[0002] Global atmospheric pollution has posed a serious threat to human survival and reproduction, and the environmental awareness of the world's people has been forced to become stronger year by year! As the world's most populous developing agricultural country, China has also been deeply troubled in recent years. And my country's traditional straw burning is one of the main factors of staged air pollution. Therefore, in recent years, the state has formulated a series of prevention and control and guidance policies, so the treatment of straw, especially recycling and reuse, has also set off a new wave of initial exploration and practice. Projects such as straw burning for power generation, making carbon rods, making boards, fermenting alcohol, and biofertilizer have begun to take shape. However, several major factors have always been bottlenecks: one is that the soil content in the straw is extremely high. Therefore, it is easy to rot and difficult to preserve, so it is difficult to reuse; the other is that the seasonal land preparation time is very short. If the straw cannot be recycled in time, it will inevitably affect the progress of land preparation. If the farming is not guaranteed, it will greatly affect the yield of the next crop. The third is that there are few varieties of picking and baling machines, the number is scarce, the performance is backward, there are too many operating links, the efficiency is low, the recycled straw has a high soil content and serious damage to the soil. Therefore, the application rate of straw bales is very low. As a result, most power plants and other corn straw utilization projects have serious shortages or even closures due to the lack of fuel sources and high soil cleaning and reprocessing costs, creating a vicious cycle.

[0003] Therefore, there is an urgent need in the art to provide a device that can complete all operations of straw recovery, including straw harvesting and concentration, chopping and kneading, pre-pressing and pre-storage, secondary bundling, and centralized unloading. Summary of the invention

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the present invention is described in detail with reference to schematic diagrams. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0023] Figure 1It is a simplified schematic diagram of a high-speed self-propelled mower-pressing combined series baler according to an embodiment of the present invention. As shown in the figure, the high-speed self-propelled mower-pressing combined series baler according to the present invention comprises a harvesting concentration system 1, a chopping and kneading system 2, a pre-pressing and pre-storage system 3, a bundling system 4 and a centralized unloading system. The chopping and kneading system 2 and the pre-pressing and pre-storage system 3 are arranged between the harvesting concentration system 1 and the bundling system 4. With the high-speed self-propelled mower-pressing combined series baler according to the present invention, during the straw recycling operation, the operations of straw harvesting concentration, chopping and kneading, pre-pressing and pre-storage, bundling, centralized unloading and the like are completed at one time.

[0024] The following is an introduction to the harvesting concentration system 1.

[0025] like Figure 1 As shown, the harvesting and concentrating system 1 includes a reel 11, an auger 13 and a header 15. The arrangement of these components can adopt structures well known in the art, so they are not described in detail.

[0026] The cutting table 15 and the cutting knife it has should highlight the low cutting stubble and have good profiling and grabbing functions. The reel design should highlight the grabbing ability. The batch feeding function can ensure that the straw is fed evenly. The settings of these components can adopt those known in the art, so they will not be repeated here.

[0027] Figure 1 The driving system in the harvesting and concentrating system 1 is also shown, such as a driving motor 12 and a pulley 14. The driving motor 12 drives the reel 11 and the auger 13 to rotate. The arrangement of these components is well known, so they will not be described in detail.

[0028] In one embodiment, in order to achieve better results, the cutting platform 15 includes a slow roller cutter and a fast roller cutter that rotate in opposite directions in cooperation with each other, and the speed of the fast roller cutter is greater than the speed of the slow roller cutter. The roller cutter can be installed in a conventional structure, so it is not repeated here. This structure is particularly suitable for cutting and picking hard straw crops such as corn, and can realize the grabbing, cutting and conveying thereof. The slow roller cutter and / or the fast roller cutter have a webbed handle, and the speed difference between the two can be adjusted according to the strength and amount of the straw. The webbed handle can generate a flowing vacuum, thereby grabbing, cutting, chopping and vacuum adsorption, tangential dust removal, etc. of the straw. The cutting platform 15 can also include a safety clutch for cutting off the power of the slow roller cutter and the fast roller cutter, so that they can be prohibited from rotating when necessary, such as when a fault occurs. The slow roller cutter and the fast roller cutter can be provided with a gear drive device to drive them to rotate.

[0029] The following is an introduction to the chopping and kneading system 2.

[0030] The chopping and kneading system 2 comprises a feeding pair of roller cutters consisting of an upper roller cutter 21 and a lower roller cutter 25 and a downstream kneading mechanism.

[0031] In one embodiment, the feeding roller cutter of the chopping and kneading system chop the straw as required. For example, the upper roller cutter 21 can be a spiral roller cutter, and the lower roller cutter 25 can be a round roller cutter. The speed difference between the upper roller cutter 21 and the lower roller cutter 25 can be about 50%. The blade on the lower roller cutter 25 can be detachable. This makes replacement convenient.

[0032] In one embodiment, the kneading mechanism is used to sort and convey the material, including: a side kneading device, which includes a side kneading roller 22 and a first forward conveying roller 26 cooperating therewith; and a centripetal kneading device, which includes a centripetal kneading roller 23 and a second forward conveying roller 27 cooperating therewith, and the herringbone teeth of the side kneading roller 22 and the centripetal kneading roller 23 are arranged in opposite directions. The specific direction can be set as needed. In this way, the side kneading device sorts the straw from the middle to the two sides, and the centripetal kneading device sorts the straw from the two sides to the middle, forming a more standardized built-in straw strip.

[0033] The side kneading roller 22 may have herringbone teeth, and the first forward conveying roller 26 may have straight teeth. The speed difference between the side kneading roller 22 and the first forward conveying roller 26 may be 30%-50%, and the speed difference may be adjusted. The centripetal kneading roller 23 may have herringbone teeth, and the second forward conveying roller 27 may have straight teeth. The speed difference between the centripetal kneading roller 23 and the second forward conveying roller 27 may be 30%-50%, and the speed difference may be adjusted.

[0034] For the improvement of the existing technology, the chopping and kneading system 2 and the pre-pressing and pre-storage system 3 are both important components for forming standardized and high-density straw strips, and are also the main difference from the existing balers in the world.

[0035] like Figure 1 As shown, a driving device is also shown, such as a driving motor 24, which drives the upper roller cutter 21, the side kneading roller 22, and the centripetal kneading roller 23 to rotate. Of course, other driving structures can also be imagined.

[0036] The pre-pressurization and pre-storage system 3 is introduced below.

[0037] The pre-pressing and pre-storage system 3 is located downstream of the kneading mechanism, and includes multiple pairs of pressing rollers and a pair of pressing and feeding rollers downstream thereof. Each pair of pressing rollers includes an upper roller and a lower roller. Downstream of the pressing and feeding rollers is the bundling system 4.

[0038] For example, the first upper roller 31 and the second upper roller 32 shown in the figure can be floating pressing rollers. How to set the floating rollers is well known in the art, so it will not be described in detail. The first lower roller 35 and the second lower roller 36 can be conveying rollers, which are driven by a motor to drive the sprocket and the tensioning wheel. The upper roller and the lower roller can be spur rollers. In this way, by using the pre-pressing and pre-storage system 3, on the one hand, the built-in straw strips of the previous system are compacted step by step (with adjustable pressure) by using multiple upper and lower spur rollers, so that the density of the built-in straw strips is increased to facilitate subsequent high-speed baling and improve the baling density; on the other hand, the pre-storage function is realized, so that there is no need to stop the car when the bale is wrapped around the net.

[0039] Thanks to the whole-bale and pre-pressing system, it can ensure the standard bale shape, less deformed bales, high yield of straw crushing, small loss and easy loading, unloading and transportation.

[0040] like Figure 1 As shown, the compression feed roller pair includes an upper compression feed roller 34 and a lower input conveying roller 37. The upper compression feed roller 34 and the lower input conveying roller 37 are connected by a chain and rotate at a common speed.

[0041] Figure 1 Also shown is a drive device, such as a drive motor 33, which drives the pinch feed roller pair.

[0042] The bundling system 4 is described below.

[0043] In another embodiment, if Figure 1 As shown, the baling system 4 may include a conveying roller 47, a follower wheel 46, a driving wheel 42, and one or more tension wheels located in the path between the driving wheel 42 and the follower wheel 46, such as the first tension wheel 43, the second tension wheel 44, and the third tension wheel 45 shown in the figure, so that the pressure of the baling system on the straw group can be adjusted as needed. It should be understood that Figure 1 For illustration only, a plurality of follower wheels may be disposed on the path between the drive wheel 42 and the follower wheel 46 .

[0044] In another embodiment, the bundling system 4 is configured as a secondary bundling system, including an outer rolling mechanism for completing outer rolling and an inner rolling mechanism for completing inner rolling. In this way, the secondary bundling system is designed with a bundling mode of first outer rolling and then inner rolling, and utilizes the composite bundling principle to ensure high-speed, high-density and high-efficiency bundling, and the bundling density is adjustable within a certain range.

[0045] Figure 1 Also shown is a tying rope mechanism, for example, a net-feeding forming roller 41, which is used to wrap the bundled straw, which is well known in the art and will not be described in detail. The centralized unloading system can adopt a structure well known in the art and will not be described in detail.

[0046] The centralized unloading system can adopt a structure known in the art, which not only solves the problem of land crushing and cost consumption during the loading process, but also minimizes the impact of the straw recovery process on subsequent land preparation operations.

[0047] In order to highlight the key points of the present invention, the description of conventional structures in the baler is omitted, such as various transmission mechanisms, lubrication mechanisms, etc. In addition, the wheels and rollers can be interchanged.

[0048] In the present application, "downstream" is relative to the moving direction of the straw. One component is downstream of another component, which means that the material passes through the one component before passing through the other component.

[0049] The high-speed self-propelled cutter-presser series baler can of course also include an electronic control system and a hydraulic system. The electronic control system and the hydraulic system can make all major movements automatically completed, maximizing efficiency and reducing operator fatigue.

[0050] The high-speed self-propelled combined mower and baler series can be designed with a maximum practical operating speed, for example, 20 km / h; the bale diameter can be adjusted in the range of 1.2 m to 1.55 m; the number of net wrapping circles can be adjusted (for example, more than 2.2 circles); the cutting height can be actually set, for example, a minimum of 30-40 mm; the straw chopped length can be adjusted (for example, more than 5-6 cm).

[0051] The high-speed self-propelled baler of the present invention has at least the following advantages:

[0052] 1. The operations of harvesting, chopping, kneading, pre-pressing, pre-storing, bundling, especially secondary bundling, and centralized unloading of straw are completed at one time. Therefore, the straw does not fall to the ground and the bundling does not occupy land, which is its main feature. Since the three operation links of raking, picking up and bundling the straw are omitted, the straw does not come into contact with the ground during the operation process, so the soil and impurities in the straw can be reduced to the maximum extent. This is crucial for the sale and reuse of straw.

[0053] 2. The machine can be operated without stopping. This is another main feature of the machine. Compared with similar products, it can greatly save fuel, save time and increase efficiency.

[0054] 3. High-speed, efficient and high-density baling. The kneading system and pre-pressing and pre-storage system are designed. Since the straw is kneaded and pre-pressed in advance, and the baling and unloading can be done without stopping, the operating speed, baling speed, baling density and baling rate can be increased by more than 30% compared with the traditional type.

[0055] 4. Significantly reduce the occupation of manpower and machines, protect farming time, save costs and increase efficiency;

[0056] 5. The residual height is uniform and controllable. In addition, since the number of operations is four-in-one, it can not only greatly reduce the operating cost, but also minimize the number of times the baler operates on the land, thereby better protecting the cultivated land and laying a good foundation for the next land preparation;

[0057] 6. Due to the whole kneading and pre-pressing system, it can ensure that the bale shape is standardized, the number of deformed bales is small, the rate of finished straw crushing is high, the loss is small, and it is convenient for loading, unloading and transportation;

[0058] 7. The control system is advanced, easy and labor-saving to operate, thus reducing the fatigue of the tractor driver.

[0059] 8. The special cutting table designed according to the principle of chopping and flowing vacuum is very effective for thick stalks such as corn.

[0060] 9. The centralized unloading system not only solves the problem of crushing the cultivated land and cost consumption during the loading process, but also minimizes the impact of the straw recovery process on subsequent land preparation operations. This is especially important for the intense autumn land preparation work in the north.
