Description

Technical Field

[0001] The invention relates to the field of rice harvesting devices, in particular to a boat-type rice harvesting device. Background Art

[0002] Integrated rice-fish farming is an ecological agricultural model that combines rice planting with aquatic farming such as fish. It can not only increase rice yields, but also provide natural fertilizers for rice through the excrement of aquatic organisms, improve soil structure, and promote rice growth. At the same time, aquatic organisms can also help control pests and weeds in rice fields and reduce the use of pesticides. This model can not only improve food security and nutrition levels, but also bring significant economic benefits. However, when a large number of aquatic organisms such as fish are raised in rice planting ponds, the harvesting mechanism and crawler mobile mechanism of large rice harvesters will cause harm to aquatic organisms. Therefore, it is not easy to use large rice harvesters to mechanized harvesting and threshing of rice. When large rice harvesters walk in the water through crawler mobile mechanisms, the weight and mechanical pressure of the crawlers will damage the geology of the bottom of the water, causing changes in the structure of fish habitats, affecting fish hiding and breeding places, and long-term trampling and friction of the crawlers will physically damage plants and compact the soil, reduce soil permeability, and have a negative impact on the living environment of aquatic plants and animals.

The transmission mechanism is a prior art and will not be described here; the harvesting shovel 15 is slidably connected with a sliding plate 21; the harvesting shovel 15 is provided with two electric push rods 22; the two The telescopic ends of the electric push rods 22 are fixedly connected to the sliding plate 21; the harvesting shovel 15 is slidably connected with a plurality of telescopic slide rods 23; all the telescopic slide rods 23 are fixedly connected to the sliding plate 21; a water pump 3 is installed on the floating boat 11; the liquid inlet end of the water pump 3 is connected with a liquid inlet pipe 31; the liquid inlet end of the liquid inlet pipe 31 penetrates the floating boat 11 downward; a filtering screen is arranged inside the liquid inlet end of the liquid inlet pipe 31 to intercept water debris such as straw and mud; a liquid outlet pipe 32 is fixedly connected to the floating boat 11; The liquid outlet end of the water pump 3 is connected to the liquid outlet pipe 32; the liquid outlet pipe 32 is connected to the telescopic pipe 33; a shunt pipe 34 is fixedly connected to the sliding plate 21; the shunt pipe 34 is connected to the telescopic pipe 33; each telescopic slide rod 23 has a first nozzle 35 passing through it; all the first nozzles 35 are connected to the shunt pipe 34 together; all the telescopic slide rods 23 are set to a progressive distribution structure with a gradually increasing length toward the middle; all the first nozzles 35 are also set to a progressive distribution structure with a gradually increasing length toward the middle.

[0029] like Figure 7-Figure 9As shown, four longitudinal channel structures 110 are provided at the bottom of the floating vessel 11, and the four longitudinal channel structures 110 are respectively located on the left and right sides of the two crawler-type mobile chassis 12; two two-way guide plates 111 are fixedly connected to the bottom of the floating vessel 11, and the two two-way guide plates 111 are respectively located at the front sides of the two crawler-type mobile chassis 12; a plurality of pressure plates 112 are fixedly connected to the bottom of the four longitudinal channel structures 110 of the floating vessel 11; a plurality of second nozzles 36 are fixedly connected to the two two-way guide plates 111, and the second nozzles 36 use electrically controlled movable nozzles, which are used to adjust the water flow to spray in various directions; all the second nozzles 36 are connected to the liquid outlet pipe 32.

[0030] The following are the rice harvesting and threshing process steps of a boat-type rice harvesting device of the present invention.

[0031] The user controls the crawler-type mobile chassis 12 in the cockpit 13 to drive the boat-type rice harvesting device of the present invention to move in the water, and at the same time uses the harvesting shovel 15 to cooperate with the electric threshing drum 16 to harvest and thresh the rice. The threshed rice grains are continuously collected in the collecting cabin 14. The crawler-type mobile chassis 12 moves stably directly on the mud at the bottom of the water. At the same time, the water generates an upward buoyancy on the floating boat 11, which reduces the pressure of the crawler of the crawler-type mobile chassis 12 on the underwater geology, thereby reducing the damage of the crawler to the underwater geological environment during the movement.

[0032] During the process of harvesting and threshing rice with the help of the harvesting shovel 15 and the electric threshing drum 16, the electric push rod 22 pushes the sliding plate 21 to drive the telescopic sliding rod 23 and the first nozzle 35 connected thereto to extend in the forward direction. At the same time, the water pump 3 continuously sucks the water flow under the floating boat 11 through the liquid inlet pipe 31, and the water pump 3 then successively transports the water flow to each first nozzle 35 through the liquid outlet pipe 32, the telescopic pipe 33 and the diversion pipe 34, so that the water flow is sprayed out from each first nozzle 35 in the forward direction, and all the telescopic sliding rods 23 and All the first nozzles 35 are configured to have a progressively increasing length distribution structure toward the middle, so that the telescopic slide rod 23 can push the aquatic organisms in the forward direction to the side during the forward movement, and at the same time, the water flow ejected from the first nozzle 35 continuously drives the pushed aquatic organisms to the side, keeping the aquatic organisms away from the harvesting shovel 15 and the electric threshing drum 16, and preventing the aquatic organisms from swimming to the bottom of the floating boat 11 and close to the crawler mobile chassis 12, causing the working electric threshing drum 16 and the crawler mobile chassis 12 to cause mechanical damage to the aquatic organisms.

[0033] In this process, the second nozzle 36 is an electrically controlled movable nozzle. The second nozzle 36 rotates to face the crawler mobile chassis 12. Part of the water flowing through the liquid outlet pipe 32 will be sprayed toward the crawler mobile chassis 12 through each second nozzle 36. At this time, even if there are a small number of aquatic organisms swimming close to the crawler mobile chassis 12, the sprayed water will also timely drive away the aquatic organisms moving in the forward direction of the crawler mobile chassis 12 to prevent the aquatic organisms from being crushed due to staying in the forward direction of the crawler mobile chassis 12. Some of the aquatic organisms that have been driven away can pass through each pressure plate under the guidance of the two-way guide plate 111 or directly upward. 112, swim to the adjacent longitudinal channel structure 110 on the pontoon 11, and then the aquatic organisms leave backward along the longitudinal channel structure 110 of the pontoon 11. Since a large amount of rice straw will remain in the water after being harvested, when the pontoon 11 passes through these straws, the pressing plate 112 will press the straw structure downward to prevent a large amount of straw from entering the longitudinal channel structure 110 of the pontoon 11 and hindering the aquatic organisms that swim outward, thereby ensuring that the aquatic organisms can smoothly leave along the longitudinal channel structure 110 of the pontoon 11. It should be noted that in deeper waters, the water flow sprayed by the second nozzle 36 can be adjusted to assist the pontoon 11 in moving and turning.

[0034] In addition, as the crawler mobile chassis 12 moves on the mud on the bottom of the water, a large amount of silt will gradually accumulate on the tracks of the crawler mobile chassis 12. The water flow ejected from the second nozzle 36 is continuously sprayed on the tracks of the crawler mobile chassis 12, continuously washing the silt accumulated on the tracks downwards, thereby preventing the crawler mobile chassis 12 from carrying away a large amount of silt during the movement, thereby destroying the original geological features and conditions of the bottom of the water.

[0035] Example 2

[0036] On the basis of Example 1, Figure 1-Figure 9As shown, the floating boat 11 of this embodiment is connected with a circle of fixed frame 41; a circle of mouth-shaped fence 43 is fixedly connected to the fixed frame 41, and the lower side of the mouth-shaped fence 43 is lower than the height of the floating boat 11. When the crawler-type mobile chassis 12 drives the floating boat 11 to move in the water, the mouth-shaped fence 43 on the fixed frame 41 surrounds the floating boat 11, intercepts the aquatic organisms that swim to the bottom of the floating boat 11 and approaches the crawler-type mobile chassis 12, and prevents the crawler-type mobile chassis 12 from harming the aquatic organisms during the movement; the rear side of the mouth-shaped fence 43 is provided with a hollow groove structure 430 corresponding to the number and position of the longitudinal channel structure 110; the second nozzle 36 is an electrically controlled active nozzle. Before the crawler-type mobile chassis 12 drives the floating boat 11 into the water, the second nozzle 36 continuously By rotating in all directions, water is sprayed in all directions from the inside of the mouth-shaped fence 43 to drive away the aquatic creatures around the mouth-shaped fence 43, so as to prevent the aquatic creatures that fail to escape in time from being covered inside the mouth-shaped fence 43 when the mouth-shaped fence 43 enters the water. After the tracked mobile chassis 12 drives the floating boat 11 to completely enter the water, the second nozzle 36 rotates to face the tracked mobile chassis 12. Even if a small amount of small aquatic creatures such as fry pass through the mouth-shaped fence 43 and swim to the bottom of the floating boat 11 close to the tracked mobile chassis 12, the water flow sprayed from the second nozzle 36 drives the aquatic creatures away from the tracked mobile chassis 12. After the aquatic creatures swim into the longitudinal channel structure 110, they can pass through the hollow groove structure 430 to leave the mouth-shaped fence 43.

[0037] Example 3

[0038] On the basis of Example 2, Figure 1-Figure 9 As shown, the fixed frame 41 of this embodiment is slidably connected to the floating boat 11; two electric lifts 42 are installed on the floating boat 11; the telescopic ends of the two electric lifts 42 are fixedly connected to the fixed frame 41; when the crawler mobile chassis 12 walks on land, the electric lift 42 pushes the fixed frame 41 to drive the mouth-shaped fence 43 upward away from the ground, so as to prevent the mouth-shaped fence 43 from affecting the passing performance of the crawler mobile chassis 12 walking on uneven land due to its close distance to the ground; when the crawler mobile chassis 12 walks in water, the electric lift 42 pushes the fixed frame 41 to drive the mouth-shaped fence 43 downward to immerse into the water surface Next, the mouth-shaped fence 43 is used to intercept aquatic organisms in the water; a number of soft ropes 44 are fixedly connected to the lower side of the mouth-shaped fence 43; compared with the mouth-shaped fence 43, the soft ropes 44 are not easily blocked by aquatic debris such as straw and mud, and have stronger passing performance. Therefore, when the electric lift 42 pushes the fixed frame 41 to drive the mouth-shaped fence 43 to immerse below the water surface, the soft ropes 44 can be directly lowered to contact with the mud on the bottom of the water, thereby improving the interception effect on aquatic organisms and greatly reducing the occurrence of aquatic organisms passing through the mouth-shaped fence 43 and the soft ropes 44 to swim to the bottom of the floating ship 11 close to the crawler mobile chassis 12.
