Abstract

The utility model discloses a semi-automatic seed dibbler, belonging to an agricultural machine. The semi-automatic seed dibbler comprises a handle, a pillar, a seed box, a seed guide pipe, a seed feeding pipe, a seed valve, a foot shovel, etc. When any one of the control handle and the seed valve is opened, the other is automatically closed via a rotary lever so as to realize quantitive seeding. With the advantages of labor saving, high speed and high efficiency, the utility model can be operated by one person and is particularly applied to interplant.

Description

Semi-automatic seed dibbler

The utility model relates to a kind of semi-automatic seed dibbling machine, belongs to farm machinery.

Popularization along with the scientific farming technology, in recent years, bunch planting crops such as interplanting corn, beans, peanut have become basically universal in China North China and have commonly cheated seed addition again with planes such as spades, hoes before the wheat harvest, blinding or with very easy dibbler then, all be out a cave, add seed one time, it is big and speed is slow to operate labour intensity like this.The Decree of Patent Office of China number of patent application be two kinds of dibblers of CN87206499U and application number 88221284.2, their weak point is to regulate the amount of sowing according to kind of subcategory and seed variety; Application number is that CN87206499U dibbler structure is complicated simultaneously, and application number is that 88221284.2 dibbler seed tubes are easily stopped up by earth.It is simple in structure that the utility model provides, and can control a kind of semi-automatic seed dibbling machine of the amount efficiency of sowing.

The technical solution of the utility model realizes by following content: it is by handle 1, pillar 8, pin shovel 22, seed-box 14, seed tube 15, grain tube 20, retainer ring 21 compositions such as grade, below handle 1 by the U-shaped circle of adorning two symmetries, in the U-shaped circle, place flexible handle 3, being communicated with seed tube 15 below the seed-box 14 is inclined tubes, promptly be about 45 ° with seed-box 14 or with the vertical center line of pillar 8, grain tube 20 below it is parallel contacts with pillar 8, the two tightens up to make it with retainer ring 21, seed-box 14 is connected and fixed by fixed mount 5 and pillar 8, on fixed mount 5, be provided with rotating lever 12 mechanisms, be provided with two valves 17 at seed tube 15,18, the small valve plug that valve is 17 li, connect iron wire 6, pass the aperture of the support 10 on the pillar 8, center by the spring 9 above the support 10, link to each other with an end of top rotating lever 12, connecting iron wire 7 on the small valve plug that valve is 18 li passes spring 11 below the support 10 and the aperture above the support 10 and the aperture of support 5 and is fixed on the joystick 3, be suggested valve 18 when carrying joystick 3 valve plugs, because joystick 3 is by the other end of 4 times companies of iron wire rotating lever 12, make the small valve plug of 17 li on valve enter 17 li on valve, realize closing.Also be provided with a control valve 19 between two valves 17,18 of seed tube 15, rotary screw can be regulated the size of control chamber, to reach suitable deposit grain weight.Seed borrows self gravitation to enter seed tube 15 by seed-box 14, control through valve, promptly when a valve opening, another valve closing of while, when valve 17 was closed, valve 18 was opened seeds and is entered grain tube 20, has pin shovel 22 in the lower end of pillar, can be used for excavating soil pit, seed falls in the soil pit from the grain tube end opening, finishes program request.

The utility model compared with prior art has simple in structurely, is easy to make, and cost is low, use wheel just be suitable for a people behaviour do, laborsaving, and speed of drilling is fast, realizes quantitatively sowing, the efficient height is specially adapted to interplanting.

Fig. 1 is the utility model structural representation.

Fig. 2 is that the A of Fig. 1 handle portion is to view.

Fig. 3 is that Fig. 1 pin shovel B partly is to view.

1. handle, 2.U type circle, 3. joystick, 4. iron wire, 5. fixed mount, 6. iron wire, 7. iron wire, 8. pillar, 9. spring, 10. support, 11. springs, 12. rotating levers, 13. the seed case lid, 14. seed-boxes, 15. seed tubes, 16. control chambers, 17. valve, 18. valves, 19. control valves, 20. grain tubes, 21. retainer ring, 22. pin shovel, 23. pedals.

Below with reference to the specific descriptions of accompanying drawing work with embodiment.

Be the cuboid seed lid 13 that is provided with suitable for reading by above-mentioned accompanying drawing seed-box, the bottom links to each other with seed tube 15 and partly is down cubic tapered, by fixed mount 5 seed-box 14 is fixed on the support 8.The axis of the axis of seed tube 15 and pillar 8, be the angle about 45 °, its cross section is rectangle, the lower end links to each other with grain tube 20, grain tube 20 is fixed on the pillar 8 by at least two above retainer rings 21, grain tube 20 can be used plastic tube, and pillar can adopt wooden structures, to reduce cost and weight reduction.Being provided with pedal 23 above the pin of the bottom shovel 22 can be for the pin cave of firmly cutting the earth.

Point sowing time, with the pedal (23) of foot-operated pin shovel 22, the shovel face slightly-inclined of pin shovel enters in the soil, then, sets upright dibbler, goes up anti-joystick 3, and valve 18 is opened, and valve 17 is closed simultaneously, and at this moment, the seed in the control chamber 16 falls into soil pit by grain tube 20.Loosen joystick 3, valve 18 is replied and driven to spring 11 by compression and spring 9 closes it, drives valve 17 it is opened, and seed is full of control chamber 16 again, has so just finished a program request.
