Detailed Embodiment

[0024] The principles and features of the present utility model will be described below in conjunction with embodiments; the examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0025] An alfalfa deep sowing machine includes a suspension 1, a hopper 2, a plow blade 4, and a soil covering wheel 7.

[0026] One end of the suspension 1 is connected to a tractor, which is generally a common agricultural tractor. The suspension 1 is a common structure in existing agricultural implements. Specifically, it is formed by welding square tubes and includes a first cross bar 8 and a second cross bar 9 that are arranged parallel to each other and welded together. The second cross bar 9 is connected with a second auxiliary rod 11 that extends obliquely downward. The soil covering wheel 7 is rotatably connected to a U-shaped frame 13. One end of the U-shaped frame 13 is hinged to the end of a support rod 5. A spring strut 14 is connected between the second auxiliary rod 11 and the U-shaped frame 13. The spring strut 14 has a tendency to elongate without external force, so that the soil covering wheel 7 presses tightly against the road surface, thereby covering the groove opened by the plow blade 4 with soil. The soil covering wheel 7 has a conical groove that can cover the groove opened by the plow blade with soil.

[0027] The hopper 2 is connected to the suspension 1 by welding. Specifically, the hopper 2 is connected to the second cross bar 9. A material pipe 3 extends downwardly from the lower part of the hopper 2. In this embodiment, two hoppers 2 are provided and are arranged in parallel. A sowing wheel 15 and a baffle 16 are rotatably connected in the hopper 2. The baffle 16 is connected to one side wall of the hopper 2, and its function is to limit the seeds to fall only from one side. The sowing wheel 15 is provided with seed grooves 17 arranged in a circumferential array. The seeds fall from the hopper 2 into the seed grooves 17. The sowing wheel 15 rotates, and the seeds in the seed grooves 17 fall into the material pipe 3 and finally into the land. The plow blade 4 corresponds to the hopper 2 one by one. The plow blade 4 is arranged below the suspension 1, and the bottom of the material pipe 3 is tied to the plow blade 4. The top of the plow blade 4 is connected with a support rod 5. The top end of the support rod 5 is hinged to the suspension 1. An expansion link 6 is connected between the support rod 5 and the suspension 1. The expansion link 6 is an oil cylinder. Adjusting the telescopic length of the oil cylinder can adjust the plowing depth of the plow blade 4, and thus control the sowing depth of alfalfa seeds. In order to adapt to the plow blade 4 with adjustable depth, a corrugated pipe 25 is provided at the top of the material pipe 3, so that the overall length of the material pipe 3 can also be adjusted.

[0028] In order to prevent the seeds in the silo 2 from caking during the sowing process and affecting the feeding, the silo 2 is rotatably connected with a stirring rod 18, and the stirring rod 18 is arranged above the sowing wheel 15. Specifically, wheels 12 are arranged on both sides of the suspension 1. A first sprocket wheel 20 is connected to a first wheel shaft 19 for supporting the rotation of the wheels 12, and a second sprocket wheel 22 is connected to a second wheel shaft 21 for supporting the rotation of the sowing wheel 15. The first sprocket wheel 20 and the second sprocket wheel 22 are driven by a chain; the second wheel shaft 21 is further connected with a first pulley 23, one end of the stirring rod 18 is connected with a second pulley 24, and the first pulley 23 and the second pulley 24 are driven by a belt. The first sprocket wheel 20 and the second sprocket wheel 22, and the first pulley 23 and the second pulley 24 are respectively arranged close to both sides of the suspension 1. Such a driving method can ensure the synchronous rotation of the wheels 12, the stirring rod 18 and the sowing wheel 15.

[0029] The device controls the grooving depth of the plow blade 4 through the telescopic rod 6, so as to ensure the planting depth of alfalfa seeds and the tillage effect.

[0030] The above are only the preferred embodiments of the present utility model; they are not intended to limit the present invention; any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
