Description

Изобретение относитс к сельскохоз йственному машиностроению, в частности к почвообраЬат13ваю1дим оруди м дл фрезеровани почвы в приствольных полосах в садах, в междур дь х виноградников .The invention relates to agricultural machinery, in particular, to soil tillage tools for milling soil in pristine leaves in orchards, between vineyards.

Известно почвообрабатывающее орудие с вертикальным валом вращени , несущее вертикально установленные элементы в виде Г- образных ножей 11.A tillage implement with a vertical shaft of rotation is known that carries vertically mounted elements in the form of L-shaped knives 11.

Недостаток этого устройства - повреждение штамбов деревьев и их корневой системы режущими элементами.The disadvantage of this device is damage to the tree trunks and their root system by cutting elements.

Известно почвообрабатывающее орудие , включающее , привод и рабочий орган в виде вертикального вала, на котором установлен подпружиненный . диск с рыхл цими элементами 2 .A tillage implement is known, including a drive and a working body in the form of a vertical shaft on which a spring-loaded one is mounted. disk with loose elements 2.

Недостаток известного оруди частые поломки рабочего органа при встрече с пн ми, камн ми, корн ми деревьев.The disadvantage of the known tool is frequent breakdowns of the working organ when meeting with mon, stones, and roots of trees.

Цель изобретени - предотвращение поломок рабочего органа оруди при встрече с преп тствием.The purpose of the invention is to prevent damage to the tool body when it encounters an obstacle.

Дл достижени этой цели диск установлен на валу рабочего органа свободно и снабжен.зубчатым венцом,а на конце вала закреплена зубчата шайба , наход ща с в зацеплении с зубчатым венцом диска.To achieve this goal, the disk is mounted on the working tool shaft freely and provided with a gear ring, and a tooth washer is fixed at the end of the shaft and meshes with the disk ring gear.

На фиг. 1 показано почвообрабатывающее орудие, план; на фиГ. 2 - разрез А-А на фиг. 1.FIG. 1 shows a tillage implement, plan; on fig 2 shows section A-A in FIG. one.

Орудие состоит из 1, привода 2, включающего центральный конический редуктор 3, карданный вал 4, боковой конический редуктор 5 цепной контрпривод 6 и цепную выдвижную секцию 7, от которой крут щий момент подводитс к рабочему органу 8. Рама 1 оруди и выдвижна секци 7 св заны между собой с помощью гидроцилиндра 9, управл емого посредством гидросистемы с сигнальным щупом 10, paicnoложенным на вьщвижной секции 7. Рабочий орган 8 включает вал 11, диск 12, The tool consists of 1, a drive 2 comprising a central bevel gear 3, a propeller shaft 4, a side bevel gear 5, a chain counter gear 6, and a chain pull-out section 7, from which the torque is supplied to the working member 8. The frame 1 of the gun and pull-out section 7 st interconnected by means of a hydraulic cylinder 9, controlled by a hydraulic system with a signal probe 10, paicno laid on the sliding section 7. The working body 8 includes a shaft 11, a disk 12,

20 на нижнем торце которого имеетс зубчатый венец 13, рыхл щие элементы 14. Диск 12 установлен на вал 11 свободно и удерживаетс с помощью пружины 15 и зубчатой шайбы 16, причем последн жестко закреплена на валу 11. Пружина 15 в верхенй части упираетс в шайбу 17 и гайку 18. На валу нарезана резьба дл гайки 18, регулирующей усилие пружины 15.20 at the lower end of which there is a gear ring 13, loosening elements 14. The disk 12 is mounted on the shaft 11 freely and held by means of a spring 15 and a gear washer 16, the latter being rigidly fixed on the shaft 11. The spring 15 in the upper part abuts the washer 17 and a nut 18. On the shaft there is a thread for the nut 18, which regulates the force of the spring 15.

Claims

The tool works as follows. From the BOM of the tractor, the torque is transmitted through the drive shaft 4, bevel gears 3 and 5, the chain pin drive 6 and section 7 to the shaft 11 of the working element 8. With the start of the rotation of the disk 12 loosening Elements J.4 come down to the soil surface. and are deepened by their own gun. Since the disc 12 with the loosening elements 14 is mounted on the shaft 11 freely and is rotated by a spring 15, which holds the gear ring 13 of the disk 12 and the gear washer 16, the disk 12 brakes when it encounters an obstacle of the loosening elements 14 and its ring gear 13 is released from the engagement with the gear washer 16, then the disk 12 is moved up the shaft 11 before the obstacle is bypassed. After the obstacle has been bypassed, the spring 15 opens and returns the disk 12 until its gear rim 13 is secured with a gear washer 16. The soil is treated without damage to the root system of the plantations, the large roots, and other obstacles without breakdowns. If necessary, the force of the spring 15 is controlled by the nut 18. This makes it possible to tillage in rows between bushes or trees without damaging the plantations and without hauling the tool. The invention The soil-cultivating tool, including the frame, the drive and the working body in the form of a vertical shaft, on which a spring-loaded disk with loosening elements is mounted, is characterized in the organ is free and provided with a gear crown, and a gear washer is fixed at the end of the shaft and meshes with the gear crown of the disk.
