Description

Technical Field

[0001] This utility model relates to the field of slashing and drying machines, specifically to a slashing and drying machine horizontal conveying device and a slashing and drying machine. Background Technology

[0002] In the field of agricultural harvesting machinery, a stalk harvester is a specialized piece of equipment used to harvest crops such as rice, wheat, and rapeseed and spread them out in the field to dry. Its workflow typically includes three main stages: cutting, conveying, and spreading. The conveying mechanism's role is to promptly and orderly transport the crop stalks cut by the header to one side of the machine, forming strips that facilitate subsequent collection.

[0003] Currently, the conveying mechanisms of existing crop stalk harvesters mostly adopt the form of flat belts, scraper chains, or toothed conveyors. When these mechanisms are working, they primarily provide a single, lateral conveying force perpendicular to the machine's forward direction. As a result, the cut crop stalks largely maintain their original posture when cut during transport, meaning the stalk's axis is roughly parallel to the machine's forward direction, and they are ultimately laid out in the field in a "translational" manner.

[0004] However, this traditional method of conveying and laying has a significant drawback: in the resulting strips, the straw is laid vertically along the direction of the machine's movement. This laying pattern causes the following problems for subsequent picking operations: Firstly, the picking efficiency is low. The picking teeth or rollers of picking tools (such as pickers) usually rotate in the same direction as the horizontal direction of the strips. For vertically laid straw, the picker has difficulty picking it up continuously and smoothly from the bottom, which can easily cause the straw to become entangled, blocked, or missed, seriously affecting the picking efficiency and the smoothness of the operation.

[0005] Secondly, the strip-laying structure is loose. The vertically laid straw has poor interweaving, and the strips are loose and irregular, which is not only not conducive to drying in the field, but also makes it difficult for the picker to grab a concentrated and compact stream of straw, resulting in uneven feeding and affecting the quality of subsequent threshing or baling.

[0006] Third, it increases power consumption and losses. Due to the high resistance and uneven picking process, the picking equipment needs to consume more power, which also increases the loss of straw and grains.

[0007] Therefore, it is urgent to solve the above-mentioned technical problems. Summary of the Invention

[0008] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a horizontal conveying device for a stalk cutter, which can turn the cut crop straw during the conveying process, and finally form a horizontal strip of straw with the straw axis perpendicular to the machine's forward direction, which is convenient for picking up.

[0009] To solve the above-mentioned technical problems, the technical solution of this utility model is: a horizontal conveying device for a stalking and drying machine, comprising: The support frame is used for mounting on the threshing machine; Two conveyor belt mechanisms are installed side-by-side on the support frame for conveying crop straw cut by the cross-cutting blades of the harvester in the same direction; wherein... The linear velocity of the conveyor belt mechanism closer to the cross-cutting blade is less than that of the conveyor belt mechanism farther away from the cross-cutting blade.

[0010] Furthermore, in order to better transport and rotate the cut crop straw, the outer surface of the conveyor belt of the conveyor belt mechanism is an anti-slip surface.

[0011] A further specific anti-slip measure is provided, wherein multiple anti-slip strips are spaced apart along the conveying direction of the conveyor belt on the outer surface of the conveyor belt to form the anti-slip surface.

[0012] Furthermore, after the support frame is installed on the stalker, it is inclined upwards from the end closest to the horizontal cutter to the end furthest from the horizontal cutter.

[0013] Furthermore, the drive shafts of the two conveyor belt mechanisms are connected via a gearbox.

[0014] Furthermore, the ratio of the linear velocity of the conveyor belt farther from the cross-cutting blade to the linear velocity of the conveyor belt mechanism closer to the cross-cutting blade is 2 to 3.

[0015] Furthermore, the support frame includes a square frame and a central beam installed in the middle of the square frame, the central beam simultaneously supporting the adjacent sides of the conveyor belts of the two conveyor belt mechanisms.

[0016] Furthermore, in order to achieve half-width harvesting, the length of the support frame is less than the length of the cross-cutting blade.

[0017] This utility model also relates to a stalking machine, including a stalking machine horizontal conveying device.

[0018] Furthermore, to prevent the cut crop stalks from becoming entangled with unharvested crop branches on the sides and thus unable to fall over, the reaper also includes longitudinal cutting blades for cutting the side branches of the crops.

[0019] After adopting the above technical solution, the crop straw cut by the cross-cutting blade of the harvester lies backward on the two conveyor belt mechanisms. The conveying speed of the front conveyor belt mechanism is slower than that of the rear conveyor belt mechanism, so that the head of the crop straw is conveyed at a faster speed during the process of being transported to the side, thus causing it to turn and form a horizontal spread that is almost perpendicular to the direction of machine movement. This creates a concentrated and compact straw flow, which facilitates subsequent collection, improves collection efficiency, and also improves the quality of subsequent threshing and baling, while reducing energy consumption and straw grain loss.

[0021] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0022] Example 1

[0023] like Figure 1 and Figure 2 As shown, a cross-laying conveyor device for a stalker includes: The support frame 1 is used for mounting on the threshing machine 10; Two conveyor belt mechanisms 2 are mounted side-by-side on the support frame 1 for conveying crop straw cut by the cross-cutting blades 101 of the stalk harvester 10 in the same direction; wherein, The linear velocity of the conveyor belt mechanism 2 closer to the transverse cutter 101 is less than the linear velocity of the conveyor belt mechanism 2 farther from the transverse cutter 101. Crops may include, but are not limited to, rapeseed, wheat, and rice.

[0024] Specifically, the crop straw cut by the cross-cutting blade 101 of the harvester 10 lies backward on the two conveyor belt mechanisms 2. The conveying speed of the front conveyor belt mechanism 2 is slower than that of the rear conveyor belt mechanism 2, so that the head of the crop straw is conveyed at a faster speed during the process of being conveyed to the side, thereby turning and forming a horizontal spread that is approximately perpendicular to the direction of machine movement. This creates a concentrated and compact straw flow, which facilitates subsequent collection, improves collection efficiency, and also improves the quality of subsequent threshing and baling, while reducing energy consumption and straw grain loss.

[0025] In this embodiment, to prevent the cut crop straw from slipping during the conveyor belt mechanism 2, preferably, as follows: Figure 1As shown, the outer surface of the conveyor belt 21 of the conveyor belt mechanism 2 is an anti-slip surface. There are various ways to form the anti-slip surface. For example, multiple raised anti-slip strips 3 are arranged at intervals along the conveying direction of the conveyor belt 21 on the outer surface of the conveyor belt 21. Another example is to set anti-slip patterns on the outer surface of the conveyor belt 21, etc.

[0026] In this embodiment, as Figure 1 As shown, preferably, after the support frame 1 is installed on the reamer 10, it is inclined upward from the end near the horizontal cutter 101 to the end away from the horizontal cutter 101.

[0027] In this way, after the cut crop stalks are laid on the two conveyor belt mechanisms 2, the head is conveyed at a faster speed due to the speed difference between the two conveyor belt mechanisms 2, and then falls under the action of gravity, so as to achieve a better 90-degree flip and better horizontal laying.

[0028] In this embodiment, as Figure 2 As shown, preferably, the drive shafts 22 of the two conveyor belt mechanisms 2 are connected by a gearbox 4.

[0029] In this way, two conveyor belt mechanisms 2 can be driven simultaneously at different linear speeds by the same power mechanism. This power structure can be integrated into the cross-laying conveyor of the slasher, or it can be powered by the slasher itself.

[0030] In this embodiment, the ratio of the linear velocity of the conveyor belt 21 farther from the cross-cutting blade 101 to the linear velocity of the conveyor belt mechanism 2 closer to the cross-cutting blade 101 can be 2 to 3. This ratio depends on the length of the specific crop. For example, for a type of straw in Qinghai that is about 1.6 meters long, the linear velocity ratio is 36:14.

[0031] In this embodiment, as Figure 2 As shown, the support frame 1 includes a square frame 11 and a middle beam 12 installed in the middle of the square frame 11. The middle beam 12 simultaneously supports the close sides of the conveyor belts 21 of the two conveyor belt mechanisms 2.

[0032] In this embodiment, as Figure 1 As shown, the length of the support frame 1 is less than the length of the cross-cutting blade 101.

[0033] This satisfies the requirement for half-width harvesting.

[0034] Example 2

[0035] like Figure 1 As shown, a slashing machine includes the slashing machine horizontal conveying device described in Embodiment 1.

[0036] In this embodiment, preferably, as Figure 1As shown, the harvester also includes a longitudinal cutting blade 102 for cutting the lateral branches of crops.

[0037] This prevents the cut crop stalks from becoming entangled with unharvested crop branches on the sides and falling over, thus enabling a better harvest.

[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
