Description

Technical Field

[0001] The utility model relates to the technical field of seedling tray seeders, in particular to a feeding and mixing mechanism of a seedling tray seeder. Background Art

[0002] A seeder is a planting machine that sows crop seeds. A seeder used for a certain type of crop is often named after the crop type, such as a grain drill, corn hole seeder, cotton seeder, forage spreader, etc. A seedling tray seeder requires a feed mixing mechanism to mix the crops being sown.

[0003] For example, the feeding and mixing mechanism of a seedling tray seeder with the authorization announcement number "CN217336837U" includes peat soil feeding, perlite feeding and a mixed material feeding trough. A feeding hopper is opened on the side of the perlite feeding trough to facilitate feeding operation and save labor. A movable baffle is added to the mixed material feeding trough to adjust the feeding amount and feeding speed, thereby reducing the machine failure rate. However, the feeding and mixing mechanism of the seedling tray seeder controls the position of the partition through a spring, but the spring will always rebound during use, which causes the position of the positioning column to be unfixed, which causes the position of the partition to be unable to be fixed, thereby reducing the working quality of the feeding and mixing mechanism. At the same time, the feeding and mixing mechanism of the seedling tray seeder requires the operator to manually measure the dosage of the raw materials to be added, which increases the workload of the operator. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the spring will always rebound when in use, which causes the position of the locking column to be unfixed, which causes the position of the partition to be unable to be fixed, which reduces the working quality of the feeding and mixing mechanism and requires the operator to manually measure the dosage of the raw materials to be added, which increases the workload of the operator, and a feeding and mixing mechanism for a seedling tray seeder is proposed.

[0007] Preferably, the material blocking device includes a motor, the outer wall of the motor is fixedly connected to the first shell through a bracket, the output shaft of the motor is fixedly connected to two first connecting rods, the outer walls of the two first connecting rods are fixedly connected to the internal gear, the outer wall of the internal gear is meshed with two gears, the outer walls of the two gears are fixedly connected to the threaded rod, the outer walls of the two threaded rods are threadedly connected to the nut, and the outer wall of the nut is fixedly connected to one end of the second connecting rod.

[0008] Preferably, the other end of the second connecting rod is fixedly connected to the baffle, and the outer walls of the two gears are rotatably connected to the first housing via a pin.

[0009] Preferably, the quantitative feeding device includes a second shell, the outer wall of the second shell is fixedly connected to the mixer body, the outer wall of the second shell is slidably connected to the slider through a slide groove, the outer wall of the second shell is fixedly connected to the feed port, the outer wall of the slider is fixedly connected to the moving box, the outer wall of the moving box is fixedly connected to the cross plate, the outer wall of the cross plate is slidably connected to the second shell, and the outer wall of the second shell is fixedly connected to the discharge ramp.

[0010] Preferably, the outer walls of the two nuts are slidably engaged with the first shell via a sliding groove, and the outer walls of the two threaded rods are rotatably connected with the first shell via a bearing.

[0011] Preferably, the outer walls of the two second connecting rods are slidably connected to the first shell through a through hole, and the outer walls of the two second connecting rods pass through the first shell through the through hole.

[0012] The utility model proposes a feeding and mixing mechanism of a seedling tray seeder, which has the beneficial effects that: through the cooperation of the first shell and the material blocking device, the motor drives the first connecting rod to rotate, the first connecting rod drives the internal gear to rotate, the internal gear drives the gear to rotate, the gear drives the threaded rod to rotate, the threaded rod drives the nut to move, the nut drives the second connecting rod to move, the second connecting rod drives the baffle to move, the baffle descends to separate the two sides of the feed hopper, and the above method can prevent too much raw material from entering the mixer body, thereby improving the working quality of the feeding and mixing mechanism.

[0013] Through the cooperation of the mixer body and the quantitative feeding device, the slider drives the moving box to move, and the moving box drives the raw materials inside to the top of the discharge ramp. Then the raw materials fall on one side of the baffle in the feed hopper through the discharge ramp. The moving box drives the cross plate to move at the same time, and the cross plate blocks the feed port to prevent the raw materials from continuing to fall. Then the operator resets the slider and repeats the above operation until enough raw materials are added. The above method does not require the operator to measure the raw materials, which reduces the operator's workload. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Working principle:

[0027] When the materials added to the seedling tray seeder need to be mixed through the feeding and mixing mechanism:

[0028] Feeding stage:

[0029] First, the operator pours enough raw materials into the feed port 703, and then the raw materials fall into the movable box 705 through the feed port 703. Then the operator pulls the slider 702, and the slider 702 drives the movable box 705 to move. The movable box 705 drives the raw materials inside to the top of the discharge ramp 706.
