Abstract

The utility model relates a rice seedling-throwing seeder, comprising a seed separating box and a seed measurement screen. The seed measurement screen is inserted into the seed separating box via the passage at the bottom of the end face of the seed separating box, and stably locked in a chute of the seed separation box that corresponds with a reservation adjustment lock in the seed measurement screen via bolts. In this way, corresponding sliding and cooperation can be performed, and meanwhile, the seed measurement screen is closely fixed to the bottom of the seed separation box. The adjustment lock hole can satisfy requirements of various seeding types. The seed separation box is of upper open-end style. A handle is mounted at the upper section of the end face. The bottom section of the end face is a passage. Limitation cards are provided on the two sides of the interior bottom. A seed separation hole (square style with two round ends) that corresponds with the seedling nursery pot in the seedling-throwing tray is positioned at the bottom. The bottom of the seed separation box is provided with positioning legs that at the same taper with the seedling nursery pot, with hollow style, and the bottom of the positioning legs are provided with strengthened rib stiffeners which form an angle with the boundary rafter. In the seed measurement screen, a square distribution hole with two round ends that corresponds to the seed separation hole is provided so that dropping of rice grain can be satisfied. An action handle is provided at one end of the seed measurement screen.

Description

The rice seedling throwing disc seeding device

Technical field

The utility model relates to a kind of rice seedling throwing disc seeding device, makes with the engineering plastics injection moulding.

Background technology

The present agricultural rice of China has adopted the rice transplanting mode, and the rice transplanting seedling-cultivation technique adopts the rice transplanting dish to cultivate, and this has just brought the evenly problem of sowing of rice transplanting plate seedling raising, and artificial direct evenly sowing is trouble very: 1, waste seed; 2, workload is big; 3, uneven sowing is even.

Technical scheme

The purpose of this utility model is to provide a kind of rice seedling throwing disc seeding device, is equipped with in evenly sowing in the rice transplanting dish, and rice shoot is even when helping the land for growing field crops rice transplanting simultaneously.

In order to achieve the above object, the utility model is to realize like this, the rice seedling throwing disc seeding device is become with amount kind of a screen banks by seed leaking box, amount kind of sieve inserts in the seed leaking box by the port of seed leaking box end face below, regulating lock hole with the reservation on the bolt throughput kind sieve is locked in the chute of seed leaking box correspondence, form and be slidingly matched mutually, in satisfied simultaneously amount kind of a sieve is close at the bottom of the seed leaking box, the transposing lock hole is applicable to the different cultivars requirement of seeding, seed leaking box is that upper shed is box-like, the end face top is provided with handle, seed leaking box end face below be a port, and there is the spacing card of correspondence on inside bottom two limits, the bottom have with the rice transplanting dish on the corresponding two end semicircle rectangle seed leaking holes of seedling alms bowl, the seed leaking box bottom is corresponding to be provided with and the angle of rice transplanting plate seedling raising alms bowl with tapering, hollow type, bottom have the reinforcement that intersects that becomes angle with the limit rafter, have the rectangular profile hole with two end semicircles of seed leaking hole correspondence on amount kind of the sieve, fall and be as the criterion to satisfy the grain of rice, amount kind of sieve one end is provided with the action handle.

The utility model has the advantages that simple to operate, evenly sowing has improved speed of drilling.

Description of drawings

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

Fig. 1 looks schematic diagram for the master of the utility model seed leaking box;

Fig. 2 is the elevational schematic view of the utility model seed leaking box;

Fig. 3 looks the cutaway view of schematic diagram A-A position for the master of the utility model Fig. 1 seed leaking box;

Fig. 4 is the schematic rear view of the utility model seed leaking box;

Fig. 5 looks schematic diagram for the master of the utility model amount kind sieve;

Among the figure: 1, seed leaking hole; 2,9, spacing card; 3, chute; 4, handle; 5, seed leaking box; 6, seed leaking box mouth reinforcement; 7, port; 8, angle; 10, intersection reinforcement; 11, sieve kind of hole; 12, lock hole; 13, amount kind of sieve; 14, amount kind of sieve handle.

Specific implementation method

Fig. 1 Fig. 2 Fig. 4 is a seed leaking box 5, Fig. 3 looks the cutaway view of schematic diagram Figure 1A-A position for the master of seed leaking box 5, seed leaking box 5 is box-like for upper shed, seed leaking box 5 is box-like for upper shed, the end face top is provided with handle 4, seed leaking box end face below is a port, there is corresponding spacing card 2 on inside bottom two limits, 9, the bottom have with the rice transplanting dish on the corresponding two end semicircle rectangle seed leaking holes 1 of seedling alms bowl, seed leaking box 5 bottom correspondences are provided with and the angle 8 of rice transplanting plate seedling raising alms bowl with tapering, hollow type, the bottom have become angle with the limit rafter intersect reinforcement 10, leave the chute 3 of vertical direction in the middle of seed leaking box 5 bottoms, seed leaking box is provided with seed leaking box mouth reinforcement 10 for 5 mouthfuls.

Fig. 5 is amount kind of sieve 13, its length is greater than the length of seed leaking box 5, amount kind of sieve have on 13 with seed leaking box 5 on the sieve kind hole 11 of two end semicircle rectangular profile of seed leaking hole 1 correspondence, fall and be as the criterion to satisfy seed, amount kind of sieve leaves the corresponding adjusting lock hole 12 of chute in the middle of vertical direction and seed leaking box 5 bottoms 3 in the middle of 13, and the end design amount of the having kind of amount kind of sieve 13 is sieved handle 14.

Operation sequence is: will measure kind of sieve 13 and insert in seed leaking box 5 ports 7, be locked in the chute 3 of seed leaking box 5 correspondences with the adjusting lock hole of reserving on the bolt throughput kind sieve 13 12, form and be slidingly matched mutually, satisfy amount kind of a sieve 13 simultaneously and be close to seed leaking box at 5 the end, because the length of amount kind of sieve 13 is greater than the length of seed leaking box 5, spacing by regulating lock hole 12 and chute 3 again when coming and going sowing, can not take off head, just become the utility model, twitch or push-in stroke kind sieve 13 makes sieve kind of hole 11 stagger with seed leaking hole 1 during use, again the grain of rice is packed in the utility model, be placed on the rice transplanting dish, since the effect of angle 8, seed leaking hole just in time with the rice transplanting dish on the seedling alms bowl corresponding, require to realize evenly sowing number according to sowing toward inverse kind sieve 13.
