DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 5 As shown, the utility model provides a chemical material screening machine, including a screening bin 1, the inner cavity of the screening bin 1 is fixedly connected with a mounting plate 2, the top of the mounting plate 2 is fixedly connected with a spring assembly 3, the top of the spring assembly 3 is fixedly connected with a screening plate 4, the inner cavity of the screening bin 1 is movably connected with a knocking rod 6, the top of the screening plate 4 is fixedly connected with a material blocking plate 9, and the outer side of the screening bin 1 is fixedly connected with a supporting foot 10;

[0022] The material flows on the surface of the screening plate 4 and is screened by the screening plate 4. The material is then blocked by the material blocking plate 9, so that the material can stay on the top of the screening plate 4 for a long time. The knocking rod 6 is then driven to rotate by the transmission assembly 14, and the protrusion of the knocking rod 6 contacts the screening plate 4. The screening plate 4 is vibrated by the elasticity of the spring assembly 3, so as to prevent the material from clogging the sieve holes of the screening plate 4. The accuracy of material screening is improved by the material blocking plate 9, and clogging is avoided by the vibration of the screening plate 4, thereby improving the screening efficiency.

[0023] Among them, the top of the screening bin 1 is fixedly connected with a feed pipe 11, the top of the feed pipe 11 is fixedly connected with a conical tube 5, the rear side of the feed pipe 11 is fixedly connected with a servo motor 12, the output shaft of the servo motor 12 is fixedly sleeved with a spacer rod 13, and the spacer rod 13 is provided with a transmission assembly 14;

[0024] By inputting the material from the feed pipe 11 and then starting the servo motor 12 to drive the spacer rod 13 to rotate, the material can be diverted through the rotation of the spacer rod 13, so that the material enters the inner cavity of the screening bin 1 in batches, avoiding large quantities of material from entering the inner cavity of the screening bin 1 too quickly, thereby causing material stacking, and further improving the material screening efficiency.

[0025] The spring assembly 3 is composed of a damping telescopic rod and a spring, and the damping telescopic rod is located at the center of the spring cavity;

[0026] Through the setting of the spring, the screening plate 4 can vibrate after being struck by the striking rod 6, and then the screening plate 4 is positioned and guided by the damping telescopic rod, thereby avoiding the screening plate 4 from deflecting during vibration, thereby improving the stability of the screening plate 4 during use.

[0027] There are a plurality of baffle plates 9, which are divided into groups of three or two and are staggeredly installed on the top of the screening plate 4;

[0028] By staggered installation of multiple baffle plates 9, materials can contact with the baffle plates 9 and be blocked by the baffle plates 9 when flowing at the top of the screening plate 4, thereby avoiding that only part of the material contacts with the baffle plates 9, further reducing the flow speed of the material and improving the accuracy of screening.

[0029] The bottom end of the screening bin 1 is fixedly connected to a material collecting bin 7, and the bottom end of the material collecting bin 7 is fixedly connected to a material discharging pipe 8, and the material collecting bin 7 is a conical hollow body;

[0030] By setting up the collecting bin 7, smaller materials can pass through the sieve holes of the screening plate 4 and be discharged into the inner cavity of the collecting bin 7, and then be discharged through the discharge pipe 8 for collection. In addition, the collecting bin 7 is a conical hollow body, so that the materials can be concentratedly guided through the collecting bin 7, so that the materials can be discharged from the discharge pipe 8, thereby improving the convenience of collection.

[0031] The transmission assembly 14 is composed of two anti-skid transmission shafts and a transmission belt, and the two anti-skid transmission shafts are fixedly connected to the knocking rod 6 and the spacer rod 13 respectively;

[0032] By setting the anti-slip transmission shaft, the spacer rod 13 drives one of the anti-slip transmission shafts to rotate, then drives the transmission belt to operate, and then drives the anti-slip transmission shaft fixedly connected to the knocking rod 6 to rotate, thereby achieving the goal of driving the knocking rod 6 to rotate while the spacer rod 13 divides the materials into batches.

[0033] The top of the screening bin 1 is fixedly connected with a support ring 15, and the material separation rod 13 is movably sleeved in the inner cavity of the support ring 15;

[0034] By providing the support ring 15 , the support ring 15 can support the spacer rod 13 , thereby improving the stability of the spacer rod 13 during operation, and also enabling the spacer rod 13 to be connected to the transmission assembly 14 .

[0035] The working principle and use process of the utility model are as follows: the material is added from the conical tube 5 into the inner cavity of the feed tube 11, and then the servo motor 12 is started to drive the material separation rod 13 to rotate, so that the material enters the inner cavity of the screening bin 1 from the feed tube 11 in batches, and the material falls on the top of the screening plate 4 and moves along the top of the screening plate 4, and is blocked by the material blocking plate 9 to reduce the speed of the material flow;

[0036] Then, the transmission assembly 14 is driven to operate through the spacer rod 13, and the operation of the transmission assembly 14 drives the knocking rod 6 to rotate. When the knocking rod 6 rotates, the raised portion of the knocking rod 6 contacts the screening plate 4, thereby knocking the screening plate 4. Then, through the retractability and elasticity of the spring assembly 3, the screening plate 4 is vibrated, thereby preventing the screen holes of the screening plate 4 from being blocked. Larger materials are discharged from the left side of the screening bin 1, and smaller materials fall into the inner cavity of the collecting bin 7, and are then discharged through the discharge pipe 8.

[0037] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
