Description

A cottonseed planter reserved between rows for double cropping of wheat and cotton

technical field

The present invention relates to the technical field of agricultural sowing, in particular to an agricultural seeder used in reserved rows for double-cropping of wheat and cotton, more specifically a double-row reserved row for cotton seeds and wheat-cotton double-cropping suitable for wheat field intercropping or continuous cropping Cotton seed planter.

Background technique

Under the conditions of our country with more people and less land, increasing the crop multiple cropping index and expanding the sown area is an important way to relieve the pressure on cultivated land, ensure food security and simultaneously increase the yield of other crops. Therefore, in agricultural areas with abundant resources such as sunlight and warm heat, the development of double or even multiple cropping technologies in one season can realize the production of a variety of agricultural products within a year, thereby maximizing the use of natural resources. Taking the Huang-Huai-Hai Plain as an example, it is an important dryland double-cropping area in my country. Wheat, cotton, wheat-corn, and wheat-soybean are the main double-cropping planting patterns in this area; The main stubble.

As the saying goes, "ten seedlings, seven minutes sowing", the quality of sowing will greatly affect the management of later growth, especially the double-cropping planting and production under the intercropping/continuous cropping mode. Taking the double cropping mode of wheat and cotton as an example, since the height of the wheat plant at the mature stage is generally within 60-100 cm, the existence of the previous wheat row and the formation of a certain height of the row wheat plant group (called wheat forest), resulting in The sowing of subsequent crops is only limited to the reserved rows between the wheat groves or the empty rows between wheat stubbles after harvesting, which is unfavorable for the sowing of subsequent crops and extremely inconvenient to operate. In addition, according to research, in the horizontal direction of the reserved row (that is, the future cotton sowing row), the closer the distance to the wheat seedlings, the drier the soil, the more unfavorable for cotton seedling emergence; but in the vertical direction of the reserved row, each The moisture content of the soil layer varies greatly, with obvious temporal and spatial differences. For example, when the wheat is watered during flowering, the wheat consumes a lot of water, and the topsoil at 0-5cm turns white and becomes dry in less than 3 days, while the soil moisture at the 5-15cm layer is significantly better than the surface layer. How to use the moisture content of different soil layers to realize the one-sow full seedling and the neat growth of cottonseed in double cropping of wheat and cotton has become the primary research purpose of the development of seeder and sowing technology research and development.

At present, the intercropping/continuous cropping sowing techniques and methods in the wheat stubble field mainly adopt the traditional sowing methods: one is to artificially open ditches or spot seeds, and perform on-demand sowing or ditch pendulum sowing according to the sowing density to complete the sowing; the other is to use single-row small The machine tool is used for ditching and planting, and this kind of sowing method requires manual advancement or assistance. The problems of the above-mentioned technology are: (1) the labor is very expensive, which leads to the increase of the sowing cost and the high labor intensity, which is not conducive to the development of light and simplified management and modern agriculture; , texture and other factors are not stable; (3) the models of small machines are inconsistent, and the regional adaptability is poor. Because the belt planting configuration of wheat and cotton is not uniform, and the standards of each planting row in the double-cropping agricultural area are also inconsistent, resulting in the existing technology The sowing agricultural implement disclosed in is difficult to apply.

For example, patent CN103975673A discloses a wheat field interplanting planter that is driven by a DC motor and can adjust the planting spacing. It mainly includes the support plate, wheels, material hopper, feeding pipe, handrail, transmission, etc., as well as the rotating shaft and gear set on the hub motor, the rotating shaft connects the material hopper and the feeding pipe, and the battery and controller on the supporting plate, etc. , the seeder drives the wheel hub motor through the battery, controller and transmission to realize the automatic forward movement of the seeder, saving time and effort. The storage chamber is opened on the rotating shaft, and the gears of different sizes on the transmission chain and the gear set can be set. plant distance.

For another example, the patent CN90204417Y discloses a small interplanting planter, which includes a frame, a drawbar, an adjustment screw, a hopper, a rotating shaft, a ditch opener, a compounder and a traveling wheel, as well as a sleeve baffle plate and a grooved wheel below. The machine is mainly used for semi-automatic and semi-manual operations for interplanting or small areas. Correspondingly, some single-cook field seeding machines are also being developed and designed to improve the field sowing efficiency of large-scale one-cook or stubble-free fields. There are seeders with different seeders driven by traction, such as Xinjiang The double-row duckbill seed metering device for the land unit is suitable for the air-suction single-row seeder for the dry land in the north. In addition, there are hand-push trenching shovels suitable for the south.

For another example, the patent CN104350845A discloses a planter, which includes a frame and a seeder mounted on the frame. The front side of the frame is equipped with rollers, and the rear side is equipped with soil rollers. The seeder There is a discharge port at the bottom of the machine. The ditching shovel is installed in front of the discharge port, and the scraper is in the rear. There is also a push rod on the frame for cultivation.

However, how to carry out sowing in wheat groves before wheat harvest requires a reasonable design of sowing tools based on the traveling wheel base that is compatible with the wheat and cotton configuration mode and bandwidth, the soil state of the reserved row, and the mode characteristics of the two crops. , so that the sowing farm tools can effectively treat the soil, sow the ditch, drop the seeds and cover the soil, and adapt to the soil moisture in the double-cropping planting mode, so as to realize the mechanized sowing of summer crops and the problem of one-time sowing of all seedlings. Apparently above-mentioned planting implement all can't realize this function.

The inter-row cotton seed planter reserved for double cropping of wheat and cotton, by adjusting the height of each part, can make full use of the characteristics of soil moisture and temperature changes in the multi-cropping planting mode for sowing treatment, and control the cotton sowing depth and quantification of covering soil. It is helpful to realize the seedling uniformity and is beneficial to the emergence management of double-cropped cotton.

Of course, because the cotton seed planter in the row reserved for double cropping of wheat and cotton in this embodiment has a high degree of automation, it does not need to rely too much on manual operations, and its operation is simple.

Among them, the primary crushing parts are used to carry out preliminary crushing of the soil, so as to facilitate the scraping action of the scraping and leveling parts, and prevent the hard soil from causing the problem of large travel resistance of the cotton seed planter between the rows reserved for double cropping of wheat and cotton. Moreover, during the operation of the inter-row cottonseed planter reserved for double-cropping wheat and cotton in this embodiment, only one traction power unit needs to be connected, and then it can complete the sowing independently without manual assistance, so that this kind of double-cropping wheat and cotton is reserved Inter-row cottonseed planter with high automation.

Further, in Fig. 1 , the cottonseed planter between the rows reserved for double cropping of wheat and cotton is also equipped with a stalk support component 1 on the frontmost side of the frame 7, which is used to push the crops tilted into the sowing area of the reserved cotton row. Open righting or clean up. It is preferable but not necessary that the stalk support part 1 is in the shape of a horse's head, so that its front side can move to the bottom of the fallen crops; as the cotton seed planter moves forward, the crops will stick to the stalk support part 1 moves to the rear side of the stalk support part 1, so that the crop is righted by its rear side and leaves the sowing area. Of course, the stalk supporting part 1 is not a necessary structure of the inter-row cottonseed planter reserved for double-cropping wheat and cotton. Specifically, whether to install the stalk-supporting part 1 can be selected depending on the use environment of the cotton seed planter between the rows reserved for double-cropping wheat and cotton.

It should be noted that, in this embodiment, "front" and "back" are relative to the direction of movement of the cotton seed planter between the rows reserved for double cropping of wheat and cotton. For example, in Figure 1, since the cotton seed planter in the row reserved for double cropping of wheat and cotton must move towards the left side of Figure 1, the left side in Figure 1 refers to "front", while in Figure 1 The right side refers to the "back".

Please refer to FIG. 2 , in order to reduce the weight of the stalk supporting member 1 , it is preferable that the stalk supporting member 1 is hollow, so that its cross section is "V" shaped.

Please refer to Fig. 2 further. When the inter-row cottonseed planter reserved for double cropping of wheat and cotton includes the stalk support component 1, the primary crushed soil component 2 can be installed on the bottom plate of the stalk support component 1, so that the primary crushed soil component 2 passes through the The stalk supporting component 1 is installed on the frame 7 . Certainly, under the condition that the culm raising member 1 is not provided, the primary soil breaking member 2 may also be directly installed on the frame 7 .

In FIG. 2 , the primary crushing component 2 includes a mounting frame 21 and a runner 22 . The mounting frame 21 is in an inverted U shape and is fixed on the bottom plate of the stalk holding part 1. The runner 22 is mounted on the mounting frame 21, and the surface of the rotary wheel 22 is provided with Gear teeth 23. Wherein, the gear tooth 23 can adopt any specification, preferably adopt double-sided cutting tooth here, in order to realize better earth breaking effect. In addition, in order to ensure the effectiveness of the primary soil breaking component 2, it is preferable but not necessary to set a brush 24 for cleaning the gear teeth 23 on the mounting frame 21, so that the primary soil breaking component 2 has a self-cleaning function. Of course, in addition to the brush 24, other forms of cleaners can also be used to clean the primary earth breaking part 2.

Further, the soil scraping and leveling member 3 is a V-shaped scraper that is vertically arranged with the top angle facing forward. It can be seen from FIG. 1 that the frame 7 includes a first support rod protruding downwards, and the V-shaped scraper as the scraping leveling component 3 is fixed on the first support rod. Moreover, the V-shaped scraper can also play a certain auxiliary supporting role for the horse-head-shaped stalk-holding member 1 . Moreover, the top angle of the V-shaped scraper has a certain soil-breaking effect, and the force-bearing area is larger, so that compared with the scraper in the prior art, it has stronger soil-scraping ability and greater structural strength. Of course, the structure of the soil scraping and leveling component 3 is not limited by the accompanying drawings, and any structure with a soil scraping function disclosed in the prior art is included in the scope covered by the soil scraping and leveling component 3 of the present application.

As can be seen from Fig. 3, opener 9 is a plow share. And, a feeding pipe 10 is arranged on the rear side of the plowshare, and the seed meter 8 spreads seeds into the groove through the feeding pipe 10 . Wherein, preferably, a funnel for accepting seeds is provided at the top of the drop tube 10 . Of course, the structure of the gag 9 is not limited by the accompanying drawings.

Further, the soil returning component 4 is a vertically arranged soil returning scraper. Referring further to FIG. 3 , the returning soil scraper includes parallel plates arranged in parallel on both sides of the ploughshare and the discharge pipe 10 , and a closing plate that gradually closes up from front to back. The parallel plates are used to collect the soil that has been pushed apart, and the soil is further backfilled into the trench through the closing plate. Among them, in order to better gather the soil, the parallel plate can also be properly adjusted to expand outward, wherein the angle of outward expansion can be between 10°-20°. The soil return scraper has a simple structure, and at the same time, because it has a certain guiding function for the flow direction of the soil, it can obtain a better soil backfill effect.

Please refer to Fig. 3 further. At this time, the plow share, the feeding pipe 10 and the return soil scraper are relatively fixed and have a compact structure, thereby reducing the size of the frame as a whole. Further, the ploughshare, the feeding pipe 10 and the returning soil scraper are installed on the second support rod protruding downwards from the frame 7 . In this case, after the plowshare has opened the furrow, the seeds in the feeding pipe fall into the furrow immediately, and the soil return scraper starts to backfill the soil into the furrow while the seed falls. Therefore, ditching, sowing and returning soil can be completed in one step almost in the present embodiment.

Of course, the plowshare, the feeding pipe 10 and the returning soil scraper can also be arranged successively along the front and rear directions of the frame, and are independent of each other, so that ditching, sowing and returning soil can be divided into three successive steps to complete.

Preferably, but not necessarily, a soil compacting element 5 is also provided on the frame 7 . Wherein, the soil compaction part 5 is located at the rear side of the soil return part 4 and the front side of the soil covering arrangement part 6, and is used for compacting the soil backfilled in the ditch. On this basis, the soil covering finishing part 6 and the soil compacting part clean up the compacted soil surface and control the thickness of the covering soil after sowing.

In this embodiment, it is preferred that the soil compaction component 5 is a rotary pressing wheel, which includes two rollers, and the two rollers are connected by a shaft; the soil covering finishing component is a V-shaped scraper arranged vertically with the top angle facing forward. Please further refer to Fig. 1 , the connecting shaft of the rotating pressing wheel is fixed on the third support bar protruding downwards from the frame 7, and the covering soil arrangement component 6 is fixed on the fourth support bar protruding downwards from the frame 7. Of course, the structures of the soil compacting component 5 and the soil-covering finishing component are not limited by the accompanying drawings.

On the basis of the above, it is preferable to install the stalk support part 1, the primary crushed soil part 2, the soil scraping and leveling part 3, the ditch opener 9, the seed metering device 8, the soil returning part 4, the soil compaction part 5 and the covering soil finishing part 6 On the central axis of frame 7. And, the installation sequence along the central axis of the frame 7 is: the stalk support part 1 and the primary crushed soil part 2 - the soil scraping and leveling part 3 - the ditch opener 9, the drop pipe 10 and the returning soil part 4 - soil pressure Real part 5—soil-covering finishing part 6. In this case, the cotton seed planter between rows reserved for double cropping of wheat and cotton has simple structure and reasonable space.

In this embodiment, in order to disperse individual seeds and reduce seedling waste and thinning costs, it is preferable to use the seed metering device 8 shown in FIG. 4 .

Wherein, the seed metering device 8 includes a seeding wheel, a track housing 85 and a seed feeding hopper 84, the track housing 85 has a ring-shaped track cavity, and the track cavity has an inner ring opening; the seed metering wheel includes a spoke wheel 86 and a plurality of seed distribution boards, a plurality of the seed distribution boards are arranged at intervals in the track cavity of the track shell 85, and two adjacent seed distribution plates form a seed distribution cavity with the inner ring plate and the track shell 85 The circumferential direction of the spoke wheel 86 is provided with a plurality of spokes 87, and the spoke wheel 86 drives the seed distribution plate to move along the track cavity through the spokes 87; the inner ring opening of the track cavity is provided with a Inner ring plate; each seed distribution plate is provided with a seed spoon in front; the track shell 85 is provided with a seed inlet 83 and a seed injection port 82, and the seed inlet 83 is fan-shaped; the seed feeding bucket 84 Installed on the seed inlet 83, a fan-shaped cavity is formed in the seed inlet 83; the seed inlet 82 is connected with a drop tube 10, and the drop tube 10 is located at the rear side of the plowshare.

And, as can be seen from FIG. 4 , the number of the seed wheel and the track shell 85 corresponding to the single seed feeding hopper 84 is two, and the two seed wheels and the track shell 85 are relatively opposite to the seed feeder. The buckets 84 are distributed symmetrically, thereby obtaining a double row cottonseed metering device. The double-row cotton seed metering device can obtain two rows of seeds, and at the same time expands the seeding distance to increase the sowing density and improve the land utilization rate. Wherein, the second support rod passes between the two seeding wheels and the track housing 85 . Of course, it should be noted that the structure of the double row cotton seed metering device is not limited by this embodiment.

Further, it can be seen from FIG. 1 that the above-mentioned seed meter 8 is fixed on the frame 7 through the rail mounting plate 81 .

The wheat and cotton double-cropping cottonseed planter reserved between rows in this embodiment increases the number of rows and plants by using a double-row cotton seed metering device, which is beneficial to increase the sowing rate, increase the number of seedlings, and reduce the double-ripening cotton in intercropping or continuous cropping. Lack of seedlings breaks the ridges, and reduces the phenomenon of "saplings and seedlings" and the cost of thinning.

Of course, it should be noted that the seed metering device 8 can also choose a single-row structure, that is, the number of the seed metering wheel and the track shell 85 corresponding to the single seed feeding hopper 84 is one, thereby simplifying the construction of the seed metering device 8 The structure reduces the production cost of the cotton seed planter in the row reserved for double cropping of wheat and cotton. And, the seed meter 8 can also choose other forms disclosed in any prior art.

The wheat-cotton dual-cropping reserved inter-row cottonseed planter of this embodiment can adapt to the configuration of wheat grove/wheat stubble row spacing, and operate in the cotton reserved rows in the wheat field, so it is suitable for the intercropping/continuous cropping mode of wheat grove/wheat stubble.

On the basis of the above, this embodiment provides a set of optional parameters of the above-mentioned inter-row cottonseed planter reserved for double cropping of wheat and cotton: wherein, the height of the horse head-shaped stalk support part 1 is 70cm-90cm. The axial length of the runner 22 of the primary broken soil part 2 is about 30cm; 4-5 rows of gear teeth 23 are distributed along the circumferential surface of the runner 22, and the number of each row of gear teeth 23 is 4-5. The tooth depth is 2cm-3cm; and the landing height of the primary crushed soil part 2 can be adjusted. When both the soil scraping leveling part 3 and the covering soil finishing part 6 adopt V-shaped scrapers, the soil scraping and leveling part 3 adopts a large "V" shape, and the width of the bottom angle is 10cm-15cm; the covering soil finishing part 6 adopts a small "V" shape, and the bottom Corner width 8cm-10cm. When furrow opener 9 adopted the form of plowshare, its tip angle was 25 °-35 °, and the lower bottom was semi-closed.

And, with the height of the soil surface before the sowing operation as a benchmark, the bottom horizontal height of the soil scraping leveling part 3 is about 4cm-8cm lower than the reference height, so that the dry soil on the surface can be pushed aside to expose the inner layer of soil; On the basis of the inner layer of soil, dig out the deep trench of 5-7cm and sow down, that is, the diameter length of the cross-section of 10-15 sowing crop seeds; The bottom of the bottom edge of the plowshare is about 3-5cm high; and as the V-shaped scraper of the covering soil finishing part 6, its bottom is 2-3cm higher than the bottom of the bottom edge of the plowshare, that is, 4-6 sowing crop seed cross-sectional diameters length.

Wherein, the height difference between the bottom edge of the ploughshare and the bottom edge of the scraping soil leveling part 3 is conducive to reasonably clearing the arid soil surface with a certain thickness reserved for two crops of wheat and cotton; It is beneficial to obtain reasonable cotton seed sowing soil thickness. Of course, the specific height difference can be properly adjusted according to different environments.

And, according to the effective sowing spacing, the distance between the adjacent seed spoons of the seed meter 8 is preferably 8cm-10cm, so that the seeds move along the circumferential direction in the closed track cavity, and when moving to the seeding port 82 at the lower end, Finish planting, and each track shell 85 plants 1 grain at every turn, falls in the groove, forms two rows of seeds.

When the above-mentioned cotton seed planter reserved for double cropping of wheat and cotton is used in the wheat-cotton interleaving mode:

The assembled wheat-cotton double-cropping reserved inter-row cottonseed planter was tested in the field. It adopted a traction power of 60 horsepower to complete the machine operator's familiarization and running-in process of the wheat-cotton double-ripened reserved inter-row cottonseed sower. Then start the field sowing operation. The sowing test was carried out on May 15, 2015 at the experimental farm of the Chinese Academy of Agricultural Sciences. The experimental field is planted as ribbon-shaped wheat with a width of 70 cm. Three rows of wheat are planted within a total area of 30 cm, and an open space of 40 cm is reserved for planting cotton. The designed cotton planting density is 6,000 plants/mu, and the variety is Zhongmian 50. The germination rate of cotton seeds of this variety was 86% in 2014, so the number of sown grains is 9,500 grains/mu. The seeding quantity is 11.2 grains/m. When the wheat is in the early stage of grouting, water 15 square meters per mu on May 12 before sowing, and lightly use the "horse race water" to achieve two uses of water, which can be used for wheat grouting and as water for cotton sowing; The water consumption of the reserved row plow layer in the symbiotic period is relatively large, but the water content distribution of each soil layer is different, showing a spindle-shaped distribution. The measured water content of the 0-5cm soil layer is 18.5%, while the 5-15cm water content is 22%. About, 15-30cm water content 20.5%. The sowing time was completed on May 15, and the emergence time was May 23. The emergence effect was good. The average emergence number of 10 points was 8.8 grains/m, the emergence rate was 78.6%, and the ridging rate was 3.5%. Refers to the emergence of seedlings between the rows of the field where the length gap between two seedlings is greater than 50 cm. However, using the conventional cottonseed planter reserved between rows for double cropping of wheat and cotton combined with conventional sowing methods, the rate of seedling deficiency and ridging can reach more than 15%, and the rate of emergence is 66%, and the quality of emergence is relatively irregular.

When using the cottonseed planter reserved between rows for double cropping of wheat and cotton in the continuous cropping mode of wheat and cotton:

The assembled wheat and cotton double cropping reserved inter-row cottonseed planter for field test. The wheat harvest was completed on June 9th in the test site. The cotton continuous cropping test was carried out on June 10, 2015 at the experimental farm of the Chinese Academy of Agricultural Sciences conduct. The experimental field is planted as ribbon-shaped wheat with a width of 70 cm. Three rows of wheat are planted inside, occupying an area of 30 cm, and an open space of 40 cm is reserved for sowing cotton. The cotton planting density is designed to be 6000 plants/mu, and the variety is Zhongmiansuo 50, so the number of sown grains is 8465 grains/mu, and the grain spacing of a single row is designed to be 22.5 cm, and the average seeding amount of two rows is 8.9 grains/m. After sowing, the whole seedlings were watered 15 cubic meters per mu. Seedlings emerged on June 17, and the emergence effect was good. The average number of seedlings emerging at 10 points was 7.5 grains/m, the rate of seedling emergence was 84.2%, and the rate of ridging was 2.5%. However, using the conventional cottonseed planter reserved between rows for double cropping of wheat and cotton combined with the conventional sowing method, the rate of missing seedlings and ridging can reach more than 12.5%, the rate of emergence is 75.1%, and the quality of emergence is relatively irregular.

Through the above experiments, it was found that using the cottonseed planter reserved for double cropping of wheat and cotton in this embodiment for sowing, the crops have a low rate of lack of seedlings and broken ridges, a high rate of emergence and high quality of emergence, thereby having better sowing effects .

In summary, the inter-row cottonseed planter reserved for double cropping of wheat and cotton in this embodiment is suitable for mechanized sowing of cotton crops in intercropping of wheat stubble or continuous cropping of stubble, which can greatly improve the emergence rate and quality of seedlings, and at the same time ensure a Sow full seedlings, reduce labor for thinning seedlings, and also reduce the probability of lack of seedlings and broken ridges, which has broad application prospects.
