Description

Small-sized red date harvester

Technical Field

The invention relates to a mechanical device for assisting manual jujube picking, in particular to a small-sized red jujube harvester.

Background

According to investigation, the work of picking, collecting and screening the red dates accounts for about 30% of the work load of planting the red dates, and small and medium-sized (10-200 mu) jujube garden planters account for about 74.9% of the jujube planters along with the increase of the planting area of the red dates.

At present, the mode of picking red dates in small and medium-sized date gardens is mostly manual work and hits the branch through the stock, makes the branch produce vibration, vibrates the red date from the branch, later picks up the red date on the ground on hand. This approach is both laborious and inefficient. The mechanized picking of red dates abroad applies a full-automatic red date picking machine, but the volume is large, the requirement on the row spacing of the date trees is high, and therefore, the machine is not suitable for picking and collecting the small and medium-sized date gardens. In order to solve the problem, a red date picking and collecting device is designed. The device has liberated and has picked, collected the red date hard, inefficiency, inconvenient three problem. Therefore, the importance of the mechanized operation of red dates in red date picking is gradually highlighted. Aiming at the problems that the existing small and medium jujube orchard mostly depends on manual long-rod jujube beating, the physical strength is consumed, and the efficiency is low.

In order to achieve the purpose, the technical scheme of the invention is as follows:

the small red date harvester comprises a small red date harvester main body, wherein the small red date harvester main body comprises a fixed frame, four universal wheels are arranged at the lower end of the fixed frame, a motor is arranged in the fixed frame, the motor is connected with a crank through a coupler, the crank is connected with a vertically upward connecting rod, a clamping hook is arranged at the top end of the connecting rod, a picking rod capable of sliding along the connecting rod is sleeved outside the connecting rod, a locking buckle is arranged at the bottom end of the picking rod, a picking head is arranged at the top end of the picking rod, and the clamping hook and the picking head jointly form a clamping and locking device; the collecting net is arranged above the fixed rack through the collecting net supporting rod, the lower end of the collecting net is provided with an opening, the opening is over against the screening net arranged at the upper end of the fixed rack, and the collecting box is arranged below the screening net.

Furthermore, a ventilator is arranged between the opening at the lower end of the collecting net and the screening net on one side above the fixed rack.

Furthermore, the screening net is provided with pore strips with different sizes, and the pore strips with different sizes are respectively provided with an independent collecting box.

Furthermore, the collection net supporting rod is of a telescopic folding structure.

Furthermore, the connecting rod is of a telescopic structure.

Compared with the prior art, the invention has the following beneficial effects:

the invention uses the crank-slider mechanism in the aspect of structural design, and the slider is connected with the connecting rod, thereby improving the jujube picking efficiency; the rotation of the motor is converted into the vertical motion of the connecting rod, the branches are pulled to generate high-frequency vibration, and the collecting and screening device is matched with the branches, so that the red dates fall into the collecting net. Instead of manual collection and screening. The device integrates the three functions of picking, collecting and screening, invents a small-sized red date harvester integrating picking, collecting and screening, has a simple mechanism and convenient use, realizes the purposes of picking the red dates by an electric drive machine, liberating labor force and filling the blank of a high-efficiency small-sized red date picking instrument in the market. The method is suitable for small and medium-sized mature red date gardens, and can reduce the workload by about 30% in the red date planting process.

Detailed Description

The present invention will be described in further detail with reference to the following detailed description and accompanying drawings. Wherein like elements in different embodiments are numbered with like associated elements. In the following description, numerous details are set forth in order to provide a better understanding of the present application. However, those skilled in the art will readily recognize that some of the features may be omitted or replaced with other elements, materials, methods in different instances.

Example (b):
