Abstract

The utility model relates to an improved grain seeder which comprises a seeder frame, road wheels, colter boots and a seeding device, wherein the road wheels are arranged on both sides of the rear part of the seeder frame; a horizontal axis is arranged under the bottom surface of the front part of the seeder frame; connecting arms with the colter boots are uniformly hinged on the horizontal axis at intervals. The colter boots are positioned between the road wheels and the horizontal axis. The seeder frame is provided with a transverse rotary axis by a pillar above the rear parts of the colter boots. The rotary axis is alternately and uniformly fixedly connected with rocking arms which extend towards the front part of the seeder frame, and the rocking arms and the rotary axis are perpendicular to each other. The free end of each rocking arm is hinged with a sliding bush, and a guide rod is glidingly sheathed in each sliding bush; the lower ends of the guide rods are hinged together with the rear ends of the connecting arms of the colter boots. Compression springs are sheathed on the guide rods between the colter boots and the sliding bushes. The utility model has strong adaptability to terrain, and can automatically adjust the depth of a furrow according to the fluctuation of the ground, and the depth of the furrow is matched with the fluctuation of the ground. Accordingly, the phenomenon of the irregular emergence of grain seedlings caused by the uneven depths of the furrow is thoroughly eliminated.

Description

Improved grain seeder

Technical field

The utility model belongs to the improvement of grain seeder tool, particularly improved grain seeder.

Background technology

At present, along with the raising day by day of agricultural mechanization degree, increasing place begins to popularize grain seeder, replaces the by artificial seeding with machinery, and not only speed of drilling is fast, sowing efficient height, and can save a large amount of seeds, peasant's labour intensity is little.Its weak point is, prior to seeding, rack-mounted plough be adjusted in advance, and the degree of depth of ditching in the process of sowing is fixing so generally can not change easily.This arable land for a wide expanse of flat land is comparatively suitable, but for the arable land of surface relief injustice since the comparatively fixing ditch depth that directly causes leaving of plough differ, cause existing sower poor to the adaptive capacity of landform, the crop seeds such as cereal that therefore cause easily sowing are emerged uneven or some places are emerged, and some places are not emerged.

Summary of the invention

The purpose of this utility model is to provide a kind of improved grain seeder, its adaptive capacity to landform is strong, can adjust the trench digging degree of depth automatically according to the fluctuating on the face of land, the fluctuating situation on the trench digging degree of depth and the face of land is complementary, thereby thoroughly eliminates because of the deep mixed cereal that causes of the degree of depth of the ditching uneven phenomenon of emerging.

The purpose of this utility model is achieved in that a kind of improved grain seeder, comprise frame, road wheel, plough and dispenser, road wheel is installed in the both sides, rear portion of frame, horizontal trunnion axis under the bottom surface of frame front, the articulated uniformly at intervals linking arm that has plough on this trunnion axis, plough is between road wheel and trunnion axis, on the frame above the plough rear portion, a horizontal rotating shaft is installed by column, affixed uniformly at intervals the rocking arm that stretches towards frame the place ahead on this rotating shaft; rocking arm is vertical mutually with rotating shaft; all articulated sliding sleeve of the free end of rocking arm; the suit that all slides in each sliding sleeve guide rod; the rear end of the lower end of guide rod and plough linking arm is hinged, and suit the compression spring on the guide rod between plough linking arm and the sliding sleeve.

When the utility model uses, frame is installed in the afterbody of dynamic power machines such as tractor, according to the surface relief situation that will sow, be rotatably installed in the rotating shaft on the framework pillar earlier, make on it rocking arm free end of installing raise or reduce, thereby the compression spring that is sleeved on the guide rod in the sliding sleeve is carried out suitable pretension, so that plough is applied certain active force downwards by the compression spring.When the face of land downwards during low-lying going, the compression spring will be with plough to pressing down, and makes the plough can dark as far as possible trench digging; When the face of land raised up, plough will move upward, and the compression spring again can be by upwards compression of plough, and elastic force increases, and it is too shallow that the ditch that plough is left is unlikely to.Like this under the effect of compression spring, plough just can be accomplished to adapt with the fluctuating situation on the face of land when trench digging work, no matter the face of land is high rises or low-lying, can leave the moderate ditch of the depth, abandoned and used the fixedly fixing pattern of the plough trench digging degree of depth in the past, its adaptive capacity to landform is strong.Plough of the present utility model can be adjusted the trench digging degree of depth according to the fluctuating on the face of land automatically for floating Installation Modes, and the trench digging degree of depth and the fluctuating situation on the face of land are complementary, thereby thoroughly eliminates because of the deep mixed cereal that causes of the degree of depth of the ditching uneven phenomenon of emerging.

Embodiment

A kind of improved grain seeder as shown in Figure 1 and Figure 2, comprises frame 9, road wheel 2, plough 8 and dispenser 6, and the front portion of frame 9 is installed with the link that matches with dynamic power machines such as tractors.Road wheel 2 is installed in the both sides, rear portion of frame 9, uniform on the wheel rim of road wheel 2 upright tabular tooth is being set, so that increase the frictional force between road wheel 2 and the ground.Horizontal trunnion axis 10 under the bottom surface of frame 9 front portions, the articulated uniformly at intervals linking arm 12 that has plough 8 on this trunnion axis 10, plough 8 is between road wheel 2 and trunnion axis 10.

As shown in Figure 2, between the plough 8 at left and right two ends apart from degree greater than the distance between two road wheels 2.Monoblock is ploughed can both be helped helping eliminating the dead angle of water furrow planting at the splat upper seeding wheel by water furrow planting.

On the frame 9 above plough 8 rear portions, a horizontal rotating shaft 3 is installed by column, affixed uniformly at intervals the rocking arm 13 that stretches towards frame the place ahead on this rotating shaft 3, rocking arm 13 is mutual vertical with rotating shaft 3.The all articulated sliding sleeve 4 of the free end of rocking arm 13, the free end of rocking arm 13 has a U-shaped prong, and sliding sleeve 4 is hinged in this prong.The suit that all slides in each sliding sleeve 4 guide rod 5, and the rear end of the lower end of guide rod 5 and plough linking arm 12 is hinged, and suit compression spring 11 on the guide rod 5 between plough linking arm 12 and the sliding sleeve 4.
