[0023] The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary, and should not be construed as limiting the protection scope of the present utility model.
[0024] It should be noted that: Similar reference numerals denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it may not be further defined and explained in subsequent drawings.
[0025] This embodiment mainly describes the safety distance cover at the end of the shredder, as follows:
[0026] As Figures 1 to 4As shown in the figure, the safety distance cover 3 at the end of the shredder includes the shredder body 1, the feed hopper 2 and the safety distance cover 3. The feed hopper 2 is mainly used to feed the branches and leaves to be shredded into the shredder body 1. The safety distance cover 3 is mainly to ensure that the distance of the feed hopper 2 reaches the specified safety distance range. The feed hopper 2 is fixedly arranged on one side of the body, and the fixed connection method can be welding, screw connection or other methods. The safety distance cover 3 is rotatably arranged at the end of the feed hopper 2. There is a locking part on the safety distance cover 3 and the shredder body 1 to lock the safety distance cover 3 after it rotates. When the safety distance cover 3 rotates around the rotation connection point to fold the safety distance cover 3 and lock it with the locking part, the distance at the feeding end of the shredder is shortened; when the safety distance cover 3 rotates around the rotation connection point to unfold the safety distance cover 3 and communicate with the feed hopper 2 and lock it with the locking part, the distance at the feeding end of the shredder is extended. When the safety distance cover 3 is unfolded and used, the feed hopper 2 not only meets the requirements of safety regulations, but also when the shredder is not in use, the overall packaging size of the machine is reduced after folding, improving the container loading capacity, making packaging and transportation more convenient and greatly reducing the transportation cost; at the same time, closing the safety distance cover 3 can prevent other things from falling into it, eliminating the safety hazards for users during the next use.
[0027] Specifically, the rotation connection method of the safety distance cover 3 is that there are symmetrically arranged first connection holes 34 on both side walls of the safety distance cover 3, and second connection holes 22 corresponding to the first connection holes 34 are respectively arranged on both side walls of the feed hopper 2. A fastening bolt 5 is arranged in the first connection hole 34 and the second connection hole 22. The fastening bolt 5 passes through the first connection hole 34 and the second connection hole 22 in sequence to rotatably connect the safety distance cover 3 to the feed hopper 2. The connection point between the first connection hole 34 and the second connection hole 22 is the rotation connection point in the text. When the safety distance cover 3 is converted from the unfolded state to the folded state, the safety distance cover 3 is driven to rotate clockwise around the first connection hole 34; when the safety distance cover 3 is converted from the folded state to the unfolded state, the safety distance cover 3 rotates counterclockwise around the first connection hole 34.
[0028] Specifically, the locking part is a bolt and a nut that cooperates with the bolt. The nut of the bolt is a large-sized star-shaped cover body. The design of the star-shaped cover body is convenient for hand holding and adjustment when unfolding or folding the safety distance cover 3.
[0029] Specifically, there are two fixed connection structures between the safety distance cover 3 and the feed hopper 2. The first fixed structure is as follows: on both side walls of the safety distance cover 3, there are a first fixing hole 31 and a second fixing hole 32 respectively. On both side walls of the feed hopper 2, there are third fixing holes 21 corresponding to the first fixing holes 31. When the safety distance cover 3 is in the unfolded state, the locking member passes through the first fixing hole 31 and the third fixing hole 21 in sequence to fix the safety distance cover 3 on the feed hopper 2. When the safety distance cover 3 rotates to the folded state, the second fixing hole 32 coincides with the third fixing hole 21, and the locking member passes through the second fixing hole 32 and the third fixing hole in sequence to fix the safety distance cover 3 on the feed hopper 2. The second fixed structure is as Figure 2 and Figure 4 shown. On the basis of the first structure, the area between the first fixing hole 31 and the second fixing hole 32 is designed as a connected arc-shaped slot 33. The center of the arc-shaped slot 33 coincides with the rotation connection point. When the safety distance cover 3 is converted between the folded state and the unfolded state, the fixing bolt 4 of the locking member always slides within the arc-shaped slot 33. When the safety distance cover 3 is in the unfolded state, the locking member slides to the position at the end of the first fixing hole 31. When the safety distance cover 3 is in the folded state, the locking member slides to the end position of the second fixing hole 32. By arranging the fixing bolt 4 within the arc-shaped slot 33, during the unfolding or folding process of the safety distance cover 3, it is only necessary to loosen the nut to release the clamping of the fixing bolt 4 and the nut on the safety distance cover 3 and the feed hopper 2, and then it can be rotated without completely disassembling it. Moreover, the setting of the arc-shaped slot 33 allows the safety distance cover 3 to be folded to the required angle within the range of the arc. In the two fixed connection structures between the above-mentioned safety distance cover 3 and the feed hopper 2, the connection line between the first fixing hole 31 and the rotation connection point is perpendicular to the connection between the second fixing hole 32 and the rotation connection point, and the arc-shaped round hole is a quarter arc designed with the rotation connection point as the center.
[0030] As Figure 1 and Figure 4 shown, the cross-sections of both the feed hopper 2 and the safety distance cover 3 are U-shaped. When the safety distance cover 3 is in the unfolded state, the two side walls of the safety distance respectively abut against the two side walls of the feed hopper 2, and the inner bottom surface of the safety distance cover 3 abuts against the outer bottom surface of the feed hopper 2.
[0031] When it is necessary to fold the safety distance cover 3, loosen the nuts of the fixing bolts 4 on both side walls of the safety distance cover 3, drive the safety distance cover 3 to rotate around the rotation connection point to fold the safety distance cover 3. During the rotation of the safety distance cover 3, the fixing bolt 4 slides within the arc-shaped slot 33 along with the rotation of the safety distance cover 3. When the safety distance cover 3 rotates to the folded state, tighten the nuts of the fixing bolts 4 on both side walls of the safety distance cover 3.
[0032] When it is necessary to unfold the safety distance cover 3, loosen the nuts of the fixing bolts 4 on both side walls of the safety distance cover 3, drive the safety distance cover 3 to rotate reversely around the rotation connection point until the inner bottom surface of the safety distance cover 3 abuts against the outer bottom surface of the feed hopper 2, and then tighten the nuts of the fixing bolts 4 on both side walls of the safety distance cover 3.
[0033] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the present utility model is usually placed during use. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.
[0034] The safety distance cover at the end of the shredder provided by the present utility model has been introduced in detail above. Specific examples are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the present utility model and its core idea. It should be pointed out that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
