Description

Technical Field

[0001] The utility model relates to the technical field of squeezers, and more specifically to a squeezer driven by a screw jack. Background Art

[0002] Expeller press is an important equipment used to extract oil or other liquids from plant materials. It is widely used in agriculture and food processing industries due to its high efficiency and reliability.

[0003] In some small processing plants, for example, oil mills and juice processing workshops at the entrance of the village, rapeseed or fruit are usually squeezed by pure mechanical physical pressing. The core component of pure mechanical physical pressing is a threaded rod, which drives the pressure plate downward by rotating the threaded rod to achieve the squeezing of rapeseed or fruit. Although the threaded rod can self-lock during the downward movement, it still needs to apply a large torque, which consumes a lot of physical energy. In addition, the oil mills and juice processing workshops at the entrance of the village are usually mostly elderly people, and they may lack strength after long-term use, resulting in incomplete squeezing. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a press driven by a screw jack, which solves the problem that during the use of the press in the prior art, the personnel consume a lot of physical energy, and it is easy to lose strength after long-term use, resulting in incomplete pressing.

[0006] 2. Technical solution

[0007] To solve the above problems, the utility model adopts the following technical solutions.

[0009] An upper movable beam is arranged between a pair of the frames, a screw jack body is fixedly connected to the middle part of the lower end of the upper movable beam, and a lower output end of the screw jack body is in contact with the upper surface of the pressing plate.

[0010] Furthermore, the inner walls of a pair of the frames are fixedly connected to a limit plate, one side of the pair of the frames is provided with a through hole 1 and a through hole 2, the through hole 2 is located above the through hole 1, both ends of the upper movable beam are provided with positioning holes, and one side of the pair of the frames is provided with a limit pin, the limit pin passes through the through hole 2 and is embedded in the positioning hole.

[0011] Furthermore, a placement cylinder is fixedly connected to one side of the frame, and a lever arm is embedded in the upper end of the placement cylinder.

[0012] Furthermore, a pair of handles 1 are fixedly connected to the upper end of the pressure plate, and a handle 2 is fixedly connected to the upper end of the upper movable beam.

[0014] Furthermore, a first limited position placement groove is provided on the upper surface of the support plate, and a second limited position placement groove is provided on the upper surface of the liquid transition basin.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] (1) In this scheme, the liquid transition basin is first placed on the support plate, and then the porous mesh barrel is placed on the liquid transition basin. After adding the squeezed raw materials into the porous mesh barrel, a pressure plate is placed, and then the screw jack body handle is rotated clockwise. The ejection shaft of the screw jack body will be quickly ejected downward. When it contacts the pressure plate, the force arm rod is inserted into the screw jack body handle and swung up and down. At this time, the screw jack body is able to slowly push the pressure plate downward to squeeze out the juice contained in the squeezed raw materials. After the juice enters the liquid transition basin, it finally flows out from the discharge port, thereby achieving the squeezing of the raw materials. The screw jack body drives the pressure plate to be pressed down. The ratchet mechanism and gear mechanism inside the screw jack body make it easier for personnel to operate. Even the elderly can use it for a long time to avoid the phenomenon of lack of strength due to long-term use, resulting in incomplete squeezing.

[0018] (2) In this scheme, when the ejection stroke of the screw jack body in a single operation is not sufficient for complete squeezing, the handle is rotated counterclockwise to return the ejection shaft of the screw jack body to the bottom, the upper movable beam is lifted with one hand, and the two limit pins are pulled out. When the upper movable beam is lowered to the limit plate, the two limit pins are inserted through the through holes and fit into the positioning holes on the upper movable beam, thereby keeping the upper movable beam stable. Then the handle of the screw jack body is rotated clockwise again, and the squeezing operation is repeated until the juice in the raw material is completely squeezed dry, thereby further improving the squeezing effect.

[0031] The specific model of the screw jack body 9 is a 3T screw jack, and its internal structure and working principle are existing known technologies, so no further description is given here.

[0032] like Figure 1-4 As shown, the inner walls of a pair of frames 2 are fixedly connected to the limit plate 21, one side of the pair of frames 2 is provided with a through hole 1 22 and a through hole 24, the through hole 24 is located above the through hole 1 22, both ends of the upper movable beam 8 are provided with positioning holes 81, and one side of the pair of frames 2 is provided with a limit pin 23, the limit pin 23 passes through the through hole 24 and is embedded in the positioning hole 81.

When the upper movable beam 8 is lowered to the limit plate 21, the two limit pins 23 are passed through the through hole 1 22 and are engaged with the positioning holes 81 on the upper movable beam 8, so that the upper movable beam 8 remains stable, and then the handle of the screw jack body 9 is rotated clockwise again, and the squeezing operation is repeated until the juice in the raw material is completely squeezed dry, thereby further improving the squeezing effect;

[0034] By performing double-stroke pressing, the initial height of the porous mesh barrel 6 can be twice the stroke of the screw jack body 9, and the porous mesh barrel 6 can be loaded with more raw materials at one time.

[0035] like Figure 1-2 As shown, a placing cylinder 25 is fixedly connected to one side of a frame 2, and a lever arm 26 is embedded at the upper end of the placing cylinder 25.
