Problems solved by technology

Although its picking efficiency is high, there are certain problems: 1), it is not easy to determine the suitable cutting speed
When the cutting speed is too small, there is a phenomenon that the stems are missed. When the cutting speed is too high, the noise and vibration of the picking table are too large, which affects the normal operation of the picking machine; New spores are produced in different positions, and the spores will be damaged when harvested with this picking device, resulting in failure to bear new fruits in the second year; 3), oil peony plants of different varieties and different origins have different growth heights, stem thicknesses, and stalk thicknesses. and the number of branches and leaves make the picking device unsuitable for general use; 4), the picking platform is mainly aimed at plain planting conditions for large-scale harvesting operations, and is not suitable for hilly areas and small-area operations

Embodiment 1

[0142] Two acres of oil peony plants are picked and processed with the oil peony fruit picking machine provided by the invention, comprising the following steps:

[0143] 1) According to the size of the peony plants to be picked for oil described in Table 1, the number of sleeves of the peony fruit picking machine for oil is set to 11, and the distance between each pair of comb teeth in the axial direction is designed to be 60 mm. The material used for the comb teeth is No. 45 steel;

[0159]

[0160] As can be seen from Table 2, compared with Comparative Example 1, the picking amount of peony fruit for oil in Example 1 has increased by 15.93% on average, the picking rate has increased by 15.87% on average, the fruiting rate in the next year has increased by 9.10% on average, and the plant damage rate has increased by an average of 15.87%. A reduction of 47.62%.

[0161] In summary, using the picking machine provided by the invention to pick peony fruits for oil can increase the picking rate up to 74.9%, the damage rate down to 5.6% at the lowest, and the fruiting rate in the next year up to 90.7%.

Abstract

The invention discloses a picking machine and picking method for fruit of Paeonia suffruticosa. The picking machine comprises a combing device (2) and a steering device (3), wherein the combing device(2) is arranged in a horizontal direction, and comprises a combing-off shaft (21), sleeves (22) and clamping members (23), the sleeves (22) and the clamping members (23) are arranged at intervals onthe combing-off shaft (21), the sleeves (22) are reciprocally slidable on the combing-off shaft (21), and the outer walls of the sleeves (22) are provided with comb teeth (24) with hook-shaped top ends and linear root portions. The picking machine of the invention not only can adjust the spacing by itself during a picking process, but also can realize only combing off fruit without damaging plants.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a peony fruit picking machine for oil and a picking method thereof. Background technique [0002] Peony for oil is a small perennial shrub native to my country. The peonies for oil grown in China are mainly Fengdan, purple spot and other varieties. When the fruit is not fruited, the plant grows upright. After fruiting, due to the weight of the fruit, the branches are bent , at this time the fruit-bearing stalks are randomly distributed. [0003] In recent years, the planting of peonies for oil has been promoted on a large scale in Shandong, Henan, Shaanxi and parts of Hebei in my country, and the enthusiasm of the growers is very high. However, at present, the picking of peony fruits relies on manual work, which is labor-intensive and has low harvest efficiency. Harvesting costs are relatively high and it is difficult to meet the agronomic requirements; moreover, th...
