Description

TECHNICAL FIELD

[0001] The utility model relates to agricultural implement technical field, concretely relates to a seeding machine. BACKGROUND

[0002] Rice, as the first big grain crop in China, is widely planted in China. More than 65% of the population in China eat rice as their staple food, which proves that rice plays an extremely important role in China's grain production. With the increasing demand for rice, automatic seedling raising equipment is now widely used to plant rice.

[0003] With the continuous development of seeding technology, the advantages and disadvantages of seeding technology reflect the overall technical level of a country's agricultural mechanization, and the seeding machine is the core component of agricultural mechanization. To achieve high-efficiency continuous precision seeding of the seeding machine, precision and uniform seeding of the seeding machine is required.

[0004] The existing seedling tray seeder can only perform precision seeding or dense seeding alone, and when the user has two needs, two seedling raising production lines or two different seeders need to be used, resulting in additional costs. And when using dense seeding for seedling raising, the user wants to increase the seeding speed, but the existing single seeder cannot achieve the corresponding seeding speed, and only increasing the number of seeders can achieve the desired seeding speed, which also increases the cost.

[0005] For example, Chinese patent document CN111802031A discloses a strip-sowing interchanging seeding device, which includes a sowing device and a strip-sowing device. The sowing device is installed on a machine frame, and the strip-sowing device is installed on the machine frame through a detachable connecting assembly. The sowing device is located above the strip-sowing device and plays the seed into the strip-sowing device. The strip-sowing interchanging seeding device can quickly switch between sowing and strip-sowing. However, when the device is used for sowing, it is equivalent to a common seeder and cannot adapt to high-speed seedling raising. When the seedling raising speed is high, multiple seeders need to be set up. SUMMARY

[0039] Embodiment

[0040] In combination Figures 1-3 The present embodiment provides a seeding machine, by setting two different types of seeding rollers on a seeding machine, according to the different seeding mode requirements, two different types of seeding rollers are used respectively, so that the switching of different seeding modes can be realized without increasing additional seeding equipment.

[0041] Specifically, referring to Figure 1The sowing machine of the embodiment comprises a hopper 1 and a shell 2. Since the sowing machine is placed on the seedling production line, the hopper 1 is used to receive seeds and deliver the seeds to the sowing roller arranged inside the shell 2, so the hopper 1 is arranged above the shell 2 and connected with the shell 2. In order to facilitate the hopper 1 to receive seeds, the upper end of the hopper 1 in the embodiment is large and gradually shrinks from top to bottom, and the lower end is small, which presents a funnel shape, so that the seeds can more smoothly fall onto the sowing roller arranged inside the shell 2. In the embodiment, the sowing roller is arranged inside the shell 2, but the driving connection structure of the sowing roller is arranged outside the shell 2. Such arrangement is to prevent the driving connection structure such as chain and gear arranged inside the shell 2 from interfering with sowing. Moreover, since the driving connection structure generally needs to be frequently lubricated, arranging the driving connection structure outside the shell 2 can make maintenance more convenient and avoid the lubricating oil and other substances from polluting the seeds. However, if the driving connection structure is directly exposed to the outside, dust and other impurities will affect the driving connection structure, which will easily damage the driving connection structure. Therefore, the protective cover 3 is arranged outside the driving connection structure in the embodiment, the protective cover 3 is connected with the outer side of the shell 2, the driving connection structure is covered in the space inside the protective cover 3, so as to protect the driving connection structure.

[0042] Referring to Figure 2 In the embodiment, two types of sowing rollers are arranged in the shell 2, at least one of which is a first type of sowing roller, and at least one of which is a second type of sowing roller. The sowing types of the first type of sowing roller and the second type of sowing roller are different. In the embodiment, the number of the two types of sowing rollers is more than or equal to one, but considering the floor area of the seedling production line and the space of the factory building, the sowing machine should not be too large. Therefore, in the sowing machine of the embodiment, only one of each of the two types of sowing rollers is arranged. One of them is a first sowing roller 51 (also called a precision sowing roller), which is a first type of sowing roller and is used for precision sowing (also called precision sowing, strip sowing, hole sowing, etc.). The other is a second sowing roller 52 (also called a dense sowing roller), which is a second type of sowing roller and is used for spreading seeds (also called dense sowing, broadcast sowing, etc.). In the embodiment, the first sowing roller 51 and the second sowing roller 52 are arranged separately and connected with the hopper 1.

[0043] In the embodiment, the first seeding roller 51 is a precision seeding roller, and the specific structure comprises a first roller body, and strip-shaped seed grooves are arranged along the circumferential direction of the roller body; or on the basis of the strip-shaped seed grooves, each strip-shaped seed groove is divided into a plurality of square seed grooves by a partition. The second seeding roller 52 is a close seeding roller comprising a second roller body, and strip-shaped seed grooves are arranged along the axial direction of the roller body. In the embodiment, when precision seeding is performed, only the first seeding roller 51 needs to be started to realize precision seeding. Since the required seeding amount for precision seeding is relatively small, the first seeding roller 51 performs seeding, and the second seeding roller 52 is not started and does not perform seeding. When close seeding is performed, the first seeding roller 51, although being a precision seeding roller, can also be used for close seeding, so that when seeding is performed, the first seeding roller 51 and the second seeding roller 52 rotate simultaneously, and the two rollers cooperate to seed the seedling tray to realize close seeding; or the first seeding roller 51 can be disassembled and replaced with the second type of seeding roller to perform close seeding, thereby accelerating the close seeding speed. In the embodiment, the first type of seeding roller and / or the second type of seeding roller is / are detachably installed in the housing 2.

[0044] Referring to Figure 3 In the embodiment, the first seeding roller 51 and the second seeding roller 52 of the seeding machine are respectively communicated with the hopper 1 through discharge channels. Since the second seeding roller 52 does not need to work when precision seeding is performed, a discharge plate 4 is arranged in the discharge channel connected between the hopper 1 and the second seeding roller 52, for controlling whether the discharge channel discharges. In addition, although the first seeding roller 51 can also perform close seeding, when the required seeding amount and speed of close seeding are not too large, the second seeding roller 52 can also complete the task, and at this time, the first seeding roller 51 does not work. Therefore, a discharge plate 4 is also arranged in the discharge channel connected between the hopper 1 and the first seeding roller 51. In the embodiment, according to the seeding mode in which the seeding machine is currently working, the opening and closing of the discharge plate 4 is controlled, and the opening and closing of the first seeding roller 51 and the second seeding roller 52 are matched, to realize time-sharing control of the two seeding types, that is, the precision seeding work and the close seeding work of the seeding machine are not simultaneously performed. In the embodiment, the first seeding roller 51 and the second seeding roller 52 are arranged side by side and symmetrically in the housing 2, which facilitates the control of the two seeding rollers when close seeding is performed, so that uniform close seeding of the seedling tray can be realized.

[0045] In the embodiment, in order to match the seeding of the two seeding rollers, the hopper 1 is designed. The hopper 1 in the embodiment comprises a storage box 11, and a partition 113 is arranged in the middle of the storage box 11. The partition 113 divides the storage box 11 into two spaces, that is, a first storage box 111 and a second storage box 112. The first storage box 111 is connected with the first seeding roller 51 through a first discharge channel 12, and the second storage box 112 is connected with the second seeding roller 52 through a second discharge channel 13.

[0046] In the embodiment, a discharge plate 4 is arranged in the first discharge channel 12 and the second discharge channel 13 respectively, and the discharge plate 4 comprises a baffle 44. In the embodiment, the baffle 44 is movably arranged in the discharge channel and extends to the outside of the discharge channel, and the end extending to the outside is connected with the screw rod 42, the screw rod 42 is connected with the fixing seat 43 through a threaded structure, and the fixing seat 43 is fixed on the seeding machine, which can be fixed on the hopper 1 or the shell 2. A rotating wheel 41 is arranged at the end of the screw rod 42, when the screw rod 42 is rotated through the rotating wheel 41, the screw rod 42 moves relative to the fixing seat 43, thereby driving the baffle 44 to move, the baffle 44 moves in the discharge channel, the opening size of the discharge channel can be controlled, and the discharge channel can also be closed, so that the first discharge channel 12 and / or the second discharge channel 13 are closed and the seeds will not fall down.

[0047] In the embodiment, a seed protection structure 7 is arranged at the side of the first seeding roller 51 and the second seeding roller 52, the first seed protection structure 71 is arranged at the side of the first seeding roller 51, and the second seed protection structure 72 is arranged at the side of the second seeding roller 52. The first seed protection structure 71 comprises a first belt 711, the first belt 711 is arranged between a first driving roller 712 and a first driven roller 713, and a first tensioning roller 714 is further arranged between the first driving roller 712 and the first driven roller 713 to tension the first belt 711. In the embodiment, the first driving roller 712 is connected with a driving structure, the driving structure drives the first driving roller 712 to rotate, the first driving roller 712 drives the first belt 711 to rotate, so that the first belt 711 rotates synchronously with the first seeding roller 51 and the rotating direction of the first belt 711 is opposite to that of the first seeding roller 51. The second seed protection structure 72 comprises a second belt 721, the second belt 721 is arranged between a second driving roller 722 and a second driven roller 723, and a second tensioning roller 724 is further arranged between the second driving roller 722 and the second driven roller 723 to tension the second belt 721. In the embodiment, the second driving roller 722 is connected with the driving structure, the driving structure drives the second driving roller 722 to rotate, the second driving roller 722 drives the second belt 721 to rotate, so that the second belt 721 rotates synchronously with the second seeding roller 52 and the rotating direction of the second belt 721 is opposite to that of the second seeding roller 52. In this way, the friction between the belt and the seeding roller is reduced, and the belt wear is reduced. In the embodiment, the first belt 711 is arranged in close contact with the surface of the first seeding roller 51, and the second belt 721 is arranged in close contact with the surface of the second seeding roller 52, so as to protect the seeds from falling off from the groove on the seeding roller. In the embodiment, a seed cleaning brush 6 is further arranged at the side of the seeding roller, and the brush 6 is in contact with the surface of the seeding roller. The brush 6 comprises a first brush 61 and a second brush 62, the first brush 61 is arranged at the side of the first seeding roller 51, and the second brush 62 is arranged at the side of the second seeding roller 52 to clean the excess seeds.

[0048] In the embodiment, each seeding roller is connected with a corresponding servo motor, and the servo motor is used to drive the seeding roller to rotate. The specific connection mode is that the seeding roller is connected with the servo motor through a driving connection structure. The end of the first seeding roller 51 is a driving shaft, which extends out of the shell 2. A gear, a chain or a belt transmission member can be connected on the driving shaft. The servo motor includes a first motor 81 and a second motor 82. The first motor 81 is arranged in the shell 2, and an output shaft of the first motor 81 extends out of the shell 2. A gear, a chain or a belt transmission member is arranged on the output shaft. The first motor 81 is connected with the first seeding roller 51 through the transmission member. The second motor 82 is connected with the second seeding roller 52 in the same way as the first motor 81 is connected with the first seeding roller 51.

[0049] In the embodiment, the first driving roller 712 in the first seed protection structure 71 can be driven by a separate driving motor or by the first motor 81. In this case, several transmission members are arranged on the output shaft of the first motor 81, and the transmission members are connected with the first seeding roller 51 and the first driving roller 712, respectively. The first brush 61 can also be driven by a separate driving motor or by the first motor 81. When the first motor 81 drives the first seeding roller 51, the first brush 61 and the first driving roller 712 at the same time, the synchronous rotation of the three components can be realized without adjustment. The second seeding roller 52, the second brush 62 and the second driving roller 722 are connected with the second motor 82 in the same way as described above.

[0050] The above description of the utility model and its embodiments is illustrative rather than restrictive, and the embodiments shown in the drawings are only one of the embodiments of the utility model, and the actual structure is not limited to this.
