[0002] In addition to carbohydrates, proteins, fats, and carotene, corn also contains isomaltooligosaccharides, riboflavin, vitamins, and other nutrients. As one of the main crops in agricultural planting, corn is widely planted and cultivated. With the development of agricultural planting, corn has gradually been transformed from traditional manual sowing to mechanical sowing, as shown in a corn seeder (Announcement No. CN218679974U) disclosed in the China Patent Network. When such a device is in use, the corn seeds can be transported to the sowing wheel through the corn seed storage basin and seed delivery tube provided in the corn seeder, and the provided sowing wheel and sowing tube can gradually sow the corn seeds into the soil by rolling, so that when sowing the corn seeds, the sowing of the corn can be completed by pushing the device to move by the push rod and the push handle.

[0003] However, there are still some shortcomings in the above-mentioned patents and corn seeders adopted in the existing market: the existing method of using a sowing wheel to rotate, using its sowing tube to dig a hole and sowing corn seeds synchronously, while the sowing tube digs a hole in the soil, the soil is very easy to block its pipe opening, resulting in the inability to drop corn for sowing, and the sowing stability is poor. To this end, those skilled in the art provide a convenient corn seeder to solve the problems raised in the above background technology. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Please refer to Figure 1-4 As shown, a portable corn seeder includes a cart frame 1, a push handle 2 is provided at one end of the carrier of the cart frame 1, and the push handle of the push handle 2 is covered with an anti-slip rubber sleeve. Through the setting of the push handle 2, when the brake motor 6 drives the mechanical rotation of the brake wheel 3, the staff only needs to push the push handle 2 to control the moving direction of the seeder, so as to control the corn sowing work.

[0025] Two groups of brake shafts 7 are installed under the carrier of the cart frame 1, and brake wheels 3 are installed at both ends of the shaft rod of each group of brake shafts 7. Brake motors 6 are symmetrically installed above the carrier of the cart frame 1 in a direction perpendicular to the brake shafts 7, and the brake motors 6 and the brake shafts 7 are connected by a first transmission belt 8, the brake shafts 7 and the pit-opening mechanism 5 are connected by a second transmission belt 9, and the pit-opening mechanism 5 and the sowing mechanism 4 are connected by a third transmission belt 10. A first differential pulley adapted to the first transmission belt 8 is provided between the brake motor 6 and the brake shaft 7, and a second differential pulley adapted to the second transmission belt 9 is provided between the brake shaft 7 and the pit-opening mechanism 5. A third differential pulley matched with the third transmission belt 10 is arranged between the hole-opening mechanism 5 and the sowing mechanism 4. Based on the brake motor 6 as the driving source, under the transmission of the first transmission belt 8, the brake shaft 7 is driven to rotate, and then the brake wheels 3 at both ends of the shaft are driven to rotate, so as to push the seeder forward. While the brake shaft 7 rotates, under the transmission of the second transmission belt 9, the hole-opening mechanism 5 is driven to operate, so as to circulate holes in the soil as a planting trough for corn. Further, while the hole-opening mechanism 5 is operating, under the transmission of the third transmission belt 10, the sowing mechanism 4 is driven to operate, so that the corn circulating sowing material is discharged and falls into the planting trough with the circulating groove.

[0026] A sowing mechanism 4 is installed on one side above the carrier of the cart frame 1, and the sowing mechanism 4 includes two sets of sowing bases 41 facing each other horizontally, a first linkage shaft 43 is installed between the two sets of sowing bases 41, and both ends of the shaft rod of the first linkage shaft 43 are provided with a sowing disk 44 adapted to the sowing base 41, a hopper 46 is provided at the upper end of the support of the sowing base 41, and a sowing pipe 42 vertically opposite to the sowing disk 44 is provided at the lower end of the support of the sowing base 41, and the sowing disk 44 is provided with a plurality of sets of material placing troughs 45 arranged along its circumference, and the material placing troughs 45 are vertically opposite to the discharge pipe opening of the material placing pipe 42. During the operation of the sowing mechanism 4, the third transmission belt 10 drives the first linkage shaft 43 to rotate, and then drives the sowing disk 44 to rotate, so that the corn fallen into the material placing trough 45 is turned over for sowing, and is circulated through the sowing pipe 42, and then falls into the corresponding planting trough under the forward braking of the seeder.

[0027] A hole-digging mechanism 5 horizontally opposite to the sowing mechanism 4 is installed on the other side above the carrier of the cart frame 1. The hole-digging mechanism 5 includes a support frame 51 and two sets of guide sleeves 52 horizontally opposite to each other. A hole-digging rod 53 is slidably connected inside the shaft sleeve of the guide sleeve 52. A second linkage shaft 56 is rotatably connected to the top of the support frame 51, and eccentric wheels 55 are installed at both ends of the shaft rod of the second linkage shaft 56. The eccentric wheel 55 is connected to the hole-digging rod 53 through an arm push rod 54. During the operation of the hole-digging mechanism 5, the second transmission belt 9 drives the second linkage shaft 56 to rotate, and then drives the eccentric wheel 55 to rotate. The reciprocating transmission combination of the eccentric wheel 55 and the arm push rod 54 is utilized to push the hole-digging rod 53 to slide up and down cyclically along the guide sleeve 52, so as to perform cyclic hole-digging work on the soil on the travel path as a planting trough for corn.

[0028] The working principle of the utility model is as follows: when sowing corn, the corn is poured into the hopper 46 of the sowing mechanism 4 in advance, and then the seeder frame is placed next to the soil to be planted. At this time, the brake motor 6 is controlled to work as a driving source. Under the drive of the first transmission belt 8, the brake shaft 7 is driven to rotate, and then the brake wheels 3 at both ends of the shaft are driven to rotate, so as to push the seeder forward. The staff only needs to hold the push handle 2 to control the seeder to move forward.

[0029] While the brake shaft 7 rotates, the second transmission belt 9 drives the second linkage shaft 56 in the pit-opening mechanism 5 to rotate, and then drives the eccentric wheel 55 to rotate. The reciprocating transmission combination of the eccentric wheel 55 and the arm force push rod 54 is used to push the pit-opening rod 53 to slide up and down along the guide sleeve 52 in a circular manner, so as to perform a circular pit-opening work on the soil on the travel path, which serves as a planting trough for corn.

[0030] While the pit opening mechanism 5 is further operating, under the transmission of the third transmission belt 10, the first linkage shaft 43 in the sowing mechanism 4 is driven to rotate, and then the sowing plate 44 is driven to rotate, the corn fallen into the material trough 45 is turned over and sown, and is circulated through the sowing pipe 42, and then falls into the corresponding planting trough under the forward braking of the seeder, so that the corn is sown conveniently, efficiently and accurately.

[0031] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
