Description
Technical field
The utility model relates to a kind of novel rake group of scarification equipment, and particularly a kind of heavy scarification equipment rake group of be content with very little tandem product designing requirement, maintenance convenient belongs to agricultural machinery technological field.
Background technology
It is one of of paramount importance cargo handling operation in the agricultural production wholely.Disc have good loosen the soil, hack and stubble-cleaning function, not only often use ploughing whole ground, back, can also be used to carrying out shallow winter breaking, with rake do farmwork for a soldier's family operation, extensive use on scarification equipments such as combined soil preparing machine, compound cultivator, disk harrow at present.The rake group is as the important workpiece of scarification equipment, and resistance suffered during work is bigger, and its structural design all has material impact for the convenience of transaction capabilities, reliability and the maintenance of whole facility.At present, the bearing inner ring of China's universal architecture rake group is a square hole, generally comes the location bearing support arm with the hole on the rake group beam, and an end of square shaft is forged into hemispherical usually and positions.The shortcoming that this method is brought has: there are certain clearance diametrically in square shaft and brearing bore; Bearing bears the axial force that adds in advance because of the mismachining tolerance accumulation possibly; Stressing conditions can obviously worsen, and service life is shorter, and the processing technology of part is complicated; The accuracy of manufacture is had relatively high expectations, be unfavorable for reducing production costs and improving functional reliability.
Summary of the invention
The purpose of the utility model is the weak point that overcomes prior art, proposes a kind of installation, maintenance, adjustment is easy, and highly versatile uses disk harrow group more reliably.
To achieve these goals, the technical scheme that the utility model adopted is: a kind of novel rake group of scarification equipment, mainly form by blade, bearing support arm, bearing block assembly, square shaft, a pipe, scraping device, rake group crossbeam, pressing plate and locking nut etc.Blade is through on the square shaft and manages between utilizing and separates, and the bearing block assembly is linked to each other with the bearing support arm by two bolts, and the bearing support arm is installed on the rake group crossbeam through pressing plate and four bolts.
Above-mentioned rake group, for the ease of safeguarding that it is spacing that the square shaft two ends all adopt locking nut to carry out, part dismounting, maintenance and maintenance on the rake group are all very convenient, and have saved the processing technology of forging hemispherical positioning end, have reduced processing cost.
Above-mentioned rake group, for the tandem product designing requirement that is content with very little, said rake group crossbeam is made up of two to three square tubes, when blade quantity for using two square tubes more after a little while, when blade quantity more for a long time, with three square tubes.Be welded with convexity on the rake group crossbeam, with the axial location of restriction bearing support arm.
Above-mentioned rake group, in order to improve the force-bearing situation of bearing, said bearing block assembly is made up of square shaft sleeve, end cap, bearing block, bearing and oil sealing, and the endoporus of square shaft sleeve is square, is enclosed within on the square shaft, and the bearing of employing is a pair of common taper roll bearing.
Above-mentioned rake group; For the scraping effect of improving the scraping device and the moulding process that reduces clean-up scraper; Said scraping device is made up of clean-up scraper, clean-up scraper crossbeam and spacing pressing plate; The clean-up scraper crossbeam is two band steels, and the groove of clean-up scraper and spacing pressing plate is stuck in the below and the top of clean-up scraper crossbeam, connects with bolt between the three.Unclamp bolt, the axial location of single clean-up scraper can conveniently be regulated, with and blade between reach suitable scraping gap.
Above-mentioned rake group, the blade quantity of installation are generally 7 to 11.
Compared with prior art, the utility model has the advantages that: rake group bearing block has been installed a pair of common taper roll bearing, can improve the stressing conditions of bearing, improves the service life of bearing; Axial distance between clean-up scraper and the blade can conveniently be adjusted, and has reduced the moulding process of clean-up scraper; Rake group crossbeam can use 2 or 3 square tubes to form, on the square shaft part can install from the square shaft two ends, dismounting, the versatility of each parts is very high, is easy to reduce production costs, and safeguards simple and conveniently, can satisfy the designing requirement of tandem product.

Embodiment
Embodiment below in conjunction with description of drawings the utility model:
Like Fig. 1, shown in 2, the novel rake group of the utility model mainly is made up of blade (1), bearing support arm (2), bearing block assembly (3), square shaft (4), pipe (5), scraping device (6), rake group crossbeam (7), pressing plate (8) and locking nut (9) etc.Bearing block assembly (3) links to each other with bearing support arm (2) through two bolts; Bearing support arm (2) is installed in rake group crossbeam (7) below through pressing plate (8) and four bolts; Scraping device (6) is installed in the rear of rake group crossbeam (7), and locking nut (9) fixed limit is all adopted at square shaft (4) two ends.Rake group crossbeam (7) is formed by being stuck in four bolts two or three square tubes, and being connected between bearing support arm (2) and the rake group crossbeam (7) is not to position with the hole, so the axial location of same rake group upper bearing (metal) support arm (2) can be adjusted arbitrarily.When work, the rake group is carried out operation with certain drift angle, and bearing support arm (2) can receive an axial force, goes up solder-bump at rake group crossbeam (7) for this reason and limits endwisely slipping of bearing support arm (2).
As shown in Figure 3, bearing block assembly (3) mainly comprises square shaft sleeve (3-1), end cap (3-2), bearing block (3-3), bearing (3-4) and oil sealing (3-5).Bearing block assembly (3) comprises a pair of taper roll bearing (3-4).Square shaft (4) is enclosed within the square shaft axle sleeve (3-1), and a pair of common taper roll bearing (3-4) has been installed on the square shaft axle sleeve (3-1), and two ends are fixed with end cap (3-2), and (3-5) seals with oil sealing.The good airproof performance of bearing block assembly (3) can guarantee bearing (3-4) good working environment, reliable operation under abominable condition of work.
As shown in Figure 4; Scraping device (6) mainly comprises clean-up scraper (6-1), clean-up scraper crossbeam (6-2) and spacing pressing plate (6-3); The groove of clean-up scraper (6-1) and spacing pressing plate (6-3) is stuck in the below and the top of clean-up scraper crossbeam (6-2), connects with bolt between the three.Clean-up scraper crossbeam (6-2) is two band steels, unclamps under the situation of bolt, and the axial location of clean-up scraper (6-1) can conveniently be regulated, with and blade between reach suitable scraping gap, strengthen the scraping effect.
The rake group of the utility model, its blade (1) quantity can conveniently increase, and generally can install 7 to 11, to adapt to the needs of different operating fabric width.As shown in Figure 5, when the quantity of blade (1) was 7, rake group crossbeam (7) had adopted two square tubes, and a slice blade (1) has been arranged in the outer end of bearing support arm (2).As shown in Figure 6, when the quantity of blade (1) was 11, rake group crossbeam (7) had adopted three square tubes, and two blades (1) have been arranged in the outer end of bearing support arm (2).
When the rake group is installed the blade (1) of varying number; Only need that the length of corresponding change rake group crossbeam (7) and clean-up scraper crossbeam (6-2) gets final product when blanking, other parts all can be general, so versatility is very strong; Be easy to reduce production costs, meet the seriation designing requirement of Related product.
