Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and specifically to a garlic upright planter. Background Art

[0002] To meet the agronomic requirements of single-seed tip-up upright planting, it can not only achieve high yield, obtain garlic bulbs with large diameter and plump cloves, but also have fast and uniform emergence, which is convenient for field management. Since the natural stable state of garlic seeds is a lying state, and they are large in size, irregular and non-uniform in shape, it is difficult to achieve upright planting. Especially when the planting movement of the planter adopts continuous circular motion, although the garlic seeds can be planted under the continuous movement of the machine, the machine runs smoothly and the operation speed is high, but during the process of the planter inserting the garlic seeds into the soil, the horizontal component speed and acceleration are constantly changing, making it difficult for the garlic seeds to maintain their original upright state and be inserted into the soil. Currently, whether it is a garlic planter or the planter of a seedling transplanter with similar functional requirements, the symmetrical opening or unilateral opening of its symmetrical structure cannot offset the influence of the continuously changing horizontal component speed in the front-back direction on the upright state of the garlic seeds during upright planting, so that the garlic seeds can be planted in the soil in an upright state. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a garlic upright planter, which can achieve upright planting of single-seed oriented garlic seeds in the soil, is applicable to a continuous garlic upright planter, and has high operation efficiency and high uprightness of the planted garlic seeds.

[0004] To solve the above technical problems, the present invention provides the following technical solutions.

[0005] A garlic upright planter, comprising a planter body, an opening half shaft, a fixing plate, a support plate, a torsion spring, a crank arm, a roller shaft and a roller. The planter body consists of a front side of the planter and a rear side of the planter. The planter body is a hollow body with a wall thickness of 1.5 - 2.5 mm, composed of two upper and lower shapes. The upper shape is an inverted oblique frustum, inclined 1.5° - 3.5° to the right as a whole, with a frustum cone angle of 20°, and both the upper and lower bottom surfaces are horizontally arranged. The upper bottom surface opening is the garlic seed inlet, and its outer diameter size is such that the garlic seeds can smoothly fall into the planter body and the height of the planter body enables the planting depth of the planter to meet the garlic planting depth. The lower shape is an inverted oblique cone with a cone angle of 35° - 45° and a height of 28 - 32 mm. The left taper is the same as the left taper of the upper section, and the bottom outer diameter is the same as the lower bottom outer diameter of the upper section. The planter body is divided into the front side of the planter on the right and the rear side of the planter on the left by two intersecting planes passing through the central axis of the upper oblique frustum and the axis of the lower inverted cone and perpendicular to the vertical plane in the left - right direction. The upper bottom semi - toroidal surface of the upper section of the front side of the planter extends vertically upward with equal diameter and equal wall thickness. The two sides of the vertically extended part of the upper bottom surface of the upper section of the front side of the planter extend symmetrically with equal wall thickness to the left, that is, to the rear side of the planter, parallel to the vertical plane in the left - right direction. The opening half shafts, support plates, torsion springs and crank arms are all symmetrically arranged in two. Two opening half shafts are symmetrically welded to the outside of both sides of the extended part of the front side of the planter. The axes of the two opening half shafts are collinear and perpendicular to the vertical plane in the left - right direction, located on the left side of the center of the upper bottom surface of the upper section of the planter body and higher than the upper bottom surface of the upper section of the planter body. The fixing plate is welded to the rear side of the planter. The fixing plate is on the left side of the rear side of the planter and flush with the upper bottom surface of the upper section of the rear side of the planter. One support plate is symmetrically fixedly connected to each side of the fixing plate in the vertical direction. The two support plates are parallel to the vertical plane in the left - right direction, located outside the extended part of the front side of the planter respectively and each is provided with a through - hole that is in clearance fit with the two opening half shafts respectively. The two opening half shafts pass through the through - holes of the corresponding support plates respectively. A torsion spring is sleeved on each of the two opening half shafts outside the support plates. One end of a crank arm is fixedly connected to one end of each of the two opening half shafts outside the torsion springs. The other ends of the two crank arms are respectively bolt - connected to both ends of the roller shaft. A roller is arranged in the middle of the roller shaft. The two ends of the torsion spring are respectively pre - tightened and fixed on the corresponding support plate and crank arm.

[0006] The working process of the present invention is as follows: The garlic upright planting planter is installed on the continuous planting device of the garlic planter through its fixing plate or support plate, with the front side of the planter facing forward and the rear side facing backward. The front side and the rear side of the planter are in a closed state with tight contact on two intersecting sectional planes of the planter body due to the pre-tightening force of two torsion springs. During operation, the garlic upright planting planter makes a circular motion in the vertical plane of the forward direction while moving forward with the machine on the circular motion mechanism of the continuous planting device of the garlic planter. The direction of the circular motion is the same as the rotation direction of the walking wheels of the machine. During the movement, the orientation of the garlic upright planting planter remains unchanged, that is, the opening of the planter body always remains upward. When the garlic upright planting planter moves to near the highest point, single garlic seeds with the tip upward discharged by the seed metering device and the orientation mechanism of the garlic planter fall into the planter body. The garlic upright planting planter carries the garlic seeds and enters the soil before moving to the lowest position. When the planter enters the soil to reach the required depth at the lowest point, the opening mechanism on the garlic planter makes the roller of the garlic upright planting planter move downward, driving the front side of the planter to rotate counterclockwise around the axis of the opening half shaft against the pre-tightening force of the two torsion springs through the crank arm and the opening half shaft, opening the planter. The garlic seeds leave the planter by their own weight and fall into the soil. The garlic upright planting planter continues to move away from the soil, planting the garlic seeds in the soil with the tip upward in an upright state. After the garlic upright planting planter leaves the soil and continues to move, when the opening mechanism on the garlic planter completes the action on the roller, the front side of the planter returns to its original position under the action of the two torsion springs to close the planter, completing one working cycle.

[0007] The beneficial effects achieved by the present invention are as follows.

[0008] 1. Through the shape of the upper section of the planter body of the garlic upright planting planter, the present invention enables the garlic seeds falling into the planter body to maintain a high uprightness before moving to the planting position and being opened.

[0009] 2. Through the outer shape of the planter body of the garlic upright planting planter, especially the outer shape of the lower section, the present invention enables the garlic seeds to maintain an upright state and fall into the seed hole under the repeated alternating action of the front side and the rear side of the planter during the process of leaving the planter for planting. At the same time, the shape of the seed hole formed by the action of the planter entering the soil on the soil has a high degree of symmetry and a taper with a lower middle and higher periphery at the bottom of the hole. The action of the soil backflow on the garlic seeds is nearly the same in all directions, which is beneficial for the garlic seeds to stand upright in the soil.

[0010] 3. The present invention is applicable to garlic planters with continuous planting motion of the planter. It can make the garlic planter operate smoothly and efficiently, while overcoming the influence of the continuously changing horizontal component speed of the planter during the process of planting garlic seeds on the upright state of the garlic seeds, and the planted garlic seeds have a high uprightness.
