The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The use of the terms "and / or" includes a set of one or more of the associated listed items.

[0037] In addition, the technical features involved in the different embodiments of the invention described below can be combined with each other as long as there is no conflict. Obviously, the described embodiments are part of the embodiments of the invention, not all of them. Based on the described embodiments of the invention, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the invention.

[0038] The seed tape seeder disclosed in the present application, as shown in FIG. 1 and FIG. 2, comprises a frame 1, a walking wheel 21 and a pressing wheel 22 arranged at two ends of the frame 1 respectively, a material storage and conveying mechanism fixed to the frame 1, and a handrail 3 fixed to the frame 1. The material storage and conveying mechanism comprises a discharging device 5 for releasing a seed tape 4 and a conveying device 6 for controlling the feeding of the seed tape 4 between the pressing wheel 22 and the discharging device 5. The walking wheel 21 and the pressing wheel 22 are arranged at two ends of the frame 1 respectively, which facilitates single-row seeding.

[0039] In other embodiments of the present application, the pressing wheel 22 can also be arranged in multiple numbers and correspondingly arranged with the material storage and conveying mechanism, so as to realize multi-row seeding. The walking wheel 21 can also be arranged in multiple numbers according to the stress condition of the frame 1.

[0040] The seed tape seeder disclosed in the present embodiment is convenient to be pushed forward by manpower through the arrangement of the handrail 3 on the frame 1, and the single walking wheel 21 and the single pressing wheel 22 are arranged at two ends of the frame 1 respectively, which reduces the volume of the equipment and realizes single-row seeding. The material storage and conveying mechanism realizes the discharging and conveying of the seed tape 4. The seed tape seeder has simple overall structure, small size and light weight, and has the function of single-row releasing seed tape, which is suitable for small-scale planting in hilly or mountainous areas.

[0041] As shown in FIG. 3, the conveying device 6 comprises a pressing wheel set for rubbing the feeding of the seed tape 4, the pressing wheel set comprising a driving wheel 61 and a driven wheel 62 matched with the driving wheel 61, and the seed tape 4 passes between the driving wheel 61 and the driven wheel 62. The driving wheel 61 and the driven wheel 62 are arranged in pairs, and the pressing wheel set comprises multiple pairs of driving wheels 61 and driven wheels 62. The driving wheel 61 and the driven wheel 62 are oppositely arranged, and the circumferential surfaces of the driving wheel 61 and the driven wheel 62 are both provided with grooves 64 for abutting the seed tape 4. The grooves 64 are recessed from the circumferential surfaces of the driving wheel 61 and the driven wheel 62 towards the center, and when the seed tape 4 passes between the driving wheel 61 and the driven wheel 62, the grooves 64 play a guiding and fixing role on the seed tape 4, avoiding the seed tape 4 moving axially along the driving wheel 61 and the driven wheel 62 to cause the seed tape 4 to be separated from the pressing wheel set.

[0042] When the seed tape 4 passes between the driving wheel 61 and the driven wheel 62, it will be subjected to a certain extrusion force, so that when the driving wheel 61 rotates, a rubbing effect will be formed on the seed tape 4, thereby realizing the feeding of the seed tape 4.

[0043] Since the sizes of seeds of different crops are different, for example, the seeds of mung beans are small, while the seeds of corn and garlic are large. The distance between the driving wheel 61 and the driven wheel 62 of the conveying device 6 is fixed, so that different types of seed tape seeders are often needed for different crops, which obviously causes waste of production materials and does not make the best use of materials.

[0044] To solve this problem, in the embodiment, the driven wheel 62 can move in the direction away from or close to the driving wheel 61, for changing the gap size between the driving wheel 61 and the driven wheel 62. Wherein, the transmission device 5 comprises a support 60 for fixing the compression wheel set, the driving wheel 21 is fixedly arranged on the support 60, and the driven wheel 62 is movably connected to the support 60. In this way, by adjusting the position of the driven wheel 62 relative to the driving wheel 61, the gap between the two can be changed, so as to adapt to the seed tape 4 of different sizes.

[0045] Specifically, as shown in FIG. 4, the driven wheel 62 comprises a wheel body 620, a wheel frame 621 for fixing the wheel body 620, and a telescopic rod 622 fixedly connected with the wheel frame 621, and the telescopic rod 622 is movably connected to the support 60. The telescopic rod 622 can move relative to the support 60, thereby driving the driven wheel 62 to move in the direction adjacent to or away from the driving wheel 61. In order to ensure that the driven wheel 62 and the driving wheel 61 can generate extrusion force on the seed tape 4, the transmission device 5 further comprises a reset element for providing the required restoring force for the driven wheel 62 to move in the direction close to the driving wheel 61. The reset element is a spring 63 sleeved on the telescopic rod 622. When the driven wheel 62 moves in the direction away from the driving wheel 61, the spring 63 is compressed, so that the elastic force of the spring 63 ensures that the driving wheel 61 and the driven wheel 62 always maintain extrusion force, thereby achieving the rubbing of the seed tape 4.

[0046] The material storage and conveying mechanism further comprises a guide groove 7 for conducting the seed tape 4 to the compression wheel 22, and the guide groove 6 extends from the transmission device 6 to the compression wheel 22. Specifically, one end of the guide groove 7 is fixedly connected with the support 50, and the other end extends along the bottom of the compression wheel 22. The guide groove 7 plays a supporting and guiding role on the seed tape 4 between the transmission device 6 and the compression wheel 22, avoiding the shaking and breaking of the seed tape 4.

[0047] As shown in FIG. 1 and FIG. 2, the handrail 3 comprises a push rod 31 rotatably connected with the frame 1, an operating rod 32 arranged at the end of the push rod 31, and a support rod 33 connecting the frame 1 and the push rod 31. In this way, the push rod 31, the frame 1 and the support rod 33 form a triangle, increasing the stability of the connection between the handrail 3 and the frame 1.

[0048] Due to the difference in terrain or the difference in height of the user, the height requirement of the handrail 3 is also different. For this purpose, in the embodiment, one end of the support rod 33 is hingedly connected with the push rod 31, and the other end is detachably connected with the frame 1, and the frame 1 is provided with a plurality of first mounting positions for adjusting the angle between the push rod 31 and the frame 1. Wherein, the plurality of first mounting positions are specifically a plurality of mounting holes 10 arranged on the frame 1, and the plurality of mounting holes 10 are distributed along a straight line in the direction from the walking wheel 21 to the compression wheel 22. By replacing the support rod 33 matched with different mounting holes 10, the angle between the push rod 31 and the frame 1 can be changed.

[0049] In other embodiments of the present application, as shown in FIG. 2, the support rod 33 is a plate structure, and a plurality of second mounting positions for fixedly connecting with the rack 1 are further arranged on the support rod 33. Specifically, the second mounting positions include a plurality of slot holes 330 arranged along the length direction of the support rod 33, and an opening through which a fixing bolt can pass is arranged on one side of each slot hole 330. A sliding groove 331 in communication with the plurality of slot holes is further arranged on the support rod 33, and the sliding groove 331 facilitates replacement of different slot holes 330 matched with the fixing bolt, so as to adjust the included angle between the push rod 31 and the rack 1 to adapt to specific application environments.

[0050] Therefore, the conveying device 6 further includes a first motor for driving the driving wheel 61 to rotate, and a first control unit for controlling the rotating speed of the first motor. The first motor drives the driving wheel 61 to rotate, and the first control unit adjusts the rotating speed of the first motor, so as to realize the adjustment of the feeding speed of the seed belt 4.

[0051] In order to facilitate degradation and seed germination, the seed belt 4 is usually made of a paper belt woven by paper pulp, and is easily broken under strong pulling. Therefore, in the present embodiment, the feeding device 5 includes a storage disc 50 for winding the seed belt 4, a second motor for driving the storage disc 50 to rotate, and a second control unit for controlling the rotating speed of the second motor. The storage disc 50 is provided with a winding groove 51 for winding the seed belt 4, and the winding and unwinding of the seed belt 4 are realized by controlling the rotation of the winding groove 51. The material storage and transportation mechanism further includes a main control module, and the first control unit and the second control unit are respectively in communication connection with the main control module, so as to control the unwinding speed of the storage disc 50 to match the feeding speed of the seed belt 4.

[0052] The second motor drives the storage disc 50 to rotate, so that the surface of the seed belt 4 does not bear tension, and the seed belt 4 is prevented from being broken in the feeding process. The main control module controls the first control unit and the second control unit, so that the unwinding speed of the storage disc 50 matches the speed of the seed belt 4 rubbed by the driving wheel 61, and the feeding speed of the conveying device 6 is prevented from being too large to cause the seed belt 4 to be pulled, or too small to cause the seed belt 4 to be accumulated.

[0053] Specifically, the material storage and transportation mechanism further comprises a sensing device for detecting the rotating speed of the pressing belt wheel 22, the sensing device being in communication connection with the master control module, and the master control module adjusts the rotating speed of the first motor and the second motor according to the rotating speed of the pressing belt wheel 22, so as to match the unwinding speed of the seed belt, the feeding speed of the seed belt and the advancing speed of the pressing belt wheel. The unwinding speed of the seed belt 4 is the speed at which the seed belt 4 is unwound from the storage disc 50, the feeding speed of the seed belt 4 is the linear speed of the outer edge of the driving wheel 61, and the advancing speed of the pressing belt wheel 22 is the linear speed of the outer edge of the pressing belt wheel 22. The master control module calculates the linear speed of the outer edge of the pressing belt wheel 22 according to the rotating speed of the pressing belt wheel 22, and then adjusts the unwinding speed of the storage disc 50 by adjusting the rotating speed of the first motor, and adjusts the linear speed of the outer edge of the driving wheel 61 by adjusting the rotating speed of the second motor, so as to match the three.

[0054] The seed belt seeder disclosed in the present application is convenient to push forward by manpower through the handrails arranged on the frame, a single walking wheel and a pressing belt wheel are arranged at the two ends of the frame respectively, the volume of the equipment is reduced, single-row seeding is realized, the material storage and transportation mechanism realizes the release and transmission of the seed belt, the seed belt seeder has simple overall structure, small size and light weight, has the seeding function of single-row release of the seed belt, and is suitable for small-scale planting in hilly or mountainous areas.
