Abstract

The utility model relates to a pneumatic rice soil-block seedling throwing machine composed of a dynamic chassis, a feeding device, a seedling dividing mechanism and a throwing device. The utility model adopts the pneumatic throwing principle and simulates manual throwing procedure. When throwing seedling, the pneumatic rice soil-block seedling throwing machine has no mechanical action on pot seedlings without damaging seedlings or pot bodies, and both the throwing height and the angle are adjustable; consequently, the pot seedlings thrown out drop into deep soil with good distribution uniformity and uprightness. The working radius of throwing seedlings reaches 3.5 to 4.5 meters. The utility model raises seedling throwing quality and reduces cost obviously.

Description

Pneumatic type accurate rice pot seedling throwing transplanting machine

The utility model is a kind of pneumatic type accurate rice pot seedling throwing transplanting machine that is used for the operation of accurate rice pot seedling rice transplanting.

The rice seedling throwing technology is to develop in recent years to improve, the practical new technology of the laborsaving cultivation of rice high yield that state key is promoted.Though at present existing several throwing transplanting machines are developed, and get rid of disc type throwing transplanting machine etc. as circular cone, there is following problem in existing throwing transplanting machine: the one, and the rice transplanting process realizes the mechanism of seedling in earthen bowl by workpiece, therefore hinders seedling, broken alms bowl body problem is serious; The 2nd, the machinery work of separating seedlings or planting is unreliable, still is in conceptual phase, and artificial feeding causes the rice transplanting inequality; The 3rd, rice transplanting height deficiency, the rice transplanting angle is little and can not adjust, and makes that burying of rice shoot is bad with orthostatic.

The purpose of this utility model is to design a kind ofly to match with the minitype motivation chassis, meet agriculture requirement efficient height, power consumption is little, simple in structure, cost is low, easy to utilize accurate rice pot seedling throwing transplanting machine, to solve the artificial at present problem that rice transplanting is of poor quality, farming season season is nervous, promote the development of China's Rice Production.

The purpose of this utility model is achieved in that it comprises that power chassis, transmission device, feeding device, seedling-distributing mechanism, throwing send device and frame, the deck of boat etc., is characterized in that:

(1), the parallel driven cylinder of drive roll of feeding device, suit seedling sending band on two cylinders is arranged equidistantly the seedling dish locating detent of truncated rectangular pyramids shape on the seedling sending band;

(2), the cylinder axis of the parallel feeding device of axis of the roller of pulling up seedlings of seedling-distributing mechanism, and be bearing on the support by bearing; On the roller of pulling up seedlings, be fixed with and decide the seedling folder, and the moving in axial sliding seedling of assembling presss from both sides on the roller of pulling up seedlings; The end face push pedal is fixed on the frame, and the platen cover that is positioned under the roller of pulling up seedlings is fixed on the frame, and the platen cover is a semiarc shape, and its upper end is provided with presser feet;

(3), throw and to send the centrifugal blower exit of device to be connected with acclivitous variable cross-section rectangular air duct, be connected with in the upper end of airduct to throw and send groove.

The utility model has the advantages that: simulate artificial rice transplanting process, adopt strength to throw and send principle, the rice transplanting process does not act mechanically on pot seedling, no seedling injury, not broken alms bowl body, and rice transplanting height and the angle of dishing out be adjustable, makes the seedling in earthen bowl embedded depth of dishing out and distributing homogeneity and orthostatic good, and the rice transplanting working width can reach 3.5-4.5 rice, the similar machine with other of the utility model is compared, the rice transplanting quality is greatly improved, and the also corresponding decline of its cost is convenient to promote the use of.

Describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model general illustration.

Fig. 2 is the seedling dish locating detent distribution map on the seedling sending band.

Fig. 3 is the seedling-distributing mechanism view.

Fig. 4 is the A-A cutaway view of Fig. 3.

See shown in Fig. 1-4, concrete structure is as follows: the frame 14 that on the deck of boat 11, is fixedly connected, rotate connection driving and driven cylinder 10 and 3, suit seedling sending band 4 on driving and driven cylinder 10 and 3 by bearing on the frame 14, on seedling sending band 4, arrange three rows equidistantly, the seedling dish locating detent 15 of truncated rectangular pyramids shape; Be provided with the roller 18 of pulling up seedlings above drive roll 10, the roller 18 of pulling up seedlings is rotatably connected on the frame 14, is fixedly connected on the roller 18 of pulling up seedlings to decide seedling folder 6; The fixing card 16 of pressing on the roller 18 of pulling up seedlings is pressed the slide bar that installs moving seedling folder 7 in the card 16, and moving seedling folder 7 axially slides in pressing card 16 by slide bar, and an end of slide bar is screwed the bulb nut, is set with back-moving spring 17 on the slide bar; Be positioned at affixed end face push pedal 5 on the frame 14 of slide bar one end, jagged in the end face push pedal 5, when the roller 18 of pulling up seedlings rotates, slide in end face push pedal 5 slide bar end on it, when the roller of pulling up seedlings turns to the seedling folder with the rice shoot upright position, breach in the end face push pedal 5 loses the push-tight effect to moving seedling folder 7, and moving seedling folder 7 makes, decides the seedling folder and clamps under action of reset spring.Give stroke and the chucking power that tight power changes moving seedling folder 7 by rotating the bulb nut and changing spring.Moving seedling folder 7 clamps rice shoot with deciding seedling folder 6, thereby rice shoot is pulled up from seedling sending band 4.In the bottom of frame 14 blower fan 13 that is driven by engine 12 is installed, is connected variable cross-section rectangular air duct 9 at blower fan mouth place, connect to throw in the upper end of airduct and send groove 8.When power chassis 1 driving throwing transplanting machine advanced, its power drove drive rolls 10 by transmission device 2 and roller 18 work of pulling up seedlings, and makes seedling-distributing mechanism work, and meanwhile, the pot seedling under rice seedlings transplanter divides seedling-distributing mechanism send groove to throw in the air by throwing.
