Description

“CONSTRUCTIVE ARRANGEMENT IN ROLL KNIFE RELIEF COPIER”

Subject matter:

[001] The present Utility Model Patent refers to a new constructive provision introduced in a knife roller used in agriculture to prepare the land for planting. As an improvement, the object presents a better copy of the soil relief obtained by its construction, where the rollers act independently of the chassis, tightening from sets of cylinders, pulleys and the equipment wheels.

State of the Art:

[002] Knife roller devices have long been used in agriculture, with the objective of preparing the planting in order to crush the remains of the previous crop without burying them in the soil, making the land have uniform coverage and ensuring the correct handling of humidity and invader control conditions. The passage of the knife roll forms a uniform bed that improves the performance of seeders and the quality of the crop as a whole.

[003] The document is known to the state of the art

MU9003046-0, by Eliseu José Schaedler, deposited on 08/02/2010, with the title “Arrangement in a Rolling Knife

Relief Copier ”that describes a device equipped with a rear roller (10) and two side rollers (11) supported by movable supports (4) attached by a joint (5) free to rotate. Springs (7) are associated with the mobile support (4) and restrict and correct this free rotation. The side rollers (11) are connected to the chassis (1) by articulation (14) associated with tie rods (15) and (16), provided with auxiliary ramps (18).

[004] As a problem in this previous model, the fact that the device contains the integrated chassis and

Petition 870180053981, of 06/22/2018, p. 31/36 / 6 supported by the rollers, that is, it has the weight of the chassis as an acting force on all the rollers during the work, which means that, during the rolling work, the existing crop remains are mostly cut and deposited in the soil, not just crushed. Cutting the remnants of the previous crop interferes with the humidity conditions and other control items of the new crop, as a layer of soil protection is not formed, which would be obtained by kneading, and exposes the roots of the crop prior to drying and new sprouting.

[005] In addition, as the joints allow only horizontal rotary movement, due to the rollers being integrated into the chassis, the asymmetric differences in the ground are not absorbed, that is, the copying is impaired because the terrain relief is not followed, resulting in irregularities.

Inventive Concept:

[006] The present Constructive Arrangement in Relief Copier Roll proposes practical improvements, as it is based on the concept of functional and manufacturing improvement in relation to the state of the art of the object.

[007] The terrain copier roller presents a constructive change in its main structure, which now contains a chassis fully supported on the wheelset in order to use only the weight of the rollers for kneading the culture previously existing in the area, without cutting -there. With this, the rollers are free to carry out better monitoring of the soil, and the straw that forms after rolling, as it is entirely kneaded, retains more moisture and provides faster decomposition of organic matter, favoring the new crop.

Petition 870180053981, of 06/22/2018, p. 32/36 / 6 [008] In addition, the rear side rollers now contain joints composed of two side pulleys together with cylinders with free oil passage, for the work mode and with blocked oil passage by activating the pressure hose or return - to the mode of transport. The cylinders can be driven mechanically, using a valve, or electrically, by means of a hydraulic block, to release or block the passage of oil through the cylinder. With the passage of free oil through the cylinder, it is possible to leave the rollers totally free for the work, collecting and opening the cylinder automatically, according to the applied soil. The front roller started to contain articulated side arms for up and down movement, making it also work independently of the chassis.

[009] For operation in transport mode, the two rear rollers are folded upwards, assuming the bilateral vertical position, and the rest of the device is suspended by the wheelset.

[010] Thus, the invention contemplates a device with chassis entirely designed in order to provide the movement of the knife rollers independently, resulting in a better final result in the copying of the soil.

Application field:

[01 1] The application of this Constructive Arrangement in Roll Relief Copying Knife occurs in the use of this as an agricultural implement.

Benefits:

[012] Constructive Arrangement in Roll Relief Copier Knife has the following advantages:

• Better quality in copying the soil obtained by the fact that the knife rollers move independently from the chassis, which is supported on the wheels;

Petition 870180053981, of 06/22/2018, p. 33/36 / 6 • As a result, the remains of the previous existing culture are kneaded, providing greater moisture retention and management of decomposition of organic matter, which benefits the new culture;

• The capacity of the tractor used to tow the machine is lower, compared to other models of knife rollers that need to drag the entire weight of the machine, because they have the weight of the entire chassis on the rollers, and consequently of the entire machine on the ground, as they have no wheels to relieve the weight of the chassis in the work mode;

• Less impact of the rollers with the ground, as each roll works independently, together with the remaining weight of the machine supported on the wheels. Thus, the soil does not suffer the impact of the entire machine chassis, also avoiding soil compaction, due to the machine having a high weight to be able to knead the crop.

Description:

[014] This Constructive Rolling Knife Arrangement

Relief Copier is composed of the chassis (1) equipped with the main structure (2) from where the lateral extensions (3) that support the side knife rollers (4) through the C support (5) decorate.

[015] The double wheels (6) are fixed by a tubular structure (7) fixed inferiorly to the main structure (2) of the chassis (1).

[01 6] The C support (5) that secures the side knife rollers (4) is fixed to the lateral extensions (3) through two pairs of C support (8) that, when joined, confine the pulleys (9 ) fixed by the sets of through pins and washers (10), forming independent joints. The clearance inside the C-bracket joint (8) allows horizontal movement independently of each side knife roller (4).

[1 7] The cylinder (1 1), of the type with free oil passage, is fixed to the lateral extension (3) and to the C support (5) by means of its own pins and, in addition to supporting the assembly in a way allowing the free articulation of the knife rollers (4), it is used to suspend them to the vertical position, suitable for displacement.

[01 8] The fact that the cylinders (1 1) are free of oil allows the oil to circulate in order to open or retract the cylinder automatically, according to the articulated movement necessary for the copying of the soil. The actuation of the cylinder (11) can be mechanical, by means of a valve, or electrically by means of a hydraulic block.

Petition 870180053981, of 06/22/2018, p. 35/36 / 6 [019] The front knife roller (12) contains articulated side arms (13) fixed to the chassis (1) through the pins (14), providing its movement up and down independently of the chassis.

Conclusion:

[020] In this way, the Constructive Arrangement in Relief Copier Roll is subsidized by unprecedented technical and functional characteristics, therefore deserving the legal protection sought.
