Description

Technical Field

[0001] The invention relates to the field of agricultural machinery, and in particular to an oat or barley harvester interplanted with corn and a production method of silage. Background Art

[0002] Northeast China, as my country's granary, is an important main production area of ​​corn in my country. In Heilongjiang Province, due to the cold climate, local corn is generally planted in May and harvested in October, and can only be planted once a year. This means that between November of each year and May of the following year, the land for planting corn is idle, and the land utilization rate is low. The model of planting corn first and then oats or barley on corn fields, so that oats or barley are interplanted with corn, is called the "Yumiao Interplanting Model". The "Yumiao Interplanting Model" makes full use of land and light and heat resources, which will not only not reduce corn production, but also promote the harvest of oats or barley, achieving "double harvests in one land", and improving land utilization. It is a new agricultural planting model that is very suitable for my country's Northeast region.

[0003] In the "Yellow-Wheat Intercropping Mode", during the period from corn sowing to oats or barley harvesting, oats or barley grow together with corn on the same land. Traditional harvesters will damage corn when harvesting oats or barley, and are not suitable for the "Yellow-Wheat Intercropping Mode". How to harvest oats or barley without damaging corn has become the primary problem encountered by the "Yellow-Wheat Intercropping Mode". To this end, the Chinese invention patent with application number 202321888073.X discloses a crawler-type oat silage combine harvester, which is provided with two symmetrically arranged harvesting devices in front of the machine body, a storage hopper is provided at the upper rear end of the machine body, and a crawler walking mechanism is provided under the machine body. Space for corn to pass is left between the two harvesting devices and between the two crawler walking mechanisms, thereby achieving the harvesting of oats or barley without damaging corn, solving the primary problem of the "Yellow-Wheat Intercropping Mode".

[0004] However, the "crawler-type oat silage combine harvester" disclosed in the current Chinese invention patent application number 202321888073.X has the following shortcomings: (1) There are only two harvesting devices, and only two rows of oats can be harvested in one trip, which will leave out the middle row of oats. If the middle row is to be harvested, another trip is required, which greatly reduces the harvesting efficiency of oats or barley; (2) The walking mechanism is designed to be crawler-type, which not only has a slow travel speed, but also must be disassembled and assembled for long-distance transfer operations, which is very inconvenient, resulting in low operating efficiency of the harvester; (3) A shredding device is used to shred the harvested oat silage to obtain oat or silage grains. This method of obtaining grains by shredding is too inefficient.

[0005] In summary, the shortcomings of the current first-generation oat or barley harvesters reduce the overall harvesting efficiency of oats or barley, which will not only affect the jointing period of corn and thus affect the corn yield, but also cause the quality of oats or barley to decline due to untimely harvesting. Summary of the invention

DETAILED DESCRIPTION

[0024] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0025] When oats or barley are harvested in mid-to-late June, the corn in the black soil of Northeast China has not yet entered the jointing stage. If the harvesting efficiency of oats or barley is too low, it will not only affect the jointing period of corn and thus affect the corn yield, but also cause the quality of oats or barley to decline. Therefore, the harvesting period of oats or barley is allowed to be very short, usually concentrated from June 10th to June 20th, which means that oats or barley only have a harvesting period of more than ten days. Therefore, how to improve the harvesting efficiency of oats or barley is a technical problem to be solved by the present invention. First, a harvesting device is added between the two original harvesting devices, spanning three oat ridges. When two rows of oats are harvested in one trip, the middle row of oats that was originally dropped is harvested at the same time, so that three rows of oats can be harvested in one trip. This not only improves the harvesting efficiency by one third at one time, but also saves the time for adding another trip due to re-harvesting the middle row of oats. Secondly, the original crawler wheels are cancelled and replaced with four-wheel drive. Preferably, the two front wheels are triangular crawler wheels, which not only retains the advantages of crawler stability, but also The operation efficiency is greatly improved; finally, the original silk kneading device is improved into a grain crushing device, which includes a flattening mechanism and a straw-cutting mechanism, the flattening mechanism flattens the harvested oat or barley straw to obtain flattened oat or barley straw, the straw-cutting mechanism chops the flattened oat or barley straw to obtain a mixture of chopped straw and oat or barley grains, the mixture of chopped straw and oat or barley grains is blown by an air conveying device, wherein the oat or barley grains fall into a storage hopper, thereby realizing the harvest of oats or barley interplanted with corn, and improving the processing efficiency of oat or barley grains.

The harvester disclosed in the present invention has made the following improvements to the efficiency-limiting shortcomings of the "crawler-type oat silage combine harvester" disclosed in the Chinese invention patent with application number 202321888073.X: First, an intermediate harvesting device 33 is arranged between the left harvesting device 31 and the right harvesting device 32, and a reel 301 is arranged at the front end of the left harvesting device 31, the intermediate harvesting device 33 and the right harvesting device 32, and a header 302 is arranged behind the reel 301, and wheat ear elevators 34 are arranged behind the left harvesting device 31, the intermediate harvesting device 33 and the right harvesting device 32, respectively. The headers 302 of the left harvesting device 31, the intermediate harvesting device 33 and the right harvesting device 32 are connected to the auger conveyor 11 through their respective wheat ear elevators 34.

[0028] It should be noted that the "corn and wheat intercropping model" adopts the "4090" model, that is, the land is divided into rows of 40 cm and 90 cm, two rows of corn are planted in the 40 cm area to form a ridge, and four rows of oats are planted in the middle 40 cm of the 90 cm area to form a ridge. A gap of 25 cm can be left between the oats and corn to facilitate later harvesting.

[0029] In the corn-wheat intercropping pattern, a row of oats or barley is pre-planted in the planting area corresponding to the width range of the left harvesting device 31, the middle harvesting device 33 and the reel 301 at the front end of the right harvesting device 32, and a row of corn is pre-planted in the planting area corresponding to the gap between the middle harvesting device 33 and the left harvesting device 31 and the gap between the middle harvesting device 33 and the right harvesting device 32, thereby forming an intercropping pattern in which a row of oats or barley is separated from a row of corn.

[0030] When the harvester is used to harvest oats or barley in the corn-wheat intercropping mode, the reels 301 of the left harvesting device 31, the middle harvesting device 33 and the right harvesting device 32 respectively deliver the oats or barley to the header 302, and the header 302 harvests the oats or barley. The harvested oats or barley are transported to the auger conveyor 11 through the wheat ear elevator 34; The oats or barley harvested by the left harvesting device 31, the middle harvesting device 33 and the right harvesting device 32 are gathered together in the auger conveyor 11; The grain crushing device 2 crushes the harvested oat or barley grains and chops the straw to obtain a mixture of chopped oat or barley straw and crushed oat or barley grains; The air conveying device 20 blows out the mixture of chopped oat or barley straw and crushed oat or barley grains and drops it into the storage hopper 12, thereby harvesting the oats or barley interplanted with corn.

[0031] Specifically, the width of the reels 301 at the front ends of the left harvesting device 31 , the middle harvesting device 33 and the right harvesting device 32 is in the range of 57 cm.

[0032] During the process of the harvester harvesting oats or barley in the corn-wheat intercropping mode, the reels 301 of the left harvesting device 31, the middle harvesting device 33 and the right harvesting device 32 are respectively facing a ridge of oats or barley.

When oats or barley are interplanted with corn, they grow together on the same land from sowing corn in May to harvesting oats or barley in mid-to-late June. When harvesting oats or barley, it is necessary to ensure that the harvest is completed without damaging the corn. When harvesting oats or barley in mid-to-late June, corn has not yet entered the jointing stage, and the height of the two is about the same, about 1 to 1.2 meters.

[0036] In addition to not damaging the corn in terms of row spacing, the chassis 10 of the harvester cannot be too low, otherwise the corn will be damaged, that is, the height of the chassis 10 is required to be higher than the corn when harvesting oats or barley. Since the maximum height of corn when harvesting oats or barley is 1.2 meters, the height of the chassis 10 is not less than 1.2 meters. As a specific embodiment, the height of the chassis 10 of the harvester is 1370 cm.

[0037] Second, in order to improve the operation efficiency, the original crawler wheels are eliminated, and four wheels are arranged under the chassis 10 , wherein two front wheels are located at both ends of the auger conveyor 11 , and two rear wheels are located directly below the storage hopper 12 .

[0038] In order to ensure stability, among the four wheels below the chassis 10 , the two front wheels are designed as triangular track wheels 4 .

In this embodiment, forage grass production is carried out, and Baiyan No. 7 is selected for oats, which is a product of Qinghai Lvxinxin Agriculture and Animal Husbandry Technology Co., Ltd.

[0054] The mechanized planting method of corn intercropping with oats includes the following steps: S1. In the autumn of the previous year, the straw of the previous crop was removed from the field and the land was prepared without forming ridges.

[0055] The land can be leveled after the straw of the previous crop is removed from the field in the autumn of the previous year. A rotary tiller can be used to level the land, and no ridges should be formed during land preparation.

[0056] S2. According to the field layout with wheat growth belts and blank belts arranged at intervals, oats are sown flat at the end of March to form the wheat growth belts, and the total width of each wheat growth belt and its adjacent blank belt is 130 cm; in early May, corn is sown in the blank belts without tillage to form corn growth belts, and the adjacent wheat growth belts and corn growth belts are at least 20 cm apart.

[0057] Generally, it is carried out at the end of March. The sowing time in this embodiment is March 28. According to the field layout in which wheat growing belts and blank belts are arranged alternately, oats are sown to form wheat growing belts. The total width of each wheat growing belt and its adjacent blank belt is 130 cm.

[0058] The sowing is performed by flat sowing with the improved seeder described above. In this embodiment, each wheat growth belt is sown with 3 ridges of oats at a row spacing of 15 cm, wherein the "ridge" is also used as a planting row, each wheat growth belt is 40 cm wide, and the blank belt between two adjacent wheat growth belts is 90 cm wide. Base fertilizer is applied while sowing oats. In this embodiment, 15 kg of 45% potassium sulfate compound fertilizer is applied per mu as base fertilizer. The base fertilizer is applied by the seeder while sowing.

[0059] In early May, corn is sown in the blank strip without tillage to form a corn growth strip. The specific sowing time in this embodiment is May 8. Each corn growth strip is sown with 2 rows of corn at a row spacing of 40 cm. Each corn growth strip is 40 cm wide, and the adjacent wheat growth strips and corn growth strips are spaced 90 cm apart.

[0060] Corn sowing is carried out with the 40cm row spacing double-row no-till seeder mentioned above. The machine is equipped with base fertilizer and feed fertilizer boxes. The base fertilizer is applied side-deeply 10cm below the seed, and the feed fertilizer is at the same level as the seed. The base fertilizer, feed fertilizer and sowing are completed in one operation. Corn feed fertilizer: 5 kg of diammonium phosphate per mu. Corn base fertilizer: 50 kg of 51% corn-specific fertilizer per mu. The year in which this embodiment is carried out is not extremely dry, so direct sowing can be done without watering. If it is an extremely dry year, water must be replenished after sowing to ensure emergence. The water replenishment method is: after pulling the water truck, fix a pre-pierced bucket above the corn growth belt, place the water pipe in the bucket, and open the water pipe valve to replenish water to the corn growth belt.

[0061] Field weeding In practice for many years, the wheat growing belt where oats are planted has fewer weeds and no weeding is required. It even achieves the effect of biological weed control between adjacent corn growing belts, and only the corn growing belt needs weeding. The field weeding uses the improved weeder described above, and two nozzles are arranged on the spraying rod, each nozzle is aimed at one of the corn growing belts to spray the herbicide, and a shield is arranged at the position between the spraying rod corresponding to the corn growing belt and the wheat growing belt to ensure that the liquid herbicide will not splash into the wheat growing belt when spraying.

[0062] Weed control is mainly based on closed weeding before corn seedlings after sowing, and weed control after corn seedlings is a remedial measure. ① The herbicides used for closed weeding before corn seedlings after sowing are mainly acetochlor + 2,4-D. butyl ester to control weeds. ② The formula of corn post-seedling herbicides is nicosulfuron + atrazine + mesotrione. In special cases, it can be formulated separately according to the weed situation of the plot. For example, 30% benzathine is used for weed control at 5-8 grams per mu in the 3-5 leaf stage.

[0063] Pest Control The mechanized planting method of corn intercropping with oats also includes the steps of pest and disease control, which are mainly as follows: (1) Underground pests and diseases of corn are mainly controlled by seed coating. (2) During the growing period of corn, the main damage is caused by corn borers. Use Fugo liquid spray to control the damage from the small trumpet to the tasseling stage. (3) If other pests and diseases occur in large numbers, formulate a control plan in real time according to the actual situation in the field.

[0064] S3. During the corn tasseling stage (late June to early July), mechanically harvest oats that are in the late grain filling stage.

[0065] On July 1, 2023, oat grains entered the late filling stage, while corn was in the small trumpet stage. On the morning of July 2, 2023, oats were mechanically harvested and yield measured using the oat or barley harvester interplanted with corn as described above. The harvested oats were rolled into 5 cm small pieces and transported to the field for drying. They were sold after meeting the sale standards.

[0066] The yield measurement method is to take 5 meters of the 130cm wide and narrow row, which is 6.5 square meters. Harvest the oats in the wide row, measure the wet weight and calculate the actual yield per mu. The average of the three points is the final result.

[0067] S4. Harvest corn when it matures (October).

[0068] When the corn milk line disappears and a black layer appears, the corn is harvested at a late maturity. On October 6, 2023, the corn was harvested using the corn harvester described above and the yield was measured.

[0069] The yield measurement method is to take 5 meters of the 130cm wide narrow row, which is 6.5 square meters. Harvest the corn in the narrow row, weigh it and calculate the actual yield per mu. The average of the three points is the final result.

[0070] The adjacent field of the plot planted with corn intercropped with oats was used as a control. The corn plant spacing of the control field was 40 cm × 90 cm, and the corn variety and other corn management measures were the same as those in the mechanized planting method of corn intercropped with oats.

[0071] The yield measurement results of intercropping oats are as follows: 5 meters are taken for the 130cm wide and narrow rows, which is 6.5 square meters. The oats in the wide rows are harvested, and the moisture content of the oats is 79.66%. The values ​​of the three measurement points are: 9.9 kg at the first point, 11.2 kg at the second point, and 11.3 kg at the third point. The yield per mu is calculated to be 1108.2 kg, and the yield per mu is 890.33 kg at a moisture content of 60% (the standard for feed silage sales).

[0072] The yield measurement results of intercropping corn: 5 meters were selected from 3 random points in the 130cm wide and narrow rows, which is 6.5 square meters. The corn in the narrow rows was harvested. The first point was 8.78 kg, the second point was 9.4 kg, and the third point was 9.65 kg. The moisture content of the grains was 36% when threshing. After calculation, the dry grain corn yield was 742.6 kg.

[0073] The yield measurement results of the control corn field without intercropping were as follows: the actual yield at 3 random points was 6.5 square meters, 9.36 kg at the first point, 8.54 kg at the second point, and 10.18 kg at the third point. The moisture content of the grains when threshing was 36%. The dry grain corn yield was calculated to be 749.2 kg.

[0074] Oats are harvested in early July, when corn is in its flaring stage, which has little impact on corn yield in the later period. As a high-quality feed, oats have great market value. Whether it is used as silage or harvested oat grains, the economic benefits are very good. Taking feed as an example, according to the sales standard, feed oats (water content 60%) yield 890.33 kg per mu, the current market price is about 700 yuan per ton, and the income is 623.20 yuan. Excluding the costs of seeds (18.5 yuan), fertilizers (45 yuan), sowing (40 yuan), weeding (25 yuan), harvesting (60 yuan), packaging (89 yuan), short-distance transportation (26) and other costs of 303.5 yuan, the net profit per mu is 319.70 yuan. Corn production decreased by 6.6 kg, with a loss of about 13 yuan, and intercropping oats increased the income by 319.70 yuan, which is a significant increase in efficiency.

If it is an extremely dry year, water must be replenished after sowing to ensure emergence. The water replenishment method is: after pulling the water truck, fix a pre-pierced bucket above the corn growth belt, place the water pipe in the bucket, and open the water pipe valve to replenish water to the corn growth belt.

[0085] Field weeding In practice for many years, the wheat growing belt where barley is planted has fewer weeds and no weeding is required.
