Description

Rice seeder

The utility model relates to a kind of agricultural mechanical field, exactly is rice seeder.

What the peasant carried out paddy rice plantation employing for many years is conventional method all the time, be to insert after the seedling to plant, though this original planting patterns has the alternative artificial work of mechanical rice planter, but machine rice transplantation is subjected to the restriction of orographic condition in many areas, machinery needs great amount of investment in addition, therefore, the peasant have to adopt traditional rice of manually planting.

The purpose of this utility model be the design a kind of small-sized rice sower that is suitable for big small size, different terrain conditions, seed place hopper at the sower traveling process with seed sowing in the field.

For achieving the above object, the technical solution adopted in the utility model is: rice seeder, be associated with wheel shaft between the centre of gyration of its two road wheels, the wheel shaft upper support connects hopper, hopper links to each other with handgrip, the hopper lower end is provided with the slide plate smoothly mobile with respect to its lower end feed opening that promoted by the road wheel rotational power, when slide plate moves, the plate hole of being opened on it can be in position and this two kinds of location status cycle alternations appearance of aiming at or misplacing with above-mentioned feed opening respectively, when dislocation, the seed of getting that amasss dropped down onto in the field when plate hole will be aimed at feed opening.

In the utility model, the slide plate of establishing as feed opening place, powered hopper lower end with the rotation of road wheel moves, the plate hole of being opened on the slide plate therefrom obtains seed when aiming at feed opening, the seed that is held in it when moving to the dislocation state then just self seed in the field, when road wheel advances, will repeat plate hole aims at feed opening or the dislocation state, seed just quantitatively is seeded in the whole field to spacing, the utlity model has and be suitable for greatly, small size, advantages such as the farmland use of different terrain conditions, owing to be the seed sowing sowing, can avoid the generation of the injured phenomenon of shoot transplanting equipment, therefore, help per mu yield output and improve, also can the corresponding shortening maturing stage.

The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment

In Fig. 1 as seen, be connected with wheel shaft (20) between the centre of gyration of two road wheels (10), wheel shaft (20) upper support is connecting hopper (30), hopper (30) links to each other with handgrip (90), during pulling handgrip (90), whole sower just carries out, hopper (30) is to be made of several bucket bodies that are distributed in wheel shaft (20) length direction, each hopper body below is provided with a slide plate (40), slide plate (40) is subjected to road wheel (10) rotational power to promote smoothly to move with respect to feed opening (31), in the moving process, the plate hole of being opened on it (41) can be in the position of aiming at or misplacing with above-mentioned feed opening (31) respectively, and these two kinds of location status cycle alternations occur, and when dislocation, the seed that plate hole (41) will be obtained in the time of will aiming at feed opening (31) casts in the field.

Referring to Fig. 2, Fig. 3, slide plate (40) is positioned at the chute (51) that constitutes between feed opening (31) end face of hopper (30) and the base plate (50), the direction of chute (51) is consistent with the direction of translatory motion of wheel shaft (20), shown in A portion among Fig. 2, B portion signal then is the status architecture that adds behind the base plate (50) among Fig. 2, slide plate (40) connects firmly with rod member (60), rod member (60) is positioned at wheel shaft (20) side and match with the inboard set pushing block (12) of road wheel (10) respectively in its two ends, pushing block (12) is with road wheel (10) rotation process discontinuous formula contact and promote rod member (60) and slide plate (40) moves along the direction that chute (51) is limited, and spring (70) pulling slide plate (40) makes it finish the reseting movement that plate hole (41) is aimed at feed opening (31).

Referring to Fig. 1, Fig. 2, Fig. 3, road wheel (20) is gone up set pushing block (12) for several and be distributed on the spoke place of road wheel (10), one arc surface (13) that is parallel to wheel shaft (20) is arranged on the pushing block (12), this arc surface (13) two ends to the distance of wheel shaft (20) does not wait, one end of this arc surface (13) begins to contact with rod member (60) in the whole contact process that disengages to the other end, and the translation distance that promotes rod member (60) and slide plate (40) should be as the criterion to guarantee that plate hole (41) be sowed with feed opening (31) dislocation and with seed; Spring (70) is extension spring, and its two ends link with slide plate (40) and hopper (30) respectively and spur slide plate (40) reseting movement, and in Fig. 3, member (32) is to connect firmly with hopper (30), and an end of spring (70) is coupled.Arc length between the pushing block (12) is the distance between the rice strain front and rear row just, and this distance can be determined by rice cultivating technique.

As seen from Figure 2, slide plate (40) is to connect firmly one by the rod member (62) that connects firmly mutually, (63) transition and rod member (60), and like this, in case rod member (60) motion, slide plate (40) is and then motion also.Two rod members (80) are set parallel to each other on the isometry position of hopper (30) bottom, they pass from set hole, rod member (60) two ends and are vertical with rod member (60), and the purpose that adds rod member (80) is in order to improve the stability of rod member (60) and slide plate (40) translation.Spacing between the slide plate (40) equals the spacing with the strain of draining rice rice just, and it can be determined by rice cultivating technique.
