Description

Technical Field

[0001] This utility model relates to mechanical equipment for seedling tray breeding and sowing, belonging to the field of agricultural machinery technology, specifically to a self-propelled seedling tray breeding and sowing machine. Background Technology

[0002] Existing seedling tray seeders, such as the self-propelled seedling tray seeder disclosed in CN 209527137 U, include a frame, a transmission mechanism, and a walking mechanism. A handle is mounted at one end of the frame, and a guide plate is mounted at the other end. Between the handle and the guide plate, a tray feeding track, a bottom soil sowing mechanism, a sowing mechanism, and a covering soil sowing mechanism are sequentially mounted on the frame. The tray feeding track is located inside the frame. Above the tray feeding track, the bottom soil sowing mechanism, the sowing mechanism, and the covering soil sowing mechanism are sequentially mounted. The walking mechanism is mounted below the frame. The transmission mechanism is connected to the tray feeding track, the bottom soil sowing mechanism, and the covering soil sowing mechanism. The walking mechanism includes two drive wheels connected by a drive wheel axle, two support wheels connected by a support wheel axle, two tension wheels connected by a tension wheel axle, and two walking tracks fitted over the drive wheels, support wheels, and tension wheels. A sprocket on the output shaft of a second motor drives a sprocket on the drive wheel axle via a chain, which in turn drives the drive wheel axle and the tension wheel axle. A clutch is added between the second motor and the drive shaft. The sprocket on the second motor drives the sprocket on the clutch via a chain, and the sprocket on the clutch is connected to the sprocket on the drive shaft via a chain. This split structure makes maintenance and replacement convenient and cost-effective. Furthermore, the walking mechanism and transmission mechanism are driven by two motors, allowing for synchronization. Although the document describes the support rollers, it does not specify how to drive them to lift the frame for labor-saving purposes. Based on this, this application designs a novel self-propelled seedling tray seeder, whose support rollers can lift the frame using a manual, labor-saving turning and quick-moving mechanism with large and small gears, thus achieving labor-saving operation. Summary of the Invention

[0003] This utility model addresses the problems existing in the prior art by proposing a self-propelled seedling tray seeding machine. Due to the difference in diameter between the large and small wheel systems, the machine forms an angle, resulting in a smooth and uniform lower plate and more reliable movement. The support rollers are located inside the side frame, solving the problem of wasting land due to their external placement. Furthermore, during use, the small gear drives the large and small gears, which in turn drive the support rollers, making it easier to lift the frame.

[0004] The technical solution adopted by this utility model is as follows: a self-propelled seedling tray seeding machine, including a frame and a small wheel set and a large wheel set installed on the frame. The small wheel set and the large wheel set are spaced apart in the front-back direction. The frame has side frames on both sides. The small wheel set and the large wheel set are rotatably installed on the side frames. A small gear is rotatably installed on the outer end face of the side frame. The small gear meshes with the large gear. The large gear is fixed on the gear shaft. The gear shaft is rotatably connected to the side frame. The gear shaft is fixedly connected to the wheel axle through a connector. A support roller is rotatably installed on the wheel axle. The support roller is located in the middle between the two side frames.

[0005] Based on the above scheme, as a preferred option, there are two support rollers, which are rotatably mounted at both ends of the axle. The middle part of the axle is fixedly connected to the middle part of the gear shaft through a connector, and the two ends of the gear shaft are rotatably connected to two side frames respectively.

[0006] Based on the above scheme, as a preferred embodiment, the pinion is rotatably mounted on the side frame via a pinion shaft, and the end of the pinion shaft has a polygonal groove or a polygonal extension.

[0007] It also includes a crank that can be inserted into a polygonal groove or fitted onto a polygonal extension at one end.

[0008] Based on the above solution, as a preferred option, the upper end of the crank handle is fitted with a rubber sleeve to form a hand grip, and the hand grip is uneven.

[0009] Based on the above scheme, as a preferred option, a tray-swinging frame is fixedly installed on the side of the frame near the handle. The tray-swinging frame includes an upper frame, a lower frame, and a side frame formed by several square tubes fixedly connected together. The side frame is fixed on the side frame, and the upper frame and the lower frame are fixedly connected to the side frame. When the large wheel set and the small wheel set are in contact with the ground, the upper end surface of the upper frame is a horizontal plane. The upper end surface of the upper frame is used to place the seedling tray. The lower end surface of the lower frame is set parallel to the conveyor belt located directly below it. A channel for the seedling tray to pass through is formed between the conveyor belt and the lower end surface of the lower frame.

[0010] Based on the above scheme, as a preferred option, the lower end face of the lower frame is connected to the seedling tray pressure plate by a spring, and the front and rear ends of the seedling tray pressure plate are raised upwards.

[0011] Based on the above scheme, as a preferred option, the frame is equipped with a combined box, which includes a soil-laying box, a seeding box, and a soil-covering box arranged sequentially in the front-to-back direction.

[0012] Based on the above scheme, as a preferred option, the soil spreading box is equipped with a soil stirring rod and a soil spreading conveyor belt 1 below it; the seeding box is equipped with a seeding rod and a seed shortage alarm sensor; and the soil covering box is equipped with a soil stirring rod and a soil spreading conveyor belt 2 below it.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The difference in diameter between the large and small wheel systems creates an angle within the machine, resulting in a smooth and even lower chassis and more reliable movement. The support rollers are located inside the machine, solving the problem of wasted land due to their external placement.

[0015] Furthermore, during use, the small gear drives the large and small gears, which in turn drive the support rollers, making it easier to lift the frame.

[0016] The tray-laying frame design makes full use of the machine's unused space. During use, the seedling trays can be placed on the frame, freeing up the operator's hands and making tray placement more convenient, greatly improving work efficiency. A tray-pressing plate is also included to ensure accurate and smooth tray placement. Attached Figure Description

[0020] The present invention will be further described below through embodiments, but the scope of the present invention is not limited thereto.

[0021] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof. Example

[0022] like Figure 1-3 As shown, a self-propelled seedling tray seeding machine includes a frame 1 and a small wheel set 2 and a large wheel set 3 mounted on the frame. The small wheel set and the large wheel set are spaced apart in the front-to-back direction. The frame has side frames 4 on both sides. The small wheel set and the large wheel set are rotatably mounted on the side frames. A small gear 5 is rotatably mounted on the outer end face of the side frame. The small gear meshes with the large gear. The large gear is fixed on the gear shaft 7. The gear shaft is rotatably connected to the side frame. The gear shaft is fixedly connected to the wheel axle 9 through a connector 8. A support roller 10 is rotatably mounted on the wheel axle. The support roller is located in the middle between the two side frames.

[0023] In the above scheme, the difference in diameter between the large and small gears creates an angle in the machine, resulting in a smooth and even lower chassis and more reliable movement. The support rollers are located inside the side frame, which solves the problem of wasting land due to their external placement. Furthermore, during use, the small gear drives the large and small gears, which in turn drive the support rollers, making it easier to lift the frame.

[0024] There are two support rollers, which are rotatably mounted on both ends of the axle. The middle part of the axle is fixedly connected to the middle part of the gear shaft through a connector. The two ends of the gear shaft are rotatably connected to two side frames respectively.

[0025] The pinion is fixed on the pinion shaft, which is rotatably mounted on the side bracket. The end of the pinion shaft has a polygonal groove or a polygonal extension.

[0026] It also includes a crank that can be inserted into a polygonal groove or fitted onto a polygonal extension at one end.

[0027] The long crank handle fits into the end of the pinion shaft, making it easier to turn the pinion.

[0028] The upper end of the crank handle is fitted with a rubber sleeve to form a handhold. The handhold has an uneven surface to facilitate manual turning of the crank handle. The large and small gears and the crank handle form a manual, effortless turning and quick-moving mechanism. Example

[0029] Based on Example 1, to further optimize the ease of use of the seeder and make full use of the machine space, the following design is made: a tray rack is fixedly installed on the side of the frame near the handle 19. The tray rack includes an upper frame 11, a lower frame 12, and a side frame formed by several square tubes fixedly connected together. The side frame is fixed on the side frame, and the upper frame and lower frame are fixedly connected to the side frame. When the large wheel set and the small wheel set are in contact with the ground, the upper end surface of the upper frame is a horizontal plane. The upper end surface of the upper frame is used to place the seedling tray. The lower end surface of the lower frame is parallel to the conveyor belt located directly below it. A channel for the seedling tray to pass through is formed between the conveyor belt and the lower end surface of the lower frame.

[0030] This design makes full use of the machine's idle space. When in use, the seedling trays can be placed on the tray rack, freeing up the operator's hands, making tray placement more convenient, and greatly improving work efficiency. Example

[0031] Based on Example 2, since the tray placement is done manually, there is a problem that the seedling trays may tilt during the placement process. The following design is made: the lower end of the lower frame is connected to the seedling tray pressure plate 14 through the spring 13, and the front and rear ends of the seedling tray pressure plate tilt upward.

[0032] In this design, the raised seedling tray can be adjusted to ensure accurate and smooth lowering of the tray.

[0033] Example 4 (This part is a conventional design)

[0034] Based on any of the embodiments in Examples 1-3, a combined box is provided on the frame, which includes a soil-laying box 15, a seeding box 16, and a soil-covering box 17 arranged sequentially in the front-to-back direction.

[0035] The soil spreading box is equipped with a soil mixing rod and a soil spreading conveyor belt below it. The seeding box is equipped with a seeding rod and a seed shortage alarm sensor. The soil covering box is equipped with a soil mixing rod and a soil spreading conveyor belt below it. A stainless steel sliding plate 18 is installed at the rear end of the soil spreading conveyor belt 2.
