Description

Technical Field

[0001] The utility model relates to the technical field of corn harvesting and bean harvesting machinery, in particular to a harvesting platform for harvesting beans and corn at the same time. Background Art

[0002] Corn harvester is an agricultural machine that uses machinery to harvest corn and stalks when corn is ripe. The emergence of corn harvester has greatly reduced the labor intensity of farmers, shortened the labor cycle of farmers, and saved them from heavy physical labor. Among them, the cutting table of corn harvester plays a pivotal role as an important part of the whole equipment. The role of corn harvester cutting table is to harvest and crush corn stalks and return them to the field, and collect corn ears on the stalks. The bean harvester is the same as the corn harvester. It is an agricultural machine that uses machinery to harvest beans and stems when beans are ripe. Among them, the cutting table of bean harvester also plays a pivotal role as an important part of the whole equipment. The role of bean harvester cutting table is to crush bean stems and return them to the field, and collect beans on the stems.

[0003] At present, the existing corn harvesters or bean harvesters only have a single harvesting function and cannot harvest these two crops at the same time. On the one hand, for ordinary farmers, it is economically stressful to own a corn harvester and a bean harvester at home; on the other hand, as people's understanding of ecological agriculture deepens, a variety of scientific and reasonable planting methods have gradually emerged, including inter-row planting of beans and corn. Compared with the traditional planting method, inter-row planting of beans and corn has great advantages and has gradually become the first choice of modern farmers. In the face of the new situation, there is an urgent need for a machine that can harvest these two crops at the same time. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a harvesting platform for simultaneously harvesting beans and corns, which has the function of simultaneously harvesting two crops, corn and beans.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a harvesting platform for simultaneously harvesting beans and corns, the harvesting platform comprising a frame, the frame being provided with 5 harvesting channels side by side, including 2 corn harvesting channels and 3 bean harvesting channels, the frame utilizing a differential lock arranged under the corn harvesting channel to connect the corn harvesting channel with the bean harvesting channel in an alternate arrangement, i.e., a 12121 arrangement (1 represents the bean harvesting channel, 2 represents the corn harvesting channel), the corn harvesting channel being able to adjust the harvesting speed of the corn harvesting channel to a suitable state according to a certain proportion under the connection of the differential lock, and independently complete the corn harvesting task; the bean harvesting channel being able to adjust the harvesting speed of the bean harvesting channel to a suitable state according to a certain proportion under the connection of the differential lock, and independently complete the bean harvesting task, thereby enabling the harvesting platform for simultaneously harvesting beans and corns to complete the operation of simultaneously harvesting the two crops.

[0006] The utility model is further improved in that: the corn harvesting channel includes a corn stalk guide groove, a corn stalk picking plate is provided at the bottom of the corn stalk guide groove, a grain-pushing chain is provided above the corn stalk picking plate and is supported on the corn stalk picking plate through a sprocket, the grain-pushing chain is connected with a differential lock and runs from front to rear, a stem-pulling roller is provided below the corn stalk picking plate and is connected with a differential lock to realize circular rotation, a cutting knife is provided below the stem-pulling roller and is connected with a differential lock to realize circular motion of the cutting knife, an upper ear transport plate is provided behind the corn stalk guide groove, and an upper auger is provided behind the upper ear transport plate.

[0007] The bean harvesting channel comprises a reel, a reel divider is arranged on the reel, a cutter is arranged under the reel, a lower ear conveying plate is arranged behind the reel, a lower auger is arranged behind the lower ear conveying plate, and the reel is connected to the reel main shaft by a differential lock to realize the circular motion of the reel.

[0008] The transmission mode of the upper ear conveying plate is belt drive.

[0009] The transmission mode of the lower ear conveying plate is belt drive.

[0010] The internal transmission mode of the differential lock is gear transmission.

[0011] There are small hydraulic cylinders inside the differential lock to properly adjust the distance between the corn harvesting header and the bean harvesting header.

[0012] The beneficial effect of adopting the above technical scheme is that the present invention combines the corn harvester header with the bean harvester header to form a corn and bean simultaneous harvesting header: the two sides and the middle of the header are bean harvesting headers, and the space between the two bean harvesting headers is a corn harvesting header to adapt to the inter-row planting method of beans and corn, so that the front end of the header forms a harvesting work area as a whole. When harvesting corn and beans, it is only necessary to install the corn and bean simultaneous harvesting header on the corresponding machine, and adjust the distance between the corn harvesting header and the bean harvesting header. After adjusting the distance, since the corn harvesting header is longer than the bean harvesting header, you only need to align the corn harvesting header without aligning the bean harvesting header again to start working. Compared with first harvesting corn with a corn harvester and then harvesting beans with a bean harvester, it avoids repeated operations, saves the second harvesting, saves labor and losses (according to statistics, it takes one hour to harvest crops planted between beans and corn using a header that harvests both beans and corn at the same time, and it takes three hours for a corn harvester and a bean harvester to harvest successively, saving at least half of the cost).

DETAILED DESCRIPTION

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1As can be seen from the embodiment shown in the overall structural schematic diagram, this embodiment includes a frame 1, and the frame 1 is provided with 5 harvesting channels in parallel, including 2 corn harvesting channels 2 and 3 bean harvesting channels 3. The frame 1 uses the differential lock 4 arranged under the corn harvesting channel 2 to connect the corn harvesting channel 2 and the bean harvesting channel 3 in an alternate arrangement, that is, a 23232 arrangement (2 represents the corn harvesting channel, and 3 represents the bean harvesting channel). The corn harvesting channel 2 can adjust the harvesting speed of the corn harvesting channel to a suitable state according to a certain proportion under the connection of the differential lock 4, and independently complete the corn harvesting task; the bean harvesting channel 3 can also adjust the harvesting speed of the bean harvesting channel to a suitable state according to a certain proportion under the connection of the differential lock 4, and independently complete the bean harvesting task, so that the harvesting platform for simultaneously harvesting beans and corn can complete the operation of simultaneously harvesting the two crops.

[0020] The corn harvesting channel includes a corn stalk guide groove 2-1, at the bottom of which is an ear picking plate 2-2, above which is a rice-pulling chain 2-3 supported on the ear picking plate 2-2 by a sprocket 2-4, the rice-pulling chain 2-3 connected by a differential lock 4 to run from front to rear, below which is a stem pulling roller 2-5 connected by a differential lock 4 to achieve circular rotation, below which is a stem pulling roller provided with a cutting knife 2-6 connected by a differential lock 4 to achieve circular motion, behind which is an upper ear transport plate 2-7, and behind which is an upper auger 2-8.

[0021] The bean harvesting channel 3 includes a reel 3-1, a reel divider 3-2 is provided on the reel, a cutter 3-3 is provided below the reel, a lower ear transport plate 3-4 is provided behind the reel 3-1, a lower auger 3-5 is provided behind the lower ear transport plate 3-4, and the reel is connected to the reel main shaft 3-6 by a differential lock 4 to rotate to realize the circular motion of the reel 3-1.

[0022] By connecting the reel main shaft 3-6 in the bean harvesting channel 3 with the differential lock 4 under the corn harvesting channel 2, the bean harvesting channel 3 and the corn harvesting channel 2 are connected, so that the bean harvesting channel 3 and the corn harvesting channel 2 are harvested simultaneously.

[0023] The transmission mode of the upper ear conveying plate 2-7 is belt drive.

[0024] The transmission mode of the lower ear conveying plate 3-4 is belt drive.

[0025] The internal transmission mode of differential lock 4 is gear transmission.

[0026] A small hydraulic cylinder is arranged inside the differential lock 4 to properly adjust the distance between the corn harvesting header and the bean harvesting header.

[0027] Working principle: When it is necessary to harvest the land interplanted with beans and corn, install the bean and corn simultaneous harvesting header on the machine body. Since the bean and corn simultaneous harvesting header has both the corn harvesting header and the bean harvesting header, it is only necessary to control the hydraulic cylinder in the differential lock to adjust the distance between the corn harvesting header and the bean harvesting header, and then align the rows through the corn header. After aligning the rows, the machine can start normal work. During operation, the gear transmission inside the differential lock can adjust the speed of the main shaft of the reel of the bean harvesting channel, so that the harvesting speeds of the corn harvesting channel and the bean harvesting channel match, and better complete the operation of harvesting these two crops, corn and beans, at the same time.
