Description

Technical Field

[0001] The utility model belongs to the field of tobacco fertilizer processing equipment, and in particular relates to a tobacco fertilizer mixing and weighing device. Background Art

[0002] Fertilizing tobacco requires scientific fertilizer ratios based on the number of acres. Before each fertilization, the required fertilizer raw materials, such as compound fertilizer, potassium sulfate, fermented bean cake, and tobacco, need to be mixed in proportion, and then bagged with a fixed weight for fertilization. In the past, manual mixing and bagging were all done, but manual mixing could not mix the various ingredients evenly, and the bagged fertilizer was heavy, and manual bagging was also inconvenient. Some existing technologies use mixing equipment to stir the fertilizer and then directly discharge it into a fertilizer bag placed on a weighing device, but there are many problems in use. In addition, since the raw materials of tobacco fertilizers are all heavy substances and the amount used is large, the weight of the mixed fertilizers is also heavy. Under the action of gravitational potential energy, when the fertilizers continue to fall into the fertilizer bags, they will cause continuous and multiple impacts on the weighing device, which not only makes the weighing results inaccurate but also easily damages the service life of the weighing device. If the fertilizer bags are not placed directly on the weighing device, the weight of the fertilizers in the fertilizer bags cannot be accurately predicted. The weighing process can only be interrupted many times during the fertilizer loading process, which is cumbersome and affects work efficiency. Utility Model Content

[0003] In order to solve the above problems, the utility model proposes a tobacco fertilizer mixing and weighing device, which includes a feeding mechanism, a stirring mechanism, and a weighing mechanism. The feeding mechanism is connected to the stirring mechanism. A temporary storage bin with a built-in cavity is provided between the weighing mechanism and the stirring mechanism. The temporary storage bin is used to store the fertilizer discharged by the stirring mechanism. The temporary storage bin is connected to a buffer mechanism. The buffer mechanism is used to receive the fertilizer discharged from the temporary storage bin and buffer its kinetic energy. A weighing mechanism is provided below the buffer mechanism, and a fertilizer bag is provided between the buffer mechanism and the weighing mechanism.

[0004] The storage part of the temporary storage bin is used to store the fertilizer mixed by the mixing mechanism. Setting up a temporary storage bin will prevent the weighing process from being affected by the mixing and discharging rhythm. The finished fertilizer discharged from the mixing mechanism is directly discharged into the storage part. If there is no temporary storage bin, it needs to be bagged directly. The bagging time is tight and too much weighing time cannot be left. If the bagging speed is slow, it will affect the subsequent mixing and discharging, and hasty bagging will easily lead to inaccurate weight of the fertilizer. The setting of the temporary storage bin makes the bagging rhythm more flexible, leaving sufficient time for bagging and weighing, which is more conducive to accurate weighing.

[0005] The feeding mechanism, stirring mechanism and weighing mechanism are all existing mechanisms.

[0006] Preferably, the temporary storage warehouse includes a storage part, the storage part is connected to a discharge port, a conveying component is provided between the storage part and the discharge port, the discharge port is provided with a valve, and the valve and the conveying component are connected to a control component.

[0007] When the valve is closed, the control component controls the conveying component to stop running. The conveying component can be a conveyor belt, or a feeding auger or other structure that can achieve the purpose of feeding. The control component can be a PLC controller, etc. It can be achieved here by using existing control components, and will not be elaborated.

[0008] The valve can be closed manually according to the weight displayed by the weighing mechanism, or the weighing mechanism can be connected to the control component. When the fertilizer in the fertilizer bag reaches the set weight, the control component controls the valve to close and the conveying component to stop conveying.

[0009] Preferably, the buffer mechanism includes a sliding cavity with an inclined inner wall, the lower end of the sliding cavity is connected to a sliding platform, one end of the sliding platform is connected to the sliding cavity, and the other end is connected to a buffer strip; when the fertilizer slides in the inner wall of the sliding cavity, the falling speed will slow down under the action of friction, and its kinetic energy will be further reduced after falling into the sliding platform. At this time, when it falls into the fertilizer bag through the buffer strip, the impact on the weighing mechanism will be reduced.

[0010] Preferably, the sliding platform is provided with a conveyor belt, which needs to be transported slowly toward the buffer bar. The buffer belt is provided to prevent the residual fertilizer from falling smoothly into the fertilizer bag due to insufficient kinetic energy when there is too little fertilizer, thereby preventing the fertilizer from accumulating on the sliding platform.

[0011] Furthermore, it also includes a bagging mechanism, which includes a supporting assembly, and the supporting assembly includes a fixing part, which is connected to the opening of the fertilizer bag and is close to the buffer bar and located below it. The fixing part is connected to a supporting part that is inclined from the opening of the fertilizer bag to the bottom of the fertilizer bag, and the fertilizer bag is supported by the supporting part.

[0012] The supporting assembly is used to support the fertilizer in the fertilizer bag. When the fertilizer falls into the fertilizer bag from the buffer bar, it will first impact the supporting part across the fertilizer bag. Since the supporting part and the buffer bar are close to each other, the impact force is extremely small. Then, under the action of gravity, the fertilizer slowly slides to the bottom of the fertilizer bag along the inclined supporting part. In this process, the sliding process consumes the kinetic energy of the fertilizer. Compared with not setting up the supporting assembly and the fertilizer falling into the fertilizer bag from the buffer bar, the impact of the fertilizer on the weighing mechanism is further reduced, thereby increasing the service life of the weighing mechanism.

[0013] Preferably, the bagging mechanism also includes a conversion mechanism, which includes a transport frame connected to a plurality of supporting components. The conversion mechanism is provided with a rotating component, which drives the conversion mechanism to rotate so that the plurality of supporting components are alternately located between the buffer mechanism and the weighing mechanism.

[0014] A conversion mechanism is provided to drive the transport frame to rotate through the rotating assembly so that the supporting assembly is filled with fertilizer and transported away while the empty supporting assembly continues to be loaded with fertilizer.

[0015] A connecting piece is provided between the supporting assembly and the transport frame, and the connecting piece is used for detachably connecting the supporting assembly and the transport frame.

[0016] When weighing, remove the supporting assembly and place it in the weighing mechanism to ensure that the supporting assembly is not affected by the transport frame and maintain the accuracy of weighing. After weighing, install the supporting assembly on the transport frame for transportation.

[0017] Preferably, the connecting member includes a hook and a hanging ring, and the supporting assembly and the transport rack are detachably connected via the hook and the hanging ring.

[0018] The connecting part includes a telescopic rod arranged on the transport frame, and the supporting component is provided with a hole that matches the telescopic rod. The telescopic rod can be an electric telescopic rod or a hydraulic telescopic rod, and the position of the hole can also be set in multiple ways, such as: when the supporting component is placed on the weighing mechanism without load, a first hole is provided at the position where the telescopic rod and the supporting component are opposite to each other; when the supporting component is placed on the weighing mechanism with full load, a second hole is provided at the position where the telescopic rod and the supporting component are opposite to each other. The multiple holes are provided to adapt to the weighing component that produces up and down displacement during part of the weighing process, thereby improving the applicability of the weighing component.

[0019] A universal wheel is provided at the bottom of the supporting assembly, and the weighing mechanism is provided with a fixing groove for fixing the universal wheel; the universal wheel is used to transport fertilizer after the supporting assembly is disassembled, and the fixing groove is used to fix the universal wheel to prevent the supporting assembly from moving during the loading and weighing process.

[0020] The utility model is beneficial in that:

[0021] (1) Setting up a temporary storage warehouse so that the weighing process is not affected by the rhythm of stirring and discharging, the bagging rhythm is more flexible, and the time for bagging and weighing is more sufficient, which is more conducive to accurate weighing.

[0022] (2) A buffer mechanism is provided. The sliding cavity and the sliding platform cooperate to easily remove the impact force of the falling fertilizer, making the impact force of the fertilizer on the weighing mechanism smaller, which is beneficial to improving the service life of the weighing mechanism.

[0023] (3) A supporting assembly is provided to make the movement of the fertilizer falling into the fertilizer bag more gentle, further reducing the impact on the weighing mechanism.

[0024] (4) A conversion mechanism is provided to allow multiple supporting assemblies to be loaded with fertilizers in turn, thereby improving bagging efficiency. The supporting assemblies and the rotation mechanism are detachably connected, and the rotation mechanism will not affect weighing. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Example 1, as Figure 1 、 2 As shown, a tobacco fertilizer mixing and weighing device includes a feeding mechanism 1, a stirring mechanism 2, and a weighing mechanism 5. The feeding mechanism 1 is connected to the stirring mechanism 2. A temporary storage bin 3 with a built-in cavity is provided between the weighing mechanism 5 and the stirring mechanism 2. The temporary storage bin 3 is used to store the fertilizer discharged by the stirring mechanism 2. The temporary storage bin 3 is connected to a buffer mechanism 4.

A fertilizer bag is provided between the buffer mechanism 4 and the weighing mechanism 5.

[0039] The feeding mechanism 1, the stirring mechanism 2 and the weighing mechanism 5 are all existing mechanisms.

[0040] The temporary storage warehouse 3 includes a storage part, the storage part is connected to the discharge port, and a conveying component 31 (such as Figure 2 As shown), the discharge port is provided with a valve (not shown in the figure), and the valve and the conveying component 31 are connected with a control component.

[0044] When the fertilizer slides on the inner wall of the sliding cavity 41 , the falling speed will be slowed down by the friction force. After falling onto the sliding platform 42 , its kinetic energy will be further reduced. At this time, when it falls into the fertilizer bag through the buffer bar 43 , the impact on the weighing mechanism 5 will be reduced.

[0045] Preferably, the sliding platform 42 is provided with a conveyor belt (not shown in the figure), which needs to be transported slowly toward the buffer bar 43.

When the fertilizer falls into the fertilizer bag from the buffer bar 43, it will first impact the supporting portion 611 across the fertilizer bag. Since the supporting portion 611 is close to the buffer bar 43, the impact force is extremely small. Then, under the action of gravity, the fertilizer slowly slides to the bottom of the fertilizer bag along the inclined supporting portion 611. In this process, the sliding process consumes the kinetic energy of the fertilizer. Compared with not setting the supporting assembly 61 and the fertilizer falling into the fertilizer bag from the buffer bar 43, the impact of the fertilizer on the weighing mechanism 5 is further reduced.
