Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0014] Example: This invention provides a seeding device, see [link to example]. Figures 1-3 The hopper includes a hopper 10, with a first discharge pipe 20 and a second discharge pipe 30 installed at the bottom of the hopper. A first trencher 21 is installed at the bottom of the first discharge pipe, and a second trencher 31 is installed at the bottom of the second discharge pipe. A pull rod 40 is fixed to the hopper. The first discharge pipe includes a first connecting pipe 22 and a first telescopic pipe 23, which are slidably connected. The end of the first connecting pipe not connected to the first telescopic pipe is connected to the bottom of the hopper. The first trencher is located at the end of the first telescopic pipe not connected to the first connecting pipe. A first lifting device 24 is fixed to the first telescopic pipe, and the power output end of the first lifting device is connected to the connecting pipe. The second feeding pipe includes a second connecting pipe 32 and a second telescopic pipe 33, which are slidably connected. The end of the second connecting pipe not connected to the second telescopic pipe is connected to the bottom end of the hopper. The second trencher is located at the end of the second telescopic pipe not connected to the second connecting pipe. A second lifting device 34 is fixed on the second telescopic pipe, and the power output end of the second lifting device is connected to the connecting pipe. The first and second lifting devices can be electric telescopic rods or hydraulic cylinders. The first connecting pipe and the first telescopic pipe are keyed, preferably using a spline connection. Similarly, the second connecting pipe and the second telescopic pipe are keyed, preferably using a spline connection.

[0015] When using the above-mentioned seeding device, place the device on the ground and pull the lever. Under the action of the device's gravity and pulling force, the furrow opener inserts into the soil to open a furrow. Seeds are supplied to the first and second feeding pipes through the hopper. The seeds fall into the furrow along the first and second feeding pipes. After the seeds fall into the furrow, they slide down the raised soil on both sides and are covered by the soil. In actual use, in order to ensure that the seeds entering the furrow are covered by the soil, ropes can be tied to the first and second connecting pipes respectively, and iron plates can be tied to the other end of the ropes. The iron plates push some of the soil from both sides of the furrow into the furrow behind the first and second connecting pipes.

[0016] When used on a flat surface, the bottom ends of the first and second telescopic rods can be adjusted to be level with each other using the first and second lifting devices. When used on sloping terrain such as mountainous areas, the bottom ends of the first and second telescopic rods can be adjusted to be higher or lower than the bottom ends of the second telescopic rods using the first and second lifting devices.

[0017] As a preferred implementation method, see [link to relevant documentation]. Figures 3-5The hopper includes a bottom plate 12 and a protective sleeve 11. The protective sleeve is generally made of metal, such as stainless steel. Preferably, the top opening area of ​​the protective sleeve is not larger than the bottom opening area, for example, in a funnel shape, to facilitate the sowing of seeds into the sleeve. The bottom end of the protective sleeve is connected to the bottom plate, and the connection position is not at the edge of the bottom plate. A strip-shaped interlayer 13 is provided inside the bottom plate. A first sealing plate 14 and a second sealing plate 15 are provided inside the strip-shaped interlayer. The top surface of the first sealing plate contacts the top surface of the interlayer, and the bottom surface contacts the bottom surface of the interlayer. The top surface of the second sealing plate contacts the top surface of the interlayer, and the bottom surface contacts the bottom surface of the interlayer. The bottom end of the bottom plate is provided with a connection to the bottom opening area. The interlayer is connected by a first oblong hole 16 and a second oblong hole 17, with a gap between them. The top end of the first connecting pipe passes through the first oblong hole and connects to the first sealing plate, and the top end of the second connecting pipe passes through the second oblong hole and connects to the second sealing plate. The first sealing plate is provided with a first connecting hole 161 that communicates with the first connecting pipe, and the second sealing plate is provided with a second connecting hole 171 that communicates with the second connecting pipe. The bottom end of the base plate is provided with a third oblong hole 19 and a fourth oblong hole 18 that communicate with the interlayer. The third oblong hole corresponds to the first oblong hole, and the fourth oblong hole corresponds to the second oblong hole. In use, forcefully moving the first and second connecting pipes allows the first and second sealing plates to move along the strip-shaped interlayer. The first connecting hole can move within the length of the third oblong hole, and the second connecting hole can move within the range of the fourth connecting hole. This allows for adjusting the distance between the first and second connecting pipes while ensuring that the seeds can fall smoothly into the first and second connecting pipes through the hopper, thus adjusting the spacing between the two rows of seeds after sowing. In actual manufacturing, a limiting device can also be installed on the top surface of the base plate to restrict and ensure stability after the first and second sealing plates have moved. As a preferred implementation method, see [link to relevant documentation]. Figure 6 and Figure 7A first strip block 50 is fixed to the first connecting pipe. The first strip block is horizontally positioned and has a first strip groove 51. A first slider 52 is disposed within the first strip groove, and a first support rod 53 is rotatably connected to the first slider. A first connecting block 54 is fixed to the second telescopic pipe. The end of the first support rod not connected to the first slider is rotatably connected to the first connecting block. A first limiting device for restricting the sliding of the first slider is provided on the first strip block or the first slider. A second strip block 60 is fixed to the second connecting pipe. The first strip block is horizontally positioned and has a second strip groove. A second slider is disposed within the second strip groove, and a second support rod 63 is rotatably connected to the second slider. A second connecting block 64 is fixed to the first telescopic pipe. The first support rod is not rotatably connected to the first slider. One end of the slider is rotatably connected to the first connecting block. The second strip block or the second slider is provided with a second limiting device for restricting the sliding of the second slider. In this application, the first limiting device and the second limiting device can use existing limiting devices. The following is one type of limiting device: the first strip groove is located on the bottom surface of the first strip block, and the top or side surface of the first strip block is provided with a first strip hole 55 communicating with the first strip groove. The first slider is threaded with a first fastening bolt 56, which passes through the first strip hole. The second strip groove is located on the bottom surface of the second strip block, and the top or side surface of the second strip block is provided with a second strip hole 65 communicating with the second strip groove. The second slider is threaded with a second fastening bolt 66, which passes through the first strip hole. When this structure is in use, after the first and second limiting devices fix the first and second sliders, the distance between the first and second feeding pipes is fixed, and the bottom ends of the first telescopic pipe and the second telescopic rod are also fixed. At this time, the positions of the first and second sealing plates are fixed because the distance between the first and second feeding pipes is fixed. When it is necessary to adjust the height of the bottom end of the first telescopic pipe, the second fastening bolt is loosened, and the height of the bottom end of the first telescopic pipe can be adjusted by the first lifting device. When the height is adjusted upward, the first connecting block pushes the second support rod, causing the second support rod to push against the second slider and move to the right. When the height is adjusted downward, the first connecting block pulls down the second support rod, causing the second support rod to pull back the second slider and move to the left. After adjusting the position, the second fastening bolt is tightened to increase the friction between the second slider and the second slide groove, thus limiting the second slider. Similarly, the height of the bottom end of the second telescopic pipe can be adjusted.The structure reinforces the first and second feed pipes by setting a first support rod and a second support rod, making the first and second feed pipes more stable during use. In addition, when the hydraulic cylinder is damaged, such as when the locking part of the hydraulic rod fails and cannot support the corresponding connecting pipe and telescopic pipe, the structure can maintain the supporting function and can keep the device usable in an emergency by manually lifting or pulling the corresponding telescopic pipe to adjust the height of the bottom end of the corresponding telescopic pipe.
