Description

A kind of used with tractor power main transmission box

Technical field

This utility model belongs to technical field of agricultural machinery, is specifically related to a kind of used with tractor power main transmission box.

Background technology

It is known that China is a large agricultural country, at seeding time, its function of the agricultural machinery and implement of needs is more single for crops One, need first to carry out the loose and smooth of soil with rotary cultivator, overlap machinery with two the most again or with a set of, there is fertilising and sowing The machinery of function applies fertilizer respectively and sows.Carrying out sowing with these machineries, to act on not only power consumption many, and working performance is low Under, labor intensity is bigger, and ferti-seeding quality can not be guaranteed.In order to improve this situation, now on rotary cultivator Fertilizing and seeding apparatus is installed, and is connected with the pack roller after rotary cultivator by driving chain, said structure easily occurs sowing What the situation uneven with fertilising was serious wastes seed and chemical fertilizer, traces it to its cause, is primarily present following point: 1, when field is wetter Time pack roller on there will be the situation of foundry loam soil, now sow and apply fertilizer and there will be the situation of instability, local big at some Amount sowing and fertilising, do not sow in other places and lower fertilizer；Need when solving drawbacks described above to use manually to carry out scraping roller；2、 When the situation that straw foreign material are too much and ground is wet occurs, easily cause straw foreign material and the poly-heap of earth ultimately causes pack roller not Turning, thus cause the phenomenon stopping sowing, now such soil is then not suitable for using the said equipment to carry out rotary tillage, sow and execute Fertile；3, when there is rotary tillage excessive velocities, easily there is skidding in pack roller, now will necessarily cause and sow and lower fertile pause Situation；4, the said equipment cannot work at the edge in soil and limes marginis due to pack roller, and therefore place cannot be carried out sowing And fertilising, cause the waste of land resource.

Utility model content

The purpose of this utility model is to overcome defect of the prior art, and provides one exclusively for seeding apparatus and to execute Fertile device provides power, has simple in construction, reasonable in design, easy to use, it is possible to realize no matter which kind of equal energy of model tractor Use, and walking and seeding and fertilizing work can be made to carry out a kind of used with tractor power main transmission box being switched fast.

The purpose of this utility model is achieved like this: include that casing, the side of described box house are provided with and are sleeved on Link stopper, spring, Drive ratchet and the outer surface active umbrella with hook tooth fixed by the first spring in tractor motive power output shaft Gear；Driving bevel gear is meshed with driven bevel pinion, and driven bevel pinion is sleeved on the outside of power transmission shaft, the one of driven bevel pinion Side is provided with and is sleeved on the second spring of power transmission shaft end and fixes link stopper, driven bevel pinion and the second spring and fix and be provided with between link stopper Back-moving spring, the opposite side of driven bevel pinion is provided with movable set separation set on power transmission shaft, the described both sides separating set Offering shift fork mounting groove respectively, be provided with the prong of shift fork in shift fork mounting groove, the middle part of shift fork is provided with shift fork hole, shift fork Top is provided with shift fork arm mounting groove, is provided with the shift fork axle being connected with casing, described shift fork arm mounting groove in described shift fork hole Inside being movably installed with shift fork arm, the top of shift fork arm is connected with casing by bolt, is provided with and dials gear hole in the middle part of shift fork arm, described group The inside in gear hole is coated with fork shift bar, and the position that described casing is corresponding with fork shift bar offers lever hole；Described transmission spine Being provided with wedge between wheel and power main transmission box driving bevel gear, the top of described wedge is provided with power cut bar, described Power cut bar is arranged in the driver's cabin of tractor.

Preferably, the opposite side of described box house is provided with the standby driving bevel gear being meshed with driven bevel pinion, standby It is coated with standby power transmission shaft with driving bevel gear activity, described standby power transmission shaft is sequentially installed with standby Drive ratchet, bullet Link stopper fixed by spring and spare spring；The outer surface of standby driving bevel gear is provided with the hook tooth suitable with standby Drive ratchet； One end of standby power transmission shaft, standby Drive ratchet, spring and spare spring are fixed link stopper and are separately positioned on the inside of casing；Described The standby wedge with standby power cut bar it is provided with between standby driving bevel gear and standby Drive ratchet.

Preferably, described driven bevel pinion internal sleeve is gear shaft equipped with tooth set, power transmission shaft, the gear on gear shaft with Tooth set is meshed.

Preferably, the bottom of described shift fork arm is J-type, and its underpart is flexibly connected with shift fork arm mounting groove.

Preferably, described fork shift bar is connected with the bottom of separating arm with tractor hydraulic lifting arm by connecting rod.

A kind of used with tractor power main transmission box made according to such scheme, permissible by arranging this power main transmission box Make it be connected with the seeding apparatus in rotary tillage planting and fertilizing machine and fertilizer apparatus, and directly drive seeding apparatus and fertilizer apparatus work Make, it is to avoid because pack roller cannot work the defect that causes seeding apparatus and fertilizer apparatus to work；By arrange fork shift bar, Connecting rod, separating arm and tractor hydraulic lifting arm are being capable of power source and seeding apparatus and fertilizer apparatus power fast clutch While be capable of tractor seeding apparatus and fertilizer apparatus at a high speed walking when and do not work, in order to avoid said apparatus Occurring extremely cannot using, this utility model is provided with Drive ratchet, driving bevel gear and wedge the most especially, is guaranteeing Realize outside above-mentioned same function, power source also can be made more efficient and convenient with the connection of this power main transmission box；This practicality is new The setting of the internal driving bevel gear arranged of type and standby driving bevel gear can facilitate tractor motive power output shaft Fast Installation While ensure that it also to be able to arbitrarily to be arranged on the left and right sides at tractor rear portion；There is simple in construction, reasonable in design, use Convenient, it is possible to realize no matter which kind of model tractor all can use, and walking and seeding and fertilizing work can be made quickly to cut The advantage changed.
