Description

Technical Field

[0001] The invention belongs to the technical field of straw harvesting equipment and relates to a straw harvesting equipment, in particular to a large-area straw harvesting and processing equipment based on feed processing. Background Art

[0002] During the growth of livestock, the quality of feed plays a decisive role in their growth. Therefore, people usually process various feed varieties for livestock to achieve the goal of livestock growth to be stronger and healthier. Silage is a crop specially planted to solve the problem of livestock feeding. After processing, it can have the advantages of sour smell, soft and juicy, good palatability, rich nutrition, and conducive to long-term preservation. It is one of the most common feed varieties on the market.

[0003] When silage is processed, it needs to be crushed, and the crushing process is usually carried out by using a harvester to roughly crush the crops when harvesting them in the fields. The crushed crops are either sent directly to the processing plant for processing or simply compacted and packaged and then sent to the processing plant for processing. Under closed and oxygen-deficient conditions, the fermentation of anaerobic lactic acid bacteria inhibits the reproduction of various bacteria, and a finished silage product is obtained.

[0004] At present, the most common raw material crop for silage is corn (referring to the whole corn, including fruit, leaves, stalks, and skin). Under the conditions of large-scale farmland cultivation, the growth of corn varies due to various growth conditions such as water volume, fertilizer volume, and soil, resulting in local corn becoming too old, too green, or withered. These old and withered corns and the roots of corn stalks do not have higher utilization value in terms of nutritional value and palatability, but will affect the preservation effect of feed. In addition to corn, the same situation also occurs when planting crops such as soybeans and sorghum.

[0005] However, when harvesting, the harvester is not a professional crushing equipment. Therefore, the crushing effect of corn that is too old or withered or its roots are hardened due to poor crushing effect. These crops with poor crushing degree not only have low utilization value, but also affect their palatability after processing, which greatly affects the quality of silage. Summary of the invention

[0006] The purpose of the present invention is to provide a large-area straw harvesting and processing equipment for feed processing to solve the problem in the prior art that silage raw material harvesters are unable to separate old, withered corn stalks and the roots of corn stalks during harvesting, thereby reducing the quality of subsequently processed silage feed products.

[0050] Please refer again Figure 1 As shown, a motor 20 and a differential 21 are fixed by screws at the platform outside the collecting bin 1, the motor 20 and the differential 21 are mutually driven via a belt, the output end of the motor 20 is directly driven to the central axis of the roller 3 via a belt, the rollers 3 are mutually driven via belts, and the output end of the differential 21 is directly driven to the drive shaft 5 via a belt.

[0051] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation mode of the present invention in the actual process is described in detail below:

[0052] Operators move the harvester into the farmland and freely choose different harvesting plans according to the growth of silage crops in the farmland.

[0053] When the operator drives the harvester and the cooperating material transport vehicle to the farmland to harvest the silage crops, the harvester is used to harvest the silage crops into the collecting bin inside the harvester (if the harvester has its own storage bin, the collecting bin is integrated into the storage bin; if it does not have its own storage bin, the collecting bin is integrated into the bucket of the cooperating material transport vehicle), and then the silage crops roughly crushed by the harvester are thrown into the partition block 8 below the first chamber through the guiding effect of the guide plate 4;

[0054] Before this, if the operator observes that the silage crops in the farmland are growing well and suitable for direct harvesting, the operator can directly start the electric push rod 18 by operating the switch inside the cab, and use the electric push rod 18 to apply an upward force to the linkage block 17, so that it drives the round rod 16 to move upward. Since the round rod 16 and the moving block 11 are separated at both ends of the connecting rod 14, the moving block 11 moves downward when the round rod 16 moves upward based on the seesaw principle. Since the moving block 11 is connected to the limit plate 10 through the connecting plate 101, the limit plate 10 moves downward at the bottom of the limit block 9, so that the limit plate 10 is separated from the limit block 9;

[0055] At this time, since the limiting plate 10 is separated from the limiting block 9, the corresponding limiting block 9 and the dividing block 8 are connected to the same long rod 7, and the long rod 7 is rotatably connected to the rotating belt 6, the dividing block 8 is affected by its own gravity and droops and is in a vertical state, which results in gaps between the dividing blocks 8 at this time, thereby achieving the effect of screening and separation; the screening object at this time is the root of the silage crop straw, and this part that is hardened and difficult to be crushed by the harvester is left on the dividing block 8, and then transferred to the inside of the second chamber under the cooperation of the transmission shaft 5 and the rotating belt 6; and the other part, which is tender and easy to be crushed by the harvester because of the high moisture content of the crop, falls from the gap between the dividing blocks 8 to the inside of the first chamber, thereby achieving the purpose of removing the straw roots that have little utilization value from the inside.

[0056] Before this, if the operator observes that the silage crops in the farmland are partially too old or withered, then the operator uses the electric push rod 18 switch inside the cab to send a command to the electric push rod 18 again, and uses the same mechanical action mechanism to move the limit plate 10 upward at the bottom of the limit block 9, so that the limit plate 10 fits the limit block 9 and the limit block 9 is in a parallel state;

[0057] It is worth noting here that: since the bottom of the limit block 9 is provided with an inclined surface, and the corners of the limit block 9 are set as rounded corners, all the limit blocks 9 are rotated 90° toward the side away from the second chamber under the action of the limit plate 10, thereby achieving the purpose of all the limit blocks 9 located on the limit plate 10 being in a parallel state;

[0058] In addition, if Figure 6 As shown in the partial enlarged view, since the partition block 8 rotates continuously with the rotating belt 6, the partition block 8 will be constantly kept in a parallel state under the forced action of the end of the limiting plate 10;

[0059] At this time, since the limit block 9 and the dividing block 8 are on the same side of the long rod 7, the dividing block 8 is also in a parallel state, so that the gap between the dividing blocks 8 is closed, and the screening and separation function cannot be achieved. After the harvester sends the silage crop straw that is too old or withered into the upper part of the dividing block 8, it can be directly transported to the inside of the second chamber under the action of the transmission shaft 5 and the rotating belt 6, thereby achieving the purpose of separating the silage crops with good growth from the silage crops that are too old or withered.

[0060] By using the harvesting and processing equipment in conjunction with a harvester, the roots of silage crops with good growth can be separated from those with low utilization value when harvesting them, and the silage crops that are too old or withered can be separated and transported when harvesting them, and stored together with the roots of low value. The product quality of the silage can be improved during the subsequent processing of the silage crop raw materials.

[0061] Embodiment 2:

[0062] The collecting bin 1 is rotatably connected to the position corresponding to the feeding port 2 with symmetrically arranged rollers 3; straight rods 301 are evenly distributed and fixed on the rollers 3; the straight rods 301 are rotatably connected to the swinging rods 302, and the straight rods 301 and the swinging rods 302 are alternately arranged on the two rollers 3, so as to break up the compressed and packaged silage raw materials and facilitate their subsequent separation processing.

[0063] At the same time, some silage raw materials require the processing plant to dispatch workers to the farmers' fields to harvest unnecessary straw. At this time, these silage raw materials will be compressed and baled for transportation. When the collecting bin 1 is installed in the warehouse before processing, the centrifugal force generated by the rotation of the roller 3 is used in conjunction with the straight rod 301 and the swing rod 302, so that the swing rod 302 can use the inertia force when rotating to completely break up the compressed and packaged silage raw materials, and then use the partition block 8 to separate and screen them, so as to achieve a better separation effect and improve the quality of the silage product.

[0064] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
