Description

A four-bar picking head for camellia oleifera fruit picking machine

technical field

The utility model relates to a four-bar picking head used for a camellia oleifera fruit picking machine.

Background technique

Camellia oleifera oil has been chosen and loved by more and more families. It has high nutrition and good taste. The planting area and scale of camellia oleifera in my country are also increasing, which brings about the problem of picking camellia oleifera fruit. For a long time, the mechanization of camellia oleifera fruit picking is not high, and it is basically done manually. The labor intensity is high, a lot of manpower and material resources are wasted, and the efficiency is very low. So far there is no complete device on the market to solve this problem.

Because Camellia oleifera flowers and fruits are in the same period, some of them are used for picking machinery of Camellia oleifera fruits. During the picking process, Camellia oleifera flowers are likely to fall off, which affects the output of Camellia oleifera fruits in the later stage.

Through the research on the Camellia oleifera trees in the large-scale Camellia oleifera planting bases, it is found that the Camellia oleifera trees have relatively strong branch toughness, basically no fruit on the trunk of the Camellia oleifera tree, and the fruits are mainly distributed at the front ends of the branches of the Camellia oleifera tree.

Utility model content

Aiming at the low degree of mechanization, labor intensity and low picking efficiency in the current picking of camellia oleifera, the utility model provides a four-bar picking head for a camellia oleifera fruit picking machine, which can realize the automation and continuity of picking actions , and the inter-agency coordination is good and practical.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a four-bar picking head for camellia oleifera fruit picking machine, which includes two sets of crank rockers arranged in parallel and composed of cranks, connecting rods, rockers and support frames. Rod mechanism, the front ends of the connecting rods of the two groups of crank rocker mechanisms are connected together by a crossbeam, and a plurality of working teeth are arranged side by side on the front end of the crossbeam; the rear ends of the connecting rods are hinged on the rocker, and the other end of the rocker is hinged On the support frame, a crank is hinged in the middle section of the connecting rod, and the other end of the crank is connected with the power shaft.

The connecting rod is V-shaped as a whole, and the V-shaped top part of the connecting rod is hinged with the crank.

The front ends of the working teeth are arc-shaped, which is convenient for "combing" to take the camellia oleifera fruit.

The utility model skillfully utilizes the movement track of each mass point of the crank rocker mechanism, and through the continuous circumferential rotation of the crank around the power shaft, the connecting rod and the rocker are driven to swing regularly, so that the movement of the working teeth can successfully turn the Camellia oleifera The fruit is "combed" from the branches. Experiments have proved that this scheme can successfully "comb" the fruit, and the Camellia oleifera will not fall off.

Compared with the prior art, the beneficial effects of the utility model are: the coordination between the various components of the utility model is good, the installation and maintenance are convenient, the continuity of the picking action can be ensured, and the automation of the mechanism can be realized. and promotion to provide strong technical support.

Detailed ways

A four-bar picking head for Camellia oleifera fruit picking machine, as shown in Figures 1 and 2, includes two sets of crank and rocker mechanisms arranged in parallel and composed of crank 1, connecting rod 3, rocking bar 4 and support frame 5, The front ends of the connecting rods 3 of the two groups of crank-rocker mechanisms are connected together by a crossbeam 7, and 10 working teeth 2 are arranged side by side on the front end of the crossbeam 7, and the tail ends of each working tooth 2 are fixed on the crossbeam 7 by welding or screwing , the front ends of each working tooth 2 are in an arc shape that is convenient for "combing" to get the camellia oleifera fruit. The rear end of the connecting rod 3 is hinged on the rocker 4 through the pin 6, and the other end of the rocking rod 4 is hinged on the support frame 5 through the pin 6. The connecting rod 3 is V-shaped as a whole, and the V of the connecting rod 3 The shape top part is hinged with crank 1 by bearing pin 6, and the other end of crank 1 links to each other with power shaft.

The utility model skillfully utilizes the movement track of each mass point of the crank rocker mechanism, and through the continuous circumferential rotation of the crank around the power shaft, the connecting rod and the rocker are driven to swing regularly, so that the movement of the working teeth can successfully turn the Camellia oleifera The fruit is "combed" from the branches. Experiments have proved that this scheme can successfully "comb" the fruit, and the Camellia oleifera will not fall off.
