Description

Technical field

[0001] The utility model relates to a grain harvesting device, in particular to a harvesting, sowing and straw covering all-in-one machine which can sow seeds of a mature crop while harvesting and cover the straw evenly and comprehensively. Background Art

[0002] At present, harvesters can only accomplish the simple purpose of harvesting grain. The fallen straw forms ridges and piles, which causes great trouble for the next crop farming. Deep plowing, soil splitting, raking and sowing are required, which increases various agricultural costs and carbon emissions. Moreover, turning the deep raw soil to the upper layer is not conducive to crop growth, thereby increasing the use of chemical fertilizers. Summary of the Invention

[0003] In order to overcome the above-mentioned shortcomings, the utility model adds a seeder, an extra-long straw thrower, and a full-width uniform grass spreading plate on the basis of the existing harvester, so as to achieve the purpose of harvesting and sowing grass at the same time, and then enters the germination management, thereby greatly reducing various costs, carbon emissions and fertilizer application.

[0004] The technical solution adopted by the utility model to solve its technical problems is as follows: A seeder is installed on the outer side of the upper part of the tail of the harvester by means of suction and additional suspension. The shape of the seeder is a rectangular bracket. Bearings are fixed at both ends of the bracket base. A large shaft is installed on the bearings. Scrapers are fixed on the large shaft. One end of the large shaft is connected to an electric motor, and the electric motor is fixed on the support plate. A pipe connection groove is fixed on the base on one side below the large shaft. The end of the seed delivery pipe is inserted into the hole on the pipe connection groove, and the position of the hole corresponds to that of the scraper. A seed bin is installed from above the large shaft to the upper part of the bracket. A seed outlet is opened at the bottom of the seed bin to allow seeds to flow above the large shaft. For the convenience of drawing, it is assumed that the seed bin is made of transparent fiberglass, and only the dotted outline can be seen. A U-shaped long brush is installed at the lower edge of the seed bin, and the hair end of the brush presses on the large shaft. When the large shaft rotates, the scraper scrapes the seeds and overcomes the obstruction of the brush end to scrape out the seeds. The scraped seeds fall into the corresponding end of the seed delivery pipe below and slide. The seed delivery pipe passes through both ends of the ultra-long straw flicker below and then to both sides of the full-width uniform straw spreading board at the bottom. Then, it is fixed to the vertical fixing board of the full-width uniform straw spreading board according to a certain slope distribution, and then passes through the holes on the fixing board and then runs to the vicinity of the lower front corner of the straw spreading piece that is perpendicular to the vertical fixing board but slopes downward at a certain slope, and then the seeds fall. The ultra-long straw flicker is fixed in the ear hole in the middle of the inner side of the tail of the harvester. In the front-back direction with the head of the harvester as the front and the tail as the back, a fixed shaft or fixed pipe is fixed in the front pair of ear holes. A fixing board is penetrated on the shaft or pipe. A working shaft is penetrated in the rear hole of the fixing board, and the other end of the working shaft penetrates into the corresponding rear ear hole of the harvester. A working pipe is sleeved on the working shaft, and a拨动杆 (the specific name needs to be further determined according to the actual situation) is fixed at the other end. Multiple flicking rods are fixed on the working pipe, a blocking needle is fixed at one end, and a return spring is fixed at the other end. The working shaft is connected to the main shaft of the electric motor, and the electric motor is fixed to the fixing board. When the electric motor rotates, the拨动杆 hits the blocking needle and带动拨甩杆 (the specific name needs to be further determined according to the actual situation) to rotate. When the flicking rod is blocked by the rear shell of the harvester, the current of the electric motor is zero, and it falls back under the action of the return spring to complete the task of flicking the ultra-long straw. The width of the full-width uniform straw spreading board is consistent with the actual harvesting width of the harvester cutting table (knife). It is composed of more straw spreading pieces distributed on the vertical fixing board of the full-width and having sufficient holes to freely adjust the relative positions.

[0005] The beneficial effects of the utility model are that sowing and covering grass are carried out simultaneously during harvesting, without the need for tilling and sowing or transplanting seedlings, and then entering the germination promotion management, thus greatly reducing various costs, carbon emissions and the application amount of chemical fertilizers.

Specific implementation mode

[0011] Note: For "拨动杆", since there is no exact English term provided, "toggle rod" is used as a tentative translation. It may need to be adjusted according to the actual context.In the figure, a seeder (2) is installed on the outer side of the upper part of the rear of the harvester (1) by means of suction and additional suspension. The seeder (2) has a rectangular parallelepiped-shaped bracket (3). Bearings (5) are fixed at both ends of the bracket base (4). A large shaft (6) is installed on the bearings (5). Scrapers (7) are fixed on the large shaft (6). One end of the large shaft (6) is connected to a motor (8). The motor (8) is fixed on a support plate (9). A pipe connection groove (10) is fixed on the base (4) on one side below the large shaft (6). The end of the seed delivery pipe (11) is inserted into the hole on the pipe connection groove (10). The hole corresponds to the position of the scraper (7). A seed storage (12) is installed from above the large shaft (6) to the upper part of the bracket (3). For the convenience of drawing, it is assumed that the seed storage (12) is made of transparent fiberglass and only the dotted line contour can be seen. A U-shaped long brush (13) is installed on the lower edge of the seed storage (12). The hair end (14) of the brush (13) presses on the large shaft (6). When the large shaft (6) rotates, the scraper (7) scrapes the seeds and overcomes the obstruction of the hair end (14) to scrape out the seeds. The scraped seeds fall into the corresponding end of the seed delivery pipe (11) below and slide. The seed delivery pipe (11) passes through both ends of the ultra-long straw flicker (15) below to the vertical fixing plate (17) of the full-width uniform straw spreading plate (16) at the bottom, then penetrates into the hole on the fixing plate (17) and then runs to the vicinity of the lower front corner of the straw spreading piece (18) that is perpendicular to the vertical fixing plate (17) but slopes downward at a certain gradient and then the seeds fall. The ultra-long straw flicker (15) is fixed in the ear hole (20) inside the middle part (19) of the rear of the harvester. Taking the front of the harvester as the front and the rear as the rear, a fixed shaft or a fixed pipe (or the fixed pipe is sleeved on the fixed shaft) (21) is fixed in the front pair of ear holes (20). A fixing plate (22) is penetrated on the fixed shaft or the fixed pipe (21). A working shaft (23) is penetrated in the rear hole of the fixing plate (22). One end of the working shaft (23) penetrates into the corresponding rear ear hole (20) of the harvester. A working pipe (24) is sleeved on the working shaft (23). A拨动杆(25) is fixed at the other end. Multiple flicking rods (26) are fixed on the working pipe (2)4. A blocking needle (27) is fixed at one end and a return spring (28) is fixed at the other end. The other end of the working shaft (23) is connected to the main shaft of the motor (29). When the motor (29) rotates, the拨动杆(25) hits the blocking needle (27) to drive the flicking rod (26) to rotate. When the flicking rod (26) is blocked by the rear shell of the harvester, the current of the motor (29) is zero. Under the action of the return spring (28), it falls back to complete the task of flicking the ultra-long straw. It should be noted that there is an unclear "拨动杆" in the original text which may need to be further clarified for a more accurate translation. Here it is tentatively left as is.
