Description
1. Technical Field
[0001] The invention relates to a device for throwing over soil after sowing in wide sowing belts and a planter equipped with the device, belonging to the technical field of planters.
2. Description of Related Art
[0002] Rice and wheat are the most important food crops, and the importance of ensuring their efficient and stable production is undoubted. In the main production areas of rice and wheat in China, the rice-wheat rotation double cropping system is the main farming system. Rice straw from the previous crop is large in amount and has high moisture content and high toughness and the soil in the rice stubble field is wet and sticky; in addition, mechanical sowing for next crop of wheat requires small row spacing and high distribution density of openers, which easily causes clogging. Considering the above restraining factors, how to realize the smooth and high-quality machine sowing of wheat in the field covered with the full amount of straw from the previous crop of rice has always been the difficulty and focus to be overcome.
[0003] For conventional mechanized sowing of wheat in the rice-wheat rotation area, it must be supported by straw crushing and returning machines, rotary tillers, and wheat planters. Various machines have to run in the field many times to complete the straw crushing, repeated soil rotary tillage, fertilization and sowing operations, which causes high production cost and high labor and time costs. For the sake of grabbing farming time, saving operating costs, or fully returning the straw to the field for fertilizer utilization, the production area urgently needs a machine that can achieve one-time smooth and high-quality mechanical sowing of wheat in the field covered with the full amount of straw in the previous crop of rice.
[0004] At present, there are two main types of wheat planters according to the type of sowing:
[0005] The first is a wheat drill planter which must be equipped with sowing openers. The wheat drill planter runs in the field to form seed furrows through the openers entering the soil.
The use of the wheat drill planter causes the following problem: due to the small row spacing of wheat sowing (generally only 10cm-15cm), the distribution density of openers is high, which easily causes clogging between the openers and hinders continuous and smooth operation.
[0006] The second is a wheat rotary planter, which operates in a way of sowing the seeds directly on the soil surface, and randomly mixing the seeds with the soil through rotary tillage blades. The use of the wheat rotary planter causes the following problem: although the hidden problem of clogging of the openers is eliminated, the operation of rotary tillage to hit the seeds causes a high rate of injury to the seed, increases the amount of seeds sown; in addition, the wheat rotary planter does not sow the seeds in soil, cannot control the sowing depth and has a high seed exposure rate (seeds cannot be covered with soil).
[0007] Therefore, how to realize the operation that in large-width sowing belts formed by straw laid in strips, the soil is rotary tilled and then thrown over backward, and the seeds are evenly sown on the ideal seed bed prepared by rotary tillage and then covered with the soil is a technical problem in the field that need to be solved urgently.
[0008] The objective of the invention is to realize the operation that in large-width sowing belts formed by straws laid in strips, the soil is rotary tilled and then thrown over backward, and the seeds are evenly sown on the ideal seed bed prepared by rotary tillage and then covered with the soil, so as to solve the technical problems of increasing the amount of seeds sown due to rotary tillage, not sowing seeds in the soil, being uncontrollable sowing depth, and causing a high seed exposure rate.
[0009] The invention adopts the following technical solutions
[0010] Provided is a device capable of throwing and covering soil after sowing in wide sowing belts, including a wide sowing-belt rotary tillage mechanism 601; two-sided baffles 604 fixed on both sides behind the wide sowing belt rotary tillage mechanism 601, a floating adjustable upper cover plate 603 being installed above the two-sided baffles 604, a rear retaining plate 605 being fixed behind the two-sided baffles 604; a soil backward-throwing guide plate 607 fixed within the two-sided baffles 604, the soil backward-throwing guide plate 607 being inclined backward and upward and spaced from the rear retaining plate 605 by a gap; and at least one seeding limit tube 606 fixed all the way at the bottom of the soil backward-throwing guide plate 607, all the seeding limit tubes 606 being located within the range of wide seeding belts, a seeding tube 602 being inserted into each seeding limit tube 606; wherein, the upper cover plate 603, the rear retaining plate 605, and the two-sided baffles 604 define a soil limiting space, the soil backward-throwing guide plate 607 separates the soil limiting space, and makes the soil thrown by the wide sowing-belt rotary tillage mechanism 601 during rotary tillage to move in an inverted L-shaped track to pass through the gap.

[0014] Provided is a planter capable of throwing and covering soil after sowing in wide sowing belts formed by straw laid in strips, including the device 6 capable of throwing and covering soil after sowing in wide sowing belts according to any of Claims 1 to 3, and further comprising a straw crushing and strip-pattern laying device 7 and a wide sowing-belt pressing wheel assembly 5, wherein, the device 6 capable of throwing and covering soil after sowing in wide sowing belts and the straw crushing and strip-pattern laying device 7 are hung by a rear three-point suspension 3, the wide sowing-belt pressing wheel assembly 5 is connected with the device 6 capable of throwing and covering soil after sowing in wide sowing belts through bolt fastening, a fertilizer box 2 is fixed on the top of the straw crushing and strip-pattern laying device 7, a seed box 4 is fixed on the top of the device 6 capable of throwing and covering soil after sowing in wide sowing belts, and the whole planter is power hung to a tractor through a frond three-point suspension 1.
[0015] Preferably, the straw crushing and strip-pattern laying device 7 includes a straw crushing mechanism 701, a strip-pattern laying device 702 is disposed behind the straw crushing mechanism 701, and the strip-pattern laying device 702 includes a pair of intersecting flat plates, the flat plates are arranged obliquely and can divert and shift the crushed straw to both sides and lay the crushed straw longitudinally in strips to form straw belts so that straw free wide sowing belts are formed between the straw belts; the device 6 capable of throwing and covering soil after sowing in wide sowing belts completes wide sowing-belt rotary tillage and sows wheat seeds evenly on the soil after the rotary tillage, the seeds are then covered with soil thrown up after the rotary tillage, and finally the wide sowing-belt pressing wheel assembly 5 completes the pressing operation to the wide sowing belts after sowing and soil covering.
[0016] Provided is a working method of a planter capable of throwing and covering soil after sowing in wide sowing belts formed by straw laid in strips, wherein the planter capable of throwing and covering soil after sowing in wide sowing belts formed by straw laid in strips as described above is adopted; when the planter moves forward to operate, the straw crushing mechanism 701 reversely rotates to crush all the straw in the working width, and the strip pattern laying device 702 behind cooperates with the straw crushing mechanism 701, and moves forward among the crushed straw to perform sliding cup so that the flowing crushed straw are diverted and shifted to both sides and laid longitudinally in strips to form straw belts, and straw-free large-width sowing belts, up to 26 cm wide, are formed between the straw belts and under the strip-pattern laying device 702, and fertilizer is transported to the wide sowing belts through fertilizer tubes 703; moreover, soil thrown by the wide sowing-belt rotary tillage mechanism 601 during rotary tillage is limited by the soil backward-throwing guide plate 607 and thus flies over the soil backward-throwing guide plate 607; below the soil backward throwing guide plate 607 is an area without soil disturbance after rotary tillage area, and seeds enter the seeding limit tubes 606 through the seeding tubes 602, and are directly sown in 2N rows evenly in the wide sowing belts; the soil thrown over the backward-throwing guide plate 607 during rotary tillage hits the upper cover plate 603 and the rear retaining plate 605, forms a soil curtain along the rear retaining plate 605, and then falls on and covers the seeds in the wide sowing belts.
[0017] Preferably, the minimum sliding cut angle of the strip-pattern laying device 702 must be 420, and the maximum diversion side shift angle of the strip-pattern laying device 702 must be 85°, so that the crushed straw can be smoothly diverted and shifted to sides and laid in strips longitudinally without clogging, thus ensuring the formation of 26cm wide straw-free wide sowing belts.
[0018] The invention has the following beneficial effects:
[0019] 1) A device capable of throwing and covering soil after sowing in wide sowing belts is created. During the rotary tillage, the device uses centrifugal force to transport the soil across a certain height and length in a closed space, provides an ideal seed bed prepared by rotary tillage for sowing, and then covers the seeds with soil. In the wide sowing belts, the seeds are evenly sown on the soil after the rotary tillage and the soil after sowing is then thrown backward to cover the seeds, ensuring the evenness of sowing in the wide sowing belts, the consistency of sowing depth and the reliability of soil covering. Specifically:
[0020] On one hand, since the sowing openers necessary for the traditional wheat drill planter are not needed any more, the structure is simplified, the length of the whole device is shortened, the center of gravity of the whole device is shifted forward, the lifting stability of the three-point suspension of the device lifted by the tractor is improved and the machine, and the problem of small wheat row spacing, high distribution density of openers, and high risk of clogging between openers.
[0021] On the other hand, the traditional wheat rotary planter directly sows seeds on the soil surface and mixes the seeds with soil through rotary tillage, causing the problems of high seed damage rate, large amount of seeds sown, uncontrollable sowing depth, and high seed exposure rate (seeds cannot be covered with soil). The invention overcomes these problems.
[0022] 2) A straw crushing and strip-pattern laying device is created. When straw is crushed but does not fall to the ground to form stable straw belts, the strip-pattern laying device moves forward among the flowing crushed straw to perform sliding cut, so that the crushed straw are diverted and shifted to both sides and laid in strips on the ground to form straw belts; straw free large-width sowing belts are formed between the straw belts (under the strip-pattern laying device), which is conducive to the subsequent smooth and high-quality sowing.
[0023] Further, it is clear that the strip-pattern laying device has the minimum sliding cut angle of 420 and the maximum diversion side shift angle of 85°, which can form straw-free wide sowing belts smoothly and without clogging, and the maximum width can reach 26cm.
[0024] 3) In a field covered with full straw of the previous crop of rice, the planter realizes all-in-one mechanical wheat sowing operation of strip-pattern laying of straw, even fertilizer application and sowing in wide sowing belts, soil backward throwing and covering after sowing, and wide sowing belt pressing. Rice straw from the previous crop is large in amount and has high moisture content and high toughness and the soil in the rice stubble field is wet and sticky; in addition, mechanical sowing for next crop of wheat requires small row spacing and high distribution density of openers. Considering the above restraining factors, a set of existing wheat planter cannot finish the whole mechanical sowing process in a round of operation in the field. The invention solves this problem.

2. Straw crushing and strip-pattern laying device:
[0041] Referring to Figs. 3-7, when the planter moves forward to operate, the straw crushing mechanism 701 reversely rotates to crush all the straw in the working width, and the strip-pattern laying device 702 behind cooperates with the straw crushing mechanism 701, and moves forward among the crushed straw to perform sliding cup so that the flowing crushed straw are diverted and shifted to both sides and laid longitudinally in strips to form straw belts, and straw-free large-width sowing belts, up to 26cm wide, are formed between the straw belts and under the strip-pattern laying device 702, and fertilizer is transported to the wide sowing belts through fertilizer tubes 703, as shown in Figs. 3-7.
[0042] In some embodiments, the minimum sliding cut angle of the strip-pattern laying device 702 must be 42, and the maximum diversion side shift angle of the strip-pattern laying device 702 must be 85°, so that the crushed straw can be smoothly diverted and shifted to sides and laid in strips longitudinally without clogging, thus ensuring the formation of 26cm wide straw-free wide sowing belts, as shown in Fig. 3.
3. Device capable of throwing and covering soil after sowing in wide sowing belts
[0043] Referring to Figs. 8-10, in the device capable of throwing and covering soil after sowing in wide sowing belts, the rotary tillage width of the wide sowing-belt rotary tillage mechanism 601 is 26cm, the same as the straw-free wide sowing belts formed by the straw crushing and strip-pattern laying device, the two-sided baffles 604 are welded and fixed on both sides of the wide sowing-belt rotary tillage mechanism 601, a floating adjustable upper cover plate 603 is installed above the two-sided baffles 604, and a rear retaining plate 605 is welded and fixed behind the two-sided baffles 604, so that soil thrown by the wide sowing-belt rotary tillage mechanism 601 during rotary tillage moves in a closed space; the soil backward throwing guide plate 607 is welded and fixed within the two-sided baffles 604; three seeding limit tubes 606 are disposed all the way on both sides of the two-sided baffles 604 and another three seeding limit tubes 606 are disposed all the way below the soil backward-throwing guide plate 607; the six seeding limit tubes 606 are evenly distributed in the wide sowing belts; and six seeding tubes 602 are respectively inserted into the seeding limit tubes 606 in one-to-one correspondence.
[0044] Referring to Fig. 8, when the device moves forward to operate, the soil thrown by the wide sowing-belt rotary tillage mechanism 601 during rotary tillage is limited by the soil backward-throwing guide plate 607 and thus flies over the soil backward-throwing guide plate 607; below the soil backward-throwing guide plate 607 is an area without soil disturbance after rotary tillage area, and wheat seeds enter the seeding limit tubes 606 through the seeding tubes 602, and are directly sown in six rows evenly in the wide sowing belts; the soil thrown over the backward-throwing guide plate 607 during rotary tillage hits the upper cover plate 603 and the rear retaining plate 605, forms a soil curtain along the rear retaining plate 605, and then falls on and covers the wheat seeds in the wide sowing belts, thus finishing the operation of soil throwing and cover after even sowing of wheat in wide sowing belts formed by straw laid in strips.
[0045] The innovations of the invention are described in detail below:
[0046] First of all, a device capable of throwing and covering soil after sowing in wide sowing belts is created. During the rotary tillage, the device uses centrifugal force to transport the soil across a certain height and length in a closed space, provides an ideal seed bed prepared by rotary tillage for sowing, and then covers the seeds with soil. In the wide sowing belts, the seeds are evenly sown on the soil after the rotary tillage and the soil after sowing is then thrown backward to cover the seeds, ensuring the evenness of sowing in the wide sowing belts, the consistency of sowing depth and the reliability of soil covering. Specifically, on one hand, since the sowing openers necessary for the traditional wheat drill planter are not needed any more, the structure is simplified, the length of the whole device is shortened, the center of gravity of the whole device is shifted forward, the lifting stability of the three-point suspension of the device lifted by the tractor is improved and the machine, and the problem of small wheat row spacing, high distribution density of openers, and high risk of clogging between openers. On the other hand, the traditional wheat rotary planter directly sows seeds on the soil surface and mixes the seeds with soil through rotary tillage, causing the problems of high seed damage rate, large amount of seeds sown, uncontrollable sowing depth, and high seed exposure rate (seeds cannot be covered with soil). The invention overcomes these problems.
[0047] Second, a straw crushing and strip-pattern laying device is created. When straw is crushed but does not fall to the ground to form stable straw belts, the strip-pattern laying device moves forward among the flowing crushed straw to perform sliding cut, so that the crushed straw are diverted and shifted to both sides and laid in strips on the ground to form straw belts; straw-free large-width sowing belts are formed between the straw belts (under the strip-pattern laying device), which is conducive to the subsequent smooth and high-quality sowing.
[0048] Further, through repeated research, it is clear that the strip-pattern laying device has the minimum sliding cut angle of 420 and the maximum diversion side shift angle of 850, which can form straw-free wide sowing belts smoothly and without clogging, and the maximum width can reach 26cm.
[0049] Third, in a field covered with full straw of the previous crop of rice, the planter realizes all-in-one mechanical wheat sowing operation of strip-pattern laying of straw, even fertilizer application and sowing in wide sowing belts, soil backward throwing and covering after sowing, and wide sowing belt pressing. Rice straw from the previous crop is large in amount and has high moisture content and high toughness and the soil in the rice stubble field is wet and sticky; in addition, mechanical sowing for next crop of wheat requires small row spacing and high distribution density of openers. Considering the above restraining factors, a set of existing wheat planter cannot finish the whole mechanical sowing process in a round of operation in the field. The invention solves this problem.
[0050] Therefore, in a field covered with full straw of the previous crop of rice, the planter of the present realizes all-in-one mechanical wheat sowing operation of strip-pattern laying of straw, even fertilizer application and sowing in wide sowing belts, soil backward throwing and covering after sowing, and wide sowing belt pressing. It focuses on realizing the operation that in large-width sowing belts formed by straw laid in strips, the soil is rotary tilled and then thrown over backward, and the seeds are evenly sown on the ideal seed bed prepared by rotary tillage and then covered with the soil. The invention solves the above problems.
