Description

Technical Field

[0001] The present application relates to the field of agricultural machinery, and is a miniature drum harvester for muddy fields in mountainous areas. Background Art

[0002] Farmland in mountainous and hilly areas often features complex terrain, with varying slopes and scattered, small plots. Traditional large harvesters, due to their bulk and weight, are difficult to maneuver in these complex terrains, prone to overturning and poor maneuverability, making them ill-suited for small-scale, scattered farmland operations. To overcome the limitations of traditional harvesters in mountainous areas, the market urgently needs a specialized small mountain harvester, specifically designed for these complex terrains, primarily for harvesting crops in small-scale farmland and mountain agriculture. This device can reach any mountainous field that large harvesters cannot. It is inexpensive, has a simple structure, and can directly thresh crops such as rice, wheat, and rapeseed. It is a valuable aid to farmers in achieving prosperity and a must-have small harvester for their homes. Field trials have proven its reliability and stability. Summary of the Invention

[0003] In light of this, the present application provides a miniature drum harvester for muddy fields in mountainous areas to address the problem of large equipment being unable to access small plots. The present application provides a miniature drum harvester for muddy fields in mountainous areas, comprising five major components: a harvesting table assembly with a straw pusher, a threshing unit assembly with an auger for discharging material, a drum wheel with a load-bearing bracket, a power source, and other auxiliary equipment (such as a transmission chain and a tray).

[0004] In summary, the present application includes at least the following beneficial technical effects: it can adapt to complex terrain, especially the ability to enter small plots for harvesting operations; it has efficient harvesting capabilities, and its compact shape only requires the price of an ordinary thresher to buy a multifunctional harvester. Due to its small size and roller wheels, you can put two wooden sticks at the height difference to push the harvester to move on it, and you can also move on very narrow field ridges. The rolling wheels will not affect the harvesting even if there is water in the field. The structure is welded, and if there is any problem, you can repair it at home. The main advantage is that the structure is simple, it can be flexibly used in the mountains, and it can also be driven on farmland with large height differences where roads are blocked.

[0013] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0014] The present application discloses a miniature drum harvester for muddy fields in mountainous areas and related equipment, which comprises a cutting table assembly with a support arm, a cutting table assembly with a straw pusher, a threshing device assembly with an auger discharger, a drum wheel with a load-bearing bracket, a power source and other auxiliary equipment (transmission chain, tray, etc.). In view of the defects of the existing technology, the present invention realizes the harvesting operation of fallen rice and small plots of rice through the above-mentioned mechanical combination; the threshing device realizes the functions of threshing, selecting, and crushing rice straw; the matching auger discharge port can discharge materials quickly, and the roller wheel can adapt to complex terrain, especially the ability to enter small plots for harvesting operations; this equipment has efficient harvesting capabilities, and is compact in shape. You can buy a multi-functional harvester at the price of an ordinary thresher. Because of its small size and roller wheels, you can put two wooden sticks at the height difference to push the harvester to move on it, and you can also move on very narrow field ridges. The rolling wheels will not affect the harvesting even if there is water in the field. The structure is welded, and any problem can be repaired at home by yourself. The main advantage is that the structure is simple and can be flexibly used in the mountains, and it can also be driven on farmland with large height differences where roads are blocked. The device is constructed of ordinary welded galvanized iron, offering both lightness and strength. The overall design is compact and modular, allowing the threshing unit to operate independently with an external engine. The grain storage bin is removable and equipped with woven bags, allowing selected rice grains to be directly bagged. Its simple structure and significant weight reduction allow it to operate in muddy fields, allowing for threshing after collecting rice ears, making it even more practical. The original push-type handle allows for flexible steering in the field, allowing the cutting platform to be adjusted up and down at any time for precise harvesting.

[0015] As shown in Figure 1, this is a schematic diagram of the overall structure of a miniature drum harvester for muddy fields in mountainous areas of the present application. The overall layout of each device is shown below and is divided into five major parts: 1. threshing assembly 2. power assembly 3. harvesting table assembly 4. drum wheel 5 and other ancillary facilities.

[0016] FIG2 further illustrates the structure of the harvester assembly with support arms for a miniature drum harvester for muddy fields in mountainous areas. Chains 503 and 504 transmit engine power to the auger 102, which drives the straw pusher 101 and the harvester 104. The harvester 104 separates the rice grains. The handrail 506 adjusts the height of the rice to be harvested, and the straw divider 103 adjusts the width of the harvested rice. After the rice is separated, it is pushed by the straw pusher 101 to the auger 102, which pushes the rice to the feed inlet 105 and into the threshing drum 203.

[0017] FIG3 is a schematic diagram of a threshing device assembly with auger discharge. The threshing drum 203 transmits the engine power to the threshing drum 203 through the 503 stripper chain, and the threshing drum 203 rotates. Figure 2The delivered rice is separated from the residue and the rice is screened to the lower discharge port 202 with an auger. The rice leaves and rice residue are discharged through the discharge port 201. The discharge port 202 with an auger is connected to the auger through the 502. The auger chain transmits the power of the engine to the discharge port 202 with an auger. There is a tray 507 under the discharge port. The plastic woven bag is put on the discharge port to load and unload the rice.

[0018] Figure 4 shows a schematic diagram of the drum wheel assembly. The front drum wheel 301 transmits engine power to the front drum wheel 301 via the drum chain 501. The front drum wheel 301 has a groove to prevent slipping during operation in muddy fields and is equipped with a gear lever 401 for forward, reverse, and slow, medium, and fast shifting. The rear drum wheel 302 has no power transmission and functions as a two-wheeled machine. During harvesting, the rear drum wheel 302 can be adjusted up and down using the handrail 506. The rear drum wheel 302 can be lifted off the ground for single-wheel operation. The front drum wheel 301 is designed to be full-width. When encountering large field ridges, two wooden bars can be used to allow the front drum wheel 301 to travel on the bars, thus enabling the machine to overcome obstacles.

[0019] Figure 5 The figure below shows a schematic diagram of the powertrain. The engine 403 is for illustration only; ordinary diesel engines on the market can achieve power output by adding a gear. 402 is the power output gear, which transmits power to all sub-devices.

[0020] Figure 6 Other ancillary facilities include 508, the main frame made of galvanized angle steel, which can be welded easily, significantly reducing costs. 507, the pallet, can be used to hold temporary plastic woven bags for rice transportation, and 506, the handrail, allows for free movement in paddy fields like a wheelbarrow.
