Description

Technical Field

[0001] The invention relates to the technical field of agricultural harvesting machinery, in particular to equipment for harvesting both highland barley and grain in Tibetan areas. Background Art

[0002] As one of the main crops in Tibetan areas, highland barley occupies an extremely important position in the local social, economic and cultural life. It not only provides an important source of food for the plateau area, but also its grains are rich in beneficial ingredients such as β-glucan and have high nutritional value. It is an important part of the daily diet of the Tibetan people and is often used to make tsampa and brew wine. At the same time, highland barley straw is also a high-quality feed resource. For Tibetan areas with developed animal husbandry, it provides necessary nutrition for livestock and helps to improve the production efficiency of animal husbandry. Therefore, harvesting highland barley as both food and grass can not only make full use of biological resources, but also promote sustainable agricultural development, ensure food security, and enhance the self-supply capacity of Tibetan areas. It is of great significance to maintain ecological balance and promote local economic development.

[0003] The applicant's prior applications CN117204202A and CN117084067A provide a mechanism that can horizontally aggregate and bundle highland barley. This mechanism can only obtain highland barley crops in full, and it is necessary to pick up and thresh highland barley crops later, and the process is relatively complicated. In the prior art, CN107493806A discloses a harvesting device for harvesting highland barley spikes and stems. In this patent, the whole highland barley is first harvested, and then the highland barley is lifted and lifted to the rear side of the machine, and the lower part of the spike is broken and collected. The spike and the straw are stored in different storage compartments respectively. In the solution of this patent, on the one hand, its structure is relatively scattered and the layout is unreasonable, resulting in a large machine. On the other hand, it can only collect broken grass, and the subsequent use of broken grass is not as much as that of complete highland barley straw, and the spike collected by the machine needs to be threshed later, which will reduce production efficiency. Summary of the invention

[0004] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a Tibetan highland barley grain and forage harvesting equipment which has a reasonable layout, complete functions and can harvest highland barley grains and complete straw separately.

[0005] Technical solution: To achieve the above-mentioned purpose, the Tibetan highland barley grain and grass harvesting equipment of the present invention comprises a mobile body, on which a grain separation and harvesting mechanism, a conveying mechanism, a threshing mechanism and a seed cabin are installed; the conveying mechanism is connected to the threshing mechanism, and the highland barley grains threshed out of the threshing mechanism enter the seed cabin; the grain separation and harvesting mechanism comprises a plurality of grain separation units arranged laterally and an ear-grass separation mechanism, and there is a grain entry channel between adjacent grain separation units, and also comprises a cutting knife mechanism placed on the lower side of all the grain separation units;

[0006] The ear-grass separation mechanism includes a guiding mechanism placed above each of the grain-entering channels, and also includes an ear-cutting mechanism located below the rear sides of all the guiding mechanisms;

[0007] The guiding mechanism comprises a pair of rollers, each of which has a central axis and a rubber layer covering the outer side of the central axis, the rollers are at least partially bent, and the gap between the two rollers gradually narrows from wide; the rollers are arranged with a low front and a high rear, and the outer surface of the rollers has a spiral pattern;

[0008] A baling device is installed on the rear side of the cutting knife mechanism, and the baling device is located below the ear cutting mechanism.

[0009] With the above structure, during the harvesting process of the grain and grass harvesting equipment, as the equipment moves forward, the lower half of the highland barley crop continuously enters the entry channel between the grain-dividing units. For the highland barley crop entering the entry channel, the stalk between the root and the ear enters between the two rollers of the guide mechanism and is subjected to the friction of the rotating rollers. The rollers apply an upward friction force to the highland barley crop, and the spiral pattern on the rollers causes the stalk of the highland barley to move backward. Since the rollers are lower in front and higher in the back, the highland barley can be straightened and the ear of the highland barley can be kept on the rollers. When the ear reaches the position of the ear-cutting mechanism, the ear-cutting mechanism cuts off the ear, causing the ear to enter the conveying mechanism, and the conveying mechanism sends the ear to the threshing mechanism for threshing. The grains threshed by the threshing mechanism enter the seed cabin. In the above process, the effect of the spiral pattern can cause the stalk of the highland barley to move backward faster and reach the ear-cutting mechanism first, so that the ear of the highland barley crop is cut off before the root.

[0010] After the ear cutting mechanism cuts off the ear, the root of the remaining stalk is cut off by the cutting knife mechanism, and the baling device bales the stalk.

[0011] Furthermore, the roller body has a first straight segment, a second straight segment, and a third straight segment arranged in sequence front to back, and also has a first curved segment between the first straight segment and the second straight segment, and a second curved segment between the second straight segment and the third straight segment;

[0012] The gap between the two first straight segments corresponding to the two roller bodies belonging to the same guiding mechanism gradually narrows from wide, the corresponding two second straight segments are parallel to each other, the corresponding third straight segments are parallel to each other, and the inclination of the third straight segment is smaller than the inclination of the second straight segment, and the third straight segment is located above the ear cutting mechanism.

[0013] The roller body has a continuous central axis, and the shaft segments corresponding to the first straight segment, the second straight segment and the third straight segment are all straight axes, and the shaft segments corresponding to the first curved segment and the second curved segment are spiral, so that the rigidity of the straight segment can be maintained and the multi-directional bendability of the curved segment can be maintained.

[0014] Furthermore, a bracket is fixed on the grass-dividing unit, and the bracket has a plurality of branch connection parts, and the two ends of the first curved section and the two ends of the second curved section are both connected with the branch connection parts; the branch connection parts are rotatably connected to the central axis of the connecting parts; and the two ends of the roller body are respectively connected with bearing seats. With the above structure, the extension direction of the roller body can be effectively maintained.

[0015] Furthermore, the bearing seats at the tail of all the rollers are installed on the same plate; the tail of each roller is also connected to the transition shaft at the back of the plate through a belt mechanism; the two transition shafts corresponding to the two rollers of the same guide mechanism are connected through a synchronous gear, and a first bevel gear is fixed on the transition shaft corresponding to one of the rollers, and a left and right horizontal axis is also installed on the back of the plate, and a second bevel gear meshing with each of the first bevel gears is fixed on the horizontal axis, and the horizontal axis is connected to a power source. In this way, all rollers can be driven to operate synchronously at the same time, and the two rollers of the same guide mechanism rotate in opposite directions at the same speed.

[0016] Furthermore, the conveying mechanism comprises a transverse conveying trough, an augers is installed in the conveying trough, and a conveying channel connected to the threshing mechanism is installed in the middle of the rear side of the conveying trough.

[0017] Furthermore, the bundling device includes a transverse conveying mechanism and a bundling mechanism located at an end of the transverse conveying mechanism.

[0018] Furthermore, a storage channel is provided at the rear side of the bundling mechanism, and a conveying mechanism is provided at the bottom of the storage channel. The barley stalks can be stored in bundles in the storage channel.

[0019] Beneficial effects: The Tibetan highland barley grain and grass harvesting equipment of the present invention has the following beneficial effects:

[0020] (1) The Tibetan highland barley grain and grass combined harvesting equipment of the present invention has a reasonable layout, a compact structure and a small size, and a reasonable method for handling highland barley crops. Through the ear cutting mechanism and the conveying mechanism arranged on the top and the baling device arranged on the bottom, the ear and the stalk can be effectively separated, and threshing and baling are performed separately, so as to achieve grain and grass combined harvesting. The stalks after baling are complete and neatly bundled, and have more uses.

[0021] (2) In the roller body, the first straight section can effectively gather the stalks of the barley crop, the second straight section can straighten the stalks of the barley crop, and the third straight section is used to keep the ear on the ear cutting mechanism, which can effectively gather, straighten the stalks and assist in ear cutting.

DETAILED DESCRIPTION

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] like Figure 1 The Tibetan highland barley grain and forage harvesting equipment shown includes a mobile body 1, on which are installed a grain separation and harvesting mechanism 2, a conveying mechanism 3, a threshing mechanism 4 and a seed cabin 5; the conveying mechanism 3 is connected to the threshing mechanism 4, and the highland barley grains threshed out of the threshing mechanism 4 enter the seed cabin 5.

[0032] like Figure 2-Figure 4As shown, the grain-separating and harvesting mechanism 2 includes a plurality of grain-separating units 21 and an ear-grass separation mechanism arranged transversely, a grain-entry channel is provided between adjacent grain-separating units 21, and also includes a cutting knife mechanism 22 disposed at the lower side of all the grain-separating units 21. The ear-grass separation mechanism includes a guiding mechanism 23 disposed above each of the grain-entry channels, and also includes an ear-cutting mechanism 24 disposed at the lower rear side of all the guiding mechanisms 23.

[0033] The guiding mechanism 23 includes a pair of rollers 231. Figure 6 As shown, the roller body 231 has a central axis 23a and a rubber layer 23b covering the outer side of the central axis. The roller body 231 is at least partially bent, and the gap between the two roller bodies 231 gradually narrows from wide; the roller body 231 is low in front and high in the back, and the outer surface of the roller body 231 has spiral patterns.

[0034] A baling device 6 is installed at the rear side of the cutting knife mechanism 22 , and the baling device 6 is located below the ear cutting mechanism 24 .

[0035] With the above structure, during the harvesting process of the grain and grass harvesting equipment, as the equipment moves forward, the lower half of the barley crop continuously enters the grain entry channel between the grain separation units 21. For the barley crop entering the grain entry channel, the stalk between the root and the ear enters between the two roller bodies 231 of the guide mechanism 23 and is subjected to the friction of the rotating roller bodies 231. The roller bodies 231 apply an upward friction force to the barley crop. The spiral pattern on the roller bodies 231 causes the stalk of the barley to move backward. Since the roller bodies 231 are lower in front and higher in the back, the barley can be straightened and the ear of the barley can be kept on the roller bodies 231. When the ear reaches the position of the ear cutting mechanism 24, the ear cutting mechanism 24 cuts off the ear, allowing the ear to enter the conveying mechanism 3. The conveying mechanism 3 sends the ear to the threshing mechanism 4 for threshing, and the grains threshed by the threshing mechanism 4 enter the seed cabin 5. In the above process, the spiral pattern can make the stalk of highland barley move backward faster and reach the ear cutting mechanism 24 first, so that the ear of the highland barley crop is cut off before the root.

[0036] After the ear cutting mechanism 24 cuts off the ear, the root of the remaining stalk is cut off by the cutting knife mechanism 22, and the baling device 6 bales the stalk.

[0037] The Tibetan highland barley grain and grass combined harvesting equipment of the present invention has a reasonable layout, a compact structure and a small volume, and a reasonable method for handling highland barley crops. Through the ear cutting mechanism 24 and the conveying mechanism 3 arranged on the top and the baling device 6 arranged on the bottom, the ear and the stalk can be effectively separated, and threshing and baling are performed respectively, so as to realize the grain and grass combined harvesting. The stalks after baling are complete and neatly bundled, and have more uses.

[0038] Preferably, if Figure 5As shown, the roller body 231 has a first straight segment 2a, a second straight segment 2b, and a third straight segment 2c arranged in sequence front to back, and also has a first curved segment 2d located between the first straight segment 2a and the second straight segment 2b, and a second curved segment 2e located between the second straight segment 2b and the third straight segment 2c;

[0039] The gap between the two first straight segments 2a corresponding to the two roller bodies 231 belonging to the same guiding mechanism 23 gradually narrows from wide, the corresponding two second straight segments 2b are parallel to each other, and the corresponding third straight segments 2c are parallel to each other, and the inclination of the third straight segment 2c is smaller than the inclination of the second straight segment 2b, and the third straight segment 2c is located above the ear cutting mechanism 24.

[0040] With the above structure, the first straight section 2a can effectively gather the stalks of the barley crop, the second straight section 2b can straighten the stalks of the barley crop, and the third straight section 2c is used to keep the ear on the ear cutting mechanism 24, which can effectively gather, straighten the stalks and assist in ear cutting.

[0041] The roller body 231 has a continuous central axis 23a, and the axis segments of the central axis 23a corresponding to the first straight segment 2a, the second straight segment 2b and the third straight segment 2c are all straight axes, and the axis segments corresponding to the first curved segment 2d and the second curved segment 2e are spiral, so as to maintain the rigidity of the straight segment and the multi-directional bendability of the curved segment.

With the above structure, the extension direction of the roller body 231 can be effectively maintained.
