Description

Garlic seeder

Technical Field

The utility model relates to a garlic seeding machinery technical field.

Background

In the garlic seeder, not only rebroadcasting needs to be prevented, but also miss-seeding needs to be prevented, namely, each seeding position is ensured to sow one garlic seed, in the existing garlic seeder (see attached figures 8-9), the garlic seeder adopts an upper chain wheel and a lower chain wheel to form a front-back parallel annular support for a garlic conveying chain, seed scoops arranged on the chain at intervals are only provided with one seed scoop cavity, in order to prevent miss-seeding, the cavity of the seed scoop can contain more than two garlic seeds, the seed scoops of the rear chain are picked up by a garlic seed discharging box in the upward conveying process, and the redundant garlic seeds are removed by a weight removing mechanism which is composed of a motor 26, a knocking block, a reset spring 28 and a hexagonal shaft 29; the knocking block is of an L-shaped structure consisting of a vertical part 27 and a horizontal part 30, the front end face of the vertical part 27 is attached to the inner side of a chain, a return spring 28 is connected between the rear side of the top end of the vertical part 27 and the main body of the seed sowing device, one end, away from the vertical part 27, of the horizontal part 30 is rotatably connected with the main body of the seed sowing device through a rotating shaft, a hexagonal shaft 29 is rotatably arranged above the horizontal part 30, and the hexagonal shaft 29 is attached to the horizontal part 30; during operation, the motor 26 drives the hexagonal shaft 29 to rotate, the vertical portion 27 can be ejected out regularly at intervals in the rotating process of the hexagonal shaft 29, the vertical portion 27 can complete reciprocating motion, knocking on the chain is achieved, the seed spoon is vibrated, redundant garlic seeds in the seed spoon are shaken to fall into the garlic seed discharging box, and then the garlic seeds are turned downwards through the upper chain wheel for seeding. The above-mentioned duplicate removal mechanism has the following disadvantages: 1. when the seeder works in the field, because the road condition in the field is complex, the resistance is not constant or the variable is large in the seeding process, so that the current generated by the engine is unstable, the rotating speed of the motor 26 is forced to be uneven, the vibration frequency is influenced, and the weight removing effect is influenced; and the engine shake will also have an effect on it. 2. The hexagonal shaft 29 is in direct contact with the knocking block and the rotational speed of the hexagonal shaft 29 is high, so that the hexagonal shaft 29 is worn quickly, resulting in vibration failure. 3. Because the sizes of the garlic seeds are different, slightly smaller garlic seeds can fall off from the seed spoon under the vibration of higher frequency, and the weight removing effect of the vibration of lower frequency on slightly larger garlic seeds is not obvious. 4. As the seed sowing chain is tightly attached to the seed box, garlic seeds have high humidity and high friction force between garlic seeds in the actual sowing process, and the chain has a possibility of driving the garlic seeds to fall out of the seed box along the chain.

The garlic seeder of claim 3, wherein: the garlic seeding device is provided with a garlic conveying chain stretching mechanism, the seeding device support (2) is provided with a linear guide rail, the lower chain wheel (9) is rotatably connected with a sliding block, and a pressure spring is arranged between the sliding block and the seeding device support (2) to apply acting force to the lower chain wheel (9) along the direction of the linear guide rail so as to stretch the garlic conveying chain.

5. The garlic seeder of claim 4, wherein: a seed furrow holder and a furrow opener (11) are arranged at the bottom of the garlic seed metering device, the seed furrow holder is made of elastic silica gel and comprises a rotating wheel (12) and anti-slip strips (13), the wheel surface of the rotating wheel (12) is a cylindrical surface, and the anti-slip strips (13) are arranged on the wheel surface at intervals; the seed furrow holder is in rolling connection with the bottom of the seed sowing device support (2), is positioned at the rear end of the garlic seed sowing port (10), and the front end of the seed furrow holder is embedded into a gap between the left wing (11-1) of the furrow opener and the right wing (11-2) of the furrow opener, so that hilling on two sides of a furrow opened by the furrow opener (11) is blocked by the rotating wheel (12) when the rear ends of the left wing (11-1) of the furrow opener and the right wing (11-2) of the furrow opener are backfilled, and the width of the seed furrow is kept by the wheel surface of the seed furrow, so that garlic seeds fall into the bottom of the furrow, and therefore, the included angle between the left wing (11-1) of the furrow opener and the right wing (11-2) of the furrow opener and the underground depth are reduced at the same garlic planting depth, so as to reduce the ditching resistance and save energy; the anti-slip strips (13) are used for increasing the friction force between the rotating wheels (12) and the ground so as to keep the rotating wheels in a rotating state, and in the process of advancing, garlic seeds are lightly stroked and positioned in soil, so that the rotating wheels (12) are prevented from stopping rotating and rubbing forwards due to small friction force, and the garlic seeds are rubbed forwards away from the sowing position so as to influence the sowing distance.

6. The garlic seeder of claim 5, wherein: the transmission structure of the garlic seeder is a shaft hub connection structure: the garlic seeding device comprises a bearing inner hole of a front chain wheel (8) and shaft sleeves (14) which are fixedly connected in the garlic seeding devices, wherein the inner hole of each shaft sleeve (14) is a transmission hole, the section of each shaft sleeve is polygonal, a transmission shaft (15) of the garlic seeding device is connected with the transmission holes of the garlic seeding devices in a sliding fit manner, the section of the transmission shaft (15) of the garlic seeding device is polygonal and matched with the section of the inner hole of each shaft sleeve (14) so as to fix the garlic seeding devices and the shaft sleeves in a circumferential direction, and one end of the transmission shaft (15) of the garlic seeding device is provided with a transmission chain wheel or a gear which is used for being.

7. The garlic seeder of claim 6, wherein: a driving device, a wheel transmission chain and a garlic seeding device chain transmission structure are arranged on the rack (1); the driving device comprises a diesel engine or a gasoline engine (16), a main clutch (17) and a transmission (18), wherein the transmission (18) converts high-speed output of a power output shaft of the diesel engine or the gasoline engine (16) into low-speed high-torque power output through the power output shaft of the transmission (18), and the power transmission between the diesel engine or the gasoline engine (16) and the transmission (18) is switched on or off through the main clutch (17); the power output shaft of the speed changer (18) drives wheels to rotate through a wheel transmission chain; the chain transmission structure of the garlic seeding device comprises an auxiliary clutch (19) and a garlic seeding device transmission chain, wherein a power output shaft of a transmission (18) drives a transmission chain wheel at one end of a garlic seeding device transmission shaft (15) to rotate through the garlic seeding device transmission chain, so that the garlic transmission chain of the garlic seeding device is rotated and is switched on or switched off through the auxiliary clutch (19), and the power output shaft of the transmission (18) is in power transmission with the garlic seeding device transmission shaft (15).

8. The garlic seeder of claim 7, wherein: the rear end of the rack (1) is provided with an operating platform, the operating platform comprises a foldable pedal (20) and an armrest (21), and a main clutch operating handle (23) and an auxiliary clutch operating handle (22) are mounted on the armrest (21).
