Problems solved by technology

Existing blueberry harvesting machines are mainly vibrating harvesting machines. Harvesting machines impose forced vibration on blueberry plants. It is difficult to control the vibration parameters during the harvesting process. If the control is not done properly, it will cause great mechanical damage to blueberry trees and fruits, resulting in fruit damage. The quality and its economic value have declined, therefore, there is an urgent need to invent a new type of harvesting machine for harvesting blueberries by combing

[0023]Rotary brush blueberry harvester, its main components include suspension frame 26, outer frame 13, inner frame 11, tree height follower adjuster, crown diameter follower adjuster, tree crown guide, hydraulic motor 6, T-shaped groove slideway 27, T-shaped sliding seat 28, reduction box 12, reduction box base 14, rotating brush mandrel support frame 15, rotating brush assembly, fruit conveying device, front traveling wheel 24, rear traveling wheel 19, collection box take-up plate 21, Collection box baffle plate 22, fruit collection box 23, according to the above-mentioned rotary brush type blueberry harvester, the described tree height following adjuster includes height adjustment guide cylinder 5, height adjustment lifting rod 9, height adjustment handwheel 1, screw shaft Hole worm wheel support 2, axial thrust bearing 3, screw shaft hole worm wheel 41, worm shaft 40 at both ends, lifting screw shaft 4, according to the above-mentioned rotary brush blueberry harvester, the...

Embodiment 2

[0026] The tree height following adjuster mainly includes height adjustment guide cylinder 5, height adjustment lifting rod 9, height adjustment hand wheel 1, screw shaft hole worm wheel support 2, axial thrust bearing 3, screw shaft hole worm wheel 41, two ends The worm shaft 40, the lifting screw shaft 4, the height-adjusting guide tube 5 are fixed on the outer frame 13, the height-adjusting lifting rod 9 is fixed on the top of the inner frame 11, and the height-adjusting lifting rod 9 is drilled with a height adjustment hole. The guide cylinder 5 and the height-adjusting lifting rod 9 are fixed by bolts, the screw shaft hole worm wheel support 2 is fixed on the top of the outer frame 13, and the lifting screw shaft 4 passes through the screw shaft hole. The worm wheel support 2 is matched with the inner frame 11 through a sleeve. The center of the spiral shaft hole worm gear 41 is an internal thread hole structure, which is assembled with the lifting screw shaft 4 to form a ...

Embodiment 3

[0028] The crown diameter following adjuster includes a supporting plate 29, a large bevel gear 34, a small bevel gear 35, a crown diameter adjusting screw 7, and a spiral slide seat 10. The supporting plate 29 is fixed in the center of the top of the inner frame 11 At the position, the large bevel gear 34 is fitted on the supporting plate 29 and meshes with the four small bevel gears 35. The axes of the four small bevel gears 35 are spaced 90° apart from each other in the same plane. One end of the shaft device and the crown diameter adjusting screw 7 is fixed, and the other end of the crown diameter adjusting screw 7 is a square joint, and 4 crown diameter adjusting screw 7 are assembled on the inner frame 11 through the bearing seat, for different For blueberry plants with a crown diameter, any crown diameter adjustment lead screw 7 can be rotated, and the other three crown diameter adjustment lead screws 7 are driven to rotate through the meshing of the large bevel gear 34 ...

Abstract

A rotating brush type blueberry harvester mainly comprises an outer framework, an inner framework, a tree height follow-up regulator, a crown diameter follow-up regulator, a hydraulic motor, a rotating brush assembly, a crown guider, a fruit conveyer, and a fruit collector box; in usage, blueberry plants enter the center of the rotating brush assembly through the crown guider; the hydraulic motor drives a rotating brush mandrel to rotate; elastic brush teeth on the rotating brush mandrel brush the blueberry plants, so the mature blueberry fruit can fall on a conveyer belt of the fruit conveyer, and sent to the fruit connector box, thus realizing fruit contentious and automatic harvesting; the harvester uses the brush mode to contentiously harvest the blueberry, is high in harvesting efficiency, and small in mechanical damage on the fruits; the work parameters of the tree height follow-up regulator and the crown diameter follow-up regulator can be adjusted, so the harvester can suit for blueberry plants of different heights and crown diameters of various kinds; the harvest can also harvest other small berries, and is wide in application scope.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to a machine for harvesting blueberries with a rotating brush. Background technique [0002] In recent years, my country has successfully carried out industrialized production and cultivation of blueberries, and the varieties and yields have increased year by year. The demand for mechanized blueberry harvesting is increasing day by day. Existing blueberry harvesting machines are mainly vibrating harvesting machines. Harvesting machines impose forced vibration on blueberry plants. It is difficult to control the vibration parameters during the harvesting process. If the control is not done properly, it will cause great mechanical damage to blueberry fruit trees and fruits and lead to fruit damage. Quality and its economic value decline, therefore, need badly to invent a kind of novel harvesting machinery of harvesting blueberry with comb mode. Contents of the invention [0003...
