Technical Field

[0001] The invention relates to the technical field of seed drills, and in particular to a quinoa seed drill. Background Art

[0002] Chenopodium quinoa Willd. is a plant of the genus Chenopodium in the Chenopodium family. The spike can be red, purple or yellow, and the shape of the plant is similar to that of gray cabbage. When mature, the spike resembles a sorghum spike. The size of the plant is greatly affected by environmental and genetic factors, ranging from 0.3 to 3 meters. The stem is hard and may or may not be branched. The leaves are single and alternate, and the leaves are in the shape of duck feet. The leaf margins are divided into the entire type and the serrated type. There are two types of quinoa flowers, and the inflorescence is umbrella-shaped, spike-shaped, and conical. The seeds of quinoa are small, in the shape of small round pills, with a diameter of 1.5 to 2 mm and a thousand-grain weight of 1.4 to 3 grams.

DETAILED DESCRIPTION

[0019] To facilitate those skilled in the art to understand the present invention, specific implementations of the present invention are described below with reference to the accompanying drawings.

[0020] like Figures 1 to 5 As shown, the present invention provides a quinoa seeder, comprising a frame 1, which is connected to the body of the seeder through a lifting mechanism, a plurality of vertical rails 2 are fixedly installed on the rear side of the frame 1, and vertical pipes 4 are arranged on the rear sides of the vertical rails, a soil turning part 3 is fixedly installed at the position corresponding to the vertical pipe 4 at the bottom of the frame 1, the vertical pipe 4 is connected to the vertical rail through a slider, a C-shaped frame 5 is fixedly installed on the side of the vertical pipe 4, and also comprises a transverse axis 6, an eccentric wheel 7 is fixedly installed on the transverse axis 6, the eccentric wheel is arranged inside the C-shaped frame, the transverse axis is connected to the driving structure of the seeder, and when the transverse axis rotates, the vertical pipe 4 can be driven to reciprocate up and down through the cooperation of the eccentric wheel and the C-shaped frame, an inclined pipe 8 is connected to the rear side of the vertical pipe near the lower end, the lower end of the inclined pipe 8 is communicated with the inside of the vertical pipe, the upper end of the inclined pipe 8 is connected to the sowing box through a hose 9, and quinoa seeds are contained in the sowing box, a partition 10 vertically passing through the inclined pipe is arranged near the lower end of the inclined pipe, and the upper end of the partition 10 is fixedly connected to the frame through a bracket.

[0021] The soil turning part moves forward with the seed drill to turn up the soil and make the soil loose. The driving structure drives the eccentric wheel to rotate. The cooperation between the eccentric wheel and the C-shaped frame can drive the vertical pipe 4 to move up and down. When the vertical pipe moves downward to the lower limit position, the lower end of the vertical pipe is inserted into the loose soil. At this time, the lower end of the partition 10 is located in the inclined pipe near the upper side. Figure 5As shown, at this time, several seeds can enter the vertical tube through the lower side of the partition and fall into the loose soil at a relatively accurate depth through the lower end of the vertical tube. After the vertical tube moves up, the soil covers the seeds, and the partition is reset to its initial state to block the seeds. This reciprocating process can achieve interval sowing and ensure that the depth of the seeds in the soil is relatively uniform. The secondary depth can be adjusted by replacing the model of the C-frame and the eccentric wheel and adjusting the turning depth of the soil-turning part. The sowing depth can be adjusted manually, and the depth is relatively accurate. It can be used for trial planting in experimental fields, and can also be used as an ordinary seeder. It can ensure that the seeds are located at a more appropriate depth in the soil, and can also ensure that the growth of the seeds is relatively balanced.

[0022] An opening and closing structure is provided at the lower end of the vertical tube. When the vertical tube moves downward and extends into the soil, it remains closed to prevent soil from entering the vertical tube. When the vertical tube moves upward, the opening and closing structure automatically opens to ensure that the seeds can fall deep into the soil. The opening and closing structure includes closing plates 11 symmetrically arranged on both sides of the lower end of the vertical tube. The middle part of the closing plate is rotatably connected to the lower end of the vertical tube by a pivot. The upper end of the closing plate is hinged to the lower end of the arc plate 12. A torsion spring is installed on the hinge shaft. The upper end of the arc plate 12 is attached to the side of the vertical tube. Under the action of the torsion spring, the lower end of the arc plate 12 always gives an outward force to the upper end of the corresponding closing plate. This force can ensure that the lower ends of the two closing plates are attached together without being affected by other external forces, thereby ensuring that the opening and closing structure is in a closed state. When the vertical tube moves downward, the two closing plates attached together can remain attached together to prevent soil from entering. When the vertical tube moves upward, the lower end of the closing plate is not subject to the pressure of the soil, such as Figure 4 As shown, the arc-shaped plate is subjected to the inward pressure of the soil. When the pressure is greater than the force of the torsion spring, the upper end of the closing plate can be pushed inward. At this time, the lower ends of the two closing plates are separated, and the seeds can fall smoothly.

[0023] A notch is provided at the lower end of the vertical pipe corresponding to the closed position, and the closing plate is connected inside the notch by pivot rotation.

[0024] An air supply part is arranged in the vertical pipe, and the upper end of the air supply part is connected to a constant pressure component, which provides air pressure to the air supply part. The end of the air supply part is an air outlet valve 13. When the vertical pipe is located at the lower limit position, the air outlet valve opens, and the air supply part blows air toward the lower end of the vertical pipe, which can blow off part of the soil that has entered the vertical pipe, and can also blow open the closing plate, so that the seeds can be quickly blown out from the lower end of the vertical pipe into the soil, thereby improving the operating speed of the device.

[0025] The outlet valve is connected to an automatic trigger structure. When the vertical pipe reaches the lower limit position, the automatic trigger structure opens the outlet valve. The automatic trigger structure is preferably purely mechanical, which does not require electric control, reduces the complexity of the structure, and improves the stability of operation.

[0026] The automatic triggering structure includes an extrusion rod 14 which is laterally slidably arranged on the side wall of the vertical tube, and an arc-shaped extrusion block 15 is arranged on the side of the vertical rail. The extrusion rod 14 is connected to the side wall of the vertical tube by a spring, and the inner end of the extrusion rod 14 is connected to the button of the air outlet valve. When the outer end of the extrusion rod touches the extrusion block, the extrusion rod is forced to move toward the inside of the horizontal tube and squeeze the button of the air outlet valve at the same time. At this time, the air outlet valve opens; when the extrusion rod is separated from the extrusion block, it automatically resets, the button resets at the same time, and the air outlet valve automatically closes. When the vertical tube is at the lower limit position, the height of the extrusion rod 14 is flush with the height of the extrusion block.

[0027] The inner end of the extrusion rod is connected to the button through a clamping structure, and the extrusion rod drives the button to move actively. This design can ensure that the button of the exhaust valve will not get stuck after long-term use.

[0028] The above-described embodiments of the present invention do not constitute a limitation on the protection scope of the present invention. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
