Referring to fig. 1 and fig. 2 again, in the present embodiment, the sowing apparatus 200 specifically includes a feeding device 100 and two sowing devices 201.

In detail, in the present embodiment, the feeding device 100 includes a feeding housing 101, a feeding member 107, and a driving member.

The feeding shell 101 is substantially cylindrical, and the feeding shell 101 has a cylindrical hollow feeding chamber 102, wherein the feeding shell 101 may be a single shell or a structure in which an outer shell is sleeved outside an inner shell, and when the outer shell is sleeved outside the inner shell, the feeding chamber 102 is specifically disposed inside the inner shell. Meanwhile, the feeding shell 101 is further provided with a feeding hole 103 and two discharging holes 105, the feeding hole 103 and the two discharging holes 105 are both communicated with the feeding cavity 102, the feeding hole 103 is communicated with the storage box, so that materials in the storage box can be input into the feeding shell 101 through the feeding hole 103, and the two discharging holes 105 are both used for outputting the materials. Of course, in other embodiments, the shape of the feeding housing 101 may also be set to be square or other shapes, so as to ensure that the feeding operation is performed safely and orderly, which is not limited in this embodiment.

The feeding member 107 includes two feeding sections 109 rotatably disposed in the feeding housing 101, and the two feeding sections 109 are used for respectively conveying the material inputted from the feeding port 103 to the two discharge ports 105, so that the material inputted from the feeding port 103 can be outputted from the two discharge ports 105. The driving member is disposed on the feeding housing 101 and is configured to simultaneously drive the two feeding sections 109 to rotate relative to the feeding housing 101. The two spreading devices 201 are disposed in the feeding housing 101 and respectively communicated with the two discharge ports 105, so that when the driving member drives the two material conveying sections to move simultaneously, the two discharge ports 105 can respectively convey the materials to the corresponding spreading devices 201, thereby facilitating the spreading devices 201 to spread the materials. Through the arrangement, the feeding device 100 can drive the two feeding sections 109 to move simultaneously through one driving part to respectively feed materials to the two discharge ports 105, so that the transmission cost can be saved, the feeding cost can be saved, the sowing cost can be saved, and the overall operation cost can be saved. Meanwhile, two driving pieces are not needed to drive the two feeding sections 109 to move respectively, so that the control and maintenance cost can be saved correspondingly, and the operation cost is further reduced. In addition, the feeding of the two discharging ports 105 is realized by one driving member, and the feeding efficiency and the sowing efficiency can be ensured.

In detail, referring to fig. 1 and fig. 2 again, in the present embodiment, the sowing device 201 specifically includes a sowing housing 203, a sowing motor 205 and a sowing tray 207.

The scattering housing 203 is fixedly connected with the feeding housing 101, the scattering housing 203 is provided with a scattering channel communicated with the discharge port 105, the scattering motor 205 is arranged on the scattering housing 203, and the scattering disk 207 is movably arranged on the scattering housing 203 and is in transmission connection with the scattering motor 205 so as to rotate when the scattering motor 205 is started. When the material is spread, the material output from the discharge port 105 is conveyed to the spreading disk 207 through the spreading channel, and the spreading motor 205 is started to drive the spreading disk 207 to rotate, so that the material is spread conveniently.

Referring to fig. 1 and fig. 2 again, in the present embodiment, the two discharge ports 105 are respectively disposed at two opposite ends of the feeding housing 101, and the feed ports 103 are disposed in the circumferential direction of the feeding housing 101 and are approximately located at the middle position of the feeding housing 101, so that the positions of the two discharge ports 105 apart from the two ends are approximately the same, so as to sufficiently ensure that the material inputted from the feed ports 103 can be outputted from the two discharge ports 105 equally or uniformly, thereby further ensuring the spreading efficiency and quality. Correspondingly, two scattering devices 201 are respectively arranged at two ends of the feeding shell 101, and a scattering channel of each scattering device 201 is communicated with the discharge port 105 at a corresponding position. Through the arrangement, the driving piece drives the two material feeding sections 109 to feed materials in two opposite directions, so that the whole sowing equipment 200 is more compact in structure, and the sowing efficiency and quality can be fully guaranteed. Of course, in other embodiments, the positions of the feeding hole 103 and the discharging hole 105 may also be adjusted according to requirements, for example, both may be disposed in the circumferential direction of the feeding housing 101, and the description of this embodiment is omitted.

In detail, in order to ensure that the driving member can simultaneously drive the two feeding sections 109 to feed in two opposite directions, in this embodiment, each feeding section 109 includes a feeding shaft 111 and a helical blade 113 helically disposed on the circumference of the feeding shaft 111, the two feeding shafts 111 are coaxially disposed and coincide with the axis of the feeding housing 101, and each feeding shaft 111 extends from a position opposite to the feeding port 103 to the corresponding discharging port 105. The helical vanes 113 are oppositely rotated and each helical vane 113 is at least partially opposite the feed port 103. On one hand, the two feeding shafts 111 are coaxially arranged and are overlapped with the axial line of the feeding shell 101, so that the arrangement of a driving structure of a driving piece is facilitated, and the stability and the reliability of the feeding shafts 111 in the rotating process can be ensured, so that the driving stability is ensured, and the efficiency and the quality of material conveying are ensured; on the other hand, each helical blade 113 is at least partially opposite to the feeding hole 103, so that the structure of the whole feeding device 100 is more compact, and the material input from the feeding hole 103 can fall onto the two helical blades 113, thereby facilitating the transportation of the material to the corresponding discharging hole 105 when the corresponding feeding shaft 111 rotates, and facilitating the improvement of the stability and reliability of the discharging efficiency and the discharging process.

It should be noted that, in this embodiment, the lengths of the two feeding sections 109 are completely the same, the pitches, heights, and lengths of the helical blades 113 are the same, and the lengths of the portions of each helical blade 113 opposite to the feeding port 103 are the same, so that it can be fully ensured that the two feeding sections 109 can uniformly feed the materials to the two discharging ports 105, and further, the uniformity of the materials spread by the two spreading devices 201 can be fully ensured, so as to further improve the spreading quality.

Referring to fig. 1 and fig. 2 again, in the present embodiment, two feeding shafts 111 are connected to each other at positions opposite to the feeding ports 103 to form a shaft-like structure. And specifically, the two feeding shafts 111 may be integrally formed, and then the helical blades 113 having opposite rotation directions are respectively manufactured. Meanwhile, in the present embodiment, the driving member is disposed at an end of the feeding housing 101 through the motor mounting shell 125, so as to pass through the discharge hole 105 to be directly connected with an end of the shaft-like structure in a transmission manner. Through arranging the driving piece in the tip of pay-off casing 101, can be convenient for the driving piece to pass discharge gate 105 and be connected with the transmission of axle column structure to can utilize original discharge gate 105 to go the mounted position of rational arrangement transmission structure, thereby can improve the efficiency and the quality of installation, dismantlement and maintenance operation.

In detail, referring to fig. 2 again, in the embodiment, when the driving member is disposed at the end of the feeding housing 101, the driving member may be specifically configured to include a driving motor 115 and a first transmission assembly 116. The driving motor 115 includes a driving output shaft, and the driving output shaft may be a flat shaft. The first transmission assembly 116 is a transmission shaft, one end of the transmission shaft is in transmission connection with the driving output shaft, and the other end of the transmission shaft extends into the feeding housing 101 through any one of the two discharge ports 105 so as to be directly in transmission connection with the end of the shaft-like structure. Through setting up like this for the driving piece can with adjacent pay-off section 109 transmission fit, again because two pay-off section 109 lug connection cooperations or integrated into one piece, thereby can drive two pay-off section 109 movements simultaneously, again because the spiral direction of two helical blade 113 of pay-off section 109 is opposite, consequently can guarantee that the material can move to two opposite directions after the input from feed inlet 103, in order to export to corresponding scattering device 201 through corresponding discharge gate 105 respectively, thereby be convenient for spill from corresponding scattering dish 207, in order to accomplish the operation of scattering, fully guarantee to scatter efficiency and quality.

In addition, it should be noted that, in the present embodiment, when the rotation directions of the helical blades 113 of the two feeding sections 109 are opposite, and the two feeding shafts 111 are connected and arranged at a position opposite to the feeding port 103 to form a shaft-like structure, the driving member may also be arranged at a position adjacent to the middle part of the shaft-like structure to be in direct transmission connection with the middle part of the shaft-like structure.

In detail, when the driving member is disposed adjacent to the middle position of the shaft-like structure, the driving motor 115 may also be in transmission connection with the shaft-like structure through the first transmission assembly 116, in which case the first transmission assembly 116 may also be selected as a transmission shaft, and one end of the transmission shaft is in transmission connection with the driving output shaft, and the other end of the transmission shaft extends into the feeding housing 101 from the circumferential direction of the feeding housing 101 and is in direct transmission connection with the middle position of the shaft-like structure. The driving motor 115 is disposed near the middle of the shaft structure, so that the whole feeding device 100 is more compact, and the compactness of the whole sowing apparatus 200 is more conveniently ensured. Meanwhile, through the arrangement, the driving force of the driving motor 115 can be effectively transmitted to the whole shaft-shaped structure, so that the feeding efficiency is fully ensured, and the sowing efficiency and quality are improved.

Fig. 3 is a schematic structural diagram of a second seeding apparatus 200 according to the present embodiment at a first viewing angle; fig. 4 is a schematic structural diagram of a second seeding apparatus 200 according to the present embodiment in a second viewing angle. Referring to fig. 3 and fig. 4, when the spiral directions of the helical blades 113 of the two feeding sections 109 are opposite, the two feeding shafts 111 may also be disposed at intervals at positions opposite to the feeding port 103, that is, there is no direct connection and cooperation relationship between the two feeding shafts, and the two feeding shafts need to be in transmission cooperation through other structures. At this time, the driving member may be correspondingly configured to include the driving motor 115 and the second transmission assembly. The driving motor 115 is disposed adjacent to the connection position of the two feeding shafts 111, that is, substantially located in the middle of the feeding housing 101, and is respectively in transmission connection with the two feeding shafts 111 through the second transmission assembly, so as to directly drive the two feeding shafts 111 to rotate in the same direction, thereby realizing that the materials can be respectively conveyed to the two discharge ports 105 in two opposite directions, and further facilitating the broadcasting of the materials output by the corresponding discharge ports 105 by the broadcasting disc 207, so as to ensure the broadcasting efficiency and the broadcasting quality as well.

In detail, referring to fig. 3 and fig. 4 again, in this structure, the driving motor 115 includes a driving output shaft, the second transmission assembly includes a speed reducer 117, the speed reducer 117 is in transmission connection with the driving output shaft, the speed reducer 117 has two speed reducing output shafts coaxially arranged, and the two speed reducing output shafts are in transmission connection with the two feeding shafts 111 respectively, and are used for driving the two feeding shafts 111 to rotate in the same direction at the same time, so as to fully ensure that the material is respectively conveyed to the two discharging ports 105 in two opposite directions.

In addition, it should be noted that, in the present embodiment, the rotation directions of the helical blades 113 of the two feeding sections 109 may also be set to be the same. At this time, the two feeding shafts 111 may be disposed at a position opposite to the feeding port 103 at an interval, that is, they are not directly connected, but are in transmission fit through other transmission structures. The driving member may be correspondingly configured to include a driving motor 115 and a third transmission assembly, the driving motor 115 is disposed at a position adjacent to the feeding port 103, that is, at a position approximately in the middle of the feeding housing 101, and is respectively in transmission connection with the two feeding shafts 111 through the third transmission assembly, so as to drive the two feeding shafts 111 to rotate in opposite directions.

The third transmission assembly may specifically include a first transmission gear set, a speed reducer 117, a second transmission gear set, and a third transmission gear set. And, speed reducer 117 sets up in pay-off casing 101, and passes through first transmission gear group transmission connection with the drive output shaft of driving piece, and speed reducer 117 has two speed reduction output shafts, and one speed reduction output shaft passes through second transmission gear group transmission connection with one in two pay-off axles 111, and another speed reduction output shaft passes through third transmission gear group transmission connection with another in two pay-off axles 111. Through the setting of second drive gear group and second drive gear group for driving motor 115 when starting, the direction of rotation of two pay-off axles 111 is opposite, thereby makes even two helical blade 113 revolve to the same, also can drive the material to the pay-off mouth of two opposite direction motion to corresponding positions, thereby guarantees pay-off efficiency, in order to fully improve and to broadcast efficiency and quality.

It should be noted that, in this embodiment, the first transmission gear set, the second transmission gear set and the third transmission gear set all include a plurality of transmission gears in meshing transmission, and because the second transmission gear set and the third transmission gear set are respectively used for driving the two feeding shafts 111 to rotate in two opposite directions, the number of gears in the second transmission gear set can be larger by an odd number or smaller by an odd number relative to the number of the second transmission gear set, so as to fully ensure that the rotation directions of the two feeding shafts 111 are opposite, thereby further ensuring the spreading efficiency and quality.

Of course, in this embodiment, when the spiral blades 113 of the two feeding sections 109 have the same rotation direction, the driving motor 115 may also be disposed at the end of the feeding housing 101, and the two feeding shafts 111 are similarly disposed at a position opposite to the feeding port 103 and are in transmission connection through a fourth transmission assembly, which may be a gear assembly in meshing transmission. The driving motor 115 is specifically disposed at an end of the feeding housing 101 to directly drive the feeding shaft 111 at a corresponding position to rotate, and indirectly drive the other feeding shaft 111 to rotate reversely through the fourth transmission assembly. That is, in this scheme, the fourth transmission subassembly is used for the transmission to connect two feeding shafts 111 on the one hand, and on the other hand for guaranteeing that two feeding shafts 111 rotate around opposite direction to even guarantee that two helical blade 113 revolve to the same, also can be to opposite direction transported substance material, thereby guarantee the pay-off operating efficiency, with further improvement scattering efficiency and quality.

That is, in this embodiment, the two feeding shafts 111 of the two feeding sections 109 may be integrally formed to form an integral shaft-like structure, or may be arranged at intervals to be engaged with each other through other transmission structures. Meanwhile, the helical blades 113 of the two feeding sections 109 may be set to have the same or opposite rotation directions.
