Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, and in particular to a deep-dredging and stone-retrieving machine for preventing damage to farmland. Background Technology

[0002] The country is currently vigorously developing rural agriculture, and deep plowing can increase crop yields. Especially in hilly and mountainous areas, deep plowing is a necessary step in land consolidation. It has been widely accepted by farmers, leading to the emergence of various deep plowing machines on the market. Traditionally, deep plowing was done in two steps: deep plowing followed by rotary tillage and pulverization, which was inefficient. In hilly areas, the soil often contains many rocks and tree roots, which can easily damage the machine during deep plowing or rotary tillage, and these rocks and roots cannot be brought to the surface. Summary of the Invention

[0003] This invention addresses the technical problems of low efficiency and easy damage to farm implements during deep plowing by providing a high-efficiency, damage-resistant deep plowing and stone-removing machine for farmland.

[0004] This utility model provides a damage-resistant deep-drilling stone-retrieving machine for farmland, which includes a frame unit, a deep-drilling stone-retrieving mechanism and a power unit. The power unit is equipped with a universal coupling. The deep-drilling stone-retrieving mechanism includes a deep-drilling main shaft and deep-drilling gears. The deep-drilling gears are connected to the deep-drilling main shaft through mounting pins and safety pins. The universal coupling is connected to the deep-drilling main shaft through chain drive.

[0005] Preferably, the deep-drilling spindle is provided with a deep-drilling bracket, and the deep-drilling bracket and the deep-drilling teeth are provided with mounting holes and safety pin holes.

[0006] Preferably, the power unit is equipped with a differential, which is connected to the universal coupling, and the chain drive is provided in two sets, which are respectively connected to the power outputs at both ends of the differential.

[0007] Preferably, the power unit is further provided with an energy storage disk, which is disposed between the differential and the universal joint.

[0008] Preferably, a drive shaft and a rigid coupling are further provided between the differential and the chain drive.

[0009] Preferably, an auxiliary device is also provided, which is installed on the frame unit. The auxiliary device is provided with two small ditching plows, one on each side of the lower end of the front crossbeam of the frame unit. Three deep loosening teeth are provided between the small ditching plows. A scraper is provided at the rear end of the frame unit.

[0010] Preferably, the deep-drill spindle seal adopts a double-layer sealing method consisting of a sealing ring and a mechanical seal component.

[0011] Preferably, the chain drive is further provided with a tensioning wheel.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model has a low rotation speed, light wear on the plow teeth, and is durable. Compared with ordinary rotary tillers, the wear resistance of the plow teeth is more than 10 times higher, and it is economical.

[0014] 2. This utility model has coarse teeth, which can dig hard soil and adopts a protective device (with anti-damage bolts as safety pins, which cut off the safety pins when encountering large hard objects to protect the teeth from damage).

[0015] 3. This utility model can dig to a depth of more than 50 cm and can adapt to raw land. After deep digging, the yield of hilly and mountainous land can be increased by more than 30%.

[0016] 4. Due to its low rotation speed, this invention prevents the soil from being pulverized. It offers good permeability and rapid water infiltration, making it more suitable for crops like ginger that require pre-irrigation.

[0017] 5. This utility model completes deep tillage and rotary tillage in one step, achieving the effect of deep tillage followed by rotary tillage. The depth is deeper than that of ordinary operations, achieving the effect of two operations in ordinary methods. The soil layer of more than 50 cm can store a large amount of water and has the same permeability as the root system, so there will be no reduction in yield even in severe drought.

[0018] 6. This utility model is suitable for various irregular terrains. It can be used to dig deep ditches without leaving any edges or corners, especially in mountainous areas.

[0019] 7. This utility model adopts differential and sprocket transmission at both ends, which changes the central transmission position of the rotary tiller, and allows for deep tilling without leaving any dead corners.

[0020] 8. This utility model has auxiliary plows on both sides of the front end. The auxiliary plows are in front of the sprocket. A chain box is installed on the outside of the sprocket to protect the chain. The auxiliary plow can plow a deep trench, which makes it easier for the chain box to sink. This can reduce the length of the digging teeth or increase the digging depth with the same tooth length.

[0021] 9. This utility model has three deep loosening teeth on the front support of the gear shaft, which can prevent the gear from pushing the car forward when it is back to pry, and also reduce the workload of the back gear and the transmission system.

[0022] 10. This utility model adds a scraper to the rear of the frame, which can further level and smooth the field after rotary tillage. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments, so that those skilled in the art to which the present invention pertains can easily implement the present invention.

[0030] Example: Figure 1-4 As shown, this utility model comprises a frame unit 100, a power unit 200, a deep-digging and stone-retrieving mechanism 300, and an auxiliary device 400. The power unit 200, the deep-digging and stone-retrieving mechanism 300, and the auxiliary device 400 are mounted on the frame unit 100, and the power unit 200 is connected to the deep-digging and stone-retrieving mechanism 300.

[0031] The frame unit 100 comprises a frame 101, a front web plate 102, a first side web plate 103, a second side web plate 104, and a connection port 105. The frame 101 is a frame type, including front and rear crossbeams and longitudinal beams welded from various profiles. The front web plate 102, the first side web plate 103, and the second side web plate 104 are welded to three sides of the frame 101. The front end of the frame 101 is provided with a connection port 105 for connection with a tractor.

[0032] The power unit 200 consists of a universal coupling 201, a differential 202, a first rigid coupling 203, a second rigid coupling 213, a first drive shaft 204, a second drive shaft 214, a first drive sprocket 206, a second drive sprocket 216, a first drive chain 207, a second drive chain 217, a first driven sprocket 208, a second driven sprocket 218, a first bearing housing 205, a second bearing housing 209, a third bearing housing 215, and a fourth bearing housing 219.

[0033] The differential 202 is fixed to the frame 101 with screws. The input end of the differential 202 is connected to the universal coupling 201, and the output end is connected to the first drive shaft 204 and the second drive shaft 214 via the first rigid coupling 203 and the second rigid coupling 213, respectively.

[0034] The first bearing housing 205 and the second bearing housing 209 are bolted together at the front and rear positions of the first side web 103. The first drive shaft 204 passes through the end of the first bearing housing 205 and is fitted with a first drive sprocket 206. The first drive sprocket 206 is connected to the first driven sprocket 208 via a first drive chain 207. Similarly, the transmission principle is the same on the other side; the third bearing housing 215 and the fourth bearing housing 219 are bolted together at the front and rear positions of the second side web 104. The second rigid coupling 213 transmits power from the second drive shaft 214 to the second driven sprocket 218 via a chain drive.

[0035] Tensioning pulleys are also provided on the first transmission chain 207 and the second transmission chain 217. Chain boxes for protecting the chains can also be installed on the outside of the first transmission chain 207 and the second transmission chain 217 (the chain boxes are not marked in the figure for the sake of showing the transmission chains).

[0036] An energy storage disc 210 is also provided between the differential 202 and the universal coupling 201. The energy storage disc 210 is a flywheel that stores engine energy to overcome the resistance of other components. When encountering hard rocks, the energy storage disc 210 can prevent power backlash from damaging the power source gearbox.

[0037] The deep-digging stone-retrieving mechanism 300 consists of a deep-digging main shaft 301, deep-digging gears 302, mounting pins 303, and safety pins 304. The two ends of the deep-digging main shaft 301 are mounted on the first driven sprocket 208 and the second driven sprocket 218. The deep-digging main shaft 301 passes through the second bearing seat 209 and the fourth bearing seat 219 and is supported on the two first side web plates 103 and the second side web plate 104.

[0038] The deep-drilling spindle 301 is equipped with a mounting bracket 305 for the deep-drilling gear 302, which is welded to the spindle. The bracket 305 has a mounting hole 306 and a safety pin hole 307. The gear also has two holes, corresponding to the mounting hole 306 and the safety pin hole 307 respectively. The deep-drilling gear 302 is connected to the spindle via a mounting pin 303 and a safety pin 304. The safety pin 304 has appropriate hardness; when encountering significant resistance during operation, it can be cut, disabling the gear 302 and protecting it.

[0039] The deep-drill spindle seal adopts a double-layer sealing method, consisting of an installation sealing ring and a mechanical seal component.

[0040] The auxiliary device 400 includes two auxiliary plows 401 installed on both sides of the front crossbeam, and three deep tillage plows 402 between the two auxiliary plows 401. The two auxiliary plows 401 separate the mud to prepare for the chain box to sink, which can reduce the length of the plow teeth and increase the tillage depth. The auxiliary plows 401 are ordinary plows. The deep tillage plows 402 consist of a deep tillage tooth (plow column) with a plow blade welded on it. When tilling the land, the deep tillage tooth can be inserted into the ground to loosen the soil, but the plow blade will turn the soil to one side, and at the same time, a ditch will be left behind the plow blade.

[0041] The significance of the deep tillage plow 402 lies in two aspects. First, it loosens the soil in advance, reducing resistance for subsequent rotary tillage; after all, it acts like a knife, first splitting the soil. Second, the deep tillage teeth 302, when rotary tilling, are pushed forward by the soil resistance. Since both the deep tillage teeth and the auxiliary plow require forward pulling force, this creates a certain balance between the two, preventing the tillage teeth from pushing the tractor forward while reducing the workload on the rear tillage teeth and transmission system. At the rear of the deep tillage and stone-removing machine is a scraper 403, which further smooths and levels the tilled field.

[0042] In normal operation, the tractor transmits power to the differential 202. The differential 202 then transmits the power from both ends through the drive sprocket, drive chain, and driven sprocket to the deep-digging main shaft 301 via two drive shafts. The deep-digging main shaft 301 rotates at low speed to till the land. Due to the low speed, the deep-digging stone-removing machine can till 50 cm of land in a single pass. When encountering hard stones or other objects, it can turn the stones to the surface. If the stones are large and obstruct tillage, the digging teeth can cut the safety pin 304 to filter them and prevent damage to the digging teeth 302. After deep tilling, the safety pin 304 can be replaced to restore normal operation.

[0043] During rotary tillage, the differential 202 transmission is used so that if one side sprocket breaks, it will not affect the other side from continuing to work. At the same time, an energy storage plate 210 is added to the front end of the differential 202 to prevent power backlash from damaging the power source gearbox when encountering hard rocks.

[0044] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the scope of the claims of the present invention should be within the protection scope of the present invention.
