[0002] The compression method of mobile stations on the market today, especially circular mobile stations, is mainly single compression. The following problems exist during the operation process: the garbage compaction rate is not high. The garbage needs to enter the box to fill the lower part of the box before the compression effect occurs. The compaction force on the garbage is insufficient, the garbage compaction density is low, and the garbage transfer efficiency is low; there is no water reduction process before the garbage enters the box, the garbage has a high water content, and there is dripping during the transfer process. In order to solve the above problems, some manufacturers have proposed a mechanism to set a baffle at the front of the garbage box to pre-compress the garbage, but the existing solution only proposes a pre-compression structure and does not involve relevant control methods; the mobile station equipped with a pre-compression mechanism has an additional compression process, which reduces the processing efficiency of the mobile station, and will cause the front-end collection vehicles to queue up during the peak period of garbage processing.

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0039] It should be noted that in the description of the present invention, the directions or positional relationships indicated by the terms "front", "rear", "left", "right", "up", "down", "inside", "outside", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention rather than requiring the present invention to be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. The terms "front", "rear", "left", "right", "up", and "down" used in the description of the present invention refer to the directions in the accompanying drawings, and the terms "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0040] like Figure 2 and Figure 3 As shown, the present invention provides an optional secondary compression method, including judging whether the working condition of the mobile station meets the conditions for secondary compression; when the working condition of the mobile station meets the conditions for secondary compression, the pre-compression mode is selected. Wherein, in the pre-compression mode, the gate on the left side of the box 5 is closed, and the push head pushes to squeeze the garbage between the push head and the gate; the pressure of the push head is detected, and when the pressure of the push head reaches the set threshold, it indicates that the preliminary compression of the garbage has been completed. The push head retreats, and after releasing the force of the push head acting on the gate, the gate is opened, and the push head pushes the garbage into the box 5 to complete the garbage collection in the pre-compression mode. When the working condition of the mobile station does not meet the conditions for secondary compression, the direct compression mode is selected. Wherein, in the direct compression mode, the gate of the box 5 is opened, and the push head pushes the garbage into the box 5 to complete the garbage collection.

[0041] In this embodiment, there are two methods for determining whether the working condition of the mobile station satisfies the conditions for secondary compression. The first method is: Step 1, monitoring the number of input electrical signals of the hopper raising button 10 and the hopper lowering button 11 of the remote control within a predetermined time. The hopper raising button 10 and the hopper lowering button 11 of the remote control are used to control the operation of the lifting mechanism 1. Step 2, calculating the lifting frequency of the lifting mechanism 1 according to the number of input electrical signals. One lifting frequency includes one input electrical signal of the hopper raising button 10 and one input electrical signal of the hopper lowering button 11. If the lifting frequency of the lifting mechanism 1 is greater than a preset lifting frequency threshold, the conditions for secondary compression are not met; if the lifting frequency of the lifting mechanism 1 is not greater than the preset lifting frequency threshold, the conditions for secondary compression are met.

[0042] The second method is as follows: Step 1, monitoring the number of electrical signals of the displacement sensor 1-1 being powered on and off within a predetermined time; wherein the displacement sensor 1-1 is installed on the lifting mechanism 1; Step 2, calculating the lifting frequency of the lifting mechanism 1 according to the number of electrical signals of the displacement sensor 1-1 being powered on and off. If the lifting frequency of the lifting mechanism 1 is greater than a preset lifting frequency threshold, the condition for secondary compression is not met; if the lifting frequency of the lifting mechanism 1 is not greater than the preset lifting frequency threshold, the condition for secondary compression is met.

[0043] The optional secondary compression method provided by the present invention indirectly judges the working condition of the mobile station through the lifting frequency of the hopper on the lifting mechanism 1. When the collected signal frequency is greater than the threshold value set by the system, it proves that the lifting mechanism 1 is lifting frequently at this time, which can indirectly prove that the mobile station is in the peak period of garbage disposal at this time, so the compression mode selection module selects the direct compression mode; when the collected signal frequency is less than the threshold value set by the system, it proves that the lifting mechanism 1 is not lifting frequently at this time, which can indirectly prove that the mobile station is in the trough period of garbage disposal at this time, so the compression mode selection module selects the pre-compression module.

[0044] like Figure 1 As shown, the circular mobile station with a pre-pressing mechanism provided by the present invention comprises a lifting mechanism 1, a hydraulic-electric control system 2, a push head assembly 3, a gate mechanism 4, a box 5 and a rear door 6 from left to right. The rear door 6 is openably installed at the right end of the box 5, and the gate mechanism 4 is connected to the left end of the box 5. The gate mechanism 4 includes a gate and a gate cylinder 4-1. The gate cylinder 4-1 controls the movement of the gate, and the gate 4 is used to open and close the box 5. The push head assembly 3 includes a push head cylinder 3-1 and a push head, and the movement of the push head cylinder 3-1 drives the push head to move. When the gate on the left side of the box 5 is opened, the push head moves to transport the garbage on the push head to the hopper on the lifting mechanism 1 and pushes it into the box 5. When the gate on the left side of the box 5 is closed, the push head moves to transport the garbage on the push head to the hopper on the lifting mechanism 1 and pushes it to the gate and squeezes it with the gate.

[0045] The hydraulic-electric control system 2 involves three modules, including a signal acquisition module, a working condition determination module, and a compression mode selection module. The compression mode selection module includes a direct compression module and a pre-compression module. Figure 3 The direct compression module mainly controls the gate 4 to open through the hydraulic-electric control system, and the push head 3 is continuously pushed out and retracted to push the garbage in the compression chamber into the box body 5. When the garbage in the box body 5 reaches a certain amount, the push head 3, the box body 5 and the rear door 6 form a closed compression space to squeeze the garbage, which is a primary compression; the pre-compression module mainly controls the gate 4 to close through the hydraulic-electric control system, and the push head 3 is pushed out. The push head 3, the gate 4 and the side wall of the compression chamber form a temporarily closed compression space to compress the garbage once, which is a pre-compression. Then the push head 3 retreats for 2 seconds to release the pressure on the gate. The gate is opened, the push head is pushed out, and the garbage is pushed into the box body to form a secondary compression.

[0046] The hydraulic principle diagram of the preloading mode is as follows: Figure 4 As shown, the hydraulic-electric control system includes an unloading solenoid valve, a push head solenoid reversing valve, a push head speed switching solenoid valve, a hopper solenoid reversing valve, a gate solenoid reversing valve, a one-way throttle valve and a two-way hydraulic control one-way valve. The push head solenoid reversing valve, the push head speed switching valve and the push head oil cylinder are connected to control the operation of the push head oil cylinder 3-1. The hopper solenoid reversing valve is connected to the flip oil cylinder to control the operation of the hopper, that is, to control the lifting mechanism to drive the hopper to work. The gate solenoid reversing valve is connected to the gate oil cylinder 4-1 to control the operation of the gate oil cylinder 4-1.

[0047] The hopper electromagnetic reversing valve and gate electromagnetic reversing valve are both three-position four-way electromagnetic reversing valves. When each three-position four-way electromagnetic reversing valve is in the middle position, the oil port P is closed, and the oil ports A, B and T are connected; when each three-position four-way electromagnetic reversing valve is in the left position, the oil port P is connected to the oil port B, and the oil port A is connected to the oil port T; when each three-position four-way electromagnetic reversing valve is in the right position, the oil port P is connected to the oil port A, and the oil port B is connected to the oil port T.

[0048] The unloading solenoid valve and the push head solenoid reversing valve are both two-position four-way solenoid reversing valves. When each two-position four-way solenoid reversing valve is in the left position, the oil port P is connected with the oil port B, and the oil port A is connected with the oil port T; when each two-position four-way solenoid reversing valve is in the right position, the oil port P is connected with the oil port A, and the oil port B is connected with the oil port T.

[0049] The push head speed switching solenoid valve is a two-position four-way solenoid valve. When it is in the left position, oil port P is connected to oil port B, and oil port A and oil port T are closed; when it is in the right position, oil port P is connected to oil port A, and oil port B and oil port T are closed. In the hydraulic control system, both the hopper and the gate oil circuit are equipped with a two-way hydraulically controlled one-way valve and a one-way throttle valve.

[0050] In this embodiment, a remote controller is also included, on which an emergency stop button 7 is provided (the emergency stop button can be used for emergency shutdown. After rotating and releasing the emergency stop button, other operations can be performed), a full load indicator light 8 (the full load indicator light is used to determine whether the trash bin is fully loaded. If the light is on, it indicates that the trash bin is fully loaded), a start button 9 (pressing the start button pushes the head to perform a compression cycle), a hopper raising button 10, and a hopper lowering button 11. The remote controller is connected to the hydraulic control system signal. The hopper raising button 10 and the hopper lowering button 11 are used to control the lifting and lowering of the hopper on the lifting mechanism 1.

[0051] The present invention provides a selectable secondary compression system, including a working condition judgment module and a compression mode selection module. Working condition judgment module: used to judge whether the working condition of the mobile station meets the conditions for secondary compression; first compression mode selection module: used to select the pre-compression mode when the working condition of the mobile station meets the conditions for secondary compression; wherein, in the pre-compression mode, the gate of the box is closed, and the push head pushes to squeeze the product between the push head and the gate; the pressure of the push head is detected, and when the pressure of the push head reaches the set threshold, the push head retreats, opens the gate, and the push head pushes to push the product into the box; second compression mode selection module: used to select the direct compression mode when the working condition of the mobile station does not meet the conditions for secondary compression; wherein, in the direct compression mode, the gate of the box is opened, and the push head pushes the product into the box.
