Description

Technical fields:

[0001] This utility model relates to the technical field of racks for drying raisins, and more specifically to a matching hanging rack for a drying oven used in raisin processing. Background technology:

[0002] Grape drying is the process of removing moisture from fresh grapes through heat treatment to make raisins. Currently, there are two main methods for drying grapes: one is natural sun-drying, which involves direct exposure to sunlight or drying in a shaded room. This is simple and easy, but the drying cycle is long, greatly affected by the weather, and hygiene conditions are difficult to guarantee. The other is artificial heating drying, which uses drying equipment such as ovens and drying rooms. This method is less affected by weather factors and is suitable for industrial production. When drying grapes in ovens or drying rooms, bunches of grapes need to be hooked up and hung on a hanging rack. The hanging rack can then be used to suspend the grapes in and out of the oven or drying room.

[0003] However, existing hanging racks generally have multiple horizontally arranged support frames, which are vertically distributed on the hanging rack. At the same time, there are several horizontally evenly spaced hanging rods inside, on which grapes are hung. However, during use, the outer hanging rods can obstruct the flow of grapes, making it inconvenient to hang the grapes on the inner hanging rods of the support frame. Therefore, it is necessary to design a hanging rack for drying grapes that is convenient for hanging. Utility Model Content:

[0004] The purpose of this utility model is to address the shortcomings of existing technology by providing a matching hanging rack for a drying oven used for raisin processing. The matching hanging rack allows the vertically distributed support frame to be tilted and adjusted, so that the hanging rods on the support frame are staggered in the vertical direction. The outer hanging rods no longer affect the hanging of grapes on the inner hanging rods, making it convenient for hanging grapes.

[0005] A hanging frame for a drying oven for raisin processing includes a rectangular bottom beam frame. A column is fixed to the middle of the front and rear side frames of the bottom beam frame. Several sets of vertically distributed supports are provided on both sides of the column. Each support includes two sets of obliquely placed support rods (front and rear) and a longitudinal limiting shaft. The inner end of the support rod is hinged to an ear seat via a pin. The ear seat is fixed to the support rod. A raised strip is formed on the upper surface of the support rod near its outer end. An oblique first guide groove is formed on the raised strip. Vertical support plates are fixed to the bottom beam frame on both sides of the column. Several vertically distributed second guide grooves are formed on the support plates, opposite to the first guide grooves. Circular limiting sleeves are inserted and fixed to the two ends of the limiting shaft through the first guide groove of the support rod and the second guide groove of the support plate. Parallel grooves are formed on the upper and lower opposite outer walls of the limiting sleeve. The bottom surface of the groove on the lower side of the limiting sleeve abuts against two sets of limiting blocks. The limiting blocks are formed on the support plates on both sides of the second guide groove.

[0006] The support frame has several longitudinal suspension rods fixedly connected between its support rods, and several longitudinally distributed hanging rings are formed on the suspension rods; a receiving tray is inserted between the columns, the receiving tray abuts against the bottom beam frame, and several arrayed ventilation holes are formed on the receiving tray; wheels are fixedly connected to the four corners of the lower end face of the bottom beam frame.

[0007] Preferably, the hanging rings are linearly and evenly distributed on the suspension rods, the suspension rods are linearly and evenly distributed on the support rods, and the support rods are linearly and vertically evenly distributed on both sides of the column;

[0008] The second guide groove and the limiting sleeve are both linearly and evenly distributed on the support rod.

[0009] Preferably, the diameter of the limiting shaft is equal to the width of the first guide groove, and the width of the first guide groove is equal to the width of the second guide groove;

[0010] The distance between the bottom surfaces of the grooves on both sides of the limiting sleeve is less than the distance between the limiting blocks on both sides of the second guide groove.

[0011] Preferably, the diameter of the outer wall of the limiting sleeve is greater than the distance between the limiting blocks on both sides of the second guide groove.

[0012] Preferably, a crossbeam is fixed to the top of the column, and both ends of the crossbeam are fixedly connected to the support plate. Triangular stiffeners are fixedly connected to the side wall of the support plate and are fixedly connected to the crossbeam.

[0013] Preferably, the length of the receiving tray is greater than twice the length of the support rod.

[0014] The beneficial effects of this utility model are as follows:

[0015] This hanging frame allows for tilt adjustment of the vertically distributed supports, resulting in staggered vertical distribution of the hanging rods on the supports. This ensures that the outer hanging rods do not interfere with the grapes being hung on the inner hanging rods, facilitating the hanging of grapes. Attached image description:

Detailed implementation method:

[0020] Example: See Figures 1 to 3 As shown, a hanging frame for a drying oven for raisin processing includes a rectangular bottom beam frame 1. Columns 2 are fixedly connected to the middle of the front and rear side frames of the bottom beam frame 1. Several sets of vertically distributed supports are respectively arranged on both sides of the columns 2. Each support includes two sets of diagonally placed support rods 3 (front and rear) and a longitudinal limiting shaft 6. The inner ends of the support rods 3 are hinged to lugs 4 via pins. The lugs 4 are respectively fixed to the support rods 3. A protrusion 31 is formed on the upper surface of the support rod 3 near its outer end. An obliquely placed first guide groove 32 is formed on the protrusion 31. The bottom beam frame 1 has several sets of vertically distributed supports on both sides of the columns 2. Vertical support plates 5 are fixedly connected to the beam frame 1. Several vertically distributed second guide grooves 51 are formed on the support plates 5 and are opposite to the first guide groove 32. The two ends of the limiting shaft 6 pass through the first guide groove 32 of the support rod 3 and the second guide groove 51 of the support plate 5 respectively and are fixedly connected to the circular limiting sleeve 7. The upper and lower opposite outer walls of the limiting sleeve 7 are respectively formed with parallel cuts 71. The bottom surface of the cuts 71 on the lower side of the limiting sleeve 7 abuts against two sets of limiting blocks 52. The limiting blocks 52 are formed on the support plates 5 on both sides of the second guide groove 51.

[0021] Several longitudinal suspension rods 9 are fixedly connected between the support rods 3 of the support frame, and several longitudinally distributed hanging rings 91 are formed on the suspension rods 9; a receiving tray 8 is inserted between the columns 2, the receiving tray 8 abuts against the bottom beam frame 1, and several arrayed ventilation holes 81 are formed on the receiving tray 8; wheels 30 are fixedly connected to the four corners of the lower end face of the bottom beam frame 1 respectively.

[0022] The hanging rings 91 are linearly and evenly distributed on the suspension rods 9, the suspension rods 9 are linearly and evenly distributed on the support rods 3, and the support rods 3 are linearly and evenly distributed on both sides of the column 2.

[0023] The second guide groove 51 and the limiting sleeve 7 are both linearly and evenly distributed on the support rod 3.

[0024] The diameter of the limiting shaft 6 is equal to the width of the first guide groove 32, and the width of the first guide groove 32 is equal to the width of the second guide groove 51.

[0025] The distance between the bottom surfaces of the grooves 71 on both sides of the limiting sleeve 7 is less than the distance between the limiting blocks 52 on both sides of the second guide groove 51. Thus, by rotating the limiting shaft 6, the limiting sleeve 7 can be rotated 90 degrees, and the limiting sleeve 7 can move downward between the limiting blocks 52.

[0026] The diameter of the outer wall of the limiting sleeve 7 is greater than the distance between the limiting blocks 52 on both sides of the second guide groove 51; thus, the limiting sleeve 7 will be blocked by the limiting blocks 52.

[0027] The top of the column 2 is fixed with a crossbeam 10, and the two ends of the crossbeam 10 are respectively fixed to the support plate 5. A triangular stiffener 40 is fixed to the side wall of the support plate 5. The stiffener 40 is fixedly connected to the crossbeam 10 to improve the strength of the suspension frame.

[0028] The length of the receiving tray 8 is more than twice the length of the support rod 3; when the support rod 3 is lowered, the receiving tray 8 can catch the falling grapes.

[0029] Handles 20 are fixed to the middle and upper parts of the column 2 on the front side of the bottom beam frame 1. The suspension frame can be moved easily through the handles 20. Its wheels are made of high temperature resistant wheels (such as metal wheels) and can withstand the temperature of drying grapes in the oven.

[0030] Working principle: This structure is a suspension frame, and its suspension frame structure is as follows: Figure 1 As shown, the support frame on its suspension frame is set at an angle, and the suspension rods 9 set on the support rod 3 are misaligned and not in the same horizontal range; at the same time, the grapes are hung according to the principle of bottom to top and inside to outside. For example, the distance between the outer side of the support frame at the bottom of the suspension frame and the bottom beam frame 1 is greater than the distance between the inner side of the support frame and the bottom beam frame 1. That is, the space at the entrance of the support frame is greater than the space on the inner side, which makes it easier for the grapes to move to the inner side of the support frame and does not interfere with the suspension rods 9, making the operation more convenient.

[0031] When hanging the grapes on the upper support frame, the limiting shaft 6 needs to be rotated to release the limiting sleeve 7 from the constraint of the limiting block 52, thereby placing the lower support frame horizontally. This makes the space at the entrance between the supports larger than the inner space, which, for the same reason, facilitates the hanging of the grapes.

[0032] The embodiments described above are illustrative of the present invention and are not intended to limit the present invention. Any person skilled in the art can modify the embodiments without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be as set forth in the claims.
