Description

Technical Field

[0001] The utility model belongs to the technical field of jaw crusher cleaning machinery, and in particular relates to a shovel for safely cleaning blocked materials in a jaw crusher. Background Art

[0002] At present, in order to meet the test particle size requirements specified in the experimental standards during the sample preparation process, laboratories often need to crush the test materials. Jaw crusher is one of the commonly used crushing mechanical equipment. If the moisture content of the material to be tested is high or the material itself has a certain viscosity, due to the particularity of material testing, the material to be tested cannot be dried in advance in most cases. This can easily lead to the material entering the crusher for crushing and then adhering to the inner wall of the crusher, thereby causing blockage. This will not only cause the crusher to be unable to carry out crushing operations normally, but also affect the subsequent testing work.

[0003] The general treatment method for the above situation is to use a shovel to pick the blocked material out of the crusher's cavity. The existing shovel is generally composed of a shovel head and a connecting rod. However, there are certain safety hazards in using the existing shovel in the crushing process. The reason is that during the cleaning process, if the running jaw plate exerts force on the shovel, it will easily cause the shovel to injure the operator who grasps the shovel. Therefore, in order to avoid the above safety accidents, the jaw crusher needs to be shut down before cleaning. Although this method can achieve the purpose of safely cleaning the blockage, the blockage may occur repeatedly during the entire crushing process. Frequent shutdowns for cleaning seriously affect the crusher's operating progress. Therefore, a shovel that can safely clean the blockage while the jaw crusher is running is needed. Utility Model Content

[0004] The purpose of the utility model is to provide a shovel for safely clearing material blockage in a jaw crusher, which can safely clear material blockage when the jaw crusher is running, ensure the personal safety of operators who perform the task of clearing material blockage without stopping the machine, improve the crushing efficiency of the jaw crusher, and effectively avoid the occurrence of material blockage problems during the entire crushing operation.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A shovel for safely clearing blockage in a jaw crusher comprises a shovel head and a connecting rod, and also comprises a cast iron safety ring detachably arranged between the shovel head and the connecting rod, a force sensing alarm system is arranged at one end of the connecting rod close to the cast iron safety ring, and a rubber handle is arranged at the other end.

[0007] A further improvement of the technical solution of the utility model is that the cast iron safety ring is a hollow ring structure, and its two ends can be connected to the shovel head and the connecting rod respectively by means of spiral threads.

[0008] A further improvement of the technical solution of the utility model is that two ends of the cast iron safety ring are respectively sleeved on the shovel head and the connecting rod.

[0009] A further improvement of the technical solution of the utility model is that the force sensing alarm system comprises a force sensor arranged close to the cast iron safety ring and an alarm electrically connected to the force sensor.

[0010] A further improvement of the technical solution of the utility model is that the front end of the shovel head is set to be conical, the rear end thereof is symmetrically provided with barbs, and at least one side of the shovel head is provided with a serrated blade.

[0011] A further improvement of the technical solution of the utility model is that the connecting rod is a telescopic adjustment structure.

[0012] A further improvement of the technical solution of the utility model is that the connecting rod includes a fixed rod and a telescopic rod, one end of the telescopic rod is movably connected to the fixed rod, and the other end is connected to the rubber handle, a force sensing alarm system is arranged at one end of the fixed rod close to the cast iron safety ring, and a locking device is arranged between the fixed rod and the telescopic rod.

[0013] Due to the adoption of the above technical scheme, the technical progress achieved by the utility model is: it can safely clear the blockage when the jaw crusher is running, ensure the personal safety of the operators who perform the blockage clearing task without stopping the machine, improve the crushing efficiency of the jaw crusher, and effectively avoid the occurrence of blockage problems in the entire crushing operation process.

[0014] The utility model adopts a force sensing alarm system arranged at one end of the connecting rod close to the cast iron safety ring. When the operator is cleaning the blockage, it can timely sense the load transmitted to the connecting rod by the shovel head after the jaw plate acts on it. When the load on the connecting rod is too large, the alarm can be used to remind the operator, so that the operator can stop the cleaning operation in time.

[0015] The utility model adopts a cast iron safety ring arranged between the shovel head and the connecting rod. If the operator fails to stop the cleaning operation in time after receiving the alarm that the connecting rod is overloaded, the cast iron safety ring can quickly break due to its fragile feature, so that the connecting rod held by the operator can quickly separate from the shovel head, thereby preventing the operator from being injured.

[0016] The shovel head adopted by the utility model can clean the blocked materials at multiple angles, thus realizing the flexible application of the shovel.

[0017] The rubber handle adopted by the utility model can effectively reduce vibration, so as to prevent the operator from having a strong vibration when holding the handle and affecting the accuracy of the operation. BRIEF DESCRIPTION OF THE DRAWINGS
