[0001] The application relates to the technical field of fruit screening, and particularly relates to a screening machine for quick-frozen fruit processing facilitating efficient screening. BACKGROUND
[0002] With the development of the food processing industry, especially in the field of quick-frozen fruit processing, the requirements for cleaning, screening and grading of fruits are becoming higher and higher. The traditional fruit cleaning and screening equipment often has problems such as incomplete cleaning effect, low screening efficiency, complex equipment structure, large space occupation and the like. In addition, the appearance quality and size requirements of fruits are also important screening standards. How to efficiently and quickly remove unqualified fruits and impurities and effectively grade the fruits according to the size of the fruits has become the key to improving production efficiency and ensuring product quality.
[0003] In the existing fruit screening and cleaning equipment, most of the equipment only rely on manual or simple mechanical devices for screening, and cannot accurately control the size of the fruits and the removal of impurities. The existing equipment often lacks automatic control of the fruits during the cleaning and screening process, resulting in low cleaning efficiency and not meeting the needs of efficient and automated production.

[0010] For better implementation of the application, further, the baffle is slidably arranged on the output groove and is fixedly provided with a control rod.
[0011] The technical scheme provided by the application has the following beneficial effects compared with the prior art:
[0012] 1.

DETAILED DESCRIPTION
[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the application clearer, the technical solutions in the embodiments of the application will be described clearly and completely below in combination with the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. The components of the embodiments of the application described and shown in the drawings herein can be arranged and designed in various different configurations.
[0026] Therefore, the following detailed description of the embodiments of the application provided in the drawings is not intended to limit the scope of the claimed application, but only represents selected embodiments of the application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the application without creative labor are within the scope of protection of the application.
[0027] As Figures 1 to 7As shown, a quick-frozen fruit processing screening machine facilitating efficient screening, comprising a cleaning bin 101, a right backflow plate 102 and an output slot 103 fixedly arranged on the cleaning bin 101, a right transfer box 104 fixedly arranged on the output slot 103, a connecting pipe 105 fixedly arranged on the transfer box 104, the connecting pipe 105 being in communication with the cleaning bin 101, left and right limiting frames 113 and 126 fixedly arranged on the cleaning bin 101, the left limiting frame 113 being L-shaped in cross section, a lower limiting frame 112 slidingly arranged on the left limiting frame 113, a screening net 114 and an upper limiting frame 111 fixedly arranged on the lower limiting frame 112, a plurality of rotating shafts 115 rotatably arranged on the upper limiting frame 111, a cover plate 117 fixedly arranged on the rotating shaft 115, and a plurality of inclined plates 118 fixedly arranged on the cover plate 117.
[0028] Specifically, the upper limiting frame 111 is provided with an upwardly extending baffle, which limits the impurities and unqualified fruits collected on the cover plate 117, so as to avoid falling off from the side when the upper limiting frame 111 is moved.
[0029] In use, the cleaning bin 101 is filled with water, and the fruits to be quick-frozen are conveyed through the backflow plate 102, and then the upper and lower limiting frames 111 and 112 and the screening net 114 are controlled to move up and down, the lower limiting frame 112 is accurately guided into the cleaning bin 101 and closely adheres to the inner wall of the cleaning bin 101 through the limitation of the left and right limiting frames 113 and 126, the fruits in the cleaning bin 101 are pressed by the screening net 114 on the lower limiting frame 112, the fruits are separated from the water flow through the up-and-down reciprocating movement of the screening net 114, so that the impurities on the fruits are washed off, and the fruits are screened according to different specifications by installing different specifications of the screening net 114, the fruits meeting the specification requirements cannot pass through the screening net 114, and the fruits not meeting the specification requirements pass through the screening net 114 by buoyancy to above the water surface, and then when the screening net 114 is controlled to move up after cleaning, the unqualified fruits are blocked by the closed cover plate 117, so as to avoid falling into the cleaning bin 101, and then the fruits are removed.
[0030] During the cleaning process, the upper limiting frame 111 moves up and down, the cover plate 117 on the upper limiting frame 111 is in a horizontal state in the initial state, Figure 1As shown in the state, when the control upper limit frame 111 enters the cleaning bin 101 and goes deep, the water in the cleaning bin 101 exerts a pushing force on the cover plate 117, because the inclined direction between the inclined plate 118 and the cover plate 117 is away from the rotating shaft 115, so that the water flow exerts a smaller pushing force on the inclined plate 118, thereby making the cover plate 117 rotate on the rotating shaft 115, and the cover plate 117 changes from horizontal to inclined state, when the control upper limit frame 111 moves upward, because the water flow will enter the space between the cover plate 117 and the inclined plate 118, thereby increasing the resistance to the inclined plate 118, thereby pushing the cover plate 117 to reset, that is, from inclined to horizontal, the state of multiple cover plates 117 contacting each other, this process is completed before the upper limit frame 111 leaves the water surface, so that the impurities and unqualified fruits floating on the water surface are blocked by the cover plate 117 and cannot fall below the screening net 114, thereby being lifted by the cover plate 117, and the upper layer of water falls through the cover plate 117 into the cleaning bin 101. After moving out of the water surface, the control upper limit frame 111 is lifted to process the impurities and unqualified fruits.
[0031] As shown in Figure 4 and Figure 5 As shown, four lifting rods 110 are fixedly arranged on the upper limit frame 111, two of which are rotatably provided with left connecting rods 109, and the other two are rotatably provided with right connecting rods 123. The left connecting rods 109 are rotatably provided with side cross rods 108, and the right connecting rods 123 are provided with sliding grooves, the sliding grooves are slidably provided with sliding shafts 120, and the sliding shafts 120 are rotatably connected with the side cross rods 108.
[0032] Specifically, the side cross rods 108 are fixedly connected with mounting frames 107, the mounting frames 107 are provided with air cylinders 106, the mounting frames 107 are controlled by the air cylinders 106, and the upper limit frame 111 and the like are controlled to move up and down.
[0033] The sliding shafts 120 are slidably provided with sliding rods 121, the sliding rods 121 are fixedly connected with the right connecting rods 123, the sliding rods 121 are sleeved with buffer springs 122, and the two ends of the buffer springs 122 are fixedly connected with the sliding shafts 120 and the right connecting rods 123 respectively.
[0034] Specifically, the two left connecting rods 109 and the two right connecting rods 123 are located on the two sides respectively, and the right connecting rods 123 are located on the same side with the right limit frames 126. The position of the sliding shaft 120 in the sliding groove of the right connecting rod 123 is limited by the pushing force and the pulling force of the buffer spring 122. Initially, the gravity of the upper limit frame 111 and the like will stretch the buffer spring 122, so that the sliding shaft 120 is located at the lower part of the sliding groove of the right connecting rod 123, but there is a certain distance from the end point of the sliding groove, so that the upper limit frame 111 is in a downward inclined state toward the right limit frame 126, that is Figure 5When the control side crossbar 108 moves downward, the resistance of the water in the cleaning bin 101 will temporarily push the upper limit frame 111 and other structures, causing the buffer spring 122 to deform, so that the buffer spring 122 is compressed, the upper limit frame 111 is inclined to be horizontal, and the horizontal state of the lower limit frame 112 is kept stable and accurate through the restriction around the cleaning bin 101 and the lower limit frame 112.
[0035] When the side crossbar 108 moves upward, the side crossbar 108 pulls the buffer spring 122, driving the right connecting rod 123 and the upper limit frame 111 to move upward, the right limit frame 126 is fixedly provided with a limiting rod 119, the lower limit frame 112 is slidingly connected with the right limit frame 126, and the right limit frame 126 is rectangular in cross section.
[0036] Specifically, when the lower limit frame 112 slides on the left limit frame 113 and the right limit frame 126, the L-shaped corner of the left limit frame 113 limits the moving route of the lower limit frame 112 in the vertical and horizontal directions, and the right limit frame 126 only limits the movement of the lower limit frame 112 in the vertical direction. When the cylinder 106 drives the lower limit frame 112 to move, the moving route will slightly tilt towards the direction of the left limit frame 113, so that the lower limit frame 112 can always be in close contact with the two left limit frames 113, thereby ensuring the accurate cooperation of the lower limit frame 112 with the cleaning bin 101.
[0037] When it is necessary to clean and collect the impurities and unqualified fruits on the cover plate 117, the side crossbar 108 is controlled to move upward, the side crossbar 108 also drives the left connecting rod 109 to move, thereby driving the surrounding lifting rods 110 to move, and then controlling the lower limit frame 112 to move. The side crossbar 108 pulls the buffer spring 122, driving the right connecting rod 123 and the upper limit frame 111 to move upward.
[0038] When the right connecting rod 123 touches the limiting rod 119, the right connecting rod 123 stops moving, the side crossbar 108 continues to move and stretch the buffer spring 122, so that one end of the right connecting rod 123 on the upper limit frame 111 is stationary, and the other end of the upper limit frame 111 on the left limit frame 113 continues to move upward, so that the upper limit frame 111 presents a large inclination state, and the inclination direction is from the upward direction of the left limit frame 113 to the downward direction of the right connecting rod 123. The inclination state makes the inclined surface of the inclined plate 118 on the cover plate 117 parallel to the horizontal plane, so that the impurities and unqualified fruits on the cover plate 117 can be removed.
[0039] As shown in Figure 6 and Figure 7 The shaft 115 is fixedly provided with a spring 116, and the spring 116 is also fixedly connected with the upper limit frame 111.
[0040] When the cover plate 117 is resisted by the water in the washing bin 101, as the upper limit frame 111 continues to move downward, the water pushes the cover plate 117 to rotate the rotating shaft 115 on the upper limit frame 111, so that the rotating shaft 115 twists the spring 116, and when the inclined plate 118 on the cover plate 117 contacts the upper limit frame 111, the rotation is stopped, and when the upper limit frame 111 moves upward, the inclined plate 118 and the cover plate 117 are reset by the resistance of the water, and at the beginning, the reset is promoted by the torsion of the spring 116.
[0041] As shown in Figure 2 The output slot 103 is slidably provided with a baffle 124, and the baffle 124 is fixedly provided with a control rod 125.
[0042] Specifically, after the screening and washing are completed, the control rod 125 is manually controlled to lift the baffle 124, so that the baffle 124 slides upward on the washing bin 101, so that the water and the fruits on the upper layer in the washing bin 101 are moved out through the gap of the baffle 124 and fall onto the output slot 103, and then are filtered through the gap and the filter screen provided on the output slot 103, so that the water enters the transfer box 104 and is circulated through the connecting pipe 105, while the fruits stay on the output slot 103 and are collected.
[0043] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
