Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to a leaf vegetable reed roller. Background Art

[0002] In my country, with the development of modern agriculture, the level of mechanization in agricultural production is getting higher and higher. Agricultural production such as corn, soybeans, and rice has basically achieved full mechanization, but there is still a big gap from full mechanization. One of the shortcomings is the low level of mechanization in vegetable production, especially vegetable harvesting. Vegetable harvesting is the most time-consuming and labor-intensive link for vegetable farmers, resulting in high vegetable production costs, weak market competitiveness, low income for vegetable farmers, and poor enthusiasm for growing vegetables. There are many types of vegetables, and different varieties have different edible parts, so there are huge differences in their harvesting methods. The same variety has different harvesting periods and different harvesting methods. For green leafy vegetables such as spinach, lettuce, rapeseed and other varieties, whether they are short leafy vegetables or taller leafy vegetables, they all have the characteristics of fresh and weak leaves, thin and crisp veins, uneven heights, and many harvesting methods. It is manual harvesting, with high labor intensity, low work efficiency, getting up early and catching up late, without good economic benefits, and ultimately dare not plant on a large scale; currently, a small number of leafy vegetable harvesting adopts semi-mechanized operations, which are suitable for harvesting leafy vegetables in small areas such as greenhouses and sheds. The operation quality is poor, the versatility is weak, and the harvesting efficiency is low. For large-scale vegetable planting, its harvesting operation still has huge problems; the leafy vegetable reed roller is a key component of the leafy vegetable harvester, which determines the damage rate of the harvested leafy vegetables, the operation efficiency and the uniformity of the harvested leafy vegetables. Some of the current leafy vegetable harvesters are not equipped with reed rollers, and the equipped reed rollers cannot play their due role, so the research on the leafy vegetable harvesting reed roller is very necessary. The design of the reed roller improves the operating speed and operation quality of the leafy vegetable harvester, and has high applicability and popularization. Summary of the invention

[0003] The purpose of the present invention is to provide a leaf vegetable pulling roller, which effectively assists the cutting knife to complete the cutting operation, ensures the neatness of the leaf vegetables after cutting, and at the same time quickly and orderly pulls the leaf vegetables onto the conveyor belt, thereby improving the harvesting efficiency, causing little damage to the leaf vegetables, having strong applicability, simple assembly, diverse combinations, easy maintenance, low cost, and easy promotion.

[0004] To achieve the above-mentioned purpose, the technical solution of the present invention is: a leafy vegetable plowing roller includes a plowing shaft, a locking nut, a long finger plate, a short finger plate, a spacer, and a baffle. The plowing shaft alternately passes through the long finger plate, the spacer, and the short finger plate, baffles are installed on both sides, and the outermost end is fixed with a locking nut.

[0005] There are two long keyways on the reel shaft, and the angle between the center of the keyway and the axis is 45 degrees.

[0006] The long finger plate includes a long finger, a short finger and a finger seat, all of which are made of TPE or PVC, with a thickness H of 10-14mm, a diameter D1 of the finger seat of 135mm, a shaft hole with the same outer diameter as the reel shaft is provided in the center, and a convex key with the same depth and width as the keyway of the reel shaft is provided on the shaft hole; 12 long and short finger embedding grooves are arranged along the center of the shaft hole on the ring surface of the finger seat, including 6 long finger embedding grooves and 6 short finger embedding grooves, the arc center of the long finger embedding groove is 30mm from the center of the shaft hole, the arc radius r1 is 10mm, the embedding groove width h2 is 16mm, the two sides are consistent with the arc center line, and the arc center of the short finger embedding groove is 10mm from the center of the shaft hole. The center L is 45mm, the arc radius r2 is 10mm, the embedded groove width h3 is 16mm, and the distances between the two sides of the arc center line are consistent; the finger has a long finger and a short finger. One end of the long finger and the short finger inserted into the embedded groove is the installation end, and the other end is the working end. The arc radius, finger width, finger length of the installation end of the long finger and the short finger are the same as the size of the embedded groove. The working end is divided into a straight working section and an arc working section. The distance between the upper and lower end points of the straight working section is 28mm, the width of the straight working section is the same as the width of the embedded groove, the arc diameter D2 of the end of the arc working section is 15mm, and it is consistent with the center line of the arc of the installation end. The distance between the two arc ends of the long finger is 143mm, and the distance between the two arc ends of the short finger is 143mm. The distance between the two arc ends is 128mm. The left reference line of the inner arc of the arc working section is 5mm to the left of the center line of the straight working section, the right reference line of the inner arc of the arc working section is 5mm to the right, and the outer arc reference line of the arc working section is 15mm to the left. The lower end point on the left side of the straight working section is the upper reference point of the outer arc. The lower end line of the straight working section is translated downward by 5mm and the intersection with the right reference line of the inner arc is the upper reference point of the inner arc. The upper reference point of the outer arc is tangent to the outer arc reference line and then tangent to the arc at the end of the arc working section. The arc transitions with the left line of the straight working section with an arc with a radius of 10mm to form the outer edge of the arc working section. The upper reference point of the inner arc is tangent to the outer arc reference line and then tangent to the arc at the end of the arc working section. The point is tangent to the left reference line of the inner arc and then inscribed with the arc at the end of the arc-shaped working section to form an arc. The arc transitions to the right line of the straight working section with an arc with a radius of 10mm to form the inner edge line of the arc-shaped working section. The arc-shaped working section is formed, and the working end is formed with the straight working section, and the long and short fingers are formed with the installation end. When working, the arc-shaped working section can increase the contact area with the leafy vegetables and reduce the damage to the leafy vegetables; shortening the length of the straight working section to 8mm can obtain another set of 123mm long fingers and 108mm short fingers, which can be installed on the finger seat to obtain a short finger plate; the two sets of fingers can be installed alternately and symmetrically on the finger seat, or the number of installed finger fingers can be reduced accordingly, which will generate a variety of finger plates.

[0007] The diameter of the spacer is 135 mm, and a shaft hole and a convex key with the same size as the shaft hole of the finger seat are arranged in the center. The material and thickness of the spacer are the same as those of the finger seat.

[0008] The baffle is made of an iron plate with a diameter of 135 mm and a thickness of 3 mm, and a center hole and a convex key that match the reel shaft are provided at the center.

[0009] The invention is made of TPE or PVC material, which is safe, environmentally friendly, and has good softness, can reduce damage to leafy vegetables to the greatest extent, and improve work efficiency.

[0010] The assembly method of the finger plates and spacers installed on the reed shaft of the present invention can be adjusted according to the situation of leafy vegetables, such as installing all the same finger plates, stacking two or more of the same finger plates together and then installing spacers, stacking spacers, and alternately installing the convex keys of the finger plates in two key slots.

[0011] The embedded installation of the finger of the present invention reduces the replacement cost of damaged fingers and improves the replacement efficiency. A variety of finger assembly methods and a variety of finger plate assembly methods are used. The finger strengths are different and different straw-pushing forces are generated, ensuring that one straw-pushing roller can meet the harvesting and straw-pushing functions of different leafy vegetables, thereby improving the harvesting quality and work efficiency of leafy vegetables.
