Problems solved by technology

[0003] The double crank mechanism and the planetary gear mechanism can only form a ring-shaped track, but cannot realize a double-ring track. It is difficult to ensure a better posture to enter the seedling planting work part and realize the full automation of the flower transplanter. In order to solve this problem, it is necessary to A ring-shaped track is also designed in the seedling planting mechanism to meet the requirements of the flower transplanting track

Embodiment Construction

[0030] The present invention will be further described below in conjunction with drawings and embodiments.

[0031] The design method of the two-degree-of-freedom variable crank five-bar drive mechanism to form the transplanting trajectory, the specific steps are as follows:

[0032] Step 1: Construct the variable crank five-bar drive mechanism.

[0033] Such as figure 1 As shown, the variable crank five-bar driving mechanism includes a first crank 1, a first connecting rod 2, a second crank 4, a second connecting rod 5, a sliding sleeve 6, a rotary motor and a linear motor; one end of the first crank 1 is connected to The frame 3 is hinged, and the other end is connected with the sliding sleeve 6 through a sliding pair; one end of the first connecting rod 2 is hinged with the sliding sleeve 6, and the other end is hinged with one end of the second connecting rod 5; one end of the second crank 4 is connected with the frame 3 is hinged, and the other end is hinged with the mi...

Abstract

The invention discloses a design method for forming a transplanting track by using a length-variable crank five-rod driving mechanism with two degrees of freedom. The existing transplanting mechanism track is not suitable for transplanting flowers. The design method comprises the following concrete steps of firstly, establishing the five-rod driving mechanism with a changing crank, and establishing a mathematic model of a double-buckle transplanting track formed at the end point of the free end of a second connecting rod; then, carrying out reverse solving of the length changing rule of a first crank through the established mathematic model, and calculating the sliding speed of a sliding sleeve on the first crank; and finally, checking whether the five-rod driving mechanism with the changing crank meets the existing condition of double cranks. The double-buckle transplanting track is achieved by using the five-rod driving mechanism with the changing crank, so that not only can the transplanting tracks of flowers be achieved, but also the fully-automatic transplanting of various crops such as melons, fruits, vegetables and flowers can be realized.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and relates to a design method for flower planting tracks, in particular to a design method for forming a transplanting track by a two-degree-of-freedom variable crank five-rod driving mechanism. Background technique [0002] Mechanized transplanting is generally divided into two steps: taking seedlings and planting. According to different ways of taking seedlings, the transplanting machine is divided into two modes: fully automatic and semi-automatic. The key sign is to see whether it uses mechanized seedling picking. At present, there are two ways of picking seedlings by mechanical transplanting in dry land and picking seedlings by clamping seedlings. The new planetary gear system rotary seedling picking mechanism includes a hybrid high-order modified elliptical gear planetary system seedling transplanting machine, a free second-order non-circular gear planetary system high-speed pot seed...
