Description

Tumbling Pineapple Harvester

technical field

The invention discloses a large-scale tumbling pineapple harvester, which relates to the fields of agricultural production and the like.

Background technique

In recent years, with the large-scale and high-yield pineapple planting, the problem of picking pineapple after it matures has become increasingly prominent. At present, the commonly used method is manual picking. There are usually two methods. One is that a person carries a basket, breaks the pineapple off the tree, and then puts it lightly in the basket. Usually, a basket can only hold a few to a dozen pineapples. When the basket is full, the basket is transported to the collection point; the other is multi-person cooperation, one person specifically breaks off the pineapples, and several people form a queue to pass the picked pineapples to the collection point. Manual harvesting of pineapples is inefficient and labor-intensive, and the demand for a small pineapple harvesting machine that can provide high efficiency and labor-saving is increasingly strong. In this regard, in order to improve the efficiency of pineapple picking and save manpower and material resources, we disclose a rolling pineapple harvester that can be picked on a large scale.

Contents of the invention

The main problem to be solved in the present invention is to provide a labor-saving and labor-saving tumbling pineapple harvester for the problem that a large amount of manpower and material resources are wasted in the current traditional pineapple picking method.

The technical scheme mainly adopted in the present invention is:

The tumbling pineapple harvester includes picking parts, collecting parts, lifting parts, power transmission parts, and supporting parts. Chassis cover, collection box, lifting parts include control handle, scraper mounting frame, balance spring, power transmission parts include differential, drive motor, one-in-two-out gearbox, scraper drive shaft, scraper shaft, scraper The power transmission mechanism and the front wheel power transmission mechanism, the support components include a vehicle frame, two driving wheels, and two universal wheels.

The picking part is arranged at the front end of the frame, the collecting part is at the rear end of the frame, the lifting part is on the overall upper part of the frame, the power transmission part is placed under the connection between the picking part and the collecting part, and the transmission part provides the collecting part and the supporting part Running power.

The scraper is installed on the scraper mounting brackets on both sides of the separation frame through its scraper shaft. The second half of the separation frame is a circular arc transition surface, which is concentric with the scraper shaft and has an arc surface and the outermost edge of the scraper. The small gap ensures that the pineapple will not fall after picking and can also be taken to the collection part by the scraper. The separation frame is installed on the frame, and the middle is transitioned by the inclined chassis cover, which is convenient for the pineapple to slide from the separation frame to the frame. In the box, the collection box is placed at the rear of the frame. Since the rear of the frame is provided with a bracket with a slot, the collection box is placed on the bracket and fixed by the slot to facilitate the replacement of the collection box. The drive motor, one-in two-out gearbox and differential are placed under the case cover to save space. The one-in-two-out gearbox divides the power input by the motor into two outputs, which can provide power for the movement of the pineapple harvester and the rotation of the scraper at the same time. One end of the control handle is fixedly placed on the upper part of the scraper mounting frame on both sides of the separation frame, and the electric control switch is installed near the handrail at the rear end. The control handle is used to control the steering of the whole machine, the height of the picking parts and the operation of the whole machine. The differential and the output shafts at both ends together form the front axle, which can make the left and right driving wheels rotate at different speeds, ensuring that the driving wheels do not interfere when the harvester turns. The overall harvester is compact, easy to use, saves manpower and material resources, and greatly reduces the difficulty of picking pineapples.

The beneficial effects of the present invention are: compared with the prior art, it provides an efficient and labor-saving small pineapple harvesting machine, which improves the pineapple picking efficiency and saves manpower and material resources. The device fixes the stem of the lower part of the pineapple within a certain range, and the rotation of the scraper gives the pineapple a lateral force, causing the pineapple fruit to be separated from the stem, so as to achieve the purpose of picking. The picked pineapple will roll along the cover of the case into the collection box , to achieve the purpose of collection.

The advantages of the present invention are:

1. The invention is a tumbling pineapple harvester, which realizes efficient picking of pineapples and saves manpower and material resources.

2. The present invention can be adapted to different types of pineapple fields, and one cart can be used for multiple purposes.

3. The present invention can lift the front part of the frame, so that the separation frame of the picking parts can adapt to the picking of pineapples at different heights.

4. The power transmission part of the present invention adopts a gearbox with one input and two outputs, which divides the power of the drive motor into two paths, and simultaneously provides the forward power of the pineapple harvester and the power for picking pineapple.

5. The driving wheel part of the present invention adopts a differential, and the differential operation of the two driving front wheels can realize the steering of the pineapple harvester, simplifying the structure.

6. The present invention adopts four wheels, so that the whole vehicle is more stable, and it is convenient to run in rough fields.
