A árvore Pinus se cultivada de maneira correta, possibilita a extração de resina a partir de seu oitavo ano de vida e pode continuar produzindo resina por mais diversos anos. Esta resina é comumente utilizada para produção de terebentina e breu, elementos utilizados para fabricação de cosméticos, pneus, tinta, goma de mascar e entre outros produtos. [002] Manual tools are known for carrying out the striation activity in the Pine resin process, using cutting blades, operators make cuts with an ideal specific depth, to enable the extraction of resin from the Pine without harming its life cycle. . The Pinus tree, if cultivated correctly, allows the extraction of resin from its eighth year of life and can continue producing resin for several more years. This resin is commonly used to produce turpentine and rosin, elements used in the manufacture of cosmetics, tires, paint, chewing gum and other products.
[003] Entre os inconvenientes dos resinadores manuais do estado da técnica, está o tempo necessário para a realização dos cortes e a necessidade de habilidade e aplicação de força por parte do operador que executa a operação. Uma solução conhecida para solucionar tais inconvenientes é a utilização de resinadores mecânicos com motor elétrico, onde através de seus motores é possível movimentar uma lâmina de corte para ser realizada a estriagem na árvore. Porém, ainda assim, os dispositivos apresentam inconveniente de pouca mobilidade, peso elevado e cortes não muito eficientes. [003] Among the drawbacks of prior art manual resiners is the time required to make the cuts and the need for skill and application of force on the part of the operator performing the operation. A known solution to solve such inconveniences is the use of mechanical resin machines with an electric motor, where through their motors it is possible to move a cutting blade to perform the striation on the tree. However, the devices still have disadvantages of little mobility, high weight and not very efficient cuts.

É encaixada a parte interna (52) da capa (5) na máquina (M) através de uma abraçadeira (6) que envolve a aba (525) juntamente ao anel (A) da máquina (M), proporcionando estabilidade. O conjunto do dispositivo de corte é acoplado ao eixo (E) da máquina (M) através da fixação de seu eixo (E) no orifício (12). Em seguida, a parte externa (51 ) da capa (5) é encaixada na parte interna (52) através de quatro parafusos junto aos orifícios (513 e 523). [023] The assembly of the mechanical resiner with the cutting device to perform striation occurs by fixing the stops (2) next to the disc (1), then fitting the blades (3), with height adjustment, next to the stops (2). The inner part (52) of the cover (5) is fitted to the machine (M) using a clamp (6) that surrounds the flap (525) together with the ring (A) of the machine (M), providing stability. The cutting device assembly is coupled to the axis (E) of the machine (M) by fixing its axis (E) in the hole (12). Then, the external part (51) of the cover (5) is fitted to the internal part (52) using four screws next to the holes (513 and 523).
[024] A figura 8 ilustra o resinador montado na máquina (M) e que possui uma alça de apoio (AP) elaborada para distribuir o peso do dispositivo de maneira a assegurar que o operador não tenha que depender exclusivamente da força do braço durante a operação. Essa alça de apoio (AP) é constituída de uma cinta (C) que se ajusta ao corpo do operador, um engate ajustável (EA) para fixar a alça de suporte (AP) em máquinas (M), sendo a fixação e o ajuste realizados por meio de uma fivela (F). [024] Figure 8 illustrates the resiner mounted on the machine (M) and which has a support handle (AP) designed to distribute the weight of the device in order to ensure that the operator does not have to depend exclusively on arm strength during the operation. operation. This support handle (AP) consists of a strap (C) that adjusts to the operator's body, an adjustable coupling (EA) to fix the support handle (AP) on machines (M), with the fixation and adjustment carried out using a buckle (F).
