Detailed Description

It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the disclosure. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application. As used herein, the singular forms "a", "an", and/or "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof;

for convenience of description, the words "upper", "lower", "left" and "right" in the present application, if any, merely indicate correspondence with the upper, lower, left and right directions of the drawings themselves, and do not limit the structure, but merely facilitate the description of the present invention and simplify the description, rather than indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

The terms "mounted", "connected" and "fixed" in the present invention should be understood in a broad sense, for example, they may be fixedly connected, detachably connected, or integrated; the two components can be connected mechanically or electrically, directly or indirectly through an intermediate medium, or connected internally or in an interaction relationship, and specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

As introduced in the background art, the film picking part of the elastic tooth chain harrow type residual film recycling machine in the prior art is an elastic tooth, the elastic tooth is sleeved on a fixed pipe and fixed by a bolt, and the fixed pipe and a chain plate are fixed by the bolt. When the membrane was chosen to bullet tooth burial, can receive the huge impact force of ground for bullet tooth, this impact force transmits the link joint department of bipitch conveyor chain through the fixed pipe of bullet tooth, causes tearing of link joint, leads to the fixed pipe of bullet tooth to drop, makes the complete machine break down, in order to solve above technical problem, this application has provided a mounting device and bullet tooth chain harrow formula plastic film residue collector of the fixed pipe of bullet tooth.

In a typical embodiment of the present application, as shown in fig. 4, 5, and 6, the elastic tooth fixing tube mounting device includes an elastic tooth fixing tube 4 and a link plate 3, both ends of the elastic tooth fixing tube 4 are fixed on the link plate 3, and the elastic tooth fixing tube 4 is in surface-to-surface contact with the link plate 3.

Furthermore, the upper surface and the lower surface of the two ends of the elastic tooth fixing tube 4 are horizontal surfaces, and the lower surface is a surface contacted with the chain plate.

The installation device of the elastic tooth fixing pipe in the embodiment is mainly installed on the elastic tooth chain harrow type plastic film residue recycling machine, and the elastic tooth chain harrow type plastic film residue recycling machine mainly comprises a depth limiting device, a stubble collecting device, a rotary tillage device, a traveling wheel, an elastic tooth chain harrow type plastic film residue picking and conveying device, a film collecting box and the like. When the machine works, the machine is driven by a rear power output shaft of a tractor, a film lifting shovel lifts residual films from soil, a film picking elastic tooth lifts the residual films, an elastic tooth chain harrow rotates clockwise, the lifted residual films are conveyed upwards along a film conveying supporting plate, and the residual films fall into a film collecting box when being conveyed to the rear of the machine;

the working process of the elastic tooth chain harrow type residual film recycling machine comprises three stages of elastic tooth soil-entering and film-picking, residual film lifting upwards along with the elastic tooth and residual film falling into a film collecting box.

The prior art elastic tooth 1 is mounted on an elastic tooth fixing pipe 2 as shown in fig. 1, and the elastic tooth fixing pipe 2 is connected with a chain plate 3 on a double-pitch conveying chain through a bolt as shown in fig. 2 and 3. When the elastic teeth 1 penetrate into the soil and pick up the film, the elastic teeth are subjected to huge impact force given to the elastic teeth by the ground, and the impact force is transmitted to the chain plate of the double-pitch conveying chain through the elastic tooth fixing pipe to tear the chain plate, so that the elastic tooth fixing pipe falls off, and the whole machine breaks down; the applicant takes a lot of improvement schemes into consideration after a long time of experiments, the effect is not good, and after long time of stress analysis, the impact force is mainly transmitted to the chain plate of the double-pitch conveying chain through the elastic tooth fixing pipe, so that the chain plate is torn, the elastic tooth fixing pipe falls off, and the whole machine breaks down.

In view of the above problem, the applicant of the utility model discloses a new spring tooth fixing pipe, which is flattened at both ends, as shown in fig. 3, so that the tangent contact between the spring tooth fixing pipe and the chain plate is changed into surface-to-surface contact, as shown in fig. 1, thereby increasing the contact area.

According to P ═ F/S
