Description

TECHNICAL FIELD

[0001] The application belongs to the field of straw returning to field equipment, and particularly relates to a whole-plant straw non-smashing deep returning to field burying device. BACKGROUND

[0002] A patent with the publication number CN114431085A discloses a corn alternate rotation planting method. The method can reduce water evaporation and retain soil moisture by gathering straw and covering soil to form a soil conservation zone. The method can effectively alleviate the water shortage problem of corn growth period and promote corn yield. At the same time, the straw is deep returned to field in the blank zone on both sides. After several years of rotation, the whole field can be returned to field, which can effectively maintain soil fertility and realize sustainable agricultural development.

[0003] The method also discloses a "straw concentrated side burying returning to field machine" needed in the straw returning to field process. The device is installed on a traction device such as a tractor. Under the pushing of the traction device, the straw smashed in advance in the soil conservation zone can be concentrated and gathered into the ditch of the blank zone, realizing mechanized operation and improving agricultural efficiency. However, the gear wheel of the device is arranged vertically in an inclined manner. In actual use, the high-speed rotation of the gear wheel can easily raise dust, affecting the normal work of workers. On the other hand, part of the broken straw is left in the soil conservation zone during the straw side burying process. The straw left in the soil conservation zone can affect later sowing. During the corn sowing process, part of the seeds are blocked by the straw and cannot penetrate into the soil, resulting in the need for reseeding at the position. In addition, the straw needs to be smashed before the existing straw returning to field. However, a large amount of power energy is consumed during the smashing process, causing great energy consumption and high operation cost. SUMMARY

[0004] In order to solve the problems existing in the prior art, the application provides a whole-plant straw non-smashing deep returning to field burying device. The feeding channel is formed by arranging the guide plate and the horizontally arranged gear wheel. The whole-plant straw is extruded and pushed into the ditch of the blank zone, the conveying mode of the straw is changed, the problem of straw breaking and residue caused by the rotation of the gear wheel in the prior art is solved, and the phenomenon of dust raising caused by the rotation of the gear wheel is avoided to the greatest extent.

[0005] The specific technical scheme adopted by the application is as follows:

[0007] The both sides of the frame are provided with baffle plates, and the baffle plates form a falling slot between them, and the input end of the falling slot is connected with the output end of the feeding channel.

[0008] The poking mechanism is hinged to the poking wheel, and a clamping device is further connected between the poking mechanism and the poking wheel, and the poking mechanism and the poking wheel form an adjustable angle through the clamping device.

[0009] The clamping device comprises a fixed rod and a plurality of fixed buckles arranged on the fixed rod, the fixed rod penetrates the poking wheel and the poking mechanism, and the fixed buckles clamp the poking wheel and the poking mechanism to form fixation.

[0010] The poking mechanism comprises a plurality of vertical poking pieces uniformly distributed on the poking wheel, and a poking block is arranged at the front end of the poking piece, and the poking block is located between the poking piece and the guide plate.

[0012] A plurality of hook-shaped screening hooks are arranged at the front end of the dragging plate, the screening hooks are arranged in a zigzag shape, and the curved part of the screening hook is attached to the ground.

[0013] The frame is hinged to a rolling wheel through a connecting rod at the end, and the shaft of the rolling wheel is perpendicular to the ditch of the blank belt.

[0014] The ratio of the walking speed of the traction device to the rotating speed of the poking wheel is 1:1-1.2.

[0015] The beneficial effects of the present application are:

[0016] 1. Unlike the feeding mode of the prior art that the straw is swept into the ditch of the blank belt, the present application forms a feeding channel through the guide plate and the horizontally arranged poking wheel, and in the process of continuously advancing through the traction device, the straw enters the input end of the feeding channel, and under the rotation of the poking wheel, the poking mechanism pushes the straw along the guide plate to the output end of the feeding channel, and finally falls into the ditch of the blank belt. This process changes the carrying mode of the straw, solves the problem of straw crushing and residue caused by the vertical rotation of the poking wheel relative to the straw, and at the same time, the horizontal rotation of the poking wheel maximally avoids the phenomenon of dust raising when the poking wheel rotates.

[0017] 2. Since the carrying mode of the straw is changed, the straw does not need to be crushed before returning to the field, and the whole straw is carried by pushing and extruding, so that the energy consumption is greatly reduced and the operation cost is reduced during the straw returning process.

[0018] 3、The bottom of the feeding channel is provided with a drag plate, in the process of straw returning to field, the drag plate shovels up the broken straw on the soil conservation zone, meanwhile, the drag plate can also drag the debris generated in the rotating process of the poking wheel, the straw returning to field in the soil conservation zone is more thorough, with the entry of the subsequent straw, the debris or broken straw is squeezed to the output end of the feeding channel, avoiding the problem that the straw left in the soil conservation zone will affect the later sowing.

[0027] A whole-plant straw smashing-free deep returning to field burying device, comprising a rack 1 and a poking wheel 2 arranged on the rack 1, wherein the poking wheel 2 is provided with a poking mechanism, one side of the poking wheel 2 is provided with a guide plate 3, the guide plate 3 and the poking wheel 2 clench to form a feeding channel, the input end of the feeding channel faces the forward direction of the rack 1, the output end of the feeding channel is arranged above the ditch of the blank zone, and the rotating direction of the poking wheel 2 is from the input end of the feeding channel to the output end of the feeding channel.

[0028] Specific embodiments, such as Figures 1-6As shown, the current straw returning to field usually adopts ditching machine to open ditch channel on blank zone, and then adopts straw returning to field machine to crush and concentrate the straw of the soil conservation zone into the ditch channel of the blank zone for burying, the existing straw returning to field machine is arranged vertically, the high-speed rotation of the poking wheel 2 will raise dust, and the rotation direction is perpendicular to the straw, due to the one-year placement of the straw, the straw is weathered and easy to break and drop slag, which increases the difficulty of the subsequent straw cleaning work of the staff, the arrangement mode of the poking wheel 2 is changed, the feeding channel is formed by arranging the guide plate 3 and the horizontally arranged poking wheel 2, in the process of continuously advancing by means of the traction device, the straw enters the input end of the feeding channel, under the rotation of the poking wheel 2, the poking mechanism pushes and extrudes the straw to reach the output end of the feeding channel along the guide plate 3, and finally falls into the ditch channel of the blank zone, the conveying mode of the straw is changed, the problem of breaking and dropping slag of the straw caused by the vertical rotation of the poking wheel 2 relative to the straw is solved, the horizontal rotation of the poking wheel 2 avoids the phenomenon of raising dust when the poking wheel 2 rotates to the maximum extent, in addition, due to the change of the conveying mode of the straw in the embodiment, the straw does not need to be crushed before returning to field, the whole straw is conveyed by pushing and extruding, therefore, the energy consumption is greatly reduced and the operation cost is reduced during the straw returning to field process.

[0029] As shown in the Figure 1 The machine frame 1 is provided with a baffle 4 on both sides, a falling slot is formed between the two side baffles 4, the input end of the falling slot is connected with the output end of the feeding channel, and the width of the falling slot is the same as the width of the ditch channel of the blank zone, when the straw is inclined to enter the falling slot formed by the two side baffles 4 along the feeding channel, the straw will be stopped to one side baffle 4, under the obstruction of the baffle 4, the poking rod returns to the position parallel to the ditch channel and falls into the ditch channel in the direction of the ditch channel, so as to avoid the phenomenon that the straw is inclined and stuck above the ditch channel.

[0030] As shown in the Figure 5 The poking mechanism is hinged to the poking wheel 2, the poking mechanism and the poking wheel 2 are further connected with a clamping device, the poking mechanism and the poking wheel 2 form an adjustable angle by means of the clamping device, due to the different distances between the blank zone and the soil conservation zone in different fields, the required angle of the poking rod is also different, the poking wheel 2 and the poking mechanism of the present application are hingedly connected, the angle of the poking mechanism relative to the poking wheel 2 can be freely adjusted, when the required angle is adjusted, the clamping device is used for fixing, so that the poking mechanism maintains the required angle, the distance between the blank zone and the soil conservation zone can be adjusted, and the application range of the equipment is improved.

[0031] As shown in the Figure 5As shown, the clamping device includes a fixed rod 5 and a plurality of fixed buckles 6 arranged on the fixed rod 5, the fixed rod 5 penetrates the dial 2 and the dial mechanism, and the fixed buckles 6 clamp the dial 2 and the dial mechanism to form a fixed structure. The clamping structure in this embodiment is in the form of a fixed rod 5 and a fixed buckle 6, and the fixed rod 5 penetrates the dial 2 and the dial mechanism, and the fixed buckles 6 are arranged on both sides of the dial 2 and the dial mechanism respectively, so as to fix the dial mechanism to the desired angle.

[0032] As shown in Figure 2 and Figure 5 As shown, the dial mechanism includes a plurality of vertical dialing pieces 7 uniformly distributed on the dial 2, and a dial block 8 is arranged at the front end of the dialing piece 7, and the dial block 8 is located between the dialing piece 7 and the guide plate 3. The dial mechanism adopts a sheet structure, and since the straw forms multiple layers during laying, the dialing piece 7 with a certain width is adopted to increase the dialing area and ensure that all straws can be dialed. The dial block 8 is arranged at the front end of the dialing piece 7, so that the dial 2 provides a pushing force to the straw along the direction of the feeding channel when dialing the straw, so that the straw is more easily fed into the feeding channel. In addition, due to the more simplified structure of the dial 2 and the dial mechanism, the maintenance cost of the equipment in the later period is reduced.

[0033] As shown in Figures 1-2 and Figure 4 As shown, the clamping position of the dial 2 and the guide plate 3 is provided with a drag plate 9 perpendicular to the guide plate 3, and the drag plate 9 is connected with the bottom side of the guide plate 3, and the cross section formed by the drag plate 9 and the guide plate 3 is L-shaped. When the dial 2 dials the straw, a small part of the straw may break, causing the part of the straw to remain in place and unable to be extruded or pushed into the ditch by the dial 2. In this embodiment, the drag plate 9 is additionally arranged at the bottom of the feeding channel, and in the process of straw returning to the field, the drag plate 9 digs up the broken straw on the soil conservation belt, and at the same time, the drag plate 9 can also drag the debris generated during the rotation of the dial 2. The straw returning to the field on the soil conservation belt is more thorough, and with the entry of the subsequent straw, the part of the debris or broken straw is extruded to the output end of the feeding channel, avoiding the problem that the straw left in the soil conservation belt will affect the later seeding.

[0034] As shown in Figures 1-4 and Figure 6As shown, the front end of the drag plate 9 is provided with a plurality of hook-shaped screening hooks 10, which are arranged in a zigzag shape. The curved part of the screening hook 10 is in contact with the ground. Since the drag plate 9 is low, the soil on the ground will be scooped up during the forward movement. Therefore, a plurality of screening hooks 10 made of steel are arranged. The screening hooks 10 have a certain distance between the drag plate 9 and the ground, and the sand soil passes through the gap between the screening hooks 10, thereby avoiding the drag plate 9 from scooping up the soil on the ground during the forward movement. In addition, due to the uneven surface of the field and the existence of protruding stones, the drag plate 9 may be damaged by being pushed against the stones during the movement. The curved part of the screening hook 10 is arc-shaped, which helps the drag plate 9 to slide over the stones.

[0035] As shown in Figures 1-3 The frame 1 is hinged with a roller 12 at the end by means of a connecting rod 11. The axis of the roller 12 is perpendicular to the ditch of the blank belt. By arranging the roller 12 at the end of the frame 1, which matches the width of the ditch of the blank belt, the roller 12 can compact the straw once when the straw is filled into the ditch, thereby reducing the occurrence of straw lifting during the subsequent burying process and improving the burying effect.

[0036] Further, the ratio of the walking speed of the traction device to the rotating speed of the poking wheel 2 is 1:1-1.2. In order to further avoid the high-speed rotation of the poking wheel 2 from raising dust or breaking the straw, the present application controls the rotating speed of the poking wheel 2 by means of a transfer case, so that the rotating speed of the poking wheel 2 is always adapted to the forward speed of the traction device.
