Description
Technical Field
The invention relates to the field of agricultural machinery, in particular to a hand-push type single-corn hill planter.
Background
Currently available corn sowing equipment is broadly divided into three categories: the large-scale sowing machine driven by the power machine is suitable for large-scale farming machine operation, such as corn drill sowing machine, which has high sowing speed, high efficiency and guaranteed sowing quality, but is only suitable for plain areas (such as northeast and river cover areas); the other type is a seeder which is formed by combining the separate functions of a furrow opener, a seed box, a land wheel and the like, and the seeder box body, the land wheel and the furrow opener are integrated, so that the number of the connecting wheels is large, the machine is complex, and the seeder is inconvenient to carry and popularize to farmers; the other type is manual insertion dibbling, and compared with the traditional sowing mode, the method has no fundamental improvement, and is time-consuming, labor-consuming, low in speed, low in efficiency and high in labor intensity; the existing mechanical equipment can not meet the sowing requirements for mountain cultivated lands, slope cultivated lands and small-block cultivated lands, and people can also adopt the most original manual insertion dibble seeding for corn sowing; for the land inconvenient for large-scale machinery to sow corn, such as mountain land, slope land and small-scale land, the development and design of novel sowing equipment are imperative.
Through patent literature search, related art documents are:
(1) The Chinese patent with publication number CN2171193Y discloses a hand-pulled portable no-tillage planter, which consists of a land wheel 1, a seed box 11, a shaft 12 and a hand-pulled control rod 13 (the detailed structural description is shown in the specification); the sowing process of the sowing machine is as follows: firstly, seeds are put into the seed box 11, the sowing port cover plate 7 of the automatic sowing inserter 3 is in a closed state before sowing, the sowing machine is pulled to rotate forwards, when the seed extractor 15 moves to the lower part of the seed box 11, the seeds are automatically extracted, the land wheel 1 presses and inserts the automatic sowing inserter 3 into a field through the self weight of the main body, the insertion depth is controlled by the depth extractor 2, and the insertion is stopped after the depth reaches. At the same time, seeds are removed by the seed extractor 15 and slid through the seed metering channel 14 into the seed opening 6 of the automatic sowing inserter 3. With the continuing rotation of the main body of the land wheel 1, the resultant force extrusion action of the ground surface and the depth setting device 2 on the land wheel 1 causes the spring 4 to compress, the sowing port cover plate 7 is opened, the inserter spits out seeds, with the continuing rotation of the land wheel 1, the inserter automatically dials out, the sowing port cover plate 7 is rebounded to a closed state, once insertion sowing is completed, and the land wheel 1 is pulled for a circle to continuously complete four times insertion sowing. The detailed structure of the seed extractor 15 is not described in this technical solution, and it is not clear how to automatically extract seeds.
(2) The Chinese patent with the authorized bulletin number of CN2503690Y discloses a paddy rice and corn hill planter; the novel duckbill seed metering device comprises a handle (6), a push rod (5), a seed metering disc (3), a duckbill seed metering port (2), a spring pressing plate (7), a spring (1) and a rotating shaft (4), wherein the handle (6), the push rod (5) are connected with the rotating shaft (4) on the seed metering disc (3), the duckbill seed metering port (2) and the spring (1) are fixedly connected onto the seed metering disc (3), and the spring pressing plate (7) is connected with a movable door on the duckbill seed metering port into a whole. The specific operation process is as follows: the pushing force pushes the hill planter to advance, the hill planter wheel (seed metering disc) and the ground generate resistance, so that the hill planter wheel rotates, the duckbill is inserted into soil for punching, meanwhile, the spring is pressed by the grounding pressure of the spring pressing plate, the duckbill is forcedly opened, seeds are sowed into the hill through the duckbill channel, the hill planter wheel continuously rotates, the spring pressing plate leaves the ground, and the duckbill is closed under the action of spring force, so that the whole seed sowing process is completed. The technical scheme does not describe the detailed structure of the seed metering disc (3), how the internal structure is installed and how the seed metering disc is installed, and how to take seeds is not very clear.
(3) The Chinese patent with the authorized bulletin number of CN104115598B discloses a corn precise seed metering device which comprises a seed taking device, a duckbill mounting frame (1), a duckbill dibbler (4) and a seed metering device side guard plate (9) (the detailed structure is shown in the specification), wherein the corn precise seed metering device is arranged on a seeder for use, and the single seed sowing precision can be realized.
Along with the development of precise agricultural technology, the requirement on sowing is higher and higher, and precise sowing becomes a very critical technology, but the current sowing mechanism is difficult to adapt to the development requirement; therefore, the inventor sets and manufactures a hand-push type single-grain corn hill planter which is used for mountain cultivated lands, slope cultivated lands and small-block cultivated lands which are inconvenient for large-scale machinery to carry out corn sowing, and solves the problem that the lands are manually dibble; and realize accurate waiting plant spacing single seed seeding through institutional advancement, through the field use, this hill-drop planter is easy and simple to handle laborsaving, can realize the accurate seeding of single seed of maize, can not appear leaking and many seed and get kind phenomenon hardly.
