Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery, in particular to a power spiral plow body, a power spiral plow and a power tillage device. Background Technique

[0002] At present, the use of spiral tillage equipment in China is less. Among the currently disclosed patent documents, there is a vertical spiral deep tillage machine, and its tillage equipment structure is as Figure 1 shown, which is a horizontal row of multiple vertical spiral tillage tools. This structure of deep tillage machine is rarely used in actual agricultural tillage because the spiral drilling direction is inconsistent with the forward direction of the tractor, that is, the tractor moves in the horizontal direction, while its tillage equipment rotates in the vertical direction, and the action directions of the two are perpendicular to each other. This tillage equipment can only move forward by scraping the soil on the side of the spiral blade, with large resistance, extremely low working efficiency, and is prone to weed blockage and difficult to operate normally, so it is not practical in actual tillage.

[0003] The existing tractor used for towing agricultural tillage implements is a power machine. The deeper the plowing, the larger the tillage width, and the greater the required traction force. The traction force must be large enough. In addition to the sufficient power of the tractor engine, the adhesion of the tractor must also be large. Therefore, the contact area between the tires of the tractor walking part and the ground should be large, and the weight of the tractor should be heavy enough to increase the pressure, so as to improve the traction force of the tractor. In order to make the tractor meet the requirements of a wider range of agricultural operations, the power of the tractor ranges from 30 horsepower to 300 horsepower or even larger; from simple rear two-wheel drive to complex multi-wheel front and rear drive, the weight ranges from 1 ton to 10 tons; the number of driving tires ranges from 2 rear wheels to 4 front and rear wheels or even more, and the width of each tire ranges from 20 cm to 50 cm, all aiming to increase the adhesion and improve the traction force.

[0004] In addition, for a tractor to have strong traction, the chassis structure of the whole tractor is not only complex but also requires high strength. From using a single gearbox to a double gearbox; from simple forward and reverse gears to shuttle shifting or even power shifting, the requirements for the strength and reliability of the clutch, transmission system, and rear axle are even higher. As a result, the cost price of a tractor will be very expensive, ranging from tens of thousands of yuan to hundreds of thousands of yuan per unit, or even more than one million yuan per unit. In this way, tractors appear to be both complex and expensive, as well as bulky and large. The operation of large tractors requires wide fields, which greatly limits the application in the southern regions of China where the fields are small. Bulky tractors are a disaster for paddy field operations. Because tractors are heavy, especially during paddy field operations, the heavy working machines will press the fields deeper and deeper year by year, seriously damaging the bottom layer of the paddy fields. When plowing, the tractors will sink and it will be difficult to drive. Therefore, more power is needed for plowing. Previously, tractors used for paddy field operations were 25 - 60 horsepower, then 70 - 90 horsepower, and now even 100 - 150 horsepower may not be sufficient to perform well in the fields. If this continues, it will form a vicious cycle and it will become increasingly difficult to plow. On the other hand, currently, the country is carrying out large-scale land consolidation, renovation, and construction of high-standard farmland. The bottom layer of the leveled paddy fields is uneven. When tractors drive agricultural implements into the fields for operation, they will also sink and be unable to move, making it difficult or even impossible to operate. Summary of the Invention

[0005] The technical problem to be solved by the present utility model is to provide a power spiral plow body, a power spiral plow, and a power tillage device. When the power spiral plow body operates, the axial direction is consistent with the forward direction of the device driving its travel, with small tillage resistance and high operation efficiency; the power spiral plow composed of the power spiral plow body can obtain tillage devices with different tillage widths by adjusting the arrangement mode of the power spiral plow body, making it more flexible and convenient to use; the power tillage device only requires a small-power drive for traveling, and most of the power output is used to drive the power spiral plow body to rotate for tillage operations, with small tillage resistance, high operation efficiency, low cost, and relatively small volume and weight.

[0006] The technical solution for solving the above technical problem is: A power spiral plow body includes a spiral plow body, a rotating shaft, a bracket, and a driver installed on the bracket. The spiral plow body includes a plow body, a knife tip provided at the front end of the plow body, and 2 - 20 spiral blades fixed on the plow body. The front end of the spiral blade is set as a spiral edge, and a spiral groove is formed between adjacent two spiral blades.

The blade holder is mounted on the spiral blade in a detachable manner. The blade at the outermost side of the blade holder extends outside the blade holder. The maximum turning radius of the outermost blade is greater than the maximum turning radius of the spiral blade. The blades are inclinedly mounted on the blade holder, and the angle θ between the central axis of the blade and the central axis of the blade holder is 25 - 75°.

[0011] Further, a soil retaining plate is also provided on the support. The soil retaining plate is located above the spiral plow body. A soil throwing impeller is also provided behind the spiral plow body. The soil throwing impeller is mounted on a hollow shaft. The hollow shaft is sleeved on the rotating shaft. The hollow shaft is movably mounted on the support. The hollow shaft is connected to the driver through a second driving wheel, a second driven wheel, and a second driving belt.

[0012] Another technical solution of the present utility model is: a power spiral plow, including a suspension frame and a plurality of power spiral plow bodies mounted on the suspension frame. The power spiral plow body is the above-mentioned power spiral plow body. The plurality of power spiral plow bodies are either arranged in a V - shape on the hypotenuse of the suspension frame; or the plurality of power spiral plow bodies are arranged in a straight line on the hypotenuse of the suspension frame, that is, an angle δ is formed between the central connection line of the plurality of power spiral plow bodies and the working travel direction line, and the angle δ is 45 - 90°.

[0013] Further, the spiral plow body is mounted on the suspension frame by a connecting frame. The connecting frame is composed of a mounting plate and a connecting plate. A plurality of long - strip mounting holes are formed on the mounting plate. The connecting frame is mounted on the suspension frame, and the support of the power spiral plow body is mounted on the connecting frame through bolts and the long - strip mounting holes.

[0014] Another technical solution of the present utility model is: a power tillage device, including a tractor and a power spiral plow mounted on the tractor. The power spiral plow is the above - mentioned power spiral plow. The tractor includes a power system that simultaneously provides traveling power for the tractor and working power for the power spiral plow.

[0015] Further, the tractor includes a rear drive axle and a suspension lifter for mounting a power spiral plow, and the power system is an extended-range power system, a pure electric power system, a power generation power system or a hydraulic power system.

[0016] The extended-range power system includes an engine, a generator, a power battery, an electric motor and a hydraulic oil pump. The engine directly drives the generator and the hydraulic oil pump. The hydraulic oil pump provides power for the suspension lifter. The generator provides power for the power battery.

[0017] The pure electric power system includes a power battery and an electric motor. The power battery provides power for the electric motor. The electric motor drives the rear drive axle of the tractor. The power battery provides power for the suspension lifter. The power battery also provides power for the power spiral plow.

[0018] The power generation power system includes an engine, a generator and a hydraulic oil pump. The engine directly drives the generator and the hydraulic oil pump. The engine drives the rear drive axle through a transmission system. The hydraulic oil pump provides power for the suspension lifter. The generator provides power for the power spiral plow.

[0019] The hydraulic power system includes an engine and a hydraulic oil pump. The engine directly drives the hydraulic oil pump. The engine drives the rear drive axle through a transmission system. The hydraulic oil pump provides power for the power spiral plow and the suspension lifter.

[0020] Due to the adoption of the above technical solutions, the utility model has the following beneficial effects:

[0021] 1. The spiral plow body of the power spiral plow of the utility model is arranged horizontally. When it works, the axis direction of drilling into the soil is parallel to the advancing direction of the equipment driving it. The spiral plow body is correspondingly provided with spiral blades and spiral edges. According to the characteristics of the spiral surface shape, the spiral surface blade has the smallest rotational torque. As the spiral plow body rotates, the soil blocks cut by the front spiral edge flow smoothly along the spiral groove under the action of slip and will not get stuck, so that the resistance of the spiral plow body is extremely small and there is no obstacle to rotation, the soil cutting is light and stable, the soil discharging is smooth, and the use efficiency is high.

[0022] 2. The power spiral plow of the utility model can arrange the power spiral plow bodies in a straight-line inclination or a V-shaped arrangement according to the requirements of the operation tillage width, and can also adjust the distance between two adjacent power spiral plow bodies to obtain different tillage effects. That is, through different arrangements of the power spiral plow bodies, a dynamic tillage operation device with different tillage widths and operation effects can be obtained, and the operation is more flexible and convenient, and the applicable range is wide.

[0023] 3. The power tillage equipment of the present utility model only requires a small-power drive to move forward, and most of the power output is used to drive the power spiral plow for tillage operations. In this way, it can be driven to move with relatively small power, and even a simple two-wheel drive structure can be adopted. The price cost is significantly lower than that of the existing large-horsepower tractors, and it is small in size and light in weight, making it more convenient to move in the fields.

[0024] 4. When the tillage width of the power tillage equipment needs to be increased during operation, mainly increase the power supply or hydraulic supply, which has little impact on the walking part and transmission part of the power tillage equipment. That is to say, when the one-time operation amount of the power tillage equipment needs to be increased, the increase in the manufacturing cost of the power tillage equipment is not large. In other words, a power tillage equipment with a relatively small size and relatively low price cost can drive a power spiral plow with a relatively much wider tillage width, thus greatly reducing the input cost of agricultural tillage.

[0025] Next, in combination with the drawings and embodiments, the technical features of a power spiral plow body, a power spiral plow, and a power tillage equipment of the present utility model will be further described. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] Figure 9 The arrow in the figure indicates the rotation direction of the spiral plow body. Detailed implementation mode Embodiment 1:

[0056] A power spiral plow body, as Figures 2 - 3 shown, includes a spiral plow body 1, a rotating shaft 2, a bracket 3, and a driver 8 installed on the bracket. The driver 8 is a motor or a hydraulic motor. When the supplied energy is electric power, the driver selects a motor; when the supplied energy is hydraulic oil, the driver selects a hydraulic motor. The spiral plow body includes a plow body 101, a knife tip 104 provided at the front end of the plow body, and 4 spiral blades 102 fixed on the plow body. The front end of the spiral blade 102 is provided with a spiral edge 103. The spiral edge 103 is inclined, and the included angle α between the spiral edge 103 and the central axis of the plow body 101 is 30 - 90°, preferably 60 - 80°. Such a setting can make the spiral plow body enter the soil stably. The knife tip 104 is formed by the intersection of multiple spiral edges. A spiral groove is formed between adjacent two spiral blades 102. The plow body 101 of the spiral plow body is installed on the rotating shaft 2. The rotating shaft is movably installed on the bracket 3. A first driven wheel 5 is installed on the rotating shaft, and a first driving wheel 7 is installed on the driver 8. The first driving wheel 7 and the first driven wheel 5 are connected by a first drive belt 6. A soil retaining plate 9 is further provided on the bracket. The soil retaining plate 9 is located above the spiral plow body 1.

[0057] As a variation of this embodiment, the number of the spiral blades can be increased or decreased according to the actual situation, and can be 2, 3 or more, generally 2 - 20, preferably 3 - 8. Embodiment 2:

[0058] A powered spiral plow body, as Figures 4 - 5 shown. Its basic structure is the same as that of Embodiment 1, except that: the knife tip 104 at the front end of the plow body 101 is a spiral head, and the spiral head includes a conical body 1041 and spiral blades 1042 installed on the conical body. The taper angle β of the conical body is 20 - 120°, preferably 30 - 60°. The spiral head is provided to further make the spiral plow body enter the soil more stably. Embodiment 3:

[0059] A powered spiral plow body, as Figures 6 - 9 shown. Its basic structure is the same as that of Embodiment 2, except that: a tillage knife 105 is further installed on the spiral edge 103. The tillage knife 105 includes a knife holder 1051 and a plurality of knife blades 1052 fixed on the knife holder. The knife holder 1051 is installed on the spiral edge 103 through bolts. The knife blade installed on the outermost side of the knife holder extends outside the knife holder, and the maximum turning radius of the outermost knife blade 1052 is greater than the maximum turning radius of the spiral blade 102. The knife blade 1052 is inclinedly installed on the knife holder, and the included angle θ between the central axis of the knife blade and the central axis of the knife holder is 25 - 75, preferably 30 - 60°. The tillage knife is provided to make the spiral plow body have stronger soil entry, soil cutting, and soil crushing capabilities and obtain a better tillage effect. The knife blade rotates and is inclined at an angle θ on the blade holder, enhancing the soil entry, soil cutting, and soil crushing capabilities during rotation and greatly reducing the rotation operation resistance. Embodiment 4:

[0060] A powered spiral plow body, as Figures 10 - 11 shown. Its basic structure is the same as that of Embodiment 3, except that: a soil throwing impeller 10 is further provided behind the spiral plow body 1. The soil throwing impeller is directly installed on the rotating shaft 2, and the soil throwing impeller 10 and the spiral plow body 1 rotate synchronously with the rotating shaft 2 at the same speed. Embodiment 5:

[0061] A powered spiral plow body, as Figure 12 shown. Its basic structure is the same as that of Embodiment 3, except that: a soil throwing impeller 10 is further provided behind the spiral plow body 1. The soil throwing impeller 10 is installed on a hollow shaft 11, the hollow shaft 10 is sleeved on the rotating shaft 2, the hollow shaft 11 is movably installed on the bracket 2, and the hollow shaft 10 is connected to the driver 8 through a second driving wheel 14, a second driven wheel 12, and a second driving belt 13. The soil throwing impeller 10 rotates synchronously with the hollow shaft 11, the spiral plow body 1 rotates synchronously with the rotating shaft 2, and the rotation speeds of the soil throwing impeller 10 and the spiral plow body 1 are different.

[0062] The power spiral plow bodies described in Embodiments 1-5 are equivalent to augers. When operating, the axis direction of the spiral plow body drilling into the land is parallel to the advancing direction of the equipment driving it. The function of the spiral blade or tillage knife of the spiral plow body is to cut and break the soil. The cut soil blocks flow backward along the spiral grooves between the spiral surfaces, with small resistance and strong ability to laterally throw, break, and cover the soil. When a soil-throwing impeller is provided, the function of the soil-throwing impeller is to strengthen the lateral soil throwing, breaking, and covering.

[0063] In Embodiments 4-5, the number of blades of the soil-throwing impeller can be single or multiple, preferably 2-3. The blades can be set as straight or curved surfaces according to tillage requirements. The soil-throwing impeller is installed behind the spiral plow body. The soil-throwing impeller rotates at the same speed or a different speed from the spiral plow body, and throws the soil blocks flowing backward along the spiral surface in the direction of centrifugal force onto the plowed land, so that the soil blocks are further broken and covered flat. In Embodiment 5, an additional driving device is added to make the rotation speed of the soil-throwing impeller faster than that of the spiral plow body, and better soil breaking and soil covering effects can be obtained to meet various land preparation requirements. Embodiment 6:

[0064] A power spiral plow, as Figure 13 shown, includes a suspension frame 15 and a plurality of power spiral plow bodies P installed on the suspension frame. The power spiral plow bodies are the power spiral plow bodies described in Embodiments 1-5. The plurality of power spiral plow bodies are arranged in a straight line and installed on the hypotenuse of the suspension frame, that is, an included angle δ is formed between the central connection line of the plurality of power spiral plow bodies and the working travel direction line. The included angle δ is 45-90°, preferably 45-75°. To ensure that the soil blocks thrown outward by the latter power spiral plow body during operation do not cover the previous power spiral plow body. Embodiment 7:

[0065] A power spiral plow, as Figure 14 shown, includes a suspension frame 15 and a plurality of power spiral plow bodies P installed on the suspension frame. The power spiral plow bodies are the power spiral plow bodies described in Embodiments 1-5. The plurality of power spiral plow bodies are arranged in a V shape and installed on the hypotenuse of the suspension frame.

[0066] In Embodiments 6-7, the spiral plow body is installed on the suspension frame 15 by a connecting frame 16. As Figures 17 - 18 shown, the connecting frame 16 is composed of a mounting plate 161 and a connecting plate 162. A plurality of long strip-shaped mounting holes 1611 are opened on the mounting plate. The connecting frame 16 is installed on the suspension frame 15. The bracket 3 of the power spiral plow body is installed on the connecting frame 16 through bolts and the long strip-shaped mounting holes 1611. The installation position of the power spiral plow body can be adjusted through the long strip-shaped mounting holes 1611 so that the power spiral plow can obtain different tillage widths and tillage effects.

[0067] For the power spiral plow described in Embodiment 6 - Embodiment 7, the diameter of the spiral plow body determines the maximum tillage depth. The larger the diameter, the deeper the tillage depth. The tillage depth can be adjusted appropriately within the diameter range. The diameter of the spiral plow body can be 200 - 600 mm, preferably 300 - 400 mm. The diameter of the spiral plow body not only determines the tillage depth, but also determines the tillage width of the power spiral plow. However, the main factors determining the tillage width are the number of power spiral plow bodies installed on the suspension frame and the degree of overlap. The more power spiral plow bodies are installed, the wider the tillage width. The greater the degree of overlap, the relatively smaller the tillage width. In addition, the size of the degree of overlap affects the size of the upper and lower missed tillage soil blocks, which can be appropriately selected and adjusted according to tillage requirements. It is preferably that the diameter of the power spiral plow body overlaps by one - quarter (as Figure 20 shown). Also, adjusting the tillage depth within the diameter range of the spiral plow body can affect the size of the upper missed tillage soil blocks. When tilling with a power spiral plow, small ditches are formed at the bottom of the tillage land. The depth of the ditches is related to the degree of overlap of the power spiral plow bodies. The greater the degree of overlap, the smaller the ditches, and vice versa (as Figures 19 - 21 shown, Figure 19 where H represents the tillage depth, D represents the center - to - center distance between two adjacent power spiral plow bodies, and L represents the tillage width). There are small ditches at the tillage bottom, which is beneficial for water and fertilizer conservation and can improve the drought - resistance ability of crops. Embodiment 8:

[0068] A power tillage device, as Figure 22 shown, includes a tractor and a power spiral plow installed on the tractor. The power spiral plow is the power spiral plow described in Embodiment 6 - Embodiment 7. The tractor includes a power system that simultaneously provides driving power for the tractor and operating power for the power spiral plow.

[0069] The tractor includes a rear drive axle and a suspension lifter for installing the power spiral plow. The power system is an extended - range power system. The extended - range power system includes an engine, a generator, a power battery, a motor, and a hydraulic oil pump. The engine directly drives the generator and the hydraulic oil pump. The hydraulic oil pump provides power for the suspension lifter. The generator provides power for the power battery. The power battery provides power for the motor. The motor provides power for the rear drive axle of the tractor. The power battery also mainly provides power for the power spiral plow.

[0070] In this embodiment, the engine and the generator form an extender. The extender charges the power battery through a battery management system. The power battery uses a small part of the energy to drive the motor. The motor drives the rear drive axle to move, and the front axle plays a guiding role. The power battery mainly supplies power to the power spiral plow through a power spiral plow controller, and drives the spiral plow body to rotate into the soil to cut and throw the soil through a power spiral plow motor to complete tillage. The most important task of the extender is to provide a strong power source for the power spiral plow. Embodiment 9:

[0071] A power tillage device, such as Figure 23 shown, comprising a tractor and a power spiral plow mounted on the tractor. The power spiral plow is the power spiral plow described in Embodiment 6 - Embodiment 7. The tractor includes a power system that simultaneously provides walking power for the tractor and operating power for the power spiral plow.

[0072] The tractor includes a rear drive axle and a suspension lifter for mounting the power spiral plow. The power system is a pure - electric power system, which includes a power battery and an electric motor. The power battery provides power for the electric motor, and the electric motor drives the rear drive axle of the tractor. The power battery provides power for the suspension lifter and also provides power for the power spiral plow. The most important task of the pure - electric power system is to provide a strong power source for the power spiral plow. Embodiment 10:

[0073] A power tillage device, such as Figure 24 shown, comprising a tractor and a power spiral plow mounted on the tractor. The power spiral plow is the power spiral plow described in Embodiment 6 - Embodiment 7. The tractor includes a power system that simultaneously provides walking power for the tractor and operating power for the power spiral plow.

[0074] The tractor includes a rear drive axle and a suspension lifter for mounting the power spiral plow. The power system is a power - generating power system, which includes an engine, a generator, and a hydraulic oil pump. The engine directly drives the generator and the hydraulic oil pump. The engine drives the rear drive axle through a transmission system. The hydraulic oil pump provides power for the suspension lifter. The generator mainly provides power for the power spiral plow. The engine drives the generator to generate electricity, and the electricity is supplied to the power spiral plow through the power spiral plow controller and drives the spiral plow body to rotate into the soil to cut, throw soil, and complete tillage. That is, a generator is added or enlarged on an existing tractor to provide power for the power spiral plow. Embodiment 11:

[0075] A power tillage device, such as Figure 25 shown, comprising a tractor and a power spiral plow mounted on the tractor. The power spiral plow is the power spiral plow described in Embodiment 6 - Embodiment 7. The tractor includes a power system that simultaneously provides walking power for the tractor and operating power for the power spiral plow.

[0076] The tractor includes a rear drive axle and a hitch lift for mounting a power spiral plow. The power system is a hydraulic power system, which includes an engine and a hydraulic oil pump. The engine directly drives the hydraulic oil pump, and the engine drives the rear drive axle through a transmission system. The hydraulic oil pump provides power for the hitch lift on the one hand and mainly provides power for the power spiral plow on the other hand. The hydraulic oil supplies pressure oil to the power spiral plow through a power spiral plow controller and a hydraulic multi-way valve. The power spiral plow is driven by a hydraulic motor to rotate the plow body into the soil for cutting and throwing soil, completing the tillage. That is, a hydraulic pump is added or enlarged on the existing tractor to provide a power source for the power spiral plow.

[0077] The biggest feature of the power tillage equipment described in Embodiments 8 - 11 is the power supply. That is, in addition to using a small part of its power to tow the power spiral plow to move forward, the tractor mainly provides power supply (electric or hydraulic) for the power spiral plow. Since the operation is carried out by using a self-powered tillage equipment, the tractor does not need to be equipped with a power output mechanism, which not only saves costs but more importantly greatly reduces the operation safety risks. The remaining parts of the tractor not specifically described are the same as the prior art and will not be elaborated here.

[0078] The rotational speed of the cutter shaft driven by the gearbox of a general existing rotary tiller for tillage is fixed, while the forward speed of the tractor is changed by a gear-type gearbox. Neither the rotational speed of the rotary tiller nor the forward speed of the tractor can be steplessly variable, making it difficult to match the forward speed of the tractor with the rotational speed of the rotary tiller. However, the power tillage equipment of the present utility model driving the power spiral plow for operation can solve this problem. According to the working characteristics of the motor and the hydraulic motor, through adjustment by the control board, when driving the plow body to rotate for operation, the rotational speed of the spiral blade can reach stepless speed regulation. In this way, the traveling part and the power tillage part of the power tillage equipment can respectively achieve stepless adjustment. Under the operation and adjustment of the control board, the forward speed of the power tillage equipment and the rotational speed of the power tillage equipment can easily obtain an effective and reasonable match, enabling the tillage to achieve the best operation effect, reducing the operation cost, and improving the operation efficiency.
