Handheld type branch vibration and fruit harvesting device

Abstract

The invention relates to a handheld type branch vibration and fruit harvesting device and belongs to the technical field of fruit harvesting. The handheld type branch vibration and fruit harvesting device comprises a driving mechanism, a transmission mechanism, a vibration mechanism, a vibration-reducing handheld mechanism, a manual clamping mechanism, a branch clamping head and a ratchet wheel locking mechanism. The driving mechanism, a transmission mechanism, a vibration mechanism, a vibration-reducing handheld mechanism and a manual clamping mechanism are connected in sequence. The manual clamping mechanism comprises a crank push rod mechanism which controls clamping or loosening motions of the branch clamping head through forward direction or reverse rotation and is driven by a clamping handle. The ratchet wheel locking mechanism has a locking gear for controlling single forward direction rotation of the clamping handle and an unlocking gear for controlling forward direction or reverse direction rotation of the clamping handle. The handheld type branch vibration and fruit harvesting device can quickly clamp fruit tree branches and adjust vibration amplitude and frequency to perform vibration harvesting of fruits, improve fruit harvesting efficiency, reduce cost and alleviate damage to the fruit tree branches. The vibration-reducing handheld mechanism is adopted to prevent vibration fatigue damage to operators.

Description

technical field [0001] The invention relates to a fruit harvesting device, in particular to a hand-held branch vibrating fruit harvesting device. Background technique [0002] At present, the domestic fruit harvesting process is basically manual harvesting. The demand for labor is high, the labor intensity is high, and the harvesting cost is high. Especially in recent years, the lack of rural labor has made fruit harvesting a bottleneck restricting fruit production. In order to reduce the cost of fruit harvesting, a lot of research has been done on fruit mechanized harvesting at home and abroad in recent years. Mechanical vibration fruit harvesting has attracted widespread attention due to its high harvesting efficiency, especially the harvesting speed of tree trunk vibration and crown vibration harvesting is as high as 30-80 plants / hour. However, these two types of vibratory harvesting equipment are large in structure and require high-horsepower tractors to drive, so they ...

The invention patent with authorized notification number CN103229632B discloses a kind of near-fruit vibrating litchi harvester, which utilizes a vibrating comb to insert into the fruit tree crown and make the fruit vibrate and fall off. This invention is suitable for vibrating harvesting of litchi and longan-type fruit trees. The harvesting efficiency of non-bunch fruit trees is low by the way of vibrating comb

The utility model patent with the authorized notification number CN202285603U discloses a portable fruit vibration harvesting device, which uses the hook vibration unit to hook the branches to vibrate and make the fruit vibrate and fall off. This scheme is applicable to most fruit trees, but due to the use of the hook Hooking the branches, the hook vibration type is easy to fall off and has a great impact on the branches, which is easy to damage the branches

[0004] The prior art has the following shortcomings: 1. The vibration amplitude and vibration frequency are different when different fruits are harvested without consideration and solution. For this, it is necessary to conveniently adjust the vibration amplitude and vibration frequency of the vibration mechanism; 2. There is no fast clamping of fruit tree branches 3. Failure to consider and solve the problem of vibration fatigue damage to the operator's arm under high-frequency vibration
