Description

Technical Field

[0001] The utility model relates to the technical field of seed drills, in particular to a suspended deep fertilization seed drill. Background Art

[0002] Sowing is one of the six major links in the agricultural production process. Mechanized sowing is the most complex and arduous task in the process of agricultural mechanization. With the widespread application of agricultural machinery in rural areas, fertilizer seeders account for the majority of usage. Deep fertilizer seeders mainly include frames, furrow openers, seed feeders and fertilizer applicators. During operation, the fertilizer legs on the frame will be inserted into the soil and moved to achieve deep fertilization. The fertilizer legs are generally connected by welding or U-bolts. The welding connection has the disadvantage that the fertilization depth cannot be adjusted. Although the U-bolt connection can be adjusted, the U-bolts need to be disassembled one by one during the adjustment process, which makes the adjustment process cumbersome and inconvenient to use.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-3 , this embodiment provides a technical solution: a suspended deep fertilization seeder, comprising a frame 1 and a fixing unit 6;

[0021] Frame 1: There are three suspension seats 2 distributed in a triangular shape on its left side. The middle part of the frame 1 is slidably connected with evenly distributed fertilizer legs 3. The suspension seat 2 is connected to the suspension unit at the rear of the tractor, and then the fertilizer is added to the fertilizer bucket at the upper end of the middle part of the frame 1, and the seeds are added to the seed bucket on the right side of the frame 1. The tractor drives the fertilizer legs 3 and the sowing legs on the right through the frame 1 to insert into the ground and move to the left. The wheel on the right end contacts the soil, and during the movement, it drives the seed meter in the seed bucket to rotate, which can be planted as needed, thereby achieving fertilization and sowing. Nut blocks 4 are provided at the right ends of multiple fertilizer legs 3, and the number of fertilizer legs 3 can be freely set, and three can be set. The middle part of the frame 1 is rotatably connected with evenly distributed screw rods 5, and multiple screw rods 5 are threadedly connected to the vertically corresponding nut blocks 4. The screw rods 5 drive the fertilizer legs 3 to move up and down along the frame 1 through the nut blocks 4. The internal sliding connection is equipped with evenly distributed pressure blocks 13, and multiple pressure blocks 13 are arranged in cooperation with the longitudinal corresponding fertilizing legs 3. The pressure blocks 13 press the fertilizing legs 3, thereby achieving the locking of the fertilizing legs 3. The number of screw rods 5 and pressure blocks 13 is consistent with the number of fertilizing legs 3. It also includes vertical plates 11, which are respectively arranged at the left ends of the fertilizing legs 3. The vertical plates 11 improve the structural strength of the fertilizing legs 3. The left ends of the vertical plates 11 are V-shaped, which is convenient for soil diversion and avoids soil accumulation. The middle part of the frame 1 is rotatably connected to the transmission shaft 8. The outer arc surface of the transmission shaft 8 is provided with evenly distributed bevel gears 2 9. The upper ends of multiple screw rods 5 are provided with bevel gears 1 7. The bevel gears 2 9 are all meshed with the vertical corresponding bevel gears 1 7. The front end of the transmission shaft 8 is provided with a handwheel 10. When the handwheel 10 is rotated, the handwheel 10 drives the bevel gear 2 9 to rotate through the transmission shaft 8, and the bevel gear 2 9 drives the screw rod 5 to rotate through the bevel gear 1 7.

[0022] The fixing unit 6 is used for adaptive pressing of multiple pressure blocks 13. The fixing unit 6 includes an internal threaded tube 61, a pull rod 62, a large pressure rod 63 and a small pressure rod 64. The internal threaded tube 61 is rotatably connected to the middle part of the frame 1. The internal thread of the internal threaded tube 61 is connected to the pull rod 62. The right end of the pull rod 62 is rotatably connected to the large pressure rod 63. The front and rear ends of the large pressure rod 63 are rotatably connected to the small pressure rod 64. The pressure blocks 13 are all arranged in cooperation with the laterally corresponding small pressure rods 64. The right end of the internal threaded tube 61 is provided with a handle rod 12. The internal threaded tube 61 is rotated by the handle rod 12, and the pull rod 62 drives the large pressure rod 63 and the small pressure rod 64 to move to the left. The small pressure rod 64 squeezes the pressure block 13 to the left. During the tightening of the pull rod 62, the small pressure rod 64 and the large pressure rod 63 can be adaptively tilted to ensure that all the pressure blocks 13 are pressed synchronously.

[0023] The working principle of a suspended deep fertilizer seeder provided by the utility model is as follows: when in use, the suspension seat 2 is connected to the suspension unit at the rear of the tractor, and then fertilizer is added to the fertilizer bucket at the middle upper end of the frame 1, and seeds are added to the seed bucket on the right side of the frame 1. The tractor drives the fertilizing leg 3 and the sowing leg on the right through the frame 1 to insert into the ground and move to the left. The wheel at the right end contacts the soil, and during the movement, it drives the seed meter in the seed bucket to rotate, so that seeds can be planted as needed, thereby achieving fertilization and sowing. During the sowing process, the depth of fertilization can be adjusted according to planting needs. During adjustment, the internal threaded tube 61 is driven to rotate by the handle rod 12, and the internal threaded tube 61 drives the non-rotating pull rod 62 to move to the right, and the pull rod 62 drives the large pressure rod 63 and the small pressure rod 64 to move right to loosen the pressure block 13. Then rotate the handwheel 10, the handwheel 10 drives the bevel gear 2 9 to rotate through the transmission shaft 8, and the bevel gear 2 9 drives the screw rod 5 to rotate through the bevel gear 1 7, and the screw rod 5 drives the fertilizing leg 3 to move up and down along the frame 1 through the nut block 4, so that the depth of the fertilizing leg 3 inserted into the soil can be adjusted. After the adjustment is completed, the internal threaded tube 61 is rotated by the handle rod 12, and the pull rod 62 drives the large pressure rod 63 and the small pressure rod 64 to move to the left, and the small pressure rod 64 squeezes the pressure block 13 to the left, and the pressure block 13 presses the fertilizing leg 3, so as to achieve the locking of the fertilizing leg 3, and the large pressure rod 63 is rotatably connected to the pull rod 62, and at the same time, the middle part of the small pressure rod 64 is rotatably connected to the large pressure rod 63, and then in the process of tightening the pull rod 62, the small pressure rod 64 and the large pressure rod 63 can be adaptively tilted to ensure that all the pressure blocks 13 are synchronously pressed.
