Description

Technical Field

[0001] The utility model belongs to the technical field of crushing devices, and in particular relates to a straw crushing device. Background Art

[0002] Straw usually refers to the remaining part of crops such as wheat, corn, and rapeseed after harvest. In the past, straw was mostly burned directly on site after harvest. However, in recent years, with the requirements of environmental protection, higher requirements have been placed on the treatment of straw. At the same time, with the improvement of people's living standards, keeping pets has become the mainstream in cities, and the places required for pets to excrete mostly require sand and gravel. Therefore, using straw to make excretion materials has become a method of environmentally friendly treatment of straw.

[0003] At present, when using straw to make excretion sand and gravel, in order to ensure the convenience of subsequent processing and sufficient mixing with other materials, the straw needs to be crushed accordingly. When general crushing equipment is used for processing, the staff directly puts the straw into the crushing. Since the straw will become fine particles or powdery materials after crushing, although the discharge port will use hoppers and bags for guidance and shielding, the feed port will gush out a large amount of dust, debris, etc. during the crushing process, which will not only pollute the processing site, but also easily threaten the staff, which is not conducive to processing needs.

[0021] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0022] Example 1: Figure 1-3 As shown, a straw crushing device comprises a crushing mechanism and a control panel. The crushing mechanism is in a cylindrical structure as a whole and its axis is parallel to the ground. A feed inlet and a discharge inlet are respectively arranged at the axis end and the lower end of the crushing mechanism. An auxiliary mechanism is arranged at the feed inlet of the crushing mechanism.

[0023] The auxiliary mechanism includes a bottom plate 1, a protective cover 11 and a lever assembly. The bottom plate 1 is fixedly connected to the crushing mechanism and is located at the lower side of the feed port. The protective cover 11 is fixedly connected to the bottom plate 1 and matches the shape of the feed port. The lever assembly is arranged on the protective cover 11.

[0024] The lever assembly includes a through-and-close plate 2, a hinged rod 21 and a port plate 22. The hinged rod 21 is hingedly arranged at the middle part of the upper end of the protective cover 11 through a bracket. The through-and-close plate 2 is slidably connected to the protective cover 11 on the side close to the crushing mechanism. The port plate 22 is slidably connected to the opening of the protective cover 11 through guide ribs. The upper ends of the through-and-close plate 2 and the port plate 22 are both slidably hinged to the lower side of the hinged rod 21. The length of the through-and-close plate 2 is greater than twice the height of the protective cover 11. The through-and-close plate 2 is provided with a through opening 23 that matches the position of the hinged rod 21 at the maximum flipping height.

[0025] When the straw is crushed, the crushing mechanism is turned on through the control panel, and then the port plate 22 is pushed upward so that the port plate 22 leaves the opening of the protective cover 11. Correspondingly, when the port plate 22 moves upward, it pushes the other end of the hinged rod 21 to flip downward, thereby causing the through-and-closed plate 2 to slide downward and misalign its through-and-closed plate 23 with the protective cover 11, that is, the protective cover 11 is closed. At this time, the crushing space of the crushing mechanism is blocked. On the one hand, it can prevent some longer straws from extending into the crushing mechanism in the preparation stage and being crushed in advance, thereby preventing impurities such as powder, dust, and debris from pouring out from the feed port and causing greater pollution and interference and threat to the staff. On the other hand, it can prevent the staff from accidentally entering the crushing mechanism and causing danger. Furthermore, in order to maintain the stability of the port plate 22 and the through-and-closed plate 2, a damping hinge can be used between the hinged rod 21 and the bracket, and any component such as a magnet or a buckle that can limit the port plate 22 can also be set at the upper and lower ends of the protective cover 11 corresponding to the maximum active stroke of the port plate 22, wherein when the magnet is set, the port plate 22 is supported by a magnetic metal.

[0026] When the bundled straw is placed between the through-plate 2 and the end plate 22 in the protective cover 11, the end plate 22 is pulled downward at this time, and the protective cover 11 is closed by the hinged rod 21 in the opposite manner as mentioned above, and the through-plate 2 is moved upward so that the through-port 23 corresponds to the channel of the protective cover 11. In order to facilitate the automatic entry of the straw into the crushing mechanism, a vibration motor 31 can be arranged on the bottom plate 1, or the vibration force of the equipment itself can be utilized when the crushing mechanism is running, and the entire auxiliary mechanism can be tilted to achieve the automatic sliding of the straw into the crushing mechanism for crushing. Such a crushing method is safer and more environmentally friendly. Compared with the traditional crushing device, it can prevent the staff from accidentally touching the crushing mechanism and causing accidents, and it can also prevent impurities from flying out during the crushing process. At the same time, because the through-plate 2 and the end plate 22 are under the lever action of the hinged rod 21, their operating actions are synchronized and their states are opposite, so that the preparation time required for processing can be greatly saved. Compared with some crushing devices that are also provided with shielding components, its operation is more convenient and there is no need to open and close and operate components many times.

[0027] The crushing mechanism comprises a crushing box 3, a motor 31 and a knife group. The knife group is arranged in the crushing box 3. The motor 31 is fixedly arranged on the side of the crushing box 3 and is drivingly connected with the knife group.

[0028] The length of the bottom plate 1 is greater than that of the protective cover 11 ; the length of the bottom plate 1 being greater than that of the protective cover 11 enables the bottom plate 1 to extend backward, which can assist in placing straw in the preparation stage, making the operation more convenient.

[0029] A handle 4 is also provided on the side of the port plate 22 ; this makes it more convenient to operate the port plate 22 .

[0030] Example 2: Figure 1 and 3As shown, based on the further improvement of Example 1, the port plate 22 is further provided with a pusher matching the length direction of the base plate 1, the pusher comprises a push plate 5 and a U-shaped rod 51, the U-shaped rod 51 slides through the port plate 22, there are two push plates 5 and they are respectively connected to the two ends of the U-shaped rod 51 passing through the port plate 22, and the port plate 22 is provided with a mating groove 52 matching the push plate 5.

[0031] Furthermore, since some straw may not be able to automatically slide into the crushing mechanism during the crushing process, the U-shaped rod 51 can be pushed at this time to ensure smooth crushing, and the push plate 5 on the open side of the U-shaped rod 51 can be used to push the straw retained in the protective cover 11 to promote smooth crushing, and then the U-shaped rod 51 is retracted and the push plate 5 is ensured to be in the engaging groove 52, so as to ensure that the push plate 5 will not affect the smooth up and down sliding of the port plate 22.

[0032] Embodiment 3: A further improvement on the basis of Embodiment 2, a resetter is provided on the parallel parts on both sides of the U-shaped rod 51, the resetter includes a limit plate and a spring, the limit plate is fixedly connected to the U-shaped rod 51, and the spring is sleeved on the U-shaped rod 51 and located between the limit plate and the port plate 22.

[0033] In order to further reduce the complexity of operation, after the pusher is used to push the straw, the spring and the limit plate will apply a backward sliding force to the U-shaped rod 51, so that the U-shaped rod 51 will automatically slide to the side away from the crushing mechanism, that is, the push plate 5 is kept in the engaging groove 52 in the initial state. This can reduce the manual operation of resetting the pusher to further improve efficiency and operational convenience.

[0034] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
