Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, specifically relating to a mud removal device for a water chestnut harvester. Background Technology

[0002] Water chestnuts prefer to grow in ponds or be cultivated in paddy fields. They are usually harvested by hand or using water chestnut harvesting machines.

[0003] Some existing technologies also include mud removal solutions, such as a Chinese patent with publication number CN109328610A, which discloses a mud removal device for a water chestnut harvester. Several mud-pushing devices move around the inner edges of the first and second mounting plates to push the mud from left to right, removing the loose mud covering the water chestnuts. This avoids manual labor, reduces labor intensity, and thus improves the efficiency of water chestnut harvesting.

[0004] However, the method of moving left and right to push the soil in this patent is inefficient, which makes the harvester move slowly and thus affects the overall efficiency of water chestnut harvesting. Summary of the Invention

[0005] The purpose of this invention is to provide a mud removal device for a water chestnut harvester in order to solve the problems mentioned in the background art.

[0006] The present invention achieves the above objectives through the following technical solutions:

[0007] A mud-removal device for a water chestnut harvester, fixedly installed at the front end of the water chestnut harvester, includes:

[0008] A shell having a mud inlet and a mud outlet, the shell having a mud discharge cavity;

[0009] The sludge discharge assembly is located in the sludge discharge cavity; and

[0010] Drive components mounted on the housing;

[0011] The drive component drives the mud discharge component to rotate in the mud discharge cavity. The mud discharge component moves the mud that enters the mud discharge cavity from the mud inlet to the mud discharge outlet and is discharged through the mud discharge outlet.

[0012] Preferably, the housing includes two connecting plates, and a mud baffle and a mud discharge plate are fixedly provided between the two connecting plates. A first gap and a second gap are provided between the mud baffle and the mud discharge plate along the length direction of the mud baffle. The first gap is a mud discharge port, and the second gap is a mud inlet.

[0013] Preferably, the sludge discharge assembly includes a rotating drum rotatably disposed between two connecting plates, the rotating drum having a plurality of limiting holes along its circumference, the top of the rotating drum being in contact with the bottom surface of the sludge discharge plate, a sludge storage space being provided between the rotating drum and the mud baffle, and the distance between the rotating drum and the mud baffle gradually decreasing from bottom to top.

[0014] A connecting rod parallel to the rotating drum is rotatably arranged between the two connecting plates at a non-center position of the rotating drum. A plurality of partition plates are rotatably sleeved on the connecting rod, and the partition plates correspond one-to-one with the limiting holes.

[0015] When the rotating drum rotates, it presses the soil into the storage space through the partition plate. The storage space between adjacent partition plates gradually decreases as the position of the partition plate relative to the mud baffle changes. The soil is discharged when it moves to the first gap.

[0016] Preferably, the mudguard is provided with a plurality of partitions along the length of the connecting rod.

[0017] Preferably, the drive assembly includes two second gears concentrically fixed at both ends of the rotating drum, and the second gears are in a ring shape;

[0018] The top of the mud discharge plate is rotatably connected to a drive shaft via an mounting plate. Both ends of the drive shaft are fixed with a No. 1 gear, and the two No. 1 gears correspond to the two No. 2 gears.

[0019] One end of the drive shaft extends to the outside of the No. 2 gear, and a transmission component is fixedly connected to this end;

[0020] The inner ring of the second gear is rotatably supported, the connecting plate is provided with a slot, the support is provided with a boss mounting rod, the boss mounting rod is fixedly located at the slot, and the connecting rod is rotatably located on the support.

[0021] Preferably, a horizontally positioned conveyor is fixedly installed on the mudguard plate to transport the soil discharged from the first gap to the side of the water chestnut harvester.

[0022] The beneficial effects of this invention are as follows:

[0023] 1. This invention can directly shovel up excess soil in the forward direction of the water chestnut harvester and then transport it to the side of the water chestnut harvester. The process of removing the soil does not affect the forward speed of the water chestnut harvester, ensuring the normal harvesting of water chestnuts and improving the harvesting efficiency.

[0024] 2. This invention uses a rotary method to discharge mud, which has high mud discharge efficiency and will not cause jamming during the mud discharge process, making the mud discharge shaft durable.

[0025] 3. The present invention has a simple structure and ingenious design. It only requires a diesel engine to be connected to the output gearbox to realize the whole action. It has strong linkage, is not easy to break, and is easy to maintain. Attached Figure Description

[0032] The present application will now be described in further detail. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0033] Example 1

[0034] like Figure 1-5 As shown, a mud removal device for a water chestnut harvester is fixedly installed at the front end of the water chestnut harvester. It includes two parallel connecting plates 1. A mud baffle 2 and a mud discharge plate 3 are fixedly installed between the two connecting plates 1. A first gap 4 and a second gap 41 are provided between the mud baffle 2 and the mud discharge plate 3 along the length direction of the mud baffle 2. The first gap 4 is a mud discharge port, and the second gap 41 is a mud inlet. Soil enters from the mud inlet.

[0035] The top of the mud discharge plate 3 is rotatably connected to the drive shaft 10 via the mounting plate, and a No. 1 gear 11 is fixed at both ends of the drive shaft 10.

[0036] A transmission component 19 is fixedly connected to one end of the drive shaft 10. The transmission component 19 uses a 90-degree transmission box, which can be used to complete the steering using two bevel gears. The transmission box is connected to the diesel engine output gearbox via a long shaft, which drives the drive shaft 10 to rotate.

[0037] A rotating roller 5 is rotatably mounted between the two connecting plates 1. A second gear 12 is concentrically fixed at both ends of the rotating roller 5. The second gear 12 is ring-shaped. A support body 13 is rotatably mounted on the inner ring of the second gear 12. A slot 14 is provided on the connecting plate 1. A boss mounting rod 15 is fixed on the support body 13. The boss mounting rod 15 is fixedly mounted at the slot 14, so that the support body 13 is fixedly connected to the connecting plate 1.

[0038] The rotating drum 5 has four sets of holes along its circumference. Each set of holes includes five limiting holes 6 that are equidistantly arranged along the length of the rotating drum 5. The top of the rotating drum 5 is in contact with the bottom surface of the mud discharge plate 3. There is a mud storage space 7 between the rotating drum 5 and the mud baffle 2. The distance between the rotating drum 5 and the mud baffle 2 gradually decreases from bottom to top.

[0039] A connecting rod 8, parallel to the rotating drum 5, is rotatably mounted between the two connecting plates 1 at a non-center position of the rotating drum 5. The connecting rod 8 is rotatably mounted on the support body 13. Several partition plates 9 are rotatably sleeved on the connecting rod 8. The partition plates 9 correspond one-to-one with the limiting holes 6. During the rotation of the rotating drum 5, the length of the partition plates 9 extending out of the rotating drum 5 at different hole positions is different, and the ends of the partition plates 9 repeatedly move in and out of the rotating drum 5.

[0040] A horizontally positioned conveyor 16 is fixedly installed on the mudguard 2 to transport the soil discharged from the first gap 4 to the side of the water chestnut harvester.

[0041] It should be noted that as the water chestnut harvester moves forward, the mud inlet of the mudguard 2 shovels soil into the mud storage space 7. Simultaneously, the diesel engine's transmission outputs power to rotate the drive shaft 10, causing gear 11 to rotate. Gear 11, through its interaction with the gear teeth, drives gear 12 to rotate, which in turn drives the rotating drum 5. Because the partition plate 9 is inserted into the limiting hole 6, the rotating drum 5 rotates, causing the partition plate 9 to rotate as well. Since the rotation center of the partition plate 9 does not coincide with the rotation center of the rotating drum 5, the partition plate 9 extends the longest distance beyond the rotating drum 5 when it reaches its lowest point. At this point, the partition plate 9 is precisely located at the lower end of the mudguard 2. The partition plate 9, mudguard 2, and two connecting plates 1 form a closed space that is spaced apart and movable. The soil moves within this closed space as the partition plate 9 moves. The mud storage space 7 can be divided into several closed spaces.

[0042] The separator 9 enters the mud storage space 7 directly below the mud baffle 2 and rotates upwards within it. Because the rotation center of the separator 9 differs from that of the rotating drum 5, the separator 9 gradually enters the rotating drum 5 during rotation, thus gradually reducing the volume of the enclosed space. The top of the rotating drum 5 contacts the mud discharge plate 3, preventing the mud from passing over it. When the mud reaches the first gap 4, it is squeezed by the rotating drum 5 and the separator 9, causing it to be discharged through the first gap 4 and out of the mud storage space 7. The discharged mud falls onto the conveyor 16 and is transported to the side of the water chestnut harvester, without affecting its normal forward movement.

[0043] Several partitions 18 are fixedly provided on the inner side wall of the mudguard 2 along the length of the connecting rod 8. The partitions 18 are located between adjacent partitions 9 and can be used to block the lateral movement of soil, thereby further improving the efficiency of soil discharge.

[0044] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
