Description

 The present invention relates to means of small-scale mechanization and can find application in devices used for processing products of horticulture and gardening and is intended, in particular, for extracting juice from fruits and vegetables at home (farm) conditions.

 A device is known (see A.c. 1205885, A 47 J 19/00), comprising a bed, a working screw with a nut, a pressure plate mounted on the working screw, a bottom, a juice collector bottom and a pressing basket with slotted holes in the wall for juice passage, the plate is mounted with a removable convex side up and vertical slots are made in it, diverging to the periphery, while a mesh is located on the bottom of the juice collector, the diameter of which exceeds the diameter of the pressing basket, and the edge of the mesh is raised above the level of the latter.

 A disadvantage of the known device is that the design provides for the flow of juice through openings located in the lower part of the press chamber and on the side around the entire perimeter of the container. In this case, squeezing the juice and pushing it through these holes is extremely difficult, as they are instantly clogged with the skin, which reduces the extraction of juice and reduces its quality.

 The closest in technical essence and the achieved result to the invention is a device (see A.S. 1253616, A 47 J 19/00, 1984), including a frame, a vertically mounted pressing chamber with solid walls and a nozzle for drainage of juice located on the side the wall of the press chamber in its upper part, the main mesh filter, an additional mesh filter, the mesh sizes of which are smaller than the dimensions of the main filter, a punch with holes for the juice outlet and the power mechanism interacting with it, intermediate elements bets placed between the power mechanism and the punch, while the main filter is installed under the additional one.

 The disadvantages of the known device are the inconvenience associated with the fact that although the punch is made voluminous and is at the same time a displacement container that drains the juice through the nozzle, there is always a large amount of juice in the press chamber that the punch cannot displace to the upper drain pipe, therefore, the juicer must be tilted to a horizontal position to drain the remaining juice.

 The aim of the present invention is to improve the quality of juice and increase ease of use.

 This goal is achieved by the fact that in the known device containing a frame, a vertically mounted pressing chamber with solid walls and a tube for draining juice, the main and additional cellular filters are placed in the chamber, while the main filter is installed under the additional, and the cell sizes are additional the filter is smaller than the mesh size of the main filter, a piston with holes for juice exit is located under the additional filter, the power mechanism interacting with the frame and the piston, and according to the image In addition, a second drain pipe is introduced, both pipes are located on the side surface of the chamber in its lower part, the first pipe is located in a position above the piston disk with the product compressed as much as possible, the second pipe is located directly above the first pipe (or simultaneously with mixing to the left (to the right) of it ), and during the pressing period both tubes are closed with screw plugs, the lengths of which in the screwed state are equal to the lengths of their tubes.

 The invention is illustrated in FIG. 1 2 with a general view of the device.

 The juicer consists of a frame including side racks 1 and the upper 2 and lower 3 support beams connected to them, on which flat plates are fixed. A press chamber 4 is installed on the bottom plate, the walls and bottom of which are solid. On the compressible product (fruits or vegetables) in the chamber (not shown) the main filter 5 is placed, on it an additional filter 6 with smaller cells. Filters are round metal grids with mesh sizes of 1.2 mm and 0.5 mm, respectively.

 A piston disk 7 is attached at the top, connected to the shank 8, which is connected to the power mechanism by a lead screw 9 and fixed on it by a screw 10. The power mechanism is built on the principle widely used in screw jacks with cross over ratchet. So the lead screw is connected via an arm 11 to the upper support plate 12 by means of a nut 13, which has protruding grooves in its lower part along the perimeter.

 The rotation of the nut is carried out in the horizontal plane by the handle-lever 14, which is a long rod 0.6 m long (shown by a dash), inserted into the hole 15 of the bracket 16. The interaction of the bracket 16 with the nut 13 is provided by a cross over ratchet 17 that rotates around the axis 18 and the protrusion which enters the groove of the nut 13, as a result of which, in one direction of rotation, the torque from the handle-lever 14 is transmitted to the nut 13, the working stroke, in the opposite direction, the ratchet protrusion glides along the grooves of the nut ostoy move.

 Transferring the ratchet handle 19 to the "Left" or "Right" position, followed by the oscillatory movement of the lever handle 14 in a horizontal plane at angles up to +50 degrees. measured from the normal to the plane of the frame, leads to the lowering of the lead screw with the piston (pressing process) or, accordingly, to the rise.

 To prevent rotation of the lead screw, a side groove is provided in it, into which a key 20 enters, mounted on a sleeve 21, which is mounted on top of the upper support plate 12.

 On the side surface of the chamber in its lower part there are drain pipes 22 and 23 (for clarity in the drawing, they are turned 90 degrees to the right, that is, they are shown in the plane of the sheet), closed with screw plugs during the pressing period, the lengths of which are equal to the lengths their tubes, which is necessary to prevent clogging by the particles of the squeezed product during pressing.

 The first drain pipe 22 is placed in position above the disc-piston 7 with the most compressed product. This situation is definitely experimental and depends on the diameter (area) of the base and the height of the chamber (filling it with the processed product), the compressive strength and types of the most frequently processed products, more precisely their juiciness. The second tube 23 is located directly above the first tube 22 (or simultaneously with the mixture to the left (right) of it). The left (right) displacement of the tube 23 is necessary for the convenience of unscrewing the screw plugs and so that when draining the juice flowing out of the tube 23 does not fall onto the tube 22.

 The operation of the device is as follows.

 Before operation, the drain pipes 22 and 23 must be completely closed with their screw plugs. The cleaned and medium-sized (for better filling) product is loaded into the chamber 4, the main (coarse) filter 5 is placed on top of it, then the additional (fine-meshed) filter 6 (substitute folded in two or three layers of gauze).

 The contents chamber is placed on the lower base under the piston disk 7, which is previously raised by the spindle 9 to the upper position. Using the handle 19, the ratchet 17 is moved along the groove in the bracket 16 to the “Left” position and the oscillating movement of the handle lever 14 in the horizontal plane begins pressing by pushing the lead screw with the piston down. Under the action of a piston 7 moving downward in the pressing chamber 4, the juice is squeezed out of the product, while the juice is forced out of the pressing chamber, passing successively through filters 5 and 6, is cleaned of solid particles, passes through the holes in the piston 7 and accumulates in the upper part of the chamber.

 The height distribution of the drain tubes 22 and 23 allows you to extract juice from the product in stages, i.e. first, the purest (more transparent) juice is extracted by pressing the product with a piston to a level slightly lower than the position of the second tube 23, after which the screw-plug of this tube is unscrewed and the pure juice is drained into a separate container. Then the pressing process continues and ends when the piston drops below the level of the first drain pipe 22. The screw plug is unscrewed and the remaining juice (darker, mixed with puree) is drained through an open tube into another container.

 Transferring the ratchet handle 19 to the opposite “Right” position and the oscillating movement of the handle lever 14, the lead screw with the piston easily rises to the upper position. Filters 5, 6 are removed from the chamber and it is cleaned of the squeezed product (pulp). Filters, a chamber, screw plugs, a piston with a shank are thoroughly washed with water, after which the device is again ready for operation.

 The proposed device allows at the first stage to obtain due to separate pressing juice of better quality: the purest, easiest to separate, without impurity puree. The second stage of pressing allows you to completely extract the juice from the product (with a small admixture of mashed potatoes), but without solid particles and pour into another container.

 The device also allows you to take into account the fact that if the product is small (incomplete filling of the chamber), the pressing process should be carried out similarly, but at the first stage the second tube 23 is not opened, and the first tube 22 will fulfill the usual role of the second and as a result, high-quality juice will also be obtained , and the remaining juice after further pressing merges differently. The shank 8 of the piston 7 is released from the lead screw 9 with the screw 10. Then the lead screw rises to the upper position, the chamber with the contents and the piston with the stem (hand-tightened) tilts and the juice is drained into a separate container.

 An example of a specific implementation is a device that has parameters.

 Press chamber, piston with shank, drain tubes, screw plugs are made of 12X18H9T stainless steel. The lead screw, nut, bracket, ratchet are made of steel 45, the frame is made of channel 5, the remaining parts are made of ordinary steel. For the convenience of storage and transportation, the frame is collapsible and assembled on M12 bolts. The main and additional filters are round grids with mesh sizes of 1 mm and 0.5 mm, respectively. For rigidity, mesh filters are sealed around the perimeter with wire.

 The proposed device is simple in design and due to the absence of clogging of the holes with particles of the squeezed product, it is possible to quickly and efficiently obtain pure juice from fruits and vegetables at home (farm) conditions.

 The device is more convenient in operation compared to the known device in that there is no need to drain the remaining juice by tilting the entire juicer to a horizontal position, and during pressing periodically return the jack back to its original position, put spacers in order to continue pressing.

 The practice of using a juicer has shown high efficiency and ease of use with ease of maintenance. The device allows not only to fully extract the juice, but also to separate the high-quality juice in the process of pressing into a separate container, which allows us to conclude that the achievement of the objectives of the invention.

 The device can be widely used in collective gardening.
