Problems solved by technology

Combining the functions of the pick-up teeth in different positions, the drum guard is designed as a combined structure of multi-section arcs and straight lines to improve the utilization rate of the pick-up teeth in the pick-up position, and the "back" installation method of spring teeth and involute opening are designed. The guard plate structure of the wire drum solves the problem of pinning the peanut plants by the arc-shaped curved teeth and the guard plate of the push station

Embodiment 1

[0055] Example 1: as Figure 1-Figure 9 As shown in the figure, a helical gear roller type peanut pickup device of the present invention includes a pickup tooth 1, a drum guard 7, a pickup drum, a left side plate 2, a right side plate 8, and a rear side plate 5, and the center shaft 3 of the pickup drum is installed On the bearings of the left side plate 2 and the right side plate 8, the left side plate 2 and the right side plate 8 are fixedly connected with the rear side plate 5; the roller guard 7 is interposed between the adjacent toothed roller seats 6 of the pick-up roller and installed at the rear On the side plate 5, the pick-up drum rotates with the central shaft 3, and cooperates with the unit to move the pick-up tooth 1 forward to pick up the peanut plants from bottom to top, and complete a working cycle of picking, lifting, pushing, and emptying in turn.

[0056] like figure 1 , Image 6 , Figure 7 As shown, the pick-up drum includes a central shaft 3 and a plur...

Embodiment 2

[0068] Example 2: as Figure 1-Figure 9 As shown, the difference between this example and Example 1 is: the toothed roller disc in this example is evenly provided with 5 picking teeth 1 along its circumferential direction, and the circumferential offset angle α between the picking teeth of adjacent toothed roller discs 2 =24°, arranged in the same direction of rotation. The arrangement of the picking teeth 1 in this example is a left-handed arrangement; Figure 10 As shown in the figure, the thickness is 2-5mm, the working surface is concave arc, and the tooth root is hinged with the toothed roller seat by an elastic structure, that is, the tooth root of the pick-up tooth 1 is connected to the toothed roller seat by a torsion spring, and it oscillates repeatedly within 10-20° , to avoid damage when encountering obstacles during pickup. This example is made of wear-resistant composite material, which can increase the frictional force and centripetal force of the pick-up tooth...

Embodiment 3

[0075] Example 3: The difference between this example and Example 1 is: as Figure 1-Figure 9 As shown in the figure, the toothed roller disc in this example is evenly provided with 8 pickup teeth 1 along its circumferential direction, and the circumferential offset angle α between the pickup teeth of the adjacent toothed roller discs 2 =15°, arranged in the same direction of rotation. The arrangement of the picking teeth 1 in this example is a right-handed arrangement. The arc radius R of the pick-up tooth 1 4 =163.1mm. Pick-up tooth length L 1 is 128.9mm, the mounting angle β of the pick-up tooth 1 5 = 28.7°.

[0076] The phase angles of the pick-up drum corresponding to the pick-up, lift, push and idling positions along the circumference are β respectively. 1 ~β 4 , in this case β 1 =79.8°, β 2 =90°, β 3 =79.1°, β 4 =111.1°.

[0077] (1) The curve section of the pick-up station consists of an arc constitute; of which, for the same section O 1 is the center ...

Abstract

The invention discloses a spiral tooth roller type peanut picking device, and belongs to the technical field of agricultural machinery. Comprising picking teeth, a roller protection plate, a spiral picking roller, a left side plate, a right side plate and a rear side plate, a center shaft of the picking roller is installed on bearings of the left side plate and the right side plate, and the left side plate and the right side plate are fixedly connected with the rear side plate. Four to eight pick-up teeth are evenly arranged on the tooth roller discs in the circumferential direction of the tooth roller discs, the pick-up teeth are fixed on the tooth roller seat, the tooth roller discs are installed on the center shaft at equal intervals in the axial direction of the center shaft, and the pick-up teeth of the adjacent tooth roller discs are arranged in the same rotating direction in the circumferential direction in a staggered mode by 15 degrees to 30 degrees. During picking operation, the picking teeth are in contact with peanut plants in sequence, and the phenomenon of'heap 'can be effectively avoided. And the protective plates are arranged between the adjacent tooth roller seats and are mounted on the rear side plate. The roller rotates along with the center shaft and is matched with the unit to move forwards, the elastic teeth pick up peanut plants from bottom to top, and a working cycle of picking, lifting, pushing and backlash is completed in sequence.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a helical gear roller type peanut picking device. Background technique [0002] my country has a wide range of peanut planting areas, among which Henan, Shandong, Hebei, Guangdong, Sichuan and Liaoning have larger planting areas, with a total output of 1.7×10 7 t ranks first in the world. In 2012, the peanut planting area in my country was 4.63×106hm 2 , and the machine harvesting level is only 26.04%, which seriously restricts the healthy development of my country's peanut industry as a whole. [0003] At present, small peanut picking and harvesting machines have been developed that are equipped with three types of peanut picking devices: spring-toothed drum type, telescopic finger-pick-up type and toothed belt type. Auxiliary pick-up devices such as reels, grass press rollers, etc. However, these machines have problems of high omission rate and high fruit dro...
