[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. 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 combination of one or more of the associated listed items.

[0036] 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, but not all. 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.

[0037] The seed tape seeder disclosed in the present application 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. Figure 1 Figure 2 The material storage and conveying mechanism comprises a discharging device 5 for releasing the 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.

[0038] 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.

[0039] The seed tape seeder disclosed in the present embodiment has a simple overall structure, small size, light weight, and single-row seed tape releasing and seeding function, which is suitable for small-scale planting in hilly or mountainous areas.

[0040] As shown in the drawings, the conveying device 6 comprises a pressing wheel set for rubbing the seed tape 4 to feed. The pressing wheel set comprises 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. Figure 3 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 each provided with a groove 64 for abutting the seed tape 4. The groove 64 is recessed from the circumferential surface to the center of the driving wheel 61 and the driven wheel 62. When the seed tape 4 passes between the driving wheel 61 and the driven wheel 62, the groove 64 plays a guiding and fixing role on the seed tape 4, avoiding the seed tape 4 from moving axially along the driving wheel 61 and the driven wheel 62 to cause disengagement from the pressing wheel set.

[0041] 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. Therefore, when the driving wheel 61 rotates, it will form a rubbing effect on the seed tape 4, thereby realizing the feeding of the seed tape 4.

[0042] ​Because the seed size of different crops is different, for example, the seed of green bean is small, while the seed of corn and garlic is large. The distance between the driving wheel 61 and the driven wheel 62 of the transmission device 6 is fixed, so different types of seed belt seeding machines are often needed for different crops, which obviously causes the waste of production materials and does not make the best use of things.

[0043] To solve this problem, in the embodiment, the driven wheel 62 can move away from or close to the driving wheel 61 to change the gap size between the driving wheel 61 and the driven wheel 62. The transmission device 5 includes a support 60 for fixing the compression wheel set, and 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 distance between the two can be changed to adapt to the passage of seed belts 4 of different sizes.

[0044] Specifically, as shown in Figure 4 The driven wheel 62 includes 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 to drive the driven wheel 62 to move in the direction close 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 belt 4, the transmission device 5 further comprises a reset element for providing the restoring force required for the driven wheel 62 to move 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 away from the driving wheel 61, the spring 63 is compressed, so the elastic force of the spring 63 ensures that the driving wheel 61 and the driven wheel 62 always maintain extrusion force to achieve the rubbing of the seed belt 4.

[0045] The material storage and conveying mechanism further comprises a guide groove 7 for conducting the seed belt 4 to the compression belt wheel 22, and the guide groove 6 extends from the transmission device 6 to the compression belt 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 belt wheel 22. The guide groove 7 plays a supporting and guiding role on the seed belt 4 between the transmission device 6 and the compression belt wheel 22, avoiding the shaking and breaking of the seed belt 4.

[0046] As shown in Figure 1 and Figure 2 The handrail 3 includes 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.

[0047] Due to the different terrain or user height difference, the height requirement of the handrail 3 is also different, for this, in the embodiment, the support rod 33 is hinged at one end with the push rod 31, and the other end is detachably connected with the rack 1, and the rack 1 is provided with a plurality of first mounting positions for adjusting the angle of the push rod 31 and the rack 1. Among them, the plurality of first mounting positions are a plurality of mounting holes 10 arranged on the rack 1, and the plurality of mounting holes 10 are distributed along a straight line along the direction from the walking wheel 21 to the pressing belt wheel 22. By replacing the support rod 33 with different mounting holes 10, the angle of the push rod 31 and the rack 1 can be changed.

[0048] In other embodiments of the present application, as shown in Figure 2 The support rod 33 is a plate structure, and a plurality of second mounting positions for fixed connection with the rack 1 are further arranged on the support rod 33. Specifically, the second mounting position includes a plurality of slot holes 330 arranged along the length direction of the support rod 33, and an opening is formed on one side of the slot hole 330 for the fixing bolt to pass through. The support rod 33 is also provided with a sliding groove 331 communicating with the plurality of slot holes, and the different slot holes 330 and the fixing bolt are matched by the sliding groove 331, so as to adjust the included angle between the push rod 31 and the rack 1, so as to adapt to the specific application environment.

[0049] Therefore, the transmission device 6 further comprises 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. By driving the driving wheel 61 to rotate through the first motor, and adjusting the rotating speed of the first motor through the first control unit, the adjustment of the feeding speed of the seed belt 4 can be realized.

[0050] In order to facilitate degradation and facilitate seed germination, the seed belt 4 is mostly made of paper belt woven by paper pulp, and is therefore easily broken by pulling. Therefore, in the embodiment, the feeding device 5 comprises 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. Among them, 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 is realized by controlling the rotation of the winding groove 51. The material storage and transportation mechanism further comprises a main control module, and the first control unit and the second control unit are respectively connected with the main control module in communication, for controlling the unwinding speed of the storage disc 50 to match the feeding speed of the seed belt 4.

[0051] The second motor drives the storage disc 50 to rotate, so that the surface of the seed belt 4 does not bear tension, avoiding the breakage of the seed belt 4 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, avoiding that the feeding speed of the transmission device 6 is too large to cause the seed belt 4 to be pulled, and the feeding speed is too small to cause the seed belt 4 to be accumulated.

[0052] 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 adjusting the rotating speeds 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.

[0053] The seed belt seeder disclosed in the present application is convenient to push forward by manpower through the handrails arranged on the frame, single walking wheels and pressing belt wheels are arranged at 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 material unwinding 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.
