[0002] Grass silkworm is also known as pagoda vegetable, screw vegetable, nectar, ground silkworm, silver bar, etc. In the process of grass silkworm cultivation, single planting and intercropping modes can be adopted. In order to make full use of land resources, growers generally make matching selections based on the planting characteristics and maturity time of inter-ridge crops when intercropping. Usually, the first crop is mostly stalk crops such as wheat, broad beans, and corn. After the stalk crops are harvested, the second crop is planted in the ridges. The second crop can be leafy crops such as cabbage and kale. However, due to the intercropping problem, inter-ridge crops are usually harvested manually, which is labor-intensive and inefficient.

[0030] See also Figures 1 to 6 The present application provides a wheat harvesting and covering device based on the intercropping mode of wheat and grass silkworm, comprising: a machine body 100, a harvesting assembly 400 and a covering assembly 300, wherein at least two wheels 110 are provided at the bottom of the machine body 100; the harvesting assembly 400 is provided at one end of the machine body 100 for harvesting mature wheat between ridges; and the covering assembly 300 comprises a loosening roller 310, a conveying plate 320, a bow shaft 340 and a pressing plate 330, wherein the loosening roller 310 is provided at the bottom of the machine body 100. The conveying plate 320 is arranged behind the loosening roller 310 and is connected to the machine body 100. The conveying plate 320 is used to transport soil and cover it on both sides of the ridge; the bow shaft 340 is connected to the wheel 110 in a transmission manner and is rotatably connected to the machine body 100. The pressing plate 330 is rotatably connected to the bow shaft 340, extends out of the machine body 100 and slides back and forth along the extending direction, and is used to press the newly covered soil on the side of the ridge.

[0031] Specifically, choose fertile soil facing the sun with a deep, loose soil layer and a low groundwater level; turn the soil to form ridges with a width of 0.8 to 1.2 meters, a height of 0.15 to 0.25 meters, and a furrow width of 0.7 to 2 meters; apply base fertilizer to the ridges. From March to April, sow the seeds of the first crop mechanically or manually between the ridges. While wheat is used as the first crop in this application, stalk crops can also be short-stalked crops such as broad beans and peas, or tall-stalked crops such as early-maturing corn. During inter-ridge sowing of the first crop in March, plant the tubers (seeds) of the grass silkworm on the ridges, using a single tuber per hole.

[0032] In early to mid-July, the first crop is harvested mechanically or manually, and soil is covered on both sides of the ridge. The height of the covering soil should not be less than the ridge height, and the crushed straw of the first short-stalked crop is spread on the side of the ridge covered with soil. Wheat is generally harvested in early July. Intercropped wheat can be harvested with a smaller harvester or manually. Manually harvested wheat requires secondary processing, and both the wheat ears and straw need to be transported out of the field. In order to improve efficiency and make full use of the wheat straw, mechanical harvesting is used. The wheat ears are taken away by the machine, and the crushed wheat straw is piled on the side of the ridge covered with soil.

[0033] After the first crop is harvested, the seeds of the second crop are planted between the ridges either mechanically or manually. From October to November, the grass silkworms and the second crop are harvested mechanically or manually, packaged, and stored in cold storage.

[0034] Furthermore, the harvesting component 400 adopts but is not limited to wheat harvesters, straw cutters and other harvesting devices (only mechanical front-end harvesting and transportation equipment is required), preferably a harvesting device that harvests wheat ears first and then harvests wheat straws; by harvesting wheat ears first and then cutting off the wheat straws, laying the wheat straws is more convenient (the wheat straws can also be crushed and then laid on the side of the ridge); the soil covering component 300 adopts but is not limited to tillers, tillers and other plowing machines, all driving devices are arranged in the body 100, and the wheels 110 are provided with at least one transmission wheel and gear A connecting shaft is rotatably connected to the bow shaft 340, and the other end of the connecting shaft is connected to the pressure plate 330. The bow shaft 340 is engaged with the gear on the wheel 110 (the gear is a bevel gear). A circular ring is provided at the end of the connecting shaft away from the bow shaft 340, and a plurality of through holes are provided on the circular ring. An ear plate is provided at one end of the pressure plate 330, and a circular hole is provided on the ear plate. The pressure plate 330 and the connecting shaft are detachably connected together by passing a pin through the circular hole and the through hole, and the inclination angle of the pressure plate 330 is changed by adjusting different through holes, thereby improving its applicability.

[0035] Both ends of the loosening roller 310 are rotatably connected to the support frame of the N-shaped structure, and the support frame is slidably connected to the body 100, and telescopic cylinders are provided at both ends of the support frame. The side walls of the telescopic cylinders are fixedly connected to the body 100, and the telescopic cylinders can be telescoped up and down in the vertical direction. The loosening roller 310 is driven up and down by the telescopic cylinder to move up and down, thereby realizing the adjustment of the height of the loosening roller 310 and the adjustment of the turning depth of the soil. The conveying plate 320 is arranged behind the loosening roller 310 and is slidably connected to the body 100. The shoveling depth and the amount of soil shoveling are adjusted by sliding the conveying plate 320 up and down.

[0036] Furthermore, the wheel 110 carries the body 100 into the ridges, and the harvesting component 400 is turned on to harvest the wheat. The harvesting component 400 harvests the wheat ears and cuts off the wheat straw. The loosening roller 310 located behind the harvesting component 400 loosens the soil and turns out the wheat roots and cuts them. The conveying plate 320 shovels part of the loosened soil and transports it to both sides of the body 100 and lays it on the side of the ridge. The bow shaft 340 drives the pressure plate 330 to extend and retract back and forth when the wheel 110 rotates, and presses the soil covering the side of the ridge, thereby completing the harvesting of wheat between the ridges and covering the grass silkworms with soil.

[0037] This application adopts a technical solution of a wheat harvesting and covering device based on the intercropping mode of wheat and grass silkworm to achieve the following beneficial effects:

[0038] 1. By setting up the harvesting component 400, the problem of low efficiency of manual harvesting is solved, and the labor intensity is reduced at the same time; by setting up the soil covering component 300, the soil between the ridges is loosened and the roots of the wheat are turned out, solving the problems of difficulty in soil collection and subsequent sowing, and at the same time reducing the labor intensity of manual soil covering and improving work efficiency.

[0039] 2. By providing the conveying plate 320, the soil can be transported and the height of the soil can be changed, making it easier and more convenient to cover the ridge side with the soil.

[0040] 3. By providing the bow-shaped shaft 340, the arrangement of the telescopic parts is reduced, making it easier to press the pressing plate 330. Furthermore, by providing the pressing plate 330, the soil covering the ridge side is made denser, solving the problem of soil sliding due to watering.

[0041] Based on the above scheme, the harvesting component 400 includes a wheat harvesting part 410 and a straw transmission part 420. The wheat harvesting part 410 is slidably connected to one end of the body 100, and one end of the straw transmission part 420 is cooperatively connected to one end of the wheat harvesting part 410. The other end of the straw transmission part 420 extends out of the body 100 and is located behind the pressure plate 330, which is used to transport wheat straw and lay it on the side of the ridge.

[0042] Specifically, the wheat harvesting component 410 adopts an ear-throwing wheat harvester and cuts off the wheat straw. The wheat ears are transported to the wheat storage box above the body 100, and the wheat straw falls on the straw transmission component 420 after being cut; wherein, the wheat harvesting component 410 is provided with a lifting cylinder, and one end of the wheat harvesting component 410 is slidably connected to the body 100 through a connecting plate, and the wheat harvesting component 410 is moved up and down by contraction of the lifting cylinder to adjust the height of the cut wheat; the wheat straw transmission component 420 is rotatably connected to the inside of the body 100 and rotated by a motor or a rotating connection. The wheat straw is transmitted from one end of the wheat harvesting component 410 to both sides of the body 100 by the wheat straw transmission component 420, and is laid on the compacted ridge side from the rear of the pressure plate 330. By laying the wheat straw on the ridge side, the problem of rapid water loss in the ridge is solved.

[0043] In the above scheme, in order to improve the convenience of straw covering, the straw transmission part 420 includes a first guide plate 421, a conveyor belt 422 and a second guide plate 423, one end of the first guide plate 421 is arranged below the wheat harvesting part 410; the conveyor belt 422 is arranged at the end of the first guide plate 421 away from the wheat harvesting part 410, the second guide plate 423 is arranged at the end of the conveyor belt 422 away from the first guide plate 421, and the end of the second guide plate 423 away from the conveyor belt 422 extends out of the body 100 and is located behind the pressure plate 330.

[0044] Specifically, the first guide plate 421 is fixedly connected to the body 100, and one end of the first guide plate 421 is flush with one end of the conveyor belt 422 (the conveyor belt 422 can add an auxiliary transmission wheel to change the transmission angle, thereby making its layout simpler and more convenient), the conveyor belt 422 is arranged upwardly at an angle, and the end away from the first guide plate 421 is flush with the second guide plate 423, and the second guide plate 423 is set at an angle. The first guide plate 421 is used to accumulate the straw and enter the conveyor belt, and the second guide plate 423 is used to change the direction of the straw on the conveyor belt 422 and place it on the side of the ridge where the soil has been covered and pressed along the angle of the ridge side, making the operation simpler and more convenient.

[0045] In a preferred embodiment, the conveyor plate 320 includes a scraping plate 321 and a transport belt 322. The scraping plate 321 is slidably connected to the machine body 100 and can slide up and down in the vertical direction. One end of the transport belt 322 is disposed at the end of the scraping plate 321 away from the loosening roller 310, and the other end of the transport belt 322 extends out of the machine body 100 on both sides adjacent to the loosening roller 310. A driving revolver 323 and a driven revolver 324 are disposed at both ends of the transport belt 322. Both ends of the driven revolver 324 are connected to both ends of the scraping plate 321. The driving revolver 323 is rotatably connected to the machine body 100, and the height of the driving revolver 323 above the ground is greater than the height of the driven revolver 324 above the ground.

[0046] Specifically, the two ends of the shovel plate 321 are slidably connected to the body 100 by setting an auxiliary connecting plate, and the width of the shovel plate 321 is not greater than the width of the ridge, and at the same time not greater than the width of the loosening roller 310; Option 1: The shovel plate 321 is tilted and set on the auxiliary connecting plate, and the auxiliary connecting plate is slidably connected to the inner wall of the body 100, and a telescopic rod is set on the auxiliary connecting plate, and the telescopic rod drives the auxiliary plate to slide up and down, thereby realizing the adjustment of the height of the shovel plate 321; Option 2, the two sides of the shovel plate 321 close to one end of the loosening roller 310 are slidably connected to the auxiliary connecting plate through the telescopic rod, and the two sides of the other end of the shovel plate 321 are extended into the auxiliary connecting plate and connected with it The shovel blade 321 is connected in a rotating manner. The extension or contraction of the telescopic rod adjusts the depth of the ridge bottom, thereby adjusting the amount of soil removed. Baffles are provided on both sides of the conveyor belt 322 to prevent excessive soil from scattering from both sides. The driven wheel 324 near one end of the shovel blade 321 is connected to the inner wall of the machine body 100 by sliding or fixed connection depending on the installation method of the shovel blade 321 (Scheme 1 uses a sliding connection, Scheme 2 uses a rotating connection). The driving wheel 323 is higher than the driven wheel 324 from the ground (the driving wheel 323 is driven by a motor), thereby raising the soil height and making transportation more convenient. The shovel blade 321 and the conveyor belt 322 are both located below the conveyor belt and have relatively close inclination angles, thus eliminating the problem of mutual influence.

[0047] Furthermore, the driving wheel 323 is connected to the wheel 110 via a transmission wheel. By providing a transmission wheel at one end of the driving wheel 323, connecting the transmission wheel to the wheel 110 via a belt, and adding a speed change wheel at one end of the wheel 110 or the driving wheel 323 to adjust the rotation speed of the transport belt 322, the operation is simpler and more convenient, and the layout of the motor is reduced.

[0048] In the preferred solution, in order to achieve the purpose of non-destructive soil covering, a seedling supporting component 200 is also included. The seedling supporting component 200 is arranged on both sides of the body 100 and moves with the body 100 to straighten the stems and leaves of the grass silkworm on the side of the ridge from a crawling state to a standing state.

[0049] Specifically, the seedling supporting component 200 adopts but is not limited to an angled structure such as an arc-shaped plate, an inclined plate with a gradient angle, and the seedling supporting component 200 is arranged above the soil covering component 300. The seedling supporting component 200 extends into the gap between the stems and leaves of the grass silkworm through the front end, and lifts the stems and leaves of the grass silkworm away from the side of the ridge through the seedling supporting component 200, thereby solving the problem of damage to the stems and leaves of the grass silkworm caused by covering with soil, pressing and covering with wheat straw.

[0050] Based on the above scheme, the seedling supporting assembly 200 includes an insertion plate 210, a transition plate 220 and a straightening plate 230. One side of the insertion plate 210, the transition plate 220 and the straightening plate 230 are hinged on the side wall of the body 100, and the other side is inclined upward; one end of the insertion plate 210 extends out of the end of the body 100 close to the loosening roller 310, and can extend into the gap between the ridge side and the stems and leaves of the grass silkworm; one end of the transition plate 220 is fixedly connected to the end of the insertion plate 210 away from the loosening roller 310, and one end of the straightening plate 230 is connected to the end of the transition plate 220 away from the insertion plate 210, and the other end extends out of the end of the body 100 away from the loosening roller 310.

[0051] Specifically, the length of the insertion plate 210 can be adjusted according to the crawling situation of the grass silkworm, and can be extended by detachable means such as bolts; for example, one side of the insertion plate 210 is connected to the side wall of the body 100 by using a rotating shaft 424 or a hinge (if the rotating shaft 424 is used, a gear and a card plate are installed to fix the angle, the gears are set at both ends of the insertion plate 210, and the card plate is hinged under the rotating shaft 424 to control the angle of the insertion plate 210 by snapping; if a hinge is used, a limit hinge is used to control the insertion plate 210 and the side wall of the body 100); the straightening plate 230 and One side of the transition plate 220 is connected in the same way as the insertion plate 210, and the transition plate 220 is arranged between the insertion plate 210 and the straightening plate 230, and the inclination height of the insertion plate 210, the transition plate 220 and the straightening plate 230 away from the side of the body 100 gradually increases, and the scraper 330 extends from the end of the straightening plate 230 away from the transition plate 220. By gradually increasing the angle, the stems and leaves of the grass silkworm follow the angle change of the seedling supporting component 200 and gradually straighten away from the ridge side when the body 100 moves, thereby solving the problem of covering the stems and leaves of the grass silkworm when covering the soil.

[0052] Based on the above solution, in order to achieve the purpose of integrated harvesting and sowing, a sowing assembly 500 is further included. The sowing assembly 500 is arranged at one end of the body 100 away from the harvesting assembly 400 and is used for sowing crops.

[0053] Specifically, the sowing component 500 adopts a common seeder. After the harvesting component 400 located at the front end of the body 100 collects the wheat, the loosening roller 310 loosens the land between the ridges and cuts the roots of the wheat. After the conveying plate 320 shovels the required soil, it indirectly levels the ridges. The seeder located at the rear of the body 100 directly sows in the prepared soil, thereby achieving integrated harvesting and sowing, reducing labor while improving work efficiency.

[0054] The above-described embodiments only express the way in which the equipment of the present application is arranged. The description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application. It should be pointed out that a person skilled in the art can make a number of adjustments and improvements without departing from the concept of the present application, and these all fall within the scope of protection of the present application. Therefore, the scope of protection of the patent of the present application shall be based on the attached claims.
