Description

Portable Berry Harvester

Technical field

The utility model belongs to agricultural machinery, in particular to a berry harvesting machine.

Background technique

The nutritional value and economic value of berries are very high, but the current berry harvest in my country is mainly harvested by hand and manual harvester, which has low labor efficiency and high labor intensity. Domestic and foreign mechanical harvesting of berries mainly adopts two methods: mechanical vibration and air suction. Mechanical vibration can be divided into two types: pushing and shaking the main trunk and dry branches, and impacting the main branches and small branches. Foreign berry mechanical vibration harvesters are mostly large self-propelled harvesters, which are expensive and require high planting management in harvested fields, while portable small berry harvesters generally have poor harvesting effects and low harvesting efficiency. Fruit branches are more damaged and labor-intensive.

Contents of the invention

The purpose of this utility model is to provide a portable berry harvester aimed at the problems of the above-mentioned prior art, relying on an eccentric device to make the harvesting rod produce periodic motion, and the harvesting rod flexibly impacts the main branch and small branch of the berry, so that the fruit Break away from the branches to complete the fruit picking process. The portable berry harvester can be manually carried or hand-held for harvesting, or one or several portable berry harvesters can be installed on existing walking sites or tractors to complete the harvesting work.

The purpose of the utility model can be achieved through the following scheme: a portable berry harvester, comprising a power machine, a clutch and a gearbox assembly, a handle, a handle cover and a transmission shaft. The end of the transmission shaft is fixed with an eccentric crank, and the end of the eccentric crank is coaxially and rotatably equipped with a harvesting disc. The eccentric crank and the harvesting disc constitute an eccentric device. The harvesting rods are evenly distributed in turn, and the limit swivel is set on the handle in flexible contact, and an elastic strip is connected between the harvesting working part formed by the harvesting disc and the harvesting rod and the limit swivel.

The harvesting rod is made of elastic material, and the surface of the harvesting rod is covered with flexible material. A large eccentric block and a small eccentric block are fixedly mounted on the end of the transmission shaft in sequence, wherein the large eccentric block and the eccentric crank are on different sides, and the small eccentric block and the eccentric crank are on the same side. A protective cover is fixedly installed at the end of the handle, and the protective cover is fitted on the outside of the eccentric crank and the large eccentric block with clearance.

The beneficial effects of the utility model are: simple structure, high harvesting efficiency, low berry damage rate, low cost, small vibration, convenient and reliable use, and can harvest berries such as seabuckthorn, blackcurrant, blueberry, wolfberry, etc. Harvest walnuts, olives, hazelnuts, dates, apples, citrus and other crop fruits.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described. A portable berry harvester includes a power machine 1, a clutch and gearbox assembly 2, a handle 3, a handle cover 4 and a transmission shaft 5. The end portion of transmission shaft 5 is fixedly equipped with eccentric crank 9, and the end portion of eccentric crank 9 is coaxially and rotatably equipped with harvesting disc 10, and eccentric crank 9 and harvesting disc 10 constitute an eccentric device. On the circumferential direction of the disc 10, harvesting rods 11 are evenly distributed in turn, and the limited rotating sleeve 6 is set on the handle 3 in flexible contact. Elastic strips 13 are connected between the limiting rotary sleeves 6 .

The harvesting rod 11 is made of elastic material, and the surface of the harvesting rod 11 is covered with a flexible material. The end of transmission shaft 5 is fixed with large eccentric block 12 and small eccentric block 8 successively, wherein large eccentric block 12 and eccentric crank 9 are on the opposite side, small eccentric block 8 and eccentric crank 9 are on the same side. A protective cover 7 is fixedly installed at the end of the handle 3 , and the protective cover 7 is fitted on the outside of the eccentric crank 9 and the large eccentric block 12 with a gap.

When working, it can be powered by a power machine 1 such as an electric motor, a gasoline engine, an air motor, and a power input flexible shaft, and the transmission shaft 5 can obtain an appropriate speed and torque through the clutch and gearbox assembly 2, so that the eccentric shaft fixed at the end of the transmission shaft 5 The crank 9 rotates, and the rotation of the eccentric crank 9 causes the harvesting working parts composed of the harvesting disc 10 and the harvesting rod 11 to move, and at the same time, due to the movement restriction of the limiting rotary sleeve 6 and the elastic bar 13 to the harvesting working parts, the harvesting The movement of the disk 10 and the harvesting rod 11 is approximately parallel movement, and the trajectory of each point is a circle, and the instantaneous speed and acceleration of each point are the same. Under normal working conditions, due to the effect of friction, the limiter rotating sleeve 6 is fixed relative to the handle 3. The position turning sleeve 6 rotates relative to the handle 3, so that on the one hand, avoiding fruit branch damage, on the other hand, it is convenient for the harvester to move under the harvesting working state, so as to improve the harvesting efficiency. The harvester adopts the large eccentric block 12 and the small eccentric block 8 to balance the inertial force produced by the eccentric device and the partial inertial force produced by the fruit branch, so that the vibration of the harvester is small, the labor intensity is reduced, and its reliability is improved. When harvesting, the harvesting rod 11 flexibly bumps into the main branch and twigs of the fruit tree, causing the berries to accelerate. When the inertial force of the berries is greater than the resistance to breaking away, the fruit will break away from the branches and complete the fruit picking process. The portable berry harvester can be manually carried or hand-held for individual operation and harvesting, or one or several portable berry harvesters can be installed on the existing walking site or tractor to complete the harvesting work.

The harvester has the advantages of simple structure, high harvesting efficiency, low berry damage rate, small fruit branch damage, low cost, small vibration, convenient and reliable use, and meets the requirements of berry harvesting operations. Seabuckthorn, black currant, blueberry, wolfberry and other berries can be harvested, and walnuts, olives, hazelnuts, dates, apples, citrus and other crop fruits can also be harvested with a little modification.
