Description

Fruit picking rod based on slider-crank mechanism

Technical Field

The invention discloses a crank-slider mechanism based on a fruit picking device, and belongs to the field of mechanical devices.

Background

In recent years, with the continuous improvement of the living standard of people in China, the demand of people for fruits and vegetables is increasing day by day. To meet the needs of consumers, the yield of various crops is increased. In the whole fruit production process, the fruit picking operation is the most time-consuming and most labor-consuming link in the fruit production chain. The picking operation has strong seasonality, large labor intensity and high cost, so that the timely picking of fruits is ensured, and the reduction of the harvesting operation cost is an important way for increasing the agricultural income. Due to the complexity of the picking operation, the degree of picking automation is still low. On the other hand, the quality of picking quality directly influences the subsequent work such as fresh-keeping storage, transportation and distribution. If the original manual picking is continued, not only the working environment is very hard and the efficiency is low, but also the fruit picking quality can not be guaranteed, and even the accidents that picking workers are injured due to the careless falling from trees due to the complex environment in the picking process occur occasionally. At present, various pickers are available in the market, but in the actual picking process, fruit growers often touch the fruit growing angle and are too fiddly, and the conventional pickers are difficult to pick or reluctant to pick but are easy to damage fruits. The picking machine is used for improving the picking efficiency, reducing the damage rate, saving the labor cost and improving the economic benefit of fruit growers, so that the picking machine has important significance for improving the mechanization degree of picking operation.

Disclosure of Invention

The invention provides a fruit picking rod based on a slider-crank mechanism, and provides a picking rod capable of self-adapting to various picking angles, aiming at the phenomenon that the fruit growth angle is too narrow during the actual picking process, and the conventional picker is difficult to pick or reluctant to pick but easy to damage fruits.

The invention mainly adopts the technical scheme that:

the utility model provides a pole is picked to fruit based on slider-crank mechanism, includes hollow pole, main part pole, slider, slope pole, connecting rod and picks the handle, hollow pole top articulates on fruit picking device through the hinged-support, and the end is installed and is picked the handle, open on the upper portion of hollow pole has first elongated slot, and open the lower part has the second elongated slot, the main part pole sets up in hollow pole, the one end of main part pole is connected with the one end of slope pole in first elongated slot department, and the other end is connected with the slider in second elongated slot department, the other end of slope pole is articulated with connecting rod one end, the connecting rod other end articulates on fruit picking device, be equipped with the sliding handle on the slider, just the second elongated slot department opens and has a plurality of gear grooves, sliding handle and gear groove cooperation buckle.

Preferably, there are three of the shift grooves.

Preferably, hollow pole is the aluminum alloy material, the main part pole is carbon fiber material.

Has the advantages that: the invention provides a fruit picking rod based on a slider-crank mechanism, which is used for picking fruits at different angles by controlling the slider-crank mechanism, thereby not only improving the picking efficiency, but also reducing the damage rate, saving the labor cost and improving the economic benefit of fruit growers.

Detailed Description

In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application are clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The technical scheme of the invention is further explained in detail by combining the attached drawings:

a fruit picking rod based on a slider-crank mechanism comprises a hollow rod 1, a main body rod 2, a slider 3, an inclined rod 4, a connecting rod 5 and a picking handle 6, wherein the top end of the hollow rod 1 is hinged on a fruit picking device through a hinged support 8, the tail end of the hollow rod is provided with the picking handle 6, the upper part of the hollow rod 1 is provided with a first long groove 1-1, the lower part of the hollow rod 1 is provided with a second long groove 1-2, the main body rod 2 is arranged in the hollow rod 1, one end of the main body rod 2 is connected with one end of the inclined rod 4 at the position of the first long groove 1-1, the other end of the main body rod 2 is connected with the slider 3 at the position of the second long groove 1-2, the other end of the inclined rod 4 is hinged with one end of the connecting rod 5, the other end of the connecting rod 5 is hinged on the fruit picking device 7, the slider 3 is provided with the sliding handle 3-1, and a plurality of gear grooves 3-2 are arranged at the positions of the second long groove 1-2, the sliding handle 3-1 is matched with the gear groove 3-2 in a buckling mode.

Preferably, there are three of the shift grooves 3-2.

Preferably, hollow rod 1 is the aluminum alloy material, main part pole 2 is the carbon fiber material.
