Problems solved by technology

The common forms mainly include toothed conveyor belt type, guide rail plate type, stop pin type, tray feeding type, etc. Among them, the toothed conveyor belt type and guide rail plate type belong to manual seedling separation, which can be applied to seedlings or bare seedlings, and the speed and accuracy of seedling separation The stability depends on the situation of manual seedling feeding; the stop pin type and the tray feeding type are suitable for automatic seedling separation of seedlings, and have high requirements for the standing stability of the seedlings. In the process of seedling separation, it is easy to cause pot damage and stem breakage, and it is difficult to ensure vertical feeding. The tray feeding type belongs to disorderly separation of seedlings. The seedlings are crowded with each other and it is difficult to ensure the feeding of seedlings. The accuracy of seedling separation is low. The bowl also does some damage
To sum up, the existing automatic seedling separation device still needs to improve the accuracy of seedling injury and seedling separation, and the manual seedling separation has defects such as low work efficiency and high labor intensity.

Embodiment 1

[0034] The transplanting machine of the present embodiment transports the seedling separation system, such as Figure 1-9 Shown, comprise the frame 1 that is hooked on the tractor and be installed on the frame 1 into row seedling conveying device 6 and automatic seedling sorting device 5.

[0035] like figure 1As shown, the frame 1 is provided with an intermediate shaft 17, and the power of the tractor output shaft is transmitted to the intermediate shaft 17 through the power input shaft through the chain, and the intermediate shaft 17 is driven to form a seedling discharge conveying device 6 and an automatic seedling separating device 5 respectively. Action; automatic seedling-separating device 5 and row seedling conveying device 6 are arranged on the rear of frame 1; In this example, both the front and the rear are based on the motion direction of the rice shoots, that is, the rice shoots move from the rear to the front. The frame 1 is provided with four ground wheels 104,...

Embodiment 2

[0044] This embodiment is an improvement on the basis of Embodiment 1. The difference from Embodiment 1 is that in Embodiment 1, the fixed side conveyor belt and the movable side conveyor belt can be driven separately by motors; but this embodiment preferably use Figure 9 The driving scheme shown: the wide gear drive sprocket 410 and the conveyor belt drive sprocket 424 are simultaneously driven by the power drive wheel 318, the wide gear drive sprocket 410 drives the gear shaft to rotate, and the two ends of the wide gear shaft are respectively located on two sides of the conveyor belt. The first wide gear 416 and the second wide gear 422 on the side, the first narrow gear shaft corresponding to the first wide gear 416 is provided on the parallel link frame, and the first narrow gear shaft corresponding to the second wide gear 422 is provided on the frame 1 Two narrow gear shafts, the first and second narrow gear shafts are provided with narrow gears 417, 421 matched with th...

Abstract

The invention relates to a seedling conveying and sorting system of a transplanter. The system comprises a rack, a row seedling conveying device and an automatic seedling sorting device, wherein a movable baffle plate is arranged at one side of a rear conveyor belt in the row seedling conveying device, and is driven to turn over by means of a first cylinder; the automatic seedling sorting device synchronously drives the translation of a parallel connecting rod frame and the rotation of a shifting fork by means of a second cylinder; an air compressor is installed on the rack; the air compressorsynchronously drives the first cylinder and the second cylinder by means of a reversing valve. The seedling conveying and sorting system of the transplanter can enable the seedlings to be conveyed ina way of standing in rows and divided according to a certain beat, thus realizing accurate seedling taking and planting.

Description

technical field [0001] The invention relates to a transplanting machine conveying and separating seedling system, which belongs to the technical field of agricultural machinery. Background technique [0002] Vegetable mechanized transplanting can shorten the vegetable growth cycle and increase yield, and has gradually become the main production mode of vegetable cultivation. In order to improve work efficiency, reduce labor intensity, and realize automatic and rapid vegetable transplanting, the key lies in how to continuously transport the seedlings by machines instead of manual labor and put them into the seedling separation mechanism, which is called automatic seedling transporting technology. [0003] At present, the common seedling transportation methods include three types: seedling guide tube type, double-disc clamping type and belt type transportation. Among them, the tube type transport uses a planter to put the seedlings above the seedling guide tube, and the seedli...
