fits the upper end surface of the disk body 5041, the discharge trough 51 is opened on the movable block 5043, a plurality of groups of movable slots 5042 are opened at equal angles on the disk body 5041, the movable block 5043 is inserted into the movable slots 5042, two groups of springs 5044 are symmetrically distributed on both sides of the movable slots 5042, the roller 5045 is close to the inner ring of the chassis 505, and a plurality of groups of tooth blocks 5052 for pushing the roller 5045 are arranged at equal angles on the inner ring of the chassis 505.

[0031] Specifically, during the rotation of the feeding tray 504, since the corn seeds are piled up in the feeding box 502, the corn seeds will be squeezed against each other, resulting in a large friction force between the corn seeds. The friction force will hinder the corn seeds from falling into the discharge trough 51, which not only increases the risk that the discharge trough 51 cannot receive the corn seeds, resulting in a reduced sowing rate of the corn seeds, but also makes the corn seeds sown on the land unevenly distributed. Therefore, during the rotation of the feeding tray 504, several groups of movable blocks 5043 will rotate with the disk body 5041, and at the same time, the roller 5045 at the end of the movable block 5043 will roll against the inner ring of the chassis 505. Since the inner ring of the chassis 505 is provided with a tooth block 5052, the rolling roller 5045 will be squeezed by the tooth block 5052, causing the movable block 5043 to move along the movable slot 5042 toward the center of the feeding tray 504, and the movable block 5043 presses The two sets of springs 5044 are compressed until the roller 5045 is offset from the tooth block 5052. Under the action of the rebound force of the spring 5044, the movable block 5043 moves back. Since the movable block 5043 rotates to the trajectory of the discharge port 5051 and there are multiple sets of tooth blocks 5052, the movable block 5043 and the corresponding discharge trough 51 are moved back and forth. This will increase the number of corn seeds contacted by the discharge trough 51, thereby increasing the probability of the corn seeds falling into the discharge trough 51. Secondly, the movable block 5043 that moves back and forth will drive the corn seeds piled together, so that the corn seeds piled together move relative to each other, which is conducive to the corn seeds falling into the discharge trough 51. Therefore, the coordinated setting of the movable block 5043, the spring 5044, the roller 5045 and the tooth block 5052 reduces the risk that the discharge trough 51 cannot receive the corn seeds, thereby improving the sowing rate of the corn seeds and the uniformity of sowing.

[0032] like Figure 1and Figure 8 As shown, the feed tray 504 also includes a sealing tube 5046, which is fixedly installed at the middle of the upper end surface of the tray body 5041, and the sealing tube 5046 is rotatably connected to the lower end of the fixed column 503. The inner circle of the sealing tube 5046 is provided with a plurality of groups of second through holes 461 at equal angles, and an air pipe 5047, which is located in the movable slot 5042, and one end of the air pipe 5047 is connected to the second through hole 461. The movable block 5043 is provided with a first through hole 431. The other end of the air pipe 5047 is connected to the first through hole 431, and the sowing mechanism 5 also includes a multi-way pipe 511. The three groups of air outlet ends on the multi-way pipe 511 are respectively connected to the upper ports of the three groups of fixed columns 503, and one group of air inlet ends on the multi-way pipe 511 is connected to the vacuum pump 512. A sealing rubber plate 5031 is fixedly installed in the lower port of the fixed column 503, and the lower end of the sealing rubber plate 5031 extends into the sealing tube 5046, and the lower end of the sealing rubber plate 5031 is close to the inner wall of the sealing tube 5046.

[0033] Specifically, the air pipe 5047 is a rubber tube and is spiral-shaped, so that the air pipe 5047 has elasticity. During the rotation of the feed tray 504, the vacuum pump 512 is started at the same time, and the vacuum pump 512 causes the multi-channel pipe 511 to generate suction force on the fixed column 503. Since the inside of the fixed column 503, the inside of the sealing tube 5046, the second through hole 461, the air pipe 5047, and the first through hole 431 are connected, the air in the discharge trough 51 is sucked away by the first through hole 431, so that the discharge trough 51 is close to the accumulation Suction is generated on the corn seeds in the feed box 502, so that the corn is sucked into the discharge trough 51. When the corn seeds in the discharge trough 51 move to the discharge port 5051, the second through hole 461 corresponding to the discharge trough 51 is blocked by the sealing rubber plate 5031, and the discharge trough 51 will release the suction on the corn seeds, so that the corn seeds will be separated from the discharge trough 51. By generating suction in the discharge trough 51, the corn seeds are easier to fall into the discharge trough 51, thereby further improving the sowing rate and uniformity of the corn seeds.

[0034] Working principle: the corn seeds and manure to be sown are added to the manure box 3 and the storage box 501 respectively, and the corn seeds will fall into the feeding box 502 along the inner cavity of the storage box 501, and the frame 1 is pushed by the hydraulic cylinder 2 to make the frame 1 flip downward, so that the rotary roller 7 and the rolling roller 6 generate extrusion force with the ground, and the three sets of triangular pieces 508 are inserted into the soil. The tiller is dragged by a tractor, and the rotary roller 7 is driven to rotate by the hydraulic gear pump 11. The rotating rotary roller 7 breaks the soil, and the rotary roller 7 drives the corresponding pulley 9 to rotate, and the pulley 9 is driven by the synchronous belt 10 Another set of pulleys 9 is made to rotate together with the discharging roller 8, and the rotating discharging roller 8 spreads the manure in the manure box 3 onto the land. During the process of the rotary tillage roller 7 breaking the soil, the broken soil is mixed with the manure. When the storage box 501 moves to the top of the soil after rotary tillage along with the mobile tilling machine, the driving rod 510 is driven by the motor to rotate, and the rotating driving rod 510 drives the three sets of second bevel gears 509 to rotate, and the second bevel gear 509 drives the first bevel gear 506 to rotate together with the feeding tray 504. As the feeding tray 504 rotates, the corn seeds in the feeding box 502 will fall into the discharge trough 51 on the feeding tray 504, and the corn seeds together with the corresponding discharge trough 51 will follow the feeding tray 504 to the discharge port 505 in the chassis 505. 1. When the corn seeds move to the discharge port 5051, the upper end of the corresponding discharge trough 51 is blocked by the lower end surface of the fan-shaped block 5021, and under the action of gravity, the corn seeds will automatically break away from the discharge trough 51, so that the corn seeds fall into the discharge pipe 507, and then the corn seeds will fall into the triangular piece 508 along the inner cavity of the discharge pipe 507. Since the triangular piece 508 extends into the broken soil and moves, the corn seeds will directly fall into the soil. Since the triangular piece 508 has a blocking effect on the soil on both sides, after the corn seeds break away from the triangular piece 508, the soil on both sides will directly bury the corn seeds. At the same time, the rolling roller 6 at the rear rolls the soil buried with the corn seeds to compact the soil. The above operation is repeated in a cycle to achieve the sowing of corn seeds.

[0035] During the rotation of the feeding tray 504, several groups of movable blocks 5043 will rotate together with the tray body 5041, and at the same time, the rollers 5045 at the ends of the movable blocks 5043 will roll against the inner ring of the chassis 505. Since the inner ring of the chassis 505 is provided with tooth blocks 5052, the rolling rollers 5045 will be squeezed by the tooth blocks 5052, so that the movable blocks 5043 move along the movable slots 5042 toward the center of the feeding tray 504, and the movable blocks 5043 compress the two groups of springs 5044 until the rollers 5045 stagger the tooth blocks 5052. Under the action of the rebound force, the movable block 5043 moves back. Since there are multiple sets of tooth blocks 5052 distributed on the trajectory of the movable block 5043 rotating to the discharge port 5051, the movable block 5043 and the corresponding discharge trough 51 move back and forth, which will increase the number of corn seeds contacted by the discharge trough 51, thereby increasing the probability of corn seeds falling into the discharge trough 51. Secondly, the reciprocating movable block 5043 will drive the corn seeds piled together, so that the corn seeds piled together move relative to each other, which is conducive to the corn seeds falling into the discharge trough 51;

[0036] During the rotation of the feeding disc 504, the vacuum pump 512 is started at the same time. The vacuum pump 512 causes the multi-channel pipe 511 to generate suction on the fixed column 503. Since the interior of the fixed column 503, the interior of the sealing tube 5046, the second through hole 461, the air pipe 5047, and the first through hole 431 are connected, the air in the discharge trough 51 is sucked away by the first through hole 431, so that the discharge trough 51 generates suction on the corn seeds accumulated in the feeding box 502, so that the corn is sucked into the discharge trough 51. When the corn seeds in the discharge trough 51 move to the discharge port 5051, the second through hole 461 corresponding to the discharge trough 51 is blocked by the sealing rubber sheet 5031, and the discharge trough 51 will release the suction on the corn seeds, so that the corn seeds are separated from the discharge trough 51.

[0037] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
