The cultivation part handling could be finished by hand, with no need of any tools. The utility model has the advantages of convenient cultivation part handling, time and trouble-saving and is a updated product with convenient cultivation part handling.

Description

The tiller workpiece that the farming part is easy to loading and unloading

Technical field

The utility model relates to a kind of workpiece of tillage machinery, the tiller workpiece that particularly a kind of farming part is easy to loading and unloading.

Background technology

Existing tiller workpiece, its farming part all is fixed on the turning cylinder, or directly is set on the turning cylinder, and promptly workpiece is an integral body; Be fastened on the turning cylinder, must utilize specific purpose tool to load and unload.When the farming part damages, the former, or can only discard the overall work parts, or cut the farming part that damages under the saw and weld new farming part again, cost is high; The latter must adopt specific purpose tool to load and unload, and loads and unloads hard to tackle, bothersome time-consuming.

Summary of the invention

At above problem, the purpose of this utility model provides convenient, the timesaving farming part tiller workpiece easy to loading and unloading of saving trouble of a kind of farming part loading and unloading.

The tiller workpiece that a kind of farming part is easy to loading and unloading, comprise turning cylinder and farming part, it is characterized in that: turning cylinder is provided with some extension knife plates, hang the bearing pin that the knife plate two ends are provided with two symmetries, farming part and wire loop are housed are being sleeved on two ends on the bearing pin and are separately positioned on torsion spring on turning cylinder and the farming part establishing on the bearing pin.

The utility model loading and unloading farming part need not any instrument, only can finish with hand; Loading and unloading farming part is convenient, and saving trouble saves time, and is that a kind of farming part loads and unloads very box lunch upgrading products easily.

Among the figure: back-up ring 1, big belt wheel 2, nut 3, farming part 4, turning cylinder 5, extension knife plate 6, bearing 7, bearing block 8, square key 9, workpiece driving shaft 10, alignment pin 11, bearing pin 12, torsion spring 13, blade bar shaped slotted hole 14, blade arc surface 15, blade torsion spring hole 16.

Embodiment

Describe in detail below in conjunction with drawings and Examples:

Farming part among figure tiller workpiece easy to loading and unloading mainly comprises turning cylinder 5, farming part 4, be welded on some helical forms on the turning cylinder 5 extension knife plate 6 spaced apart, be fixed on the bearing pin 12 hung on knife plate 6 two ends, establish the farming part 4 that is contained on the bearing pin 12 and be enclosed within on the bearing pin 12 and two ends are located at torsion spring 13 on turning cylinder 5 and the farming part 4 respectively.

Farming part 4 among Fig. 1 is the careless steel wire of rake.Its torsion spring 13 is set directly on the careless steel wire 4 of rake, and promptly farming part 4 is a single piece with torsion spring 13.During installation, as long as pull the careless steel wire of rake 4 two ends with hand the torsion spring wire loop change that is located on the careless steel wire 4 of rake greatly can be enclosed within the careless steel wire 4 of rake on the bearing pin 12 easily, the inner that will harrow careless steel wire 4 then is positioned on the turning cylinder 5 and gets final product; During dismounting,, just can take off harrowing careless steel wire 4 easily at the rake grass end of pulling the careless steel wire 4 of rake with hand as long as making the torsion spring wire loop that is located on the careless steel wire 4 of rake become big; So, need not any instrument during loading and unloading farming part 4, only can finish with hand, loading and unloading farming part 4 is convenient, and saving trouble saves time.When grass rake, along with the rotation of turning cylinder 5 with harrow the effect of careless resistance, be located on the careless steel wire 4 of rake the torsion spring wire loop tightly mounting board on bearing pin 12, harrow careless steel wire 4 difficult drop-offs.Harrow careless steel wire 4 during in order to ensure the rake grass and can not come off, the torsion spring 13 that is arranged on the careless steel wire 4 of rake among the figure is the turriform torsion spring, and the torsion spring wire loop that promptly is enclosed within on the bearing pin 12 is the torsion spring of turriform.The aperture of turriform torsion spring 13 wire loop small ends is less than the diameter of bearing pin 12.

Fig. 5 is a kind of workpiece that loosens the soil of the present utility model, and promptly farming part 4 is the blade that loosens the soil.Be welded with shape some extension knife plates 6 spaced apart in the shape of a spiral on the work turning cylinder 5; The length direction of hanging knife plate 6 is welded with the bearing pin 12 of two symmetries; The blade 4 that loosens the soil is established and is contained on the bearing pin 12; The wire loop of torsion spring 13 is sleeved on the bearing pin 12, and an end leans against on the turning cylinder 5, and the other end is hooked in the blade torsion spring hole 16.During installation, the wire loop of the blade bar shaped slotted hole 14 of blade 4 and torsion spring 13 is enclosed within on the bearing pin 12 as long as will loosen the soil, and the circular arc side that makes blade arc surface 15 abuts on the turning cylinder 5, makes the two ends of torsion spring 13 lean against turning cylinder 5 respectively and be hooked in the blade torsion spring hole 16 then and gets final product; During dismounting, 16 extract out and can take off the blade 4 that loosens the soil easily from blade torsion spring hole as long as will be hooked in the blade torsion spring hole 16 torsion spring 13 ends.So, need not any instrument during loading and unloading farming part 4, only can finish with hand, loading and unloading farming part 4 is convenient, and saving trouble saves time.When loosening the soil, torsion spring 13 can firmly be fixed on the blade 4 that loosens the soil on the turning cylinder 5 under the revolving force of turning cylinder 5 and the blade that loosens the soil loosen the soil the effect of resistance tightly, so the blade 4 that loosens the soil can not come off, and can not fly out.
