Description

Improved electric portable tea plucking machine

Technical Field

The utility model relates to agricultural machinery especially relates to a modified electronic portable tea-leaf picker.

Background

The tea plucker is a crop harvesting machine for plucking fresh tea leaves from the top tips of tea trees. The structure of a common electric portable tea-leaf picker in the market is shown in a utility model patent of Chinese patent No. 2018210399596, and comprises a machine body, wherein a tea-collecting frame is arranged on one side of the machine body, the bottom in the tea-collecting frame is downwards sunken to form a sunken surface, and a plurality of water through holes are formed in the sunken surface; the outer bottom indent of collection tea frame shaping has the joint face, and joint face below is equipped with cutter mechanism, has seted up two at least mounting holes on the joint face in proper order, cutter mechanism includes the last blade and the bottom knife of rectangular shape, installs the eccentric wheel actuating mechanism of blade reciprocating motion about the drive in the organism. When in operation, the user only needs to hold the handle to start the power switch and aim the blade group at the tea to cut in a reciprocating way, thus realizing the tea picking operation. The electric portable tea plucker can reach the working benefits of 3-5 labors at least in one day by one single machine for mountain climbing operation, and the quality of the plucked tea can reach the same level as that of manual plucking, so that the electric portable tea plucker is suitable for original ecological tea plucking operation and light pruning of tea trees. However, when the upper blade and the lower blade of the blade group of the conventional electric portable tea plucking machine slide relatively at a high speed, the tooth tips of the cutter teeth are easy to wear, and gaps are easy to appear on the cutting edges of the upper blade and the lower blade, so that branches and leaves are easy to break during cutting, and the output and the quality of next-stage tea leaves are influenced; in addition, the reciprocating cutting stroke of the blade at the outermost side is usually furthest to the outer frame of the leaf collecting frame, so that the range of the cut tea leaves is smaller than the length of the leaf collecting frame in the using process, the leaf collecting frame cannot be fully utilized, and the tea picking efficiency is influenced.

Disclosure of Invention

An object of the utility model is to provide a modified electronic portable tea-leaf picker.

Realize the utility model discloses the technical scheme of purpose is: an improved electric portable tea plucker comprises a leaf collecting frame, a blade group and a machine body, wherein the leaf collecting frame is formed by enclosing a bottom plate, two side plates and a back plate, the top of the leaf collecting frame and the front part opposite to the back plate are open, the machine body is fixedly installed beside any side plate, the blade group comprises an upper blade and a lower blade, a plurality of cutter teeth are arranged on the blade bodies of the upper blade and the lower blade at equal intervals, the bottom surface profile of each cutter tooth is in a trapezoid shape with a narrow tooth tip and a wide tooth root, the upper surface of each cutter tooth forms a blade part at the tooth tip and on two sides of the tooth tip respectively, the cutter teeth of the upper blade and the lower blade form a plurality of pairs of cutting pairs in a one-to-one correspondence manner, a strip-shaped cutter frame is fixedly installed at the bottom of the front end of the bottom plate of the leaf collecting frame, and the upper blade and the lower; a power transmission mechanism for driving the upper blade and the lower blade to reciprocate is arranged in the machine body, and the upper blade and the lower blade are respectively in transmission connection with the power transmission mechanism; when the upper and lower cutter teeth of each pair of cutting pairs are aligned, the tooth tips of the upper and lower cutter teeth are attached, and a gap of 0.15-0.25 mm is formed between the tooth roots of the upper and lower cutter teeth.

Furthermore, the maximum stroke of the cutter teeth of the blades above the effective cutting length of the upper blade and the lower blade and the outermost side of the lower blade departing from the machine body can reach the inner side wall of the side plate above the position, and the maximum stroke of the cutter teeth of the blades above the outermost side of the machine body close to the upper blade and the lower blade can reach the inner side wall of the side plate above the position. The cutting efficiency is improved.

Furthermore, a plurality of water holes are uniformly arranged on the bottom plate of the leaf collecting frame at intervals.

Generally, in order to ensure that the blade is cut to be sharp, the upper cutter tooth and the lower cutter tooth are attached to each other as much as possible only by means of empirical values, and the applicant researches and finds that the tooth root of each cutter tooth is too attached to easily cause the tooth warping phenomenon, so that the problem can be solved by adjusting the gap between the tooth roots; however, if the clearance between the tooth roots is too large, the cutting edges are engaged again, and the cutting teeth are partially broken. The utility model discloses a inject the bottom surface profile and be trapezoidal, keep 0.15 ~ 0.25 mm's clearance between the tooth root section of upper and lower sword tooth, can guarantee that the blade during operation cuts keenly to make upper and lower sword tooth contact surface have good autogenous grinding function at the shearing in-process, the prong is difficult for wearing and tearing more, has promoted the life of blade, and is favorable to becoming more meticulous, the standardized operation of blade processing.
