Description

Technical Field

[0001] This utility model relates to the field of seeders, specifically to a seeder with adjustable seeding rate. Background Technology

[0002] A seeder is a planting machine that sows crop seeds. Seeders used for a specific type or crop are often named after the crop, such as grain row seeders, corn hill seeders, cotton seeders, and pasture spreaders. In areas developing high-powered tractors, there is a trend towards further increasing the working width and operating speed of seeders, improving sowing quality under high-speed operation, and expanding their versatility and adaptability to different seeds, sowing rates, plant spacing, and various soil and ground conditions. At the same time, various combined operation machines and no-till seeders are continuing to develop. Furthermore, sowing methods are constantly being improved, such as the use of peristaltic pump seed dispensing in liquid seeding, which eliminates the impact of poor soil conditions on seed germination and allows for the simultaneous application of pesticides and fertilizers. Currently, existing seeders control the sowing rate at a fixed rate, making it difficult to adjust the sowing rate quickly and easily. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of the prior art by providing a seeder with an adjustable seeding rate, thereby solving the problem mentioned in the background art that the existing seeders have a fixed seeding rate during sowing and cannot easily and quickly adjust the seeding rate.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a seeder with adjustable seeding rate, comprising a rotating feeding structure, wherein an adjustable seeding rate control structure is fixedly installed below the rotating feeding structure;

[0005] The rotary unloading structure includes a frame body, and a bearing frame is welded and fixed to the bottom of the frame body. Wheels are rotatably mounted between the bearing frames via mounting shafts.

[0006] An installation frame is fixedly installed on one side of the upper part of the frame, and a discharge pipe is embedded through one side of the installation frame. At the same time, a feeding frame is fixedly installed directly below the discharge pipe.

[0007] By adopting the above technical solution, the seed discharge pipe is installed to achieve the function of seed discharge and transportation.

[0008] Preferably, the feeding frame has a through hole that is connected to the frame body, and a hollow cavity with a feeding port is fixedly installed below the frame body, while a sliding groove is provided through the front side of the hollow cavity.

[0009] By adopting the above technical solution, the material feeding frame is set up to serve as a material receiving and conveying mechanism.

[0010] Preferably, a feeding wheel is rotatably installed inside the hollow cavity via a connecting shaft, and baffles are fixedly installed on both sides of the feeding wheel. At the same time, a seed discharge pipe is embedded and installed through the hollow cavity to facilitate seed discharge.

[0011] By adopting the above technical solution, the material feeding wheel is set to achieve the function of rotating and feeding.

[0012] Preferably, a hydraulic rotary motor is fixedly installed on the outer wall of the hollow cavity, and the output end of the hydraulic rotary motor passes through the hollow cavity and is fixedly installed at one end of the connecting shaft.

[0013] By adopting the above technical solution, the hollow cavity is designed to facilitate opening and internal rotation installation.

[0014] Preferably, the adjustment and control structure includes a fixed mounting plate fixed to one side below, and a hydraulic telescopic rod is fixedly installed on one side of the fixed mounting plate. At the same time, an adjustment plate is fixedly installed at the output end of the hydraulic telescopic rod, and a recessed frame with a limit groove is fixedly installed on one side of the adjustment plate.

[0015] By adopting the above technical solution, the adjustable plate can achieve the function of force-driven adjustment.

[0016] Preferably, a rack is fixedly installed on the inner side of the concave frame, and the concave frame is matched with the sliding groove for sliding.

[0017] By adopting the above technical solution, the rack and pinion mechanism is used to adjust the insertion.

[0018] Compared with the prior art, the beneficial effects of this utility model are: this seeder with adjustable seeding rate...

[0019] (1) This case solves the problem that the existing seeder has a fixed seeding amount control during seeding and cannot easily and quickly adjust the seeding amount by setting up an adjustment control structure. After the hydraulic telescopic rod controls the concave frame to gradually adjust and slide inside the hollow cavity, the rack approaches the feeding wheel, and the seeds on the surface of the feeding wheel are controlled to be fed through the gap between the racks.

[0020] (2) By setting a rotating feeding structure, the problem of the existing seeder being unable to control the seed feeding speed is solved. When it is necessary to control the seed feeding speed, the rotation speed of the hydraulic rotary motor is controlled to change the rotation speed of the feeding wheel. By changing the rotation speed of the feeding wheel, the seed feeding speed is effectively controlled.

[0021] (3) By rotating the material feeding structure, the baffle plate is set in the material feeding structure, so as to solve the problem that when the seeds fall above the surface of the material feeding wheel, they are easy to fall through the sides of the material feeding wheel.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 This utility model provides a technical solution: a seeder with adjustable seeding rate, such as... Figure 1 , Figure 2 and Figure 3As shown, it includes a rotary feeding structure 1, which includes a frame body 101, and a bearing frame 102 is welded and fixed to the bottom of the frame body 101. Meanwhile, wheels 104 are rotatably mounted between the bearing frames 102 via mounting shafts 103.

[0031] Among them, the frame body 101, mounting shaft 103, wheel 104 and bearing frame 102 are all set with existing technical components, which effectively facilitates the suspension and movement of the frame body 101 when using existing technical components.

[0032] Furthermore, in the above scheme, an installation frame 105 is fixedly installed on one side of the upper part of the frame 101, and a discharge pipe 106 is embedded and installed through one side of the installation frame 105. At the same time, a feeding frame 107 is fixedly installed directly below the discharge pipe 106. A through hole 108 is opened in the feeding frame 107 and is connected through the frame 101. A hollow cavity 109 with a feed inlet 1010 is fixedly installed below the frame 101. At the same time, a sliding groove 1011 is opened through the front side of the hollow cavity 109.

[0033] Among them, there are multiple discharge pipes 106, and the number of discharge frames 107 and hollow cavities 109 is the same as the number of discharge pipes 106. When the above-mentioned components are arranged in the same number, the distribution of seeds can be effectively improved.

[0034] like Figure 4 As shown, in the above scheme, a feeding wheel 1012 is rotatably installed inside the hollow cavity 109 via a connecting shaft, and baffles 1013 are fixedly installed on both sides of the feeding wheel 1012. At the same time, a seed discharge pipe 1014 is embedded and installed directly below the hollow cavity 109 to facilitate seed discharge.

[0035] Among them, a set of baffles 1013 is provided on both sides of a single feeding wheel 1012. The baffles 1013 are used to effectively block the material on both sides and prevent the seeds from falling through the sides of the feeding wheel 1012.

[0036] Furthermore, a hydraulic rotary motor 1015 is fixedly installed on the outer wall of the hollow cavity 109, and the output end of the hydraulic rotary motor 1015 passes through the hollow cavity 109 and is fixedly installed at one end of the connecting shaft.

[0037] The hydraulic rotary motor 1015 adopts existing technical components. The use of existing technical components effectively facilitates the hydraulic connection between the hydraulic rotary motor 1015 and the hydraulic drive component through hydraulic pipes, thereby facilitating the normal operation and rotation adjustment of the hydraulic rotary motor 1015. At the same time, multiple hydraulic rotary motors 1015 are also provided, and the use of multiple hydraulic rotary motors 1015 effectively plays a role in control, drive and adjustment.

[0038] like Figure 5 and Figure 6 As shown, an adjustment control structure 2 is fixedly installed below the rotary feeding structure 1. The adjustment control structure 2 includes a fixed mounting plate 201 fixed to one side below, and a hydraulic telescopic rod 202 is fixedly installed on one side of the fixed mounting plate 201. At the same time, an adjustment plate 203 is fixedly installed at the output end of the hydraulic telescopic rod 202. A concave frame 204 with a limit groove 206 is fixedly installed on one side of the adjustment plate 203. A rack 205 is fixedly installed inside the concave frame 204, and the concave frame 204 slides in conjunction with the sliding groove 1011.

[0039] The aforementioned components constitute a drive adjustment structure. When the drive adjustment structure is formed by the aforementioned components, the sliding drive distance of the concave frame 204 and the rack 205 is effectively changed, thereby controlling the amount of seeds fed. Furthermore, the rack 205 is made of hard plastic material. When the aforementioned components are made of hard plastic material, it effectively avoids the situation where metal collisions are easily caused when the rack 205 comes into contact with the feeding wheel 1012. At the same time, the hydraulic telescopic rod 202 is also made of existing technical components. When the existing technical components are made, it is also effective in facilitating the hydraulic drive control of the hydraulic drive components.

[0040] In the above scheme, after the operator manually installs and connects the frame 101 to the drive unit with hydraulic drive components, the hydraulic pipe is then connected to the hydraulic rotary motor 1015 and the hydraulic telescopic rod 202. The operator then manually pours the seeds into the mounting frame 105, which is then conveyed through the discharge pipe 106 to the feeding frame 107. The seeds entering the feeding frame 107 fall into the hollow cavity 109 through the through hole 108 and the inlet 1010. Next, the operator uses the hydraulic drive components to control the operation of the hydraulic telescopic rod 202. When the hydraulic telescopic rod 202 is in operation, it drives the adjusting plate 203, the concave frame 204 and the rack 205 to slide and adjust gradually into the hollow cavity 109 along the sliding groove 1011. When the rack 205 gradually approaches the feeding wheel 1012, the operation of the hydraulic telescopic rod 202 is stopped. Then, the hydraulic rotary motor 1015 is controlled to operate again. When the hydraulic rotary motor 1015 is in operation, it drives the feeding wheel 1012 and the baffle plate 1013 to rotate synchronously under force. At this time, the seeds fall into the seed discharge pipe 1014 through the gap between the racks 205 for sowing.
