The compression bar 22 is a hollow bar structure, the compression bar 22 is vertically inserted into the seeding cylinder 21, the compression bar 22 is provided with a feed inlet 221, the feed inlet 221 is positioned above the quantitative cache box 32, the compression bar 22 is pressed downwards to enable the feed inlet 221 to be communicated with the inner cavity of the quantitative cache box 32, the reset spring 24 is sleeved on the compression bar 22, the top end of the reset spring 24 is abutted on the compression bar 22, and the bottom end of the reset spring is abutted in the seeding cylinder 21. The seeding awl 23 is installed at the bottom of the pressure lever 22, the awl point of the seeding awl 23 extends out of the seeding cylinder 21, and the pull rope 25 is connected with the seeding awl 23.

As shown in fig. 2 and 3, the seed collecting box 31 and the quantitative buffer box 32 in the present invention are both rectangular box structures, a first feeding hole 313 is provided on the left end surface of the seed collecting box 31, a first discharging hole 314 is provided on the right end surface, and the first feeding hole 313 is used for injecting seeds into the seed collecting box 31. A second feeding hole 323 is arranged on the left end face of the quantitative buffer box 32, and a second discharging hole 324 is arranged on the right end face. Seed collecting box 31 and quantitative cache case 32 pass through screw fixed connection, and first discharge opening 314 is linked together with second feed opening 323, is equipped with U-shaped slot 326 on the left side terminal surface of quantitative cache case 32, and open-close plate 33 is vertical pegs graft in U-shaped slot 326, is equipped with the buffering hole 331 of rectangle form on open-close plate 33, and first discharge opening 314 link up mutually with second feed opening 323 through buffering hole 331.

Referring to fig. 4, 5 and 6, in the initial state, i.e. when the pressing rod 22 is not pressed down, the first discharging hole 314 is communicated with the second feeding hole 323 through the buffering hole 331 (as shown in fig. 4), at this time, the seeds in the seed collecting box 31 enter the quantitative buffering box 32, and a part of the seeds are accumulated between the seed collecting box 31 and the quantitative buffering box 32, i.e. in the buffering hole 331 of the opening and closing plate 33.

When the seeds in the quantitative buffer box 32 need to be fed into the pressure rod 22, the pressure rod 22 is pressed downwards at the moment, the pressure rod 22 drives the opening plate 33 to move downwards together, and when the feed inlet 221 on the pressure rod 22 is communicated with the second discharge hole 324 on the quantitative buffer box 32, the seeds in the quantitative buffer box 32 enter the pressure rod 22. At the same time, the buffer hole 331 of the opening plate 33 moves to the lower side of the first discharging hole 314 and the second feeding hole 323 (as shown in fig. 5), and the inner cavity of the seed collecting box 31 is separated from the inner cavity of the quantitative buffer box 32. The seeds in the seed-collecting box 31 cannot be fed into the quantitative buffer box 32.

When the pressing rod 22 moves upward and returns to the initial position, the first discharging hole 314, the buffer hole 331 and the second feeding hole 323 are communicated again (as shown in fig. 6), so that the seeds continuously enter the quantitative buffer tank 32 and fill the quantitative buffer tank 32, and when the pressing rod 22 is pressed again, the seeds continuously enter the pressing rod 22 according to the above process.

The rectangular buffer hole 331 is formed in the opening plate 33 in the present invention, and in the process that the opening plate 33 moves downward and closes the first discharging hole 314 and the second feeding hole 323, since some seeds are accumulated between the seed collecting box 31 and the quantitative buffer box 32, when the opening plate 33 moves downward, the seeds accumulated between the seed collecting box 31 and the quantitative buffer box 32 are accommodated in the buffer hole 331 (as shown in fig. 5), and the some seeds are not clamped between the seed collecting box 31 and the quantitative buffer box 32, so as to restrict the downward movement of the opening plate 33, and when the opening plate 33 moves downward, due to the existence of the buffer hole 331, the seeds positioned between the seed collecting box 31 and the quantitative buffer box 32 are not crushed.

Rectangular extension plates 38 are arranged on the bottom surfaces of the seed collecting box 31 and the quantitative buffer box 32, a gap formed between the two rectangular extension plates 38 is communicated with the U-shaped slot 326, and the opening-closing plate 33 moves downwards in the gap between the two rectangular extension plates 38. The two rectangular extension plates 38 function to prevent the seeds from being separated from the buffer holes 331 by the shielding of the two rectangular extension plates 38 when the buffer holes 331 on the opening plate 33 are moved to the lower side of the first discharging hole 314 and the second feeding hole 323.

As shown in fig. 7 and 8, a positioning groove 220 is vertically arranged on the outer wall of the pressing rod 22, the feeding port 221 is arranged in the positioning groove 220, the right end face of the quantitative buffer tank 32 extends into the positioning groove 220, the pressing rod 22 is pressed downwards, and when the feeding port 221 is communicated with the second discharging hole 324, the inner cavity of the pressing rod 22 is communicated with the inner cavity of the quantitative buffer tank 32.

The positioning groove 220 is matched with the quantitative buffer box 32, so that the motion stability of the pressure rod 22 is ensured, and the gap between the pressure rod 22 and the quantitative buffer box 32 is reduced, so that seeds can enter the pressure rod 22 more efficiently.

When seeds enter the quantitative buffer tank 32 from the seed collecting tank 31, in order to prevent the seeds from being blocked at the position of the first discharge hole 314 on the seed collecting tank 31, the invention arranges a movable discharging guide plate 311 in the seed collecting tank 31, and the discharging guide plate 311 is shaken or vibrated by striking the discharging guide plate 311, thereby preventing the seeds from being blocked at the position of the first discharge hole 314.
