Abstract

The utility model relates to a portable fertilizing and seeding machine for the crops of plant division. The utility model is composed of a barrel cover 1, a barrel body 2, a handle 3, a foot pedal lever 4, a sowing quantity limiting device 5, a duck mouth type injecting head 6 and a drive mechanism. The utility model is characterized in that the injecting head is composed of a wedge-shaped long duck mouth device 61 and a wedge-shaped short duck mouth device 62; a connecting rod 8 which can move upwards and move downwards is arranged in the barrel body 2; both the short duck mouth device 62 and a self-closing valve 12 are connected with the connecting rod 8. When the connecting rod moves downwards, the self-closing valve is closed while the short duck mouth device is opened, and then certain quantity of fertilizer or seed is downwards injected into the soil; when the connecting rod is reset, the short duck mouth device is closed while the self-closing valve is opened, and the fertilizer or the seeds enter the injecting head. The fertilizing and seeding machine has the advantages of rapid seeding speed, rapid fertilizing speed, uniform fertilizing quantity, labor saving, small volume, light weight and portability.

Description

Portable sowing & fertilising device for each plant

The utility model is a kind of portable plant division crop fertilization, seeder, relates to agricultural machinery technological field.

Existing duck-beak type head fertilising, seeder, its head is made up of two isometric duckbilleds, and such head inserts when applying fertilizer in the earth, because of contact-making surface is bigger, effort, and because of fertile without limits mechanism of measuring in the fertilizing and seeding apparatus, therefore fertilizing amount is inhomogeneous, and transmission mechanism is also complicated.

The purpose of this utility model is to improve existing duck-beak type head fertilizing and seeding apparatus, makes it laborsaving, and fertilizing amount is even, and structure is simpler.

The purpose of this utility model is to realize like this, in the staving termination that stores fertilizer the one fixed long duckbilled that is wedge shape is set, and connection short duckbilled thereon, form the head that applies fertilizer by long and short duckbilled, is provided with a connecting rod along the staving direction in the staving, this connecting rod is connected with joint door, the weak point duckbilled of the fertile amount of restriction, when connecting rod moves downward, just drive joint door is closed and is promoted short duckbilled and opens, and the quantitative fertilizer between this time door and short duckbilled is just exported by the duckbilled head; Otherwise short duckbilled is closed when connecting rod moves upward, and stops fertilising simultaneously, and the joint door is opened, and fertilizer is entered the duckbilled head by the joint door, so moves up and down connecting rod, can realize the fertilising of equal and quantitative; And transmission mechanism directly drives the joint door by the manual operating connecting rod and short duckbilled is comparatively simple, so compact conformation; The two not isometric duckbilleds of head in addition, wedge shape structure with long duckbilled, make the long duckbilled of wedge shape insert in the soil earlier, since wedge shape while be vertical be the oblique angle, it than original two sides all be the head at oblique angle will be laborsaving many, and such structure is lacked the open angle [alpha] of duckbilled in the same distance L of opening ₁Than the open angle [alpha] of original duckbilled ₀Want big, i.e. α ₁＞α ₀(see figure 1), thus make the velocity ratio of this fertilizing and seeding apparatus want fast originally, and efficient improves.

The utility model has the advantages that: it is laborsaving that head enters soil, and fertilizing amount is even, high efficiency, and transmission mechanism is simple, and compact conformation is made easily, and easy to operate, cost is low.

With drawings and Examples structure of the present utility model is done further narration below:

Fig. 9 is the utility model running status one.

Figure 10 is the utility model running status two.

Be labeled as among the figure: 1. bung, 2. staving, 3. handle, 4. pedal rod, 5. sowing stopper, 6. duck-beak type head, 61. long duckbilled, 62. short duckbilleds, 63. bearing pins, 7. restrictor bar, 8. connecting rod, connecting hole on 81,82,83. connecting rods, 9. core wheel, 10. spring, 11. backing pins, 12. joint doors, 13. bearing pins.

By visible this fertilizing and seeding apparatus in Fig. 1～4 by bung 1, the termination is the staving 2 of cone-shaped, handle 3, foot-driven lever 4, sowing stopper 5, duck-beak type head 6, and transmission mechanism is formed, it is characterized in that being provided with a connecting rod 8 that links to each other with restrictor bar 7 along the staving direction in the staving 2, the cone segments of staving 2 links the long duckbilled 61 of a wedge shape, it be connected short duckbilled 62 on it with bearing pin 63 and match and form head 6, on the heart wheel 9 of connecting rod 8 one end bearings in staving 2, and its termination links to each other with operation restrictor bar 7, restrictor bar can rotate around bearing pin 13, another top of connecting rod 8 is connected with short duckbilled 62, from the suitable distance in this top, connecting rod 8 is connected with joint door 12, and corresponding joint door tip position place is provided with a backing pin 11 on long duckbilled 61; When connecting rod moved downward, connecting rod 8 promoted short duckbilled 62 and opens the duckbilled fertilising around bearing pin 63 rotations, and meanwhile, connecting rod 8 drives joint door 12, cause has backing pin 11 to stop that joint door 12 can only rotate, and to the closed position, otherwise connecting rod moves upward, short duckbilled closure, the joint door is opened, and fertilizer enters duckbilled.

By Fig. 2～5 as seen, the hole 81,82,83 that connecting rod 8 is provided with is for being connected used with operation restrictor bar 7, joint door 12, short duckbilled 62 respectively, hole 621 on hole 611 that long duckbilled 61 is provided with and the short duckbilled matches, and to pass by bearing pin 63 that this two hole connects be a head 6, another hole 612 on the long duckbilled 61 is used for dress shelves pin 13, hole 121 on the joint door 12 is complementary with the hole 82 on the connecting rod 8, will save 12 with connecting piece by this and link to each other with connecting rod 8.

By Fig. 1,9,10 as seen, when operating personnel apply fertilizer, hold in handle earlier buries this fertilizer applicator straight cutting, one draw then slightly backward, soil is just uncovered a nest, and meanwhile, hand is pinched restrictor bar 7, restrictor bar 7 just rotates around bearing pin 13, and drivening rod 8 moves downward, and connecting rod 8 just promotes short duckbilled 62 and rotates around bearing pin 63, and short duckbilled 62 opens, meanwhile connecting rod 8 is being with joint door 12 to rotate and will save door 12 and close (see figure 9) around backing pin 13, this, fall in the native median fovea once closing envoy's door to the quantitative fertilizer between head, otherwise, with the openhanded bar 7 of opening a sluice gate, connecting rod 8 is moved upward, short duckbilled 62 is closed, and joint door 12 is just opened, and fertilizer just enters head once more in the bucket 2, transfer to fertilizer applicator then, loosening the soil on the head with regard to automatic topped fertile nest.This shows that this fertilizing and seeding apparatus is easy to operate, fertilizing amount is even, compact conformation, and volume is little, and is in light weight, moves easily, applied widely, all applicable to level land, hilly ground, hillside.

(referring to Fig. 1) is provided with a spring 10 in the present embodiment on connecting rod 8, connecting rod 8 moves down with hand operated restrictor bar 7 and realizes, spring 10 by compression at this moment, returning then of connecting rod can be finished by the elastic force of spring 10, like this during ferti-seeding, the bar 7, one of need only one applying the handbrake is let go to pinch and got final product, and is easy to operate, and laborsaving.As seen from the figure, sowing used stopper 5 time can unload in fertilising and just then load onto at seeding time and can sow.
