Abstract

Disclosed is a hydraulic rise-and-fall trailing planter which comprises a traction frame, a planter frame, a ground wheel drive clutch device, a seed manure box, ground wheels, a seeding fertilizing device and an intermediate drive mechanism. The ground wheels are in drive connection with the seed manure box and a precise planter through the ground wheel drive clutch device and the intermediate drive mechanism; a hydraulic synchronous shaft rotary arm rise-and-fall mechanism arranged between a ground wheel rotary arm and the planter frame is capable of separating the planter frame and each part connected with the planter frame from ground to a certain height, and a linkage mechanism is arranged between the ground wheel drive clutch device and the ground wheel rotary arm. The hydraulic rise-and-fall trailing planter has the advantages that the hydraulic synchronous shaft rotary arm rise-and-fall mechanism is adopted to tow the planter, accordingly a tractor driver can operate at an original position; secondly, work breadth is increased from two ridges to four ridges; thirdly, the groove-type seed manure box meets modern agriculture planting requirements of deep fertilization and grain fertilizer fertilization so as to provide good basic conditions for stable and high yields of crops; fourthly, because of widened seeding width and increased seeding speed, work cost can be reduced, and work efficiency is improved by 50%.

Description

The hydraulic pressure trail-behind planter that rises and falls

Technical field

The utility model relates to the trail-behind planter that a kind of sower, especially hydraulic control of ridge farming thing are risen and fallen.

Background technology

This type of sower is disclosed by following document in the prior art: " operation instructions " of the product B F--2 type soybean precision sower of the Heilongjiang Province factory that publishes in January, 1993 have disclosed this machine mating power is 12 to 20 horsepowers of wheel tractors, connect for bearing to hang, because the restriction of bearing suspended weights, sower that can only supporting two ridges, the narrow production efficiency of sown scope is low.

State Patent Office disclosed a kind of trail-behind planter (notification number CN2561195) on July 23rd, 2003, the rack construction of this machine is before frame, the rear cross beam end positions is respectively by connect into a sealing quadrilateral frame along beam, install and fix supporting land wheel running gear in two outsides along beam, its front beam is equipped with the imitative type ferti-seeding parts of four connecting rods, do field when transportation non-, with controlling rising and falling of the imitative type ferti-seeding workpiece of four connecting rods along the camber tooth plate take-off and landing device that is provided with on the beam, this implement structure is narrow, the gap is little, the more shallow requirement that can not satisfy the deep placement fertilizer on the agronomy of fertilising shovel fertilization depth, and this take-off and landing device manual operation.

In addition, at present use in the rural area drags for a short time certainly that major part is 18 to 24 horsepowers of power, and the supporting sower sown scope of this type is two ridges, high-power obviously occurred and has drawn dolly, and it is many to consume fuel cost, the production cost height; Because the sower of prior art can only be broadcast two ridge operations, and tractor is repeated into, the pressure of bringing thus often, the soil property laxity is damaged, accumulate natural precipitation for taking precautions against drought and crop growth is affected.

Summary of the invention

The purpose of this utility model be to provide a kind of can with the supporting hydraulic pressure of the wheel tractor of the various middle-size and small-size specifications and models tractor seeder that rises and falls, fertilising shovel fertilization depth is more shallow to hold together the requirements that number can not satisfy the sowing deep placement fertilizer on the agronomy less to solve, and this take-off and landing device manual operation, and high-power draws the problem of dolly.

The technical solution of the utility model is: comprise hitch frame, frame, the land wheel transmission clutch, the seed manure case, land wheel, seeding and fertilizing device and intermediate transmission mechanism, hitch frame is connected the front end of frame, land wheel is rotatably connected on the rear end of a land wheel pivoted arm, the front end of this land wheel pivoted arm is installed on the main shaft of frame front rotationally, seed manure case and seeding and fertilizing device be installed in respectively the top of frame and below, below the seeding and fertilizing device precise seeder is housed, it is characterized in that: described land wheel is in transmission connection by land wheel transmission clutch and intermediate transmission mechanism and described seed manure case and precise seeder; The hydraulic pressure synchronizing shaft pivoted arm lift that can make frame and connected each parts built on stilts certain altitude is housed between described land wheel pivoted arm and frame, between described land wheel transmission clutch and land wheel pivoted arm, link gear is housed.

The utility model hangs sower and compares and have following advantage with existing bearing:

Hydraulic pressure rises and falls trail-behind planter because sower is provided with the operation of tripod mode of traction, and when dog leg occurring in the tractor operation, tangible dog leg can not appear in sower yet to be changed, and can improve the making ridge operation quality; This machine adopts hydraulic pressure synchronizing shaft pivoted arm lift tractor seeder, and the small tractor driver just can operate in position; Its two working width can increase to four ridges by two ridges, makes 18 to 24 horsepowers of effective and reasonable couplings of the supporting power that drags for a short time; Three slot type seed manure casees solve deep application of fertilizer fertilizer and execute a mouthful fertile modern agronomy planting requirement, for the crop high and stable yields provide the good basis condition; Can reduce operating cost because sown scope is widened the raising of speed of drilling, improve operating efficiency 50%.
