Description
Technical Field
The invention relates to the technical field of agricultural machinery, in particular to a double-shaft rotary tillage fertilizing and seeding machine.
Background
With the development of science and technology, agricultural machinery plays an increasingly important role in the production and life of people. As is known, a no-tillage planter is a planter for directly planting seeds on the soil which is not ploughed, and can make the machine replace the original manpower to complete the procedures of planting, fertilizing, ploughing and the like in one step. The method is particularly applied to economic crops suitable for large-scale planting such as corn, soybean, potato, garlic and the like. Mainly aims to solve the problems of insufficient labor and labor cost in rural areas and enlarge the agricultural planting area and the mechanization level. It has the functions of preventing soil erosion and water loss, preventing sand and dust, protecting environment, saving energy, reducing consumption, and robbing farming season, etc., so it is more and more paid attention.
At present, protective farming is approved by most countries and is experimented and popularized, and in recent years, various protective farming technologies in different forms such as no-tillage, less-tillage, shallow-scarification and the like are popularized in a large area in China. The no-tillage planter is a protective farming agricultural machine which is widely popularized and applied in recent years, and a series of problems such as soil moisture leakage and the like caused by the fact that ground straws and weeds cannot cover the no-tillage planter also occur along with the application of the no-tillage planter.
And because the soil humidity degree of the farmland is different and the crushing degree of the straw returned to the field is different. Sowing machines on the market present two problems during the operation: (1) the soil is moist, so that soil is fully adhered to a land wheel for transmission seeding, normal transmission cannot be realized, the seeding is not uniform, even the problems that the fertilizing and seeding machine cannot continue to operate and the like can occur when the humidity is too high, and fertilizing and seeding operation can be performed after the soil is dried; (2) the situation that the seeding cannot be normally sown can be caused because the straw returned to the field entangles the seeding legs.

When the first fertilizer bin 46 of needs exclusive use, can unscrew the screw, expand folded sheet 49 toward first seed storehouse 45 direction, make its lid establish on first seed storehouse 45 cang kou, twist the screw into the corresponding screw hole on folded sheet 49 and the stopper 47, can dismantle the connection with the two, can carry out fertilization work alone this moment. The first fertilizer bin 46 of the present invention is relatively large and therefore does not require frequent feeding of fertilizer into the first fertilizer bin 46 during use. Greatly reducing the labor intensity of workers and improving the working efficiency.
EXAMPLE III
The invention discloses a double-shaft rotary tillage fertilizing and seeding machine, and the structure of the machine is the same as that of the first embodiment except for a seed and fertilizer box. Referring to fig. 10 and 11, a schematic structural view of a third embodiment of the present invention and a partially enlarged view of the third embodiment of the present invention at the position B are shown, respectively, and the third fertilizer box body 23, the upper filter cover 52 and the gas spring 53 are included. Both ends of a side edge of the upper filter screen cover 52 are rotatably connected with the third fertilizer box body 23 through fixing blocks, one end of each fixing block is fixedly connected with the third fertilizer box body 23 through screws, and the other end of each fixing block is rotatably connected with a frame of the upper filter screen cover 52 through a hinged bolt. The upper cover 52 of the filter screen is turned over relative to one side of the third fertilizer box body 23 through the fixing block. The upper cover 52 of the filter screen is composed of a frame and a filter screen, and both the frame and the filter screen are made of metal materials. The filter screen is stuck on the frame and is fixedly connected with the frame. The aperture of the filtration pore that sets up on the filter screen is 20mm, and the clearance of filtering between the pore is 1.25mm, and the less seed of holding volume or fertilizer of the aperture of filtering the pore can block some great impurity of volume and bold fertilizer outside, prevents to cause the seed manure case to block up, hinders machine normal operating. The gas springs 53 are arranged on the left side and the right side of the filter screen upper cover 52 and are adjacent to the fixing blocks. One end of the gas spring 53 is rotatably connected with the third fertilizer box body 23 through a hinge bolt, and the other end is rotatably connected with the filter screen upper cover 52 through a hinge bolt. When the filter screen upper cover 52 is opened upward, the gas spring 53 plays a role of supporting the filter screen upper cover 52, and the supporting force of the gas spring 53 is constant in the process that the whole filter screen upper cover 52 makes an overturning motion, and the gas spring is provided with a buffer mechanism which can avoid in-place impact and play a role of buffering.
Referring to fig. 12, a schematic view of a third fertilizer box body is shown, a third fertilizer bin 55 and a third sub-bin 54 are arranged in the third fertilizer box body 23, the third fertilizer bin 55 and the third sub-bin 54 are separated by a partition plate 56, the left side, the right side and the lower side of the partition plate 56 are fixedly connected with the contact part inside the seed fertilizer box body through screws, a fertilizer outlet is arranged in the third fertilizer bin 55, and a seed outlet is arranged in the third sub-bin 54.
During the use, pour fertilizer or seed on filter screen upper cover 52, cross fertilizer by the filter screen on the filter screen upper cover 52 and filter the seed, in small seed or fertilizer can leak into third kind fertile case body 23 in following the filtration pore, derive by fertile mouthful or the mouth of sowing again. Some labels, impurity and bold fertilizer are stopped outside the seed manure case promptly, can press the bold fertilizer and drag on the filter screen, can break it open, when needs open filter screen upper cover 52, and air spring 53 can support filter screen upper cover 52, makes its holding position motionless.
When the machine works, the gear box 2 drives the cutter shaft 12 to rotate to cultivate the field, and the mud guard 17 can prevent soil from lifting the rotary tillage cutter 7 when the machine works from sliding down along the surface of the mud guard 17, so that the soil is prevented from being adhered to the machine and hindering the operation of the machine. The bent seed legs 11 can discharge seeds or fertilizers into the field, the gear boxes 2 also drive the side gear boxes 3 to drive the grass and mud discharging knives 7 to rotate, and the fly knives 2 arranged on the grass and mud discharging knives 7 can cut and throw away the weeds wound on the bent seed legs 1 and the sticky soil, so that the influence of impurities such as straws wound on the bent seed legs 11 on the operation of the machine is prevented. The machine drives the land wheel 13 to roll forwards while running forwards, and the land wheel 13 used for driving seeding is often stained with soil and cannot normally drive due to the fact that soil is wet, and the seeding is not uniform. When the soil humidity is too big, the problem that the fertilizing and seeding machinery can not continue to operate can even appear, and the fertilizing and seeding operation can be carried out after the soil is dried. The mud scraper device 10 of setting in land wheel 13 top can in time clear away the earth that glues on the land wheel 13, and the laminating is on the land wheel 10 surface below the shovel mud board 9, can be when the operation of land wheel 10 roll, and the synchronous is in time effectual cleaing away the impurity such as the earth weeds that the land wheel 10 adheres to on the surface in the course of the work. Therefore, the invention can work continuously and efficiently under any conditions, has strong site adaptability and better use effect.
