Description

РУЧНЫЕ САМООЧИЩАЕМЫЕ ВИЛЫ MANUAL SELF-CLEANING FORK
ОБЛАСТЬ ТЕХНИКИ FIELD OF TECHNOLOGY
Изобретение относится к сельскому хозяйству, в частности, к ручным орудиям с зубьями, и может быть использовано для широкого спектра сельскохозяйственных работ. The invention relates to agriculture, in particular to hand tools with teeth, and can be used for a wide range of agricultural work.
ПРЕДШЕСТВУЮЩИЙ УРОВЕНЬ ТЕХНИКИ PRIOR ART
Известны самоочищающиеся грабли [Патент US5713193 от 22.08.1996 «Самоочищающиеся грабли»], состоящие из ручки, рукоятки, пружинной кнопки и двух комплектов зубьев. Ручка выполнена из стеклопластика и состоит из двух телескопических деталей. Одна из частей больше по диаметру, а другая часть удерживается с возможностью скольжения внутри нее. Меньшая часть ручки снабжена чистящим стержнем, к которому прикреплен один набор зубьев, а также чистящий стержень имеет множество выровненных отверстий, через которые проходит второй набор зубцов. Второй набор зубьев прикреплен к первой части рукоятки, а возвратно-поступательное перемещение частей рукоятки относительно друг друга приводит к тому, что чистящий стержень и его прикрепленные зубцы движутся, что приводит к удалению обломков из обоих наборов зубцов. Known self-cleaning rake [Patent US5713193 from 22.08.1996 "Self-cleaning rake"], consisting of a handle, a handle, a spring button and two sets of teeth. The handle is made of fiberglass and consists of two telescopic parts. One of the parts is larger in diameter and the other part is slidingly held within it. The smaller part of the handle is provided with a cleaning rod to which one set of teeth is attached, and the cleaning rod has a plurality of aligned holes through which the second set of teeth extends. The second set of teeth is attached to the first portion of the handle, and the reciprocating movement of the portions of the handle relative to each other causes the cleaning rod and its attached teeth to move, removing debris from both sets of teeth.
Недостатком устройства является то, что наличие двух комплектов зубьев приводит к удалению только крупных обломков, не обеспечивается возможность полной самоочистки. Кроме того, наличие второго комплекта зубьев значительно утяжеляет устройство, снижает полезную площадь зубьев. The disadvantage of the device is that the presence of two sets of teeth leads to the removal of only large debris, the possibility of complete self-cleaning is not ensured. In addition, the presence of the second set of teeth significantly makes the device heavier and reduces the useful area of the teeth.
Известно устройство [Патент ETS3884023 от 20.05.1975 «Самоочищающиеся грабли»], имеющее зубцы с направленными вниз или зависимыми передними концами, снабженное очищающим элементом, перемещаемым скольжением по зубцам. Очищающий элемент окружает зубья и шарнирно соединен с кронштейном, который, в свою очередь, прикреплен к стержню, перемещаемому вдоль рукоятки метлы с помощью ручного актуатора. Чистящий элемент выполнен с возможностью перемещения по заостренным вниз или зависящим от него передним концам зубцов благодаря шарнирному соединению с кронштейном. Очищающий элемент также сжимает зубья, когда он перемещается вниз по зубьям. Known device [Patent ETS3884023 from 20.05.1975 "Self-cleaning rake"], having teeth with downward or dependent front ends, equipped with a cleaning element, sliding on the teeth. The cleaning element surrounds the teeth and is pivotally connected to a bracket, which in turn is attached to a rod that is moved along the broom handle by a hand actuator. The cleaning element is made with the possibility of moving along the pointed downwards or depending on the front ends of the teeth due to the articulated connection with the bracket. The wiper also compresses the teeth as it travels down the teeth.
Недостатком устройства является отсутствие возвратного механизма. Кроме того, очищение зубьев предполагает их сжимание, что в случае сильного загрязнения может привести к деформации зубцов. Кронштейн, расположенный поверх зубьев, сокращает возможность использования устройства в ограниченном пространстве. The disadvantage of the device is the lack of a return mechanism. In addition, cleaning the teeth involves squeezing them, which, if heavily soiled, can lead to deformation of the teeth. A bracket over the teeth reduces the ability to use the device in confined spaces.
Известны самоочищающиеся грабли [Патент US4776158 от 11.10.1988 «Самоочищающиеся грабли для листьев»], включающие удлиненную рукоятку и закрепленную на одном конце раму с разнесенными зубцами. На зубцах устройства расположена пластина, перемещаемая толкателем, закрепленным на рукоятке, по всей длине зубцов. Пружинный зажим удерживает пластину в поднятом положении и может быть освобожден посредством направляющего элемента на рукоятке, взаимодействующей с толкателем. Known self-cleaning rake [Patent US4776158 from 11.10.1988 "Self-cleaning rake for leaves"], including an elongated handle and fixed at one end of the frame with spaced teeth. On the prongs of the device there is a plate, moved by a pusher, fixed on the handle, along the entire length of the teeth. The spring clip holds the plate in the raised position and can be released by means of a guide on the handle interacting with the pusher.
Недостатком устройства является наличие выступающего толкателя на рукоятке, а также отсутствие возвратного механизма. Для возврата пластины в исходное состояние пользователь должен приостановить процесс использования устройства, должен изменить позу и положение рук. Очищающая пластина перемещается толкателем, закрепленным на рукоятке. Длина рукоятки, отсутствие дополнительных креплений и устройств стабилизации положения очищающей пластины при сильном засорении зубьев может привести к поломке устройства. The disadvantage of the device is the presence of a protruding pusher on the handle, as well as the absence of a return mechanism. To return the plate to its original state, the user must pause the process of using the device, must change the posture and position of the hands. The cleaning plate is moved by a pusher attached to the handle. The length of the handle, the absence of additional fasteners and devices for stabilizing the position of the cleaning plate, if the teeth are heavily clogged, can lead to damage to the device.
Наиболее близким к заявляемому устройству, являются самоочищающиеся грабли [Патент US2015257335 от 21.11.2014 «Самоочищающиеся грабли»], включающие в себя полый черенок, имеющий на одном конце раму с множеством удлиненных зубьев, расположенных близко друг к другу. Внутри черенка расположен стержень, на одном конце которого закреплена очищающая пластина, установленная с возможностью скольжения на зубьях. На внешней стороне черенка расположена рукоятка, функционально соединенная со стержнем. Рукоятка позволяет перемещать очищающую пластину вдоль зубьев. Стержень подпружинен пружиной таким образом, чтобы автоматически возвращать очищающую пластину к раме. The closest to the claimed device are self-cleaning rakes [Patent US2015257335 from 11/21/2014 "Self-cleaning rake"], including a hollow handle having at one end a frame with a plurality of elongated teeth located close to each other. A rod is located inside the handle, at one end of which a cleaning plate is fixed, which is slidingly mounted on the teeth. On the outside of the handle there is a handle, which is functionally connected to the shaft. The handle allows you to move the cleaning pad along the teeth. The rod is spring loaded to automatically return the cleaning pad to the frame.
Недостатком устройства является низкая ремонтопригодность в связи с расположением пружины внутри полого черенка. Также применение полого черенка усложняют конструкцию и ограничивают перечень материалов для его изготовления. Кроме того расположение пружины в верхней части черенка увеличивает затраты материала и снижает удобство использования из-за нарушения привычного пользователю баланса инструмента. К тому же известное устройство не может быть создано за счёт модернизации имеющегося у пользователя инвентаря. Помимо этого для очистки зубьев пользователь должен приостановить процесс использования устройства, изменить позу и положение рук. The disadvantage of the device is its low maintainability due to the location of the spring inside the hollow handle. Also, the use of a hollow shank complicates the design and limits the list of materials for its manufacture. In addition, the location of the spring in the upper part of the handle increases material costs and reduces ease of use due to the disturbance of the balance of the instrument, which is familiar to the user. In addition, a known device cannot be created by upgrading the user's existing inventory. In addition, to clean the teeth, the user must pause the process of using the device, change the posture and position of the hands.

Габаритные размеры предлагаемого устройства принимаются соответственно существующим стандартам для подобных конструкций. The movable handle 5 provides the movement of the cleaning plate 4 relative to the handle 1, and, consequently, the compression and expansion of the spring 6. The overall dimensions of the proposed device are taken in accordance with existing standards for such designs.
Принцип действия предлагаемого устройства: в процессе эксплуатации вил очищающая пластина 4 прижата к раме 2 под действием пружины 6. Очистка зубьев 3 производится очищающей пластиной 4, перемещаемой вдоль зубьев 3. Для этого пользователь отводит подвижную рукоятку 4, преодолевая сопротивление пружины 6. При этом рама 2 проходит в продольных пазах 7 и служит одной направляющей для подвижной рукоятки 5, а черенок 1 служит второй направляющей. Вилы возвращаются в исходное состояние разжиманием пружины 6 после того, как пользователь отпускает подвижную рукоятку 5. The principle of operation of the proposed device: during the operation of the forks, the cleaning plate 4 is pressed against the frame 2 under the action of the spring 6. The cleaning of the teeth 3 is carried out by the cleaning plate 4, which moves along the teeth 3. For this, the user removes the movable handle 4, overcoming the resistance of the spring 6. In this case, the frame 2 passes in the longitudinal grooves 7 and serves as one guide for the movable handle 5, and the handle 1 serves as the second guide. The forks return to their original state by unclamping the spring 6 after the user releases the movable handle 5.
Техническим результатом заявляемого изобретения является повышение эксплуатационных характеристик самоочищаемых вил, снижение затрат времени и усилий на очистку зубьев. The technical result of the claimed invention is to improve the performance of self-cleaning forks, reduce the time and effort required to clean the teeth.
