Description

Technical Field

[0001] The present invention belongs to the field of agricultural machinery, and particularly relates to a harvester. Background Art

[0002] With the continuous maturity of harvesting machinery technology, corn harvesting has gradually got rid of the time-consuming and laborious manual harvesting. However, due to the differences in plot sizes, agronomic conditions, and farmers' income levels in different regions, different configuration models need to be targeted for different regions to meet user needs. Currently, the main row spacings for planting in the main sales regions of the market are 550 mm and 600 mm. There are also some row spacings of 650 mm and 700 mm in the eastern region of Shandong. The area of each household is relatively small, and the harvested plots are mostly 2 - 5 mu.

[0003] Due to the large differences in corn agronomy and the physical characteristics of crops in different regions, it is impossible to use a single harvester structure for cross-regional harvesting in the country like wheat and rice. It is precisely because cross-regional operations can bring better harvesting benefits to machine operators that has promoted a substantial increase in the sales of wheat and rice harvesters, and naturally also driven a rapid increase in the mechanized harvesting rate. The main problems in corn agronomy are mainly reflected in the large differences in corn harvesting states in different regions, the large differences in moisture contents of different corn varieties during harvesting in different regions. At the same time, due to different agronomies in each region and inconsistent corn planting row spacings, it also seriously hinders cross-regional operations. Summary of the Invention

[0004] In order to solve the above technical problems, the purpose of the present invention is to provide a harvester with a simple structure and adjustable harvesting row spacing.

[0005] To achieve the above purpose, the technical solution of the present utility model is as follows: A harvester includes a harvester body.

DETAILED DESCRIPTION

[0041] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0042] Example 1

[0043] like Figure 1 As shown, this embodiment provides a straw divider, including a straw divider body 111, a telescopic member 112 and a rocker arm 113, the rocker arm 113 is rotatably mounted on the front end of the straw divider body 111, the telescopic member 112 is rotatably mounted on the straw divider body 111, and its telescopic end faces forward and is transmission-connected to the middle part of the rocker arm 113, the telescopic member 112 extends or contracts to drive the rocker arm 113 to swing left and right relative to the straw divider body 111, and the telescopic member is used to drive the rocker arm to swing left and right to achieve adjustment of its width.

[0044] The telescopic member 112 in the above technical solution is a hydraulic cylinder, a telescopic air cylinder or a telescopic electric cylinder, which has a simple structure and is convenient to telescope.

[0045] Preferably, the front end of the rocker arm 113 in the above technical solution is also rotatably mounted with a horizontally arranged tensioning wheel 114, so that the tensioning wheel can be used to achieve rolling contact when the front end of the rocker arm contacts an external object, thereby preventing the rocker arm from sweeping down crops or preventing the rocker arm from being released from the ridge and inserted into the soil.

[0046] like Figure 2 As shown, the rocker arm 113 in the above technical solution includes a sleeve 1131, a rod body 1132, a slide rod 1133 and an elastic member 1134. The sleeve 1131 is horizontally arranged along the front and rear directions, and its rear end is rotatably connected to the front end of the divider body 111. One end of the rod body 1132 extends into the sleeve 1131 through the front end of the sleeve 1131 and can slide back and forth relative to the sleeve 1131. The tensioning wheel 114 is rotatably mounted on the front end of the rod body 1132. The slide rod 1133 is parallel to the sleeve 1131. A first connecting block 11321 is convexly provided on the front end side wall of the rod body 1132. A connecting block 11321 is fixedly connected to the front end of the sliding rod 1133, and a second connecting block 11311 is protruding from the side wall of the front end of the sleeve 1131. The sliding rod 1133 is slidingly connected to the second connecting block 11311, and the elastic member 1134 is placed between the first connecting block 11321 and the second connecting block 11311. Its elastic tension tends to drive the rod body 1132 to move forward. The telescopic end of the telescopic member 112 is rotatably connected to the middle part corresponding to the length direction of the sleeve 1131. Its structure is simple, so that the rocker arm has a damping telescopic function.

[0050] Embodiment 2

[0051] As Figure 3 shown, this embodiment provides a cutting table, including a cutting table body 10. The two outermost dividing headers 11 of the cutting table body 10 are both the dividing headers as described in Embodiment 1, and the two telescopic members 112 extend or contract synchronously to drive the two swing rods 113 to swing so that their front ends approach or move away from each other to adjust the row spacing of the cutting table body 10. In this way, the swing rods on the two outermost dividing headers of the cutting table body swing outwards respectively to adjust the row spacing of the entire cutting table.

[0052] Embodiment 3

[0053] As Figure 4 shown, this embodiment provides a harvester, including a harvester body 100, and the cutting table 1 on the front side of the harvester body 100 is the cutting table as described in Embodiment 2. By adopting the cutting table with adjustable row spacing as above, the harvester can adjust the row spacing.

[0054] As Figure 5 and Figure 6 and Figures 12 - 14As shown, the seat 2 at the co-pilot position in the cab of the harvester body 100 in the above technical solution is a vehicle-mounted folding chair, so that the co-pilot seat can be unfolded into a rest bed for the driver to lie down and rest during rest. The co-pilot seat can also be slidably installed in the cab, and it can slide back and forth to adjust its front and rear space to facilitate the unfolding of the vehicle-mounted folding chair (such as the front seat of a car). Of course, the vehicle-mounted folding seat can also include a seat plate 21, a back plate 22 and two strip racks 23 arranged at intervals along the left and right directions, and each of the strip racks 23 is horizontally arranged along the front and rear directions, and a shelf bar 231 is provided between the front lower ends of the two strip racks, and the shelf bar 231 is connected and fixed to the two strip racks 23. 1 is horizontally arranged between the two strip frames 23, and the back plate 22 is vertically arranged between the two strip frames 23 and located behind the seat plate 21. At this time, the seat plate 21 and the back plate 22 are distributed in a "┘" shape (to facilitate sitting), and the front lower end of the seat plate 21 is rotatably connected to the front ends of the two strip frames 23, and the rotation connection is located behind the shelf bars 231. The lower rear end of the back plate 22 is rotatably connected to the rear ends of the two strip frames 23. The seat plate 21 is rotated forward to be horizontal and rests on the shelf bars 231. The back plate 22 can be rotated forward to be horizontal and is located behind the seat plate 21, and the two are distributed in a "I" shape (to facilitate workers lying down).

[0055] In the above technical solution, a field returner 3 and a driving member are slidably installed at the lower end of the chassis of the harvester body 100. The driving member is transmission-connected to the field returner 3. The driving member is used to drive the field returner 3 to move left and right at the lower end of the chassis, so that the field returner on the harvester body can adjust its left and right position according to the row spacing adjustment of the cutting platform.

[0056] The driving member in the above technical solution is a hydraulic cylinder, a telescopic air cylinder or a telescopic electric cylinder, which has a simple structure and is easy to drive. The installation method of the driving member is common knowledge to those skilled in the art, so it will not be described here.

[0057] like Figure 8 As shown, the harvester body 100 in the above technical solution is provided with a domestic water tank 5 and / or a tool box 6. The domestic water tank can be filled with clean water for the driver to wash, and the tool box can be used to hold various maintenance tools. The domestic water tank and the tool box are respectively installed on the rear side of the cab and are located on the left and right sides of the rear side of the cab. The tool box is an existing conventional tool box with a lid (the lid can be equipped with a lock for anti-theft). The domestic water tank includes a box body 51 with a water inlet at the upper end (the box body 51 is fixed to the rear side of the cab), an openable or closable lid 52 at the water inlet, a water outlet at the lower end of the box body, and a faucet 53 at the water outlet.

[0058] As Figure 7 shown, in the above technical solution, the control lever 7 in the cab of the harvester body 100 is a retractable control lever (the core lies in height adjustment). In this way, when resting, the control lever can be folded to create more space in the cab. The control lever 7 includes a vertically arranged lever sleeve 71 and a lever body 72. The lower end of the lever body 72 extends into the lever sleeve 71, and the depth of its extension into the lever sleeve is adjustable. A locking bolt 73 is threadedly connected to the side wall at the upper end of the lever sleeve, and the threaded end of the locking bolt extends into the lever sleeve. Tighten the locking bolt to lock the lever body on the lever sleeve, or loosen the locking bolt to make the lever body adjustable up and down to adjust the height of the control lever. The lower end of the lever sleeve is the lower end of the control lever.

[0059] In the above technical solution, the transmission of the harvester body 100 is a torque-increasing continuously variable transmission, so that the harvesting speed can be matched with the traveling speed of the harvester body. This belongs to the prior art and will not be elaborated here. The structure can be similar to that disclosed in the document with the document number CN204392881U, "New Type of Harvester Drive Axle Torque-Increasing Continuously Variable Transmission Device".

[0060] As Figure 9 and Figure 10 shown, in this embodiment, the harvester body is a wheeled harvester. Since the row spacing of its cutting table is adjustable, in order to make the performance of the harvester body optimal, the wheel hub 92 of each wheel can be installed forward or backward at both ends of the wheel axle 91 to adjust its wheelbase.

[0061] Among them, as Figure 11 in this embodiment, the grain discharging mechanism of the harvester body can adopt a grain unloading tube 81 or a grain lifting device 82. The grain outlet of the grain discharging device 8 of the harvester body is connected to the grain inlet of the discharging mechanism in a detachable connection manner (such as flange connection). In this way, the interchange of the two grain discharging mechanisms, namely the grain unloading tube 81 and the grain lifting device 82 (either the grain unloading tube 81 or the grain lifting device 82), can be realized to meet the needs of different regions or farmers.

[0062] The harvester provided in this embodiment can be particularly applied to a corn harvester.

[0063] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
