[0043] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] The embodiment of the present application provides a seeder, which can solve the problem that the seeder cannot effectively control the number of seeds sown in a certain area.

[0045] Reference Figure 1 to Figure 3 , is a seed drill, comprising:

[0046] Mobile frame 1;

[0047] A lower hopper 2, which is fixed on the moving frame 1 and is provided with a feed inlet and a discharge outlet;

[0048] A discharge plate 3 is slidably disposed on the discharge port side of the discharge hopper 2 along a first direction and covers the discharge port, and is provided with a discharge hole 30 smaller than the discharge port, so that when the discharge plate 3 reciprocates in the first direction, the discharge port is docked / closed through the discharge hole 30;

[0049] A driving device 4 is provided with a material removal transmission assembly between the driving device 4 and the material removal plate 3 to drive the material removal plate 3 to reciprocate in the first direction.

[0050] Among them, the lower hopper 2 installed on the mobile frame 1 will be used to hold the seeds to be sown, and the lower plate 3 is used to slide back and forth driven by the driving device 4 during the movement of the mobile frame 1. At this time, the discharge port will be closed or opened during the reciprocating sliding process through the lower hole 30 thereon. For the discharge port in the open state, the seeds in the lower hopper 2 can be directly dropped onto the surface soil through the lower hole 30 to complete the sowing, so as to effectively ensure that the set number of seeds can be sown in the sowing area in a single sowing process.

[0051] Further, in some preferred embodiments, a plurality of the discharge holes 30 are provided on the discharge plate 3 along the first direction, and intervals between the discharge holes 30 are greater than the length of the discharge port in the first direction.

[0052] Specifically, by setting a plurality of feeding holes 30 in the sliding direction of the feeding plate 3, the feeding plate 3 can discharge seeds at intervals for multiple times during the unidirectional sliding process, thereby further improving the sowing efficiency of the seeder in actual use. In this embodiment, preferably two feeding holes 30 are set, and the interval between the two feeding holes 30 is larger than the discharge port, so that when the feeding plate 3 reciprocates in the first direction, the two feeding holes 30 will be aligned with the discharge port in turn to sow seeds at intervals.

[0053] Further, see Figure 4 In this embodiment, in order to ensure that the seeds passing through the feeding hole 30 can be accurately sown to the designated area below, a discharge hopper 21 for guiding the seeds to fall is provided below the feeding plate 3. The top opening of the discharge hopper 21 is in sliding contact with the bottom surface of the feeding plate 3 and is vertically opposite to the discharge port, and is used to receive the seeds falling from the feeding hole 30. The bottom opening of the discharge hopper 21 extends vertically downward to near the ground surface, so as to smoothly guide the seeds to the surface soil.

[0054] Furthermore, in some preferred embodiments, a plurality of lower hoppers 2 are arranged at intervals in the horizontal and vertical directions of the moving direction of the moving frame 1 .

[0055] Specifically, refer to Figure 3 and Figure 4 , a mounting frame 10 for horizontal extension is provided on the mobile frame 1, and the extension direction is perpendicular to the moving direction of the mobile frame 1, and multiple feed hoppers 2 are installed on the mounting frame 10 at intervals, and are detachably bolted and fixed to the mounting frame 10. At the same time, in some embodiments, the feed plates 3 of multiple feed hoppers 2 can be respectively connected to the driving device 4 through independent feed transmission assemblies to achieve a one-to-one transmission effect; in some embodiments, one feed plate 3 can be connected to the driving device 4 through a feed transmission assembly, and the remaining feed plates 3 can be connected to the feed plate 3 to achieve a one-to-many transmission effect; and in this embodiment, it is preferred to set a group of feed transmission assemblies, and the feed transmission assembly includes a transmission rod 31, and the feed plates 3 of multiple feed hoppers 2 are fixedly connected to the same transmission rod 31. After one side of the transmission rod 31 is further connected to the driving device 4, the feed transmission assembly drives multiple feed plates 3 to slide back and forth at the same time.

[0056] Further, see Figure 2 and Figure 5 In some preferred embodiments, the material feeding transmission assembly further comprises:

[0057] A rotating cam 32 is rotatably disposed on the moving frame 1, and a rotating shaft thereof is transmission-connected to the driving device 4 so as to drive the rotating cam 32 to rotate through the driving device 4;

[0058] The transmission connecting rod 33 has one end rotatably connected to the eccentric point of the rotating cam 32 and a rotation axis parallel to the rotation axis of the rotating cam 32 , and the other end rotatably connected to the transmission rod 31 .

[0059] Specifically, a moving groove 11 is provided on the moving frame 1 for the transmission rod 31 to reciprocate in the first direction, and one end of the transmission rod 31 passes through the moving groove 11. In this embodiment, the first direction is consistent with the traveling direction of the planter. One end of the transmission connecting rod 33 is rotatably sleeved on the end of the transmission rod 31, and the other end is rotatably connected with the rotating cam 32 by rotating the rotating shaft set on the eccentric point of the rotating cam 32. The rotating axis is parallel to the axis of the rotating cam 32. Therefore, when the rotating cam 32 rotates, the transmission rod 31 will be driven to slide back and forth in the moving groove 11 through the transmission connecting rod 33, thereby driving the blanking plate 3 to slide back and forth in the first direction.

[0060] Further, see Figure 6 In some preferred embodiments, the seeder further comprises:

[0061] The groove pressing wheel 5 is rotatably arranged on the moving frame 1 and corresponds to the lower hopper 2 one by one. It is located downstream of the corresponding lower hopper 2 in the traveling direction and comprises a wheel body and a groove pressing protrusion 50 arranged on the circumferential surface of the wheel body.

[0062] Specifically, the mobile frame 1 is rotatably arranged downstream of the discharge hopper 2 in the traveling direction and is provided with a front mounting shaft 12 for mounting the groove pressing wheel 5. The front mounting shaft 12 is vertical and perpendicular to the traveling direction, and a plurality of groove pressing wheels 5 are fixedly mounted on the front mounting shaft 12. The groove pressing wheel 5 comprises a wheel body with a smaller diameter and a groove pressing protrusion 50 arranged on the circumference of the wheel body. The groove pressing protrusion 50 is specifically arranged at the center of the circumference of the wheel body, and the axial width of the groove pressing protrusion 50 is smaller than that of the wheel body, so that it can press grooves on the surface soil during the rolling of the groove pressing wheel. At the same time, the plurality of groove pressing protrusions 50 correspond to the plurality of discharge hoppers 2 in the traveling direction one by one, which is specifically reflected in that the groove pressing protrusions 50 on the groove pressing wheel 5 and the corresponding discharge holes 30 of the discharge plate 3 are in the same traveling direction. Furthermore, the groove pressing wheel 5 can use the groove pressing protrusion 50 to form grooves for placing seeds on the surface soil during the movement of the seeder, and then the lower hopper 2 will sow seeds in the grooves at intervals and in a controlled amount, ultimately further improving the sowing effect of the seeder in actual use.

[0063] Furthermore, in some preferred embodiments, the grooved wheel 5 is transmission-connected to the driving device 4 .

[0064] With this arrangement, the driving device 4 can simultaneously drive the groove pressing wheel 5 to rotate and the unloading plate 3 to unload materials when started, thereby actively driving the seeder to move while ensuring that the unloading frequency and the moving distance of the seeder are coordinated with each other, which can further achieve accurate control of the sowing spacing when sowing seeds.

[0065] Further, see Figure 6 In this embodiment, a traveling wheel 6 is also provided on the moving frame 1, which is rotatably mounted on the moving frame 1, and a traveling transmission component is provided between the traveling wheel 6 and the driving device 4.

[0066] Specifically, the mobile frame 1 is rotatably installed with a rear mounting shaft 13 on the side of the lower hopper 2 away from the groove pressing wheel 5. The rear mounting shaft 13 is horizontal and parallel to the front mounting shaft 12. The traveling wheel 6 is fixedly installed on the rear mounting shaft 13 and corresponds one-to-one with the groove pressing wheel 5. The diameter of the traveling wheel 6 is consistent with that of the groove pressing wheel 5, and the circumferential width of the wheel body of the traveling wheel 6 is not less than the circumferential width of the wheel body of the groove pressing wheel 5.

[0067] On the other hand, a transmission assembly is provided between the traveling wheel 6 and the driving device 4, and the groove pressing wheel 5 is also connected to the driving device 4, so that the driving device 4 can simultaneously drive the traveling wheel 6, the groove pressing wheel 5 and the blanking plate 3 to work. It can be understood that the traveling wheel 6 and the groove pressing wheel 5 should have a consistent rolling speed under the drive of the driving device 4 to ensure that the seeder can move smoothly in the traveling direction.

[0068] Specifically, refer to Figure 2 As for the transmission mode between the driving device 4 and the traveling wheel 6, the groove pressing wheel 5 and the blanking plate 3 in the above content, in this embodiment, a chain transmission assembly (i.e., a traveling transmission assembly) is arranged between the power output shaft of the driving device 4 and the rear mounting shaft 13 of the traveling wheel 6, a chain transmission assembly is arranged between the rear mounting shaft 13 and the front mounting shaft 12, and a chain transmission assembly is arranged between the rear mounting shaft 13 and the blanking plate 3 (i.e., a chain transmission assembly is arranged between the rear mounting shaft 13 and the rotating cam 32, i.e., a blanking transmission assembly) is achieved.

[0069] In addition, in order to prevent the groove pressing wheels 5 and the traveling wheels 6 provided in this embodiment from sinking too deeply into the soil when they move on some soils with too soft texture, anti-sinking cylinders 7 for increasing the soil pressing area are provided between some groove pressing wheels 5 and some traveling wheels 6. The two ends of the anti-sinking cylinder 7 are respectively connected to the groove pressing wheels 5 / traveling wheels on both sides, and the diameter thereof is smaller than that of the groove pressing wheels 5 and the traveling wheels 6.

[0070] Further, see Figure 4In some preferred embodiments, an opening and closing plate 20 is slidably provided on the side wall of the lower hopper 2 between the feed port and the discharge port, and the opening and closing plate 20 is used to cut off / connect the lower hopper 2 when sliding.

[0071] In this way, by setting the opening and closing plate 20, when it is not necessary to sow seeds but the seeder needs to be moved, the opening and closing plate 20 can be manually slid to cut off the lower hopper 2, preventing the seeds in the lower hopper 2 from further entering the lower hole 30 from the discharge port. At this time, when the seeder is in the process of moving (that is, the lower plate 3 is in the process of reciprocating sliding), seeds will no longer be sown.

[0072] Further, see Figure 4 and Figure 6 In some preferred embodiments, the seeder further comprises:

[0073] The gathering member 8 is fixed on the moving frame 1 and corresponds one-to-one to the lower hopper 2. It is located upstream of the lower hopper 2 in the traveling direction and below the lower hopper 2 in the height direction. It includes two gathering plates arranged at intervals. The spacing between the two gathering plates gradually increases in the traveling direction, and the minimum spacing between the two gathering plates is equal to the groove pressing protrusion 50 and is aligned with the groove pressing protrusion 50 in the traveling direction.

[0074] With such arrangement, the loose soil on both sides of the soil groove formed by the groove pressing protrusion 50 can be gathered through the two gathering plates, and then after the lower hopper 2 sows the seeds into the soil groove, the gathering piece 8 can gather the soil to cover the seeds, thereby further improving the effect of the seeder during use and reducing the difficulty of seed sowing.
