Description

Technical Field

[0001] The utility model relates to the technical field of corn harvesting machinery, in particular to a fresh corn harvesting, conveying and cleaning device and a harvester. Background Art

[0002] Corn is divided into three categories: grain corn, silage corn, and fresh corn. Grain corn is the most common corn we have. It is mainly harvested after the waxy ripe (when the moisture content is the lowest). It can be used as food in bad years and as feed or raw material for brewing in good years. The straw is used as fuel, returned to the field or stored for feeding livestock. Silage corn is mainly harvested as a whole plant in the late milky ripening stage. The cobs and stalks are crushed together and stored and fermented for use as animal husbandry feed. Fresh corn is similar to fruit. Its cobs are harvested in the early milky ripening stage (when the moisture content is the highest). It is mainly eaten by humans. The harvested straw is generally discarded and returned to the field, or used as backup silage for animal husbandry.

[0003] Compared with grain corn harvesting technology, my country's mechanical harvesting of fresh corn is still in the exploratory stage, and there are still many technical gaps. Since fresh corn is harvested in the early stage of milky maturity of the cob, the water content of corn stalks is high. During the harvesting process of fresh corn, some of the stalks in the corn cobs will be brought into the cob pile, and the stalks in the cob pile need to be cleaned later, increasing the intensity of manual labor. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a fresh corn harvesting, conveying and cleaning device and a harvester, which can realize the cleaning of fresh corn when harvesting fresh corn and save labor costs.

[0005] The utility model provides a technical solution to the above technical problems as follows: a device for harvesting, conveying and cleaning corn, comprising a frame, the frame being provided with an inclined corn ear elevator for conveying corn ears upward, the frame being provided with an corn ear box, the upper portion of the corn ear box being provided with an opening, the opening being provided beside the top of the corn ear elevator, an corn ear conveying mechanism being provided between the opening and the top of the corn ear elevator, the corn ear conveying mechanism being used for conveying corn ears conveyed to the top of the corn ear elevator from the opening to the corn ear box, and a cleaning fan being provided above the corn ear conveying mechanism for blowing out straw that falls onto the corn ear conveying mechanism.

[0006] The beneficial effect of the utility model is that the corn ears lifted up by the ear elevator are transported to the ear box by the ear conveying mechanism, and during the transportation by the ear conveying mechanism, the straw in the corn ears is blown away by the cleaning fan, so that the corn ears are cleaned and the labor cost caused by manual cleaning is reduced.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the height of the opening is lower than the top height of the ear elevator, and the ear conveying mechanism is an ear guide plate which gradually inclines downward from the top of the ear elevator toward the opening.

[0009] The beneficial effect of adopting the above further scheme is that the corn ears are transported to the top by the ear elevator and then fall from the top to the ear guide plate. Since the ear guide plate is inclined, the corn ears move into the ear box along with the ear guide plate under the weight of their gravity. The structure is simple and the cost is low.

[0010] Furthermore, the fruit ear conveying mechanism includes a fruit ear conveying belt.

[0011] The beneficial effect of adopting the above further scheme is that the ear conveying mechanism adopts an ear conveyor belt to realize the controllable speed conveyance of corn ears.

[0013] The beneficial effect of adopting the above further scheme is: a guide protrusion is provided on the conveyor belt to reduce the rolling of corn ears on the conveyor belt, and at the same time, corn ears at a low place can be transported to a high place.

[0014] Furthermore, the guide protrusion is a ridge whose length direction is perpendicular to the length direction of the conveyor belt.

[0015] The beneficial effect of adopting the above further scheme is: the convex ridges push the corn ears, thereby reducing the rolling of the corn ears on the conveyor belt and reducing the damage to the corn ears.

[0016] Furthermore, the object guiding protrusions are a plurality of object guiding protrusions evenly arranged on the conveyor belt.

[0017] The beneficial effect of adopting the above further solution is that the provision of the guide protrusion can increase the friction between the corn ears and the conveyor belt, thereby facilitating the conveyance of the corn ears.

[0018] Furthermore, the ear conveying mechanism and the cleaning fan are both detachably fixedly connected to the frame, an ear peeling machine and a press feeder are installed below the ear conveying mechanism, and the opening is arranged below the ear peeling machine and the press feeder.

[0019] The beneficial effect of adopting the above-mentioned further scheme is: the ear conveying mechanism and the cleaning fan are installed on the frame in a detachable manner, and then the ear peeling machine and the pressure conveyor are installed under the ear conveying mechanism. When it is necessary to harvest fresh corn, the ear conveying mechanism and the cleaning fan are installed on the frame. When harvesting grain corn, the ear conveying mechanism and the cleaning fan are removed from the frame. The grain corn is conveyed to the top by the ear elevator and falls into the ear peeling machine for peeling, and then conveyed to the ear box by the pressure conveyor.

[0020] The utility model solves the above-mentioned technical problems and also provides a harvester, including a cab, a driving wheel, a power mechanism, an ear picking cutting platform and the above-mentioned fresh corn harvesting, conveying and cleaning device, the cab is fixedly mounted on the frame, the driving wheel is arranged on the side of the frame, the power mechanism is mounted on the frame for driving the driving wheel, the ear picking cutting platform is mounted on the front end of the frame, and the bottom end of the ear elevator is connected to the outlet of the ear picking cutting platform for receiving corn ears.

[0021] The beneficial effect of adopting the above scheme is: driving the harvester to harvest fresh corn through the ear picking platform, and then transporting the picked fresh corn to the ear box through the ear elevator and the ear conveying mechanism in turn, and cleaning the ears during the transportation process, thereby reducing the labor cost caused by manual cleaning.

[0022] Furthermore, a straw recovery cutter is installed at the front end of the frame, a grass box is installed on the frame, a chopper is installed on the rear side of the straw recovery cutter for crushing the straw recovered by the straw recovery cutter, a straw throwing cylinder is fixedly installed on the frame, and the throwing fan is installed between the outlet of the chopper and the bottom end of the straw throwing cylinder for transporting the chopped straw to the grass box through the straw throwing cylinder.

[0023] The beneficial effect of adopting the above further scheme is: a straw recovery cutter is set on the frame, the recovered straw is crushed and then transported to the straw box through the straw throwing tube, so that both the stems and ears are collected. When the fresh corn is harvested, the corn straw has a high moisture content and is very suitable for recycling as feed.

[0024] Furthermore, a field return machine is installed in the middle of the bottom end of the frame.

[0025] The beneficial effect of adopting the above further scheme is that the setting of the corn stalk returning machine can clean up the corn stalks remaining in the field and return the remaining stalks to the field. BRIEF DESCRIPTION OF THE DRAWINGS
