Abstract

The invention relates to a differential-type blueberry picking mechanism. In view of the feature that the binding force between mature blueberry fruits and branches is small, actuating components at the tail ends of picking devices are designed into elongated round rods, and in order to avoid the damage of the blueberry fruits during picking, rubber is sleeved outside the elongated round rods. During working, a diesel engine rotates to drive a worm gear speed reducer to rotate, and the worm gear speed reducer drives a hinged four-link mechanism formed through an eccentric wheel, so as to drive an actuating mechanism at the tail end of one of the picking devices to swing back and forth; an actuating mechanism at the tail end of the other picking device on the other side is driven to swing together through a differential lever, the swing angles of the actuating mechanisms at the tail ends of the picking devices on two sides have difference in certain numerical value; and when the picking devices pass through blueberry trees, swing devices on the two sides can swing and shake blueberry branches from side to side to shake off the fruits, so as to realize the picking of blueberries.

Description

Differential type blueberry picking fruit mechanism

Affiliated technical field

Mechanism involved in the present invention is a kind of device that can carry out the mechanization harvesting to the blueberry fruit, this device adopts the mode of rocking that rocks back and forth to act on the blueberry branch, rock the blueberry fruit that shakes above the branch, the blueberry that is fallen by shake is dropped in the following fruit gathering unit, realize the mechanization of blueberry is plucked.

Background technology

In recent years, along with people's continually developing to health food, blueberry is because of the nutritious approval that more and more obtains people, market demand and year sharp increase at China's blueberry, the blueberry cultivated area also enlarges year by year, but as in the blueberry plantation bottleneck problem---blueberry harvesting technology never obtains fine solution.In China, whenever the blueberry mature period, all can drop into great amount of manpower and remove to pluck blueberry, not only picking efficiency is low, but also has improved the production cost of blueberry, and the ratio that makes blueberry harvesting expense account for totle drilling cost is about 50%～70%.Given this, invent a kind of picker can realize plucking efficiently to ripe blueberry imperative.

Summary of the invention

According to the blueberry growth characteristic, design a kind of differential type blueberry picking fruit system, can carry out mechanization to the blueberry fruit and pluck.Technical scheme is as follows: utilize the short and small relatively characteristics of blueberry fruit tree, the terminal executing agency of picker is placed in the both sides of picking vehicle, Diesel Driven eccentric wheel during work, drive terminal executing agency with certain angle and amplitude swing by four-bar linkage, when picking vehicle process blueberry fruit tree, the terminal actuating unit that is placed in the picking vehicle both sides constantly waves branch and rocks.Because the blueberry fruit is structure in pelletized form, and the ripe blueberry fruit and the adhesion of branch are less, and the adhesion of immature blueberry fruit and branch is bigger, so the following blueberry fruit with maturation that constantly rocks of actuating unit shakes endways, thereby the mechanization that realizes the blueberry fruit is plucked.

Great advantage of the present invention is by the terminal executing agency of blueberry picker, realized the mechanization harvesting of blueberry, can improve the picking efficiency of blueberry, overcome low, the weak points such as labour intensity is big, production cost height of artificial harvesting blueberry efficient, promote development with the blueberry plant husbandry that promotes China.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is a differential type blueberry picking fruit mechanism fundamental diagram;

1. picking vehicle frameworks among the figure, 2. diesel engine, 3. worm type of reduction gearing, 4. driving-belt, 5. rotating shaft, 6. underframe, 7. eccentric wheel, 8. connecting rod 1, and 9. connecting rod 2,10. the left side picking mechanical arm, 11. differential lever, 12. connecting rods, 3,13. right side picking mechanical arms, 14. fruit gathering units.

Operation principle

As shown in Figure 1, (1) is the mechanical framework of picking vehicle, be used to install the designed differential type blueberry of this patent and pluck mechanism, blueberry is plucked mechanism and is made of parts 1～14, operation principle is as follows, prime mover (2) drives worm type of reduction gearing (3), change the direction of motion, reducer output shaft drives rotating shaft (5) by driving-belt (4) and rotates, rotating shaft is installed on the underframe (6), the four-bar linkage of being made up of eccentric wheel (7), connecting rod (8), connecting rod (9) is housed in the rotating shaft, drives left side blueberry picking mechanical arm (10) swing; Simultaneously, because differential lever (11) is connected with connecting rod (9), connecting rod (12), make the also swing together thereupon of picking mechanical arm (13) on right side, when picker is set through blueberry, it is differential that the both sides picking mechanical arm acts on the branch front and back, make blueberry fruit on the blueberry branch under the differential swing effect of both sides picking mechanical arm, shake and falls on the following fruit gathering unit (14), thereby realize the mechanization harvesting of blueberry.

Claims

1. differential type blueberry picking fruit mechanism, concrete feature is: diesel engine (2) drives worm type of reduction gearing (3), drive driving-belt (4) rotating shaft (5) is rotated, drive the four-bar linkage motion, realize the picking mechanical arm swing of both sides by differential lever (11).

2. differential type blueberry picking fruit according to claim 1 mechanism drive disk assembly---by the four-bar linkage that eccentric wheel (7), connecting rod (8), connecting rod (9) are formed, be installed in the inboard of picking vehicle interior of body.During work, under the drive of rotating shaft, drive picking mechanical arm and realize the swing action.

3. differential type blueberry picking fruit according to claim 1 mechanism drive disk assembly---be connected with connecting rod (9), connecting rod (12) by differential lever (11), make the both sides picking mechanical arm when swing, have certain phase difference, form the differential type wobbling action.
