Description

Seedling lifting swing type soil removing device

Technical Field

The utility model belongs to forestry machinery, and mainly relates to a vibration soil removing device of a seedling lifter.

Background

The big seedlings are divided into two types of seedlings with soil and seedlings without soil, generally speaking, deciduous broad-leaved trees are not covered with soil when seedlings are raised, and evergreen tree species including coniferous trees and broad-leaved trees are covered with soil. The working process of the existing seedling lifter for lifting seedlings of deciduous broad-leaved trees comprises seedling lifting and soil shaking, a large amount of labor is needed for subsequently picking the seedlings and the whole seedlings, and the lifted seedlings have the phenomenon that the actual condition of root-soil separation does not meet the specific production requirement condition, so that a vibration soil removing mechanism which can be arranged below a conveying device of the seedling lifter is developed, the problem that the seedling root-soil separation is not thorough in the seedling lifting process can be well solved, the vibration frequency of the root-soil separation can be adjusted in multiple stages, the actual condition of the root-soil separation can meet the specific production requirements of each stage of seedling lifting, collection, arrangement, storage, transportation and transplantation, and the seedling lifter has important practical significance and a certain market application scene.

Disclosure of Invention

The utility model aims to solve the specific problems in the prior art, and researches and designs a seedling lifting vibration soil removing device, through the design of a vibration soil removing mechanism arranged below a conveying mechanism of a seedling lifter, the vibration soil removing can be completed in the seedling lifting process, meanwhile, the vibration frequency can be flexibly adjusted in multiple stages according to different production requirements and actual working conditions, and through the design of an adjustable fastening screw and a replaceable swing rod on a cam connecting frame, the vibration soil removing device can vibrate and peel off the soil at the root of a seedling through the swing of the swing rod, so that the aim of vibrating and shaking the soil is fulfilled.

The technical scheme adopted by the utility model is as follows: the utility model provides a play seedling vibration and take off native device, includes that external power driven transmission gear axle and cam pass through ball bearing and install on the connecting plate, and the cam rotates and carries out reciprocating motion with ball bearing under the restraint of elastic webbing, and adjustable link span and T type frame are connected through adjustable position's fastening screw, and T type frame drives the pendulum rod swing under the restraint of locating pin, constitutes a play seedling vibration and takes off native device so far.

The utility model has the beneficial effects that: the utility model has simple mechanism, convenience and practicability, and small occupied space and volume when being arranged under the conveying mechanism of the combined seedling lifter. Can carry out multistage adjustment according to different operational environment, root soil bonding condition and the actually required root soil separation effect, through changing pendulum rod quantity, adjust root soil separation efficiency by a wide margin, change the reciprocating motion stroke of cam and ball bearing motion through the adjustable fastening screw of fine setting, change vibration frequency, reach and finely tune nursery stock root soil array appearance separation effect. So as to meet the requirements of different collection, arrangement, transportation and transplantation after seedling lifting. Simultaneously the utility model has the advantages of novel in design, strong adaptability, reliability are high.

In the figure: 1. swing rod 2, transmission gear 3, transmission shaft 4, bearing block 5, bolt hole 6, ball bearing 7, connecting plate 8, connecting frame 9, elastic band 10, cam 11, shaft 12, ball bearing 13, adjustable connecting frame 14, fastening screw 15, T-shaped frame 16 and positioning pin

Detailed Description

Embodiments of the present invention are described in detail below with reference to the accompanying drawings:

according to the arrangement, when the vibrating soil cleaning device works, the speed reducer drives the transmission gear 2 to provide power, the transmission shaft 3 drives the cam 10 fixedly arranged on the transmission shaft to move in a full circle, the cam 10 drives the ball bearing 12 to move in a reciprocating mode to form a driving part of the whole unit, the elastic belt 9 restricts the maximum reciprocating stroke of the cam 10 and the ball bearing 12, the cam 10 and the rolling bearing 12 arranged on the adjustable connecting frame 13 move in a reciprocating mode to drive the T-shaped frame 15 arranged on the positioning pin 16 to swing under the restriction of the positioning pin, and the swing rod 1 connected to the T-shaped frame 15 also swings along with the T-shaped frame. When the combined seedling lifter works, the swing rod 1 swings and continuously strikes the seedling roots on the combined seedling lifter conveying device, so that soil at the seedling roots is vibrated and peeled off, and the purpose of vibrating and shaking the soil is achieved. When the seedling planting machine does not work, the root of the seedling just falls between two adjacent swing rods, the connecting line of the axes of the seedling is parallel to the axes of the swing rods, and the plane formed by the two straight lines is vertical to the ground. After the seedling planting machine starts to work, the speed of the swing rod is the minimum at the two limit points, the speed is the fastest when the swing rod returns to a position right below a seedling, the force generated by the swing rod is the maximum, the soil shaking capability is the strongest, and therefore root-soil separation is achieved thoroughly.

The installation number of the swing rods can be determined according to the adhesion condition of the seedling environment and the root soil, the more the swing rods are, the better the root soil separation effect achieved by the vibration soil shaking device is, and the larger the power correspondingly required to be provided by the speed reducer is. Different swing rods are selected according to the binding power of the root soil, the number of the swing rods arranged on the swing rod seat is respectively 2, 4 and 6, and finally the separation efficiency of the root soil can reach 80-95%. According to specific working environment conditions and actual required soil removal requirements during working, the reciprocating stroke in the actual working process can be finely adjusted by adjusting the fastening screws on the adjustable ball bearing frame, so that the vibration effect of the vibration soil removal device is finely adjusted. For the vibration soil removing device for the existing combined seedling lifter, the vibration soil removing device is arranged below the transmission device of the combined seedling lifter through the connecting plate, and the space occupied by the driving part is small in volume. Therefore, the vibration soil removing device for the combined seedling lifter realizes that the soil at the root of the seedling is vibrated to be peeled off through swinging of the swing rod, and the purpose of vibrating and shaking the soil is achieved.
