Description

Technical Field

[0001] The invention relates to the technical field of animal husbandry machinery, in particular to a mowing and slicing machine. Background Art

[0002] There are many types of forage grass in my country, and some of them can be mowed many times a year. The best harvest period is about 10-15 days each time. The time is tight and the task is heavy, and there is a rush to harvest. Advanced forage harvesting machinery is an important guarantee for improving the efficiency of forage harvesting and improving the quality of forage. Using machinery to harvest forage grass in a timely manner not only retains the nutrients and dry matter of the original forage grass, but also greatly increases labor productivity, reduces forage loss, and increases the economic benefits brought by forage production. The northwest region is vast and sparsely populated. Although it has rich grassland resources, accounting for 64.1% of the country's grasslands, the season for forage harvesting is mostly rainy season. Especially for high-quality forage grass like alfalfa, the drying speed determines the quality of forage grass. The harvested forage grass relies on natural drying in the field. Not only is the long drying time easy to cause the forage grass to rot and deteriorate, but it is also not conducive to the maintenance of forage nutrients and dry matter. Therefore, this also puts forward multi-functional requirements for forage harvesters, and the drying speed of forage grass needs to be accelerated. my country's pasture planting environment is harsh, the terrain is undulating, and most of the local pasture harvesting equipment is backward, the cutting height control is unstable, and the mower is easy to destroy the soil structure of the surface pasture when mowing low, exposing the sand, which makes the originally weak grassland ecosystem suffer greater damage. The present invention is mainly aimed at complex terrain, the grass is not easy to dry after mowing, and the grass rake is needed to cooperate with the operation. A mowing and adjusting strip collection machine is invented to adapt to the terrain, control the cutting height, and solve the problem of slow drying and difficult storage of pasture.

[0048] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments cannot be described one by one here, but the embodiments of the present invention are not therefore limited to the following embodiments.

[0049] Combination Figure 1 and Figure 2 As shown, according to one embodiment of the present invention, a mowing and modulating strip collecting machine of the present invention comprises: a support unit 11, a hydraulic unit 12, a transmission unit 13, a mowing unit 14, a modulation unit 15 and a strip collecting unit 16 arranged on the support unit 11. In this embodiment, the mowing unit 14 and the modulation unit 15 are respectively connected to the transmission unit 13, and the modulation unit 15 is located between the mowing unit 14 and the strip collecting unit 16.

[0050] According to the present invention, through the above-mentioned mowing and modulation and collection machine, as it is towed forward, through the harvesting action of the mowing unit 14, the modulation unit 15 receives the grass harvested and transported by the mowing unit 14, squeezes and modulates it, and then inputs it into the collection unit 16, and the collection unit 16 gathers and collects the grass and then sends it out, thereby realizing the automated flow operation from harvesting to packaging of grass, and greatly improving the efficiency of grass harvesting.

[0051] Combination Figure 1 and Figure 2 As shown, according to an embodiment of the present invention, the support unit 11 includes: a traction mechanism 111, a main beam mechanism 112, a frame 113 and a traveling mechanism 114. In this embodiment, the traction mechanism 111, the frame 113 and the traveling mechanism 114 are respectively connected to the main beam mechanism 112. In this embodiment, along the horizontal direction, the traction mechanism 111, the frame 113 and the traveling mechanism 114 are arranged in sequence.

[0052] Combination Figure 1 and Figure 2 As shown, according to one embodiment of the present invention, the main beam mechanism 112 is located above the traction mechanism 111 , the frame 113 and the walking mechanism 114 .

[0053] Through the above arrangement, the main beam mechanism 112 is arranged above the traction mechanism 111, the frame 113 and the walking mechanism 114, which is conducive to forming a larger installation space below the supporting unit 11, which is conducive to the installation of other mechanisms and ensures the reasonable distribution of positions between other mechanisms, as well as beneficial effects such as power transmission.

[0054] Combination Figure 1 and Figure 2 As shown, according to one embodiment of the present invention, the main beam mechanism 112 includes: a traction main beam 1121 and a suspension main beam 1122 hinged to the traction main beam 1121. In this embodiment, the traction mechanism 111 is arranged at one end of the traction main beam 1121 away from the suspension main beam 1122; the walking mechanism 114 is arranged at one end of the suspension main beam 1122 away from the traction main beam 1121; and a shock absorber 1123 is arranged between the frame 113 and the suspension main beam 1122. In this embodiment, the upper part of the frame 113 is connected to the suspension main beam 1122 through the frame suspension rod 113a, one end of the shock absorber 1123 is connected to the rear end of the suspension main beam 1122 (i.e., the end away from the traction main beam 1121), and the other end is connected to the lower tail end of the frame 113.

[0055] Combination Figure 1 and Figure 2 As shown, according to one embodiment of the present invention, the mowing unit 14 , the modulation unit 15 and the strip collecting unit 16 are arranged on the frame 113 .

[0056] Through the above-mentioned arrangement, the inclination setting of the shock-absorbing device 1123 is realized, so that when the mower and strip collecting machine of the present invention moves forward and the frame 113 is obstructed in front, the shock-absorbing device 1123 can better bridge the buffering effect, which is beneficial to ensuring the stable operation of the entire frame 113 and the mechanism installed on the frame 113.

[0057] Combination Figure 1 and Figure 2 As shown, according to an embodiment of the present invention, the hydraulic unit 12 includes: a hydraulic oil circuit 121, a traction adjustment cylinder 122 and a travel adjustment cylinder 123 connected to the hydraulic oil circuit 121. In this embodiment, the opposite ends of the traction adjustment cylinder 122 are respectively hinged to the traction main beam 1121 and the suspension main beam 1122, and are used to adjust the inclination angle of the traction main beam 1121 relative to the suspension main beam 1122 in the horizontal direction.

[0058] Through the above arrangement, the traction main beam 1121 can be swung in the horizontal direction through the action of the traction adjustment cylinder 122, so that the entire mowing and modulation collection machine and the front end traction are in the same straight line (see Figure 1), or the entire mower trimmer is parallel to the front traction on one side of the front traction (see Figure 2 ).

[0059] In this embodiment, opposite ends of the travel adjustment cylinder 123 are respectively hinged to the suspension main beam 1122 and the travel mechanism 114, so as to adjust the height of the suspension main beam 1122 relative to the travel mechanism 114 in the vertical direction.

[0060] Through the above arrangement, under the action of the travel adjustment cylinder 123, the extension and retraction of the travel adjustment cylinder can be controlled through the hydraulic oil circuit to control the height of the frame and thus the height of the mowing unit, so that the height of the grass stubble can be adjusted.

[0061] Combination Figure 1 and Figure 2 As shown, according to an embodiment of the present invention, the modulation unit 15 comprises: a rotatable upper glue roller 151 and a lower glue roller 152. In this embodiment, the upper glue roller 151 and the lower glue roller 152 rotate in opposite directions.

[0062] Combination Figure 1 and Figure 2 As shown, according to one embodiment of the present invention, the relative spacing between the upper rubber roller 151 and the lower rubber roller 152 is adjustable. In this embodiment, a spacing adjustment structure for adjusting the spacing between the upper rubber roller 151 and the lower rubber roller 152 is installed between them, so that the spacing between the upper rubber roller 151 and the lower rubber roller 152 can be flexibly adjusted, thereby achieving the modulation and processing of various forages.

In this embodiment, a plurality of rotating devices 141 are arranged side by side at intervals along the length direction of the supporting device 142. In this embodiment, the rotation directions of adjacent rotating devices 141 are opposite.

[0064] Through the above configuration, by providing multiple rotating devices 141, the harvesting device of the present invention can perform a wide range of harvesting operations, greatly improving the operating efficiency of the present invention. In addition, by setting the rotation directions of adjacent rotating devices 141 to be opposite, the adjacent rotating devices 141 can, after cutting the grass, work together to close the dumped grass and transfer it to the rear modulation unit, which is beneficial to the subsequent bundling and packaging of the grass.

[0065] Combination Figure 3 and Figure 4As shown, according to one embodiment of the present invention, the rotating device 141 includes: a rotating support 1411, a cutting mechanism 1412 installed at the edge of the rotating support 1411, and a weeding structure 1413 installed on the rotating support 1411 and located on one side of the cutting mechanism 1412. In this embodiment, along the vertical direction, the weeding structure 1413 protrudes from the upper side of the rotating support 11.

[0066] According to the present invention, by setting the cutting mechanism 1412, the rotating support 1411 drives the cutting mechanism 1412 to move and cut the grass and the like during the rotation process. After the grass is cut, in the process of the rotating unit moving forward, the grass-moving structure 1413 limits the fallen grass, and then the grass-moving structure 1413 transports the fallen grass to the subsequent modulation unit as the rotating support 1411 rotates, so that the present invention achieves the dual effects of harvesting and recycling, greatly improving the harvesting efficiency of the present invention, and has a simple structure, stable operation, and low cost.

[0067] According to one embodiment of the present invention, the grass-clearing structure 1413 is a vertical plate structure arranged along the vertical direction.

[0068] According to another embodiment of the present invention, the vertical plate structure of the grass-clearing structure 1413 can be set as a telescopic plate-like structure. The grass-clearing structure 1413 has a plurality of plate-like components that can slide relative to each other, and a sliding connection is achieved by nesting or setting a sliding guide rail, and a locking member is set on the plate-like component to fix the relative position between adjacent plate-like components. Through the above-mentioned setting, its structure is simple, and the protruding height of the grass-clearing structure 1413 in the vertical direction can be flexibly adjusted, so that the grass-clearing structure 1413 of the present invention can be used for the recovery of different types of forage grass, thereby improving the applicability of the present invention.

[0069] Combination Figure 3 and Figure 4 As shown, according to one embodiment of the present invention, the weed-pulling structure 1413 further includes: an auxiliary plate structure 1413a. In this embodiment, one side of the auxiliary plate structure 1413a is fixedly connected to the side of the vertical plate structure 1413a away from the rotating support 1411, and the other side thereof extends obliquely toward the rotating support 1411. In this embodiment, the auxiliary plate structure 1413a is located on the side of the weed-pulling structure 1413 away from the cutting mechanism 1412.

[0070] Combination Figure 3 and Figure 4As shown, according to one embodiment of the present invention, the cutting mechanism 1412 includes: a mounting seat 1412a fixedly connected to the rotating support 1411, and a blade 1412b connected to the mounting seat 1412a.

[0071] According to the present invention, the blade 1412b and the mounting seat 1412a are configured to be detachable. In this way, the worn blade can be replaced after a long period of work, thereby ensuring the harvesting efficiency of the present invention. In addition, the blade and the mounting seat are configured to be rotatably connected, so that the blade can be automatically thrown out during the rotation of the rotating support 1411. In this way, when the blade encounters an obstacle that cannot be cut, it will automatically retract under resistance, thereby effectively avoiding wear or damage to the blade when encountering an obstacle, and effectively increasing the service life of the blade.

[0072] Combination Figure 3 and Figure 4 As shown, according to one embodiment of the present invention, a plurality of rotating devices 141 rotate synchronously, and the cutting mechanisms 1412 of adjacent rotating devices 141 are staggered. Through the above arrangement, the cutting mechanisms 1412 of adjacent rotating devices 141 are staggered, which effectively avoids interference or collision between the cutting mechanisms 1412 when different rotating devices 141 are working, thereby ensuring the stable operation of the entire harvesting process.

[0073] Combination Figure 1 and Figure 2 As shown, according to an embodiment of the present invention, the transmission unit 13 includes: a primary speed change transmission box 131 for connecting with a power source, a secondary speed change transmission box 132 for driving the mowing unit 14, a transmission shaft 133 for connecting the primary speed change transmission box 131 and the secondary speed change transmission box 132, a direction changing gear box 134, a first transmission member 135 for connecting the secondary speed change transmission box 132 and the modulation unit 15, and a second transmission member 136 and a third transmission member 137 for connecting the direction changing gear box 134 and the modulation unit 15.
