[0001] The present invention relates to the field of agricultural machinery, in particular to a pit digging and fertilizing seeder. Background Art

[0002] With the exception of rice, planting virtually all crops requires three steps: digging, fertilizing, and sowing. A V-shaped pit must be dug with a hoe on the leveled ground, then fertilizer is applied and seeds are sown. In the absence of a pit digger, some areas use a plow hook instead. This has two drawbacks: first, it can't achieve the required pit depth and width; second, it requires re-measuring the distance between fertilizing and sowing.

[0003] Fertilizer spreaders have complex disadvantages, and the fertilizers applied are on the ground, and most fertilizers are easily soluble in water, causing fertilizer loss. In addition, simple fertilizer seeders spread fertilizers or crop seeds on the ground through plastic tubes installed at the bottom of the container box. Since fertilizers or plant seeds easily stick to each other, the contact between seeds and fertilizers can easily cause damage to the seeds. Summary of the Invention

A main transmission shaft 201 and a secondary transmission shaft 202 are arranged inside the body 2, a worm 203 is arranged at the top end of the main transmission shaft 201, a worm gear 204 and a special curve wheel 205 are arranged at the top end of the secondary transmission shaft 202, a round wheel 3 is arranged on the top side of the body 2, and there are two round wheels 3. A fertilizer container 301 and a seed container 303 are respectively arranged inside the round wheel 3, and a fertilizer hopper 302 and a seed hopper 304 are respectively arranged at the top end of the round wheel 3. A return spring block 4 is provided at the bottom end of the body 2, and a return spring 4011 pad is provided inside.

[0021] Furthermore, an engine is provided inside the front of the vehicle 1, and the engine is connected to the wheel 101 and the main transmission shaft 201 respectively. The secondary transmission shaft 202 is connected to the main transmission shaft 201 through the worm 203 and the worm wheel 204. When the engine provided inside the front of the vehicle 1 is started, on the one hand, it drives the wheel 101 to rotate and drive the vehicle body 2 to move forward, and on the other hand, it drives the main transmission shaft 201 to rotate. When the main transmission shaft 201 rotates, it drives the secondary transmission shaft 202 respectively through the worm gear and the worm wheel 204.

[0022] Furthermore, the secondary transmission shaft 202 is connected to the special curve wheel 205, and a hoe rod 401 is provided at the bottom end of the special curve wheel 205, and a hoe plate 4012 is provided at the bottom end of the hoe rod 401. A return spring 4011 is provided on the surface of the hoe rod 401, and a return spring block 4 is provided on the top side of the hoe plate 4012. The top of the hoe rod 401 is connected to the special curve wheel 205, and a worm gear 204 and a special curve wheel 205 are placed on the secondary transmission shaft 202. The secondary transmission shaft 202 is connected to the main transmission shaft 201 through the worm 203 and the worm gear 204. The outer diameter of the special curve wheel 205 increases from the minimum outer diameter to the maximum outer diameter with equal length. After increasing to the maximum outer diameter, it decreases with equal length until it reaches the minimum outer diameter. The return spring 4011 block is fixed on the vehicle body 2, with a hoe rod 401 on it, a hoe plate 4012 at the lower end of the hoe rod 401, and a return spring 4011 on the hoe rod 401. The return spring 4011 keeps the hoe bar 401 against the special curve wheel 205 at all times.

[0023] Furthermore, the special curve wheel 205 is an elliptical structure, the special curve wheel 205 is a detachable structure, the return spring block 4 is fixedly set at one end of the vehicle body 2, and when V-shaped pits of different sizes need to be dug, different special curve wheels 205 are replaced.

[0024] Furthermore, the round wheel 3 is connected to the secondary transmission shaft 202, and a short scraper plate 5 and a long scraper plate 6 are installed at the bottom end of the vehicle body 2. The length of the long scraper plate 6 is greater than that of the short scraper plate 5. The long scraper plate 6 is arranged obliquely below the seed container 303, and the short scraper plate 5 is arranged obliquely below the fertilizer container 301. After fertilization is completed, the short scraper plate 5 under the vehicle body 2 scrapes off a small part of the V-shaped longitudinal soil and covers it on the fertilizer so as not to damage the seeds to be sown later. After sowing is completed, the soil is covered with the long scraper plate 6 to cover the V-shaped pit.

[0025] Furthermore, the fertilizer hopper 302 is connected to the fertilizer container 301, and the seed hopper 304 is connected to the seed container 303. When the main transmission shaft 201 drives the secondary transmission shaft 202 to rotate through the worm 203 and the worm wheel 204, the circular wheel 3 on the secondary transmission shaft 202 is driven to rotate. There is a hole on the circular wheel 3, and the fertilizer container 301 is arranged in the hole. When the circular wheel 3 rotates, the fertilizer container 301 brings out the fertilizer in the fertilizer hopper 302 and spreads it in the V-shaped pit to complete fertilization. The transmission shaft drives the secondary transmission shaft 202 to rotate through the worm 203 and the worm wheel 204. The secondary transmission shaft 202 has a circular wheel 3. There is a hole on the rotating circular wheel 3, and the seed container 303 is arranged in the hole. When the circular wheel 3 rotates, the seeds are transferred out of the seed hopper 304 when the seed container 303 rotates and are spread in the V-shaped pit to complete the sowing work.

[0026] Furthermore, a rubber plate 3041 is installed inside the seed bucket 304, and the rubber plate 3041 prevents the seeds from being damaged when the circular wheel 3 rotates.

[0027] The present invention is used in the following manner:

[0028] When the engine of the front of the vehicle 1 drives the vehicle body 2 to move forward on the one hand, and drives the main transmission shaft 201 to rotate on the other hand, when the main transmission shaft 201 rotates, it drives the secondary transmission shaft 202 respectively through the worm and worm wheel 204. When the secondary transmission shaft 202 rotates, it drives the special curve wheel 205 mounted on it to rotate. The outer diameter of the special curve wheel 205 increases from the minimum diameter to the maximum diameter, and then decreases again to the minimum outer diameter after reaching the maximum outer diameter, and does two rounds in one circle. When the special curve wheel 205 rotates, the hoe rod 401 on the upper machine surface moves up and down at a uniform speed relative to the vehicle body 2. At this time, the vehicle body 2 moves forward at a uniform speed in a straight line driven by the engine of the front of the vehicle 1. The two movements are superimposed, and the hoe rod 401 makes a V-shaped motion relative to the ground. Every time it makes a V-shaped motion, the hoe plate 4012 digs a V-shaped pit on the ground.

[0029] When the main transmission shaft 201 drives the auxiliary transmission shaft 202 to rotate through the worm 203 and the worm wheel 204, the circular wheel 3 on the auxiliary transmission shaft 202 is driven to rotate. There is a hole on the circular wheel 3, and a fertilizer container 301 is arranged in the hole. When the circular wheel 3 rotates, the fertilizer container 301 brings out the fertilizer in the fertilizer hopper 302 and spreads it in the V-shaped pit to complete the fertilization. At the same time, the short scraper 5 under the vehicle body 2 scrapes off a small part of the soil in the longitudinal direction of the V-shape and covers it on the fertilizer to prevent the seeds to be sown later from being damaged. The fertilizer is covered with soil and the relationship between the fertilizer and the seeds is maintained. The main transmission shaft 201 drives the auxiliary transmission shaft 202 to rotate through the worm 203 and the worm wheel 204. There is a round wheel 3 on the auxiliary transmission shaft 202. There is a hole on the rotating round wheel 3. There is a seed container 303 in the hole. When the round wheel 3 rotates, the seed container 303 rotates, and the seeds are transferred out from the seed bucket 304 and scattered in the V-shaped pit to complete the sowing work. Different seeds only need to replace different seed containers 303. After all the digging, fertilizing and sowing work is completed, the long scraper plate 6 covers the V-shaped pit with soil to bury the seeds.

[0030] The present invention is a pit digging, fertilizing and seeding machine. The device uses a special curved wheel 205 to drive a hoe rod 401 to move up and down, and uses the up and down movement of the hoe rod 401 to drive a hoe plate 4012, and a V-shaped pit is dug by the hoe plate 4012. Then, fertilizer is sprinkled inside the V-shaped pit through a fertilizer container 301, and then a certain amount of soil is scraped out by a short scraper plate 5 to bury the fertilizer. At the same time, the soil is used to isolate the fertilizer and subsequently sprinkled seeds. Finally, the soil is scraped by a long scraper plate 6 to fill the V-shaped pit, completing the operations of digging, fertilizing and seeding, thereby greatly improving labor production efficiency. In addition, the fertilization of the present invention is hole fertilization, which reduces fertilizer loss.

[0031] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
