Description

Technical Field

[0001] The present invention relates to the technical field of forage planting, and particularly relates to a furrow-opening seeding machine for forage planting. Background Art

[0002] Forage is an important material basis for animal husbandry. Sowing is a key link in the process of forage planting. Since there are many types of forage and the seed particle sizes are different, the requirements for sowing depth are also different. Sowing technology directly affects the emergence quality, growth and development, and yield formation of forage. Through scientific sowing methods and management measures, the growth quality and yield of forage can be effectively improved, providing high-quality feed resources for animal husbandry and also providing strong support for the sustainable development of animal husbandry.

[0003] At present, for large-area forage planting, a furrow-opening seeding machine is usually used. The existing furrow-opening seeding machine for forage planting is similar to that for planting crops. It generally includes a tractor. There is a furrow-opening mechanism at the front end of the vehicle body, and a seed-feeding seeding mechanism in the middle of the vehicle body, which can sow grass seeds in the furrows opened. Some also have a pressing mechanism at the rear end of the vehicle body, so that when the tractor moves, the front end opens the furrow, the seeding mechanism then sows, and the pressing mechanism at the rear covers the soil and presses on the sown seeds. It integrates multiple functions and can complete multiple steps in one operation. Currently, the common furrow-opening seeding machine usually has multiple furrow-opening wheels arranged on a rotating shaft. The rotating shaft is driven by a motor to rotate, so that the multiple furrow-opening wheels rotate to open the furrow. However, its furrow-opening wheels are fixedly arranged and cannot be adjusted at any time according to different forage types. If different forages need to be planted, it is necessary to stop the machine and remove them for adjustment, which is a cumbersome process and reduces work efficiency. Summary of the Invention

[0021] Embodiment 1 The embodiment of the present invention provides a forage planting ditching and seeding machine as Figure 1As shown in the figure, it includes: a rotating shaft 1, a ditching structure 2, a lifting assembly, and a driving member. The driving structure includes the rotating shaft 1 and the driving member. The rotating shaft 1 is horizontally arranged. The driving member has an output end, and the output end of the driving member is connected to the rotating shaft 1. The driving member is used to drive the rotating shaft 1 to rotate. The driving member can be a motor or a servo or other rotary driving structure. When in use, the vehicle body drives the whole device to move on the ground. When moving, the driving member works to drive the rotating shaft 1 to rotate. In addition, this device is a ditching seeder, and the vehicle body should be equipped with a seeding mechanism and a pressing mechanism. The seeding mechanism and the pressing mechanism can adopt the existing technology; multiple groups of ditching structures 2 are arranged in a line on the rotating shaft 1, and multiple groups of ditching structures 2 are distributed along the axial direction of the rotating shaft 1. In this embodiment, the ditching structure 2 includes a runner 21, a plurality of ditching columns 22, and a fixing component 23. When the rotating shaft 1 rotates, the side wall of the runner 21 contacts the ground and can roll on the ground. A chute 24 runs through the middle of the runner 21. The chute 24 is vertically opened at the central position of the runner 21. The rotating shaft 1 is sleeved in the chute 24, and the rotating shaft 1 is slidably connected to the chute 24. As Figure 2 , Figure 3 shown, the upper and lower ends of the chute 24 are semi-circular to match the circumferential direction of the rotating shaft 1. The length direction of the chute 24 is perpendicular to the axial direction of the rotating shaft 1. When the rotating shaft 1 slides to one end of the chute 24, it is in the first position ( Figure 2 , Figure 3 the top end of the chute 24 shown). When the rotating shaft 1 is in the first position, the rotating shaft 1 is coaxial with the runner 21. When the rotating shaft 1 slides to the other end of the chute 24, it is in the second position ( Figure 2 , Figure 3At the bottom end of the shown chute 24), a plurality of ditching columns 22 are evenly arranged in the circumferential direction of the runner 21. Similar to a tire, a plurality of ditching columns 22 that can be inserted into the soil are arranged in the circumferential direction. When the rotating shaft 1 slides to the top end of the chute 24, the rotating shaft 1 is coaxial with the runner 21. The fixing assembly 23 is arranged between the runner 21 and the rotating shaft 1, and the fixing assembly 23 connects the runner 21 and the rotating shaft 1 together, which can fix the position of the rotating shaft 1 relative to the runner 21. A plurality of lifting assemblies respectively correspond to a plurality of ditching structures 2. The lifting assembly has a lifting end, and the lifting end is rotatably connected to the runner 21. The lifting assembly does not affect the rotational movement of the runner 21. The lifting end is used to drive the runner 21 to lift. When ditching, the rotating shaft 1 slides to the top end of the chute 24, and the rotating shaft 1 is coaxial with the runner 21. The runner 21 and the rotating shaft 1 are connected together through the fixing assembly 23. When adjusting the ditching spacing, the runner 21 and the rotating shaft 1 are separated through the fixing assembly 23, and the runner 21 is driven to lift through the lifting assembly, so that the rotating shaft 1 slides to the bottom end of the chute 24, and the runner 21 is separated from the ground and is in a non-working state. When this device is in use, the driving part works to drive the rotating shaft 1 to rotate. When the rotating shaft 1 rotates, the runner 21 rotates to drive the ditching columns 22 to ditch. This device is provided with a plurality of ditching structures 2 and a plurality of lifting assemblies. The lifting assembly can lift the ditching structure 2, so that the rotating shaft 1 moves in the chute 24. When it is necessary to adjust the ditching spacing, the unused ditching structure 2 can be lifted by adjusting, and the spacing between the remaining adjacent ditching structures 2 is adjusted to the required spacing, so that the ditching spacing can be adjusted according to different forage types, improving work efficiency. Among them, in the ditching structure 2 to be lifted after adjustment, the fixing assembly 23 separates the runner 21 from the rotating shaft 1, which is convenient for the rotating shaft 1 to slide up in the chute 24. The remaining ditching structures 2 need to ditch, so the runner 21 needs to rotate with the rotating shaft 1, and the fixing assembly 23 is needed to connect the runner 21 and the rotating shaft 1 together. In addition, when different types of forage are planted in adjacent two ditches, this device is also applicable, and the ditching structure 2 can be adjusted so that the spacing between adjacent two ditches is different, with a wider application range. Among them, when adjusting the ditching spacing, it is necessary to stop the machine to adjust the ditching structure 2. First, the driving part stops driving the rotating shaft 1 to rotate, and when the chute 24 is in Figure 2 , Figure 3 the vertical state, it is at the zero position. When the rotating shaft 1 stops rotating, it is always at the zero position. In this way, when the lifting assembly drives the runner 21 to rise, the rotating shaft 1 can slide to the bottom end of the chute 24.

[0022] This embodiment provides a specific way to fix the fixing component 23. Further, a chamber 25 is formed in the runner 21, and the fixing component 23 is arranged in the chamber 25. The fixing component 23 includes: a plug rod 231 and a telescopic member. The plug rod 231 is horizontally arranged in the chamber 25. Here, "horizontally" means that when the chute 24 is in a vertical state, the plug rod 231 is horizontal, that is, the axis of the plug rod 231 is perpendicular to the central axis of the chute 24. A first through groove is formed in the runner 21. One end of the first through groove communicates with one end of the chamber 25, and the other end of the first through groove communicates with one side of the chute 24, that is, the chamber 25 communicates with the chute 24 through the first through groove. A through hole 11 is formed in the side wall of the rotating shaft 1; the telescopic member is arranged in the chamber 25. The telescopic member has a telescopic end, and the output end of the telescopic member is connected to one end of the plug rod 231. The telescopic member is used to drive the plug rod 231 to move in the first through groove and the through hole 11. When the rotating shaft 1 and the runner 21 are coaxial, that is, when the rotating shaft 1 is located at the top of the chute 24, the telescopic member drives the plug rod 231 to move in the first through groove, so that one end of the plug rod 231 is inserted into the through hole 11. The insertion of the plug rod 231 into the through hole 11 connects the rotating shaft 1 and the runner 21 together, so that the rotation of the rotating shaft 1 can drive the runner 21 to rotate synchronously for ditch digging. When it is necessary to connect the rotating shaft 1 and the runner 21 together, it means that when the ditch digging spacing is adjusted, the ditch digging structure 2 belongs to the ditch digging structure 2 that has not been lifted. The spacing between the ditch digging structure 2 and the adjacent ditch digging structure 2 that has not been lifted is the ditch digging spacing required for planting forage grass, such as Figure 2 As shown, before ditch digging at this time, it is necessary to connect the rotating shaft 1 and the runner 21 of this ditch digging structure 2. During connection, the telescopic member is used to drive the plug rod 231 to move in the first through groove, so that one end of the plug rod 231 is inserted into the through hole 11. The insertion of the plug rod 231 into the through hole 11 connects the rotating shaft 1 and the runner 21 together. At the same time, when the adjusted ditch digging structure 2 needs to be lifted, it is also through the telescopic member to drive the plug rod 231 to move in the first through groove, as Figure 3 As shown, so that one end of the plug rod 231 is withdrawn from the through hole 11 and retracted, so that the rotating shaft 1 is separated from this ditch digging structure 2. At this time, the rotating shaft 1 can rotate and move in the chute 24 of this ditch digging structure 2. The runner 21 is lifted through the lifting component, so that the rotating shaft 1 moves to the bottom end of the chute 24, and the runner 21 is separated from the ground, so that ditch digging will not be carried out.

[0023] This embodiment provides a specific structure of the telescopic member, such as Figure 4As shown in the figure, further, the telescopic member includes: an electromagnet 232, a magnetic block 233, and a spring 234. The electromagnet 232 is disposed at one end of the chamber 25 away from the first through groove; the magnetic block 233 is disposed at one end of the insertion rod 231, and the electromagnet 232 is magnetically adsorbed to the magnetic block 233 after being energized; the spring 234 is disposed between the electromagnet 232 and the magnetic block 233, one end of the spring 234 is fixed to the electromagnet 232, and the other end of the spring 234 is fixed to the magnetic block 233. The spring 234 is made of a conductive material, such as iron. When it is necessary to retract one end of the insertion rod 231 from the through hole 11, the electromagnet 232 is energized so that the electromagnet 232 is magnetically adsorbed to the magnetic block 233, thereby compressing the spring 234 and driving the insertion rod 231 to move Figure 4 towards the left end, that is, towards the inside of the chamber 25, so that the insertion rod 231 is disengaged from the through hole 11; when it is necessary to insert the insertion rod 231 into the through hole 11, the electromagnet 232 is powered off, and the spring 234 returns to its natural state under the action of elastic force, driving the magnetic block 233 and the insertion rod 231 to move Figure 4 towards the right end, so that the insertion rod 231 is inserted into the through hole 11, and the rotating shaft 1 is connected to the rotating wheel 21.

[0024] In order to make the connection between the rotating shaft 1 and the rotating wheel 21 more stable, further, there are two through holes 11, and the two through holes 11 are symmetrically opened on both sides of the rotating shaft 1. There are two sets of fixing components 23, and the two sets of fixing components 23 correspond to the positions of the two through holes 11 respectively, that is, the two sets of fixing components 23 are located on both sides of the rotating shaft 1. When it is necessary to connect the rotating shaft 1 and the rotating wheel 21 together, the two insertion rods 231 are respectively inserted into the two through holes 11.

[0025] Embodiment 2 As a further improvement on the basis of Embodiment 1, further, the rotating wheel 21 is a hollow structure, that is, the rotating wheel 21 has only one outer shell. A housing is fixed to the inner wall of the rotating wheel 21, and the chamber 25 is located inside the housing. It is equivalent that the housing is a hollow groove body, and this groove body is fixed inside the rotating wheel 21, and the inside of the groove body is the chamber 25.

[0026] In order to better adjust the ditching structure 2 according to the type of forage, such as Figure 5As shown in the figure, further, a plurality of ditching columns 22 are inserted into the runner 21. A plurality of holes are provided in the side wall of the runner 21, and the ditching columns 22 are inserted into the holes, so that one end of the ditching column 22 is located inside the runner 21 and one end is located outside the runner 21. A threaded section 221 is provided in the circumferential direction of the ditching column 22, and the threaded section 221 is threadedly connected to the runner 21, that is, the threaded section 221 is threadedly connected to the hole wall. It further includes: a plurality of sets of transmission structures 5 corresponding to the plurality of runners 21 one by one. The transmission structure 5 has an output end and an input end. The input end of the transmission structure 5 is connected to the rotating shaft 1, and the output end of the transmission structure 5 is connected to the plurality of ditching columns 22. The transmission structure 5 is used to transmit the rotational movement of the rotating shaft 1 to the rotational movement of the plurality of ditching columns 22, that is, through the transmission structure 5, the plurality of ditching columns 22 rotate synchronously, extend or retract outward from the runner 21 synchronously, so as to realize the function of adjusting the extending length of the ditching column 22, facilitate adjusting the ditching depth according to different types of forage, further improve the working efficiency, and at the same time have a wider application range.

[0027] This embodiment provides a specific way of the transmission structure 5. Further, as Figure 5 shown, the transmission structure 5 includes: a first bevel gear 51, a telescopic rod 52, and a second bevel gear 53. The first bevel gear 51 is sleeved and fixed on the circumference of the rotating shaft 1, and the first bevel gear 51 is located inside the runner 21; a plurality of telescopic rods 52 are respectively arranged at one end of the plurality of ditching columns 22 located inside the runner 21. The telescopic rod 52 is a rod body with a telescopic function composed of multiple telescopic rods; a plurality of second bevel gears 53 are respectively sleeved and fixed on the circumferences of the plurality of telescopic rods 52, and the plurality of second bevel gears 53 are respectively meshed with the first bevel gear 51. The working principle of the transmission structure 5 in this embodiment: the rotation of the rotating shaft 1 drives the rotation of the first bevel gear 51, so that the plurality of second bevel gears 53 meshed with it rotate, driving the plurality of telescopic rods 52 and the plurality of ditching columns 22 to rotate. Because the threaded section 221 of the plurality of ditching columns 22 is connected to the runner 21, when the plurality of ditching columns 22 rotate, they can extend or retract relative to the runner 21, and will also drive the telescopic rods 52 to stretch or compress synchronously. In addition, an intermittent connection structure can be provided between the first bevel gear 51 and the circumference of the rotating shaft 1. When it is necessary to adjust the extending length of the ditching column 22, the first bevel gear 51 can be connected to the rotating shaft 1. After adjustment, in order not to affect the rotating shaft 1 driving the ditching structure 2 to ditch, the first bevel gear 51 can be disconnected from the rotating shaft 1, which can be realized by the fixing component 23 mentioned in the above embodiment 1, or other realizable structures in the prior art can also be used. Among them, the rotating shaft 1 can also be replaced by a separate driving motor. By connecting a rotating rod to the driving motor and sleeving the first bevel gear 51 on the rotating rod, it can also be realized.

[0028] Among them, the other structures of this embodiment are the same as those of Embodiment 1, except that it is an optimization of Embodiment 1.

[0029] Embodiment 3 As a further improvement on the basis of Embodiment 1, further, it further includes a bracket 4. When in use, the bracket 4 is connected to the vehicle body, so that the whole device can be driven to move when the vehicle body moves. The bracket 4 includes two first rods 41 arranged vertically and a second rod 42 arranged horizontally. The two ends of the second rod 42 are respectively fixed to the tops of the two first rods 41. The two ends of the rotating shaft 1 are respectively rotatably connected to the bottoms of the two first rods 41, and the rotational connection can be realized through bearings. The driving member can be arranged at the bottom of one of the first rods 41 and is connected to the end of the rotating shaft 1. In this embodiment, the whole device is supported and fixed by the bracket 4.

[0030] This embodiment provides a specific structure of a lifting assembly. Further, the lifting assembly includes: a sliding rod 31 and an electric telescopic rod 3. As Figure 6 shown, a ring groove 26 is formed on one side of the runner 21. The ring groove 26 is coaxially arranged with the runner 21. One end of the sliding rod 31 is slidably connected in the ring groove 26. The sliding rod 31 is L-shaped and includes a long rod arranged vertically and a short rod arranged at the bottom end of the long rod. The end of the short rod is clamped in the ring groove 26 and is slidably connected to the ring groove 26. The electric telescopic rod 3 is vertically arranged at the bottom of the second rod 42. The bottom end of the electric telescopic rod 3 is fixed to the other end of the sliding rod 31, and the free end of the electric telescopic rod 3 is connected to the top end of the long rod. When it is necessary to lift the unnecessary ditching structure 2, by controlling the electric telescopic rod 3 to contract, the sliding rod 31 connected thereto is driven to drive the runner 21 to move upward, so that the unnecessary ditching structure 2 can be lifted. In addition, for the ditching structure 2 that does not rise, when the rotating shaft 1 rotates, the runner 21 rotates synchronously, and at the same time, the sliding rod 31 slides in the ring groove 26, and the lifting assembly does not affect the rotation of the runner 21. Among them, the electric telescopic rod 3 can also be replaced with a hydraulic rod, an electric push rod, an electric cylinder or other structures with an electric contraction function.

[0031] Among them, the other structures of this embodiment are the same as those of Embodiment 1, only an optimization of Embodiment 1.

[0032] The advantages of the present invention are that when the device is in use, the runner rotates when the rotating shaft rotates for ditching. The device is provided with multiple groups of ditching structures and multiple groups of lifting assemblies. The lifting assembly can lift the runner of the ditching structure, so that the rotating shaft moves in the chute. When it is necessary to adjust the ditching spacing, the unnecessary runners can be lifted by regulation, and the spacing between the remaining adjacent runners can be adjusted to the required spacing, so that the ditching spacing can be adjusted according to different types of forage, improving the working efficiency. In addition, when different types of forage are planted in two adjacent ditches, the device is also applicable, and the ditching structure can be adjusted so that the spacing between two adjacent ditches is different, and the applicable range is wider.

[0033] The above are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any changes that can be conceived by those skilled in the art shall fall within the protection scope of the present invention.
