Description

Technical Field

[0001] The invention belongs to the field of loading technology, and in particular relates to a bulk material dust suppression loading system suitable for narrow-mouth containers with crossbeams. Background Art

[0002] The applicant's prior patent application number 2024227192714 is named a pusher for bulk material loading in a chute, and the prior patent application number 2024231094714 is named a flat material loading device for a narrow flat-top carriage. It pushes materials for regular boxes. Originally, L70 special grain vehicles were generally used. The two sides of L70 are curved, so there are fewer areas on both sides where materials cannot reach. Due to the convenience of railway operations, some companies are now gradually changing the boxes used to transport materials into containers, and there are beams on the top of the container structure ( Figure 8 As shown in the figure, the flat material mechanism in the loading mechanism previously designed by the applicant is hindered by the crossbeam during operation. In order to solve this technical problem, the inventor proposed a bulk material dust suppression loading system suitable for narrow-mouth containers with crossbeams. Summary of the invention

[0003] The purpose of the present invention is to design a bulk material dust suppression loading system suitable for a narrow-mouth container with a crossbeam. The present invention improves the push plate so that it can pass through the crossbeam smoothly and also can achieve the purpose of smoothing the material.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is as follows: A bulk material dust suppression loading system suitable for a narrow-mouth container with a cross beam, comprising a feed port and a dust suppression hood, and characterized in that a push-flattening mechanism is installed in the dust suppression hood, and a left and right smoothing mechanism is arranged between the front and rear push-flattening plates of the push-flattening mechanism, and the left and right smoothing mechanisms include an intermediate frame that can move in the dust suppression hood, and material dividers are respectively installed in the left and right directions of the bottom of the intermediate frame, the upper part of the intermediate frame is driven by an upper traction motor, and the lower part of the intermediate frame is driven by a lower traction motor. When the left and right smoothing mechanisms pass through the cross beam, the upper traction motor and the lower traction motor are differentially driven so that the intermediate frame can be tilted to smoothly pass through the cross beam of the box.

[0005] Furthermore, the method is as follows: a track is installed in the dust suppression hood body, and the middle frame moves on the track through the rollers on the top, the middle frame includes an upper vertical frame and a bottom horizontal frame, upper connecting parts extend from both sides of the upper part of the upper vertical frame, lower connecting parts extend from both sides of the lower part of the upper vertical frame, and a divider is installed in the left and right directions of the bottom horizontal frame.

[0006] Furthermore, the divider is formed by continuously hinged four push plates, the divider is fixed to the bottom horizontal frame through the two middle push plates, and the two outermost push plates are based on the hinge structure, and the divider is M-shaped or V-shaped.

[0007] Furthermore, the upper connecting part of the middle frame is connected to the traction rope and driven by the upper traction motor, and the lower connecting part of the middle frame is connected to the traction rope and driven by the lower traction motor.

[0008] Furthermore, the pushing mechanism includes two front and rear pushing plates, which move on the track through rollers on the top. The front and rear pushing plates are connected in series through a traction rope. The upper traction rope of the pushing plate is pulled by a traction motor, and the lower traction rope of the pushing plate is pulled by another traction motor. The two traction motors cooperate to enable the pushing plate to move in the forward and backward directions.

[0009] Furthermore, the traction motors all adopt dual output shafts, and the direction of the traction rope is limited by a number of guide wheels.

[0010] Furthermore, the traction motor and a plurality of guide wheels are mounted on the dust suppression cover through fixing parts.

[0011] The following beneficial effects can be obtained through the above technical solution: The left and right smoothing mechanisms designed in the present invention can solve the problem that the existing push plates are blocked by cross beams, and are suitable for use with narrow-mouthed container vehicles with cross beams, L70, and ordinary open container vehicles. Through the differential speed of two traction motors, the middle frames of the left and right smoothing mechanisms are tilted so that they can pass through the cross beams smoothly. The present invention also designs a unique divider structure, which can be in an M shape or a V shape. When smoothing the material, the divider unfolds into a V shape to smooth the material in the container. By installing such a mechanism in a loading building, dust-free automatic loading of various vehicle models can be completed, reducing investment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The present invention will be further described below by way of examples and drawings: like Figure 1-6 As shown, a bulk material dust suppression loading system suitable for narrow-mouth containers with crossbeams is suitable for narrow-mouth container models with crossbeams, L70, and ordinary open vehicles. Its structure includes a feed port 1 and a dust suppression hood 2. The dust suppression hood 2 is in the shape of a rectangular box. Two tracks 21 are installed in the dust suppression hood 2. A push-flattening mechanism 4 is installed on the track 21. A left and right smoothing mechanism 3 is arranged between the front and rear push-flattening plates of the push-flattening mechanism. The push-flattening mechanism 4 includes a push-flattening plate. Two rollers are installed on the top of the push-flattening plate. The push-flattening plate is installed on the track 21 through the rollers. A traction rope is wound around the output shaft of a double-output shaft type traction motor. The traction rope drives the push-flattening plate to move in the front and rear directions. The two push-flattening plates of the push-flattening mechanism 4 are connected in series through the traction rope. The upper parts of the two push-flattening plates in series are connected A set of traction ropes, and driven by a first double-output shaft type traction motor, the lower parts of the two push plates in series are connected to another set of traction ropes, and driven by a second double-output shaft type traction motor; the left and right leveling mechanism 3 includes an intermediate frame, the intermediate frame includes an upper vertical frame 35 and a bottom horizontal frame 36, the top of the upper vertical frame 35 is equipped with a roller 34, so that the intermediate frame moves on the track 21, and the left and right directions of the bottom horizontal frame 36 are equipped with a distributor 31, the distributor 31 is composed of four push plates connected and hinged, and its hinged part specifically adopts a spring mechanism 39, the distributor 31 is fixed to the bottom horizontal frame 36 through the two middle push plates, and the two outermost push plates are based on the hinged structure. When viewed from a top view, the distributor 31 is in an M shape or a V shape ( Fig. 9 and 10As shown), upper connecting parts 37 are extended from both sides of the upper part of the upper vertical frame 35, and lower connecting parts 38 are extended from both sides of the lower part of the upper vertical frame 35. The upper connecting parts 37 are connected to the traction rope, and the upper traction motor 32 is used to move the upper part of the middle frame. The lower connecting parts 38 are connected to the traction rope, and the traction rope is driven by the lower traction motor 33 to move the lower part of the middle frame. When there is a speed difference between the upper traction motor 32 and the lower traction motor 33, when the speed of the upper traction motor 32 is greater than that of the lower traction motor 33, the middle frame and the distributor are in an inclined state ( Figure 4 as shown).

[0024] The two push plates can remain unchanged. When they reach the edge of the carriage, the push mechanism stops and the M-shaped distributor encounters the material when pushing forward ( Fig.10 As shown), it naturally unfolds into an inverted V shape ( Fig. 9 As shown), it goes deep into the carriage. The left and right leveling mechanisms, when encountering a beam, will retreat first (only when retreating and when there is no material at the front end of the distributor, can the spring mechanism retract the V-shaped distributor structure into an M shape. At this time, the width of the M-shaped distributor is smaller than the width of the container inlet, and the M-shaped distributor can be tilted to exceed the height of the beam, and then move horizontally over the beam. After passing the beam, the M-shaped distributor immediately drops, and then relies on the cooperation of two sets of ropes to go deep into the carriage.

[0025] Figure 7 As shown in the figure, assuming that the material repose angle is 45 degrees, the cross-sectional area of ​​the inaccessible area on both sides is: 2 (left and right areas) * 0.5 * 100cm * 100cm = 1 square meter. The cross-sectional area of ​​the carriage is 2.63 * 2.7m = 7.101 square meters. If it is not horizontally smoothed, the grain loading efficiency is (7.101-1) / 7.101, which is approximately equal to 85.9%. By using the smoothing device of the present invention, it is calculated that the grain loading efficiency can be increased to 97%.

[0026] Take a 12-meter-long container (divided into two sections, each section is 6 meters, each section has 2 crossbeams), load it at one place, after the material enters the carriage and stabilizes, the unloading chute needs to be removed, and then leveled. At this time, if manual leveling or a post-leveling device is used, people or organizations push the material at the inlet Figure 7 The unreachable area in the middle, then move the unloading bucket to unload the material, and then smooth it manually or mechanically, and repeat this process. According to calculations, based on Figure 7 The carriage data shown requires the carriage to be moved repeatedly 5 times to achieve complete leveling and fill the material to Figure 7 The unreachable area shown wastes time and consumes a lot of energy. According to the existing loading data, it takes 30 minutes to load a 12-meter container by manual leveling, and more than 20 minutes for the rear mechanism to level it.

[0027] The loading and smoothing mechanism designed by the present invention not only completely suppresses dust, but also does not need to move the train during the loading process. In addition, the efficiency is greatly improved. The structure of the dust hood is reasonably designed so that the push plate pushes a moderate amount of material each time. Taking a 12-meter-long container (divided into two sections, each section is 6 meters, and each section has 2 crossbeams) as an example, generally a 6-meter carriage is loaded first, and then the second 6-meter carriage is loaded. Assuming that the unloading speed of the chute is fast enough, the push plate moves repeatedly three times to complete the loading of a 6-meter section. Each time the push plate and the smoothing mechanism move no more than 3 meters on one side, the total movement of 3 back and forth is 36 meters. Calculated at a push plate speed of 40 cm / second, it takes 36 / 0.4=90 seconds=1.5 minutes. The process of passing the beam is calculated as 6 seconds. The smoothing mechanism needs to pass through 2 beams back and forth 3 times, a total of 12 beams, a total of 72 seconds, or 1 minute and 12 seconds. Considering the time consumed by other structures, the total loading of a 6-meter carriage can be completed in no more than 3 minutes. The two carriages with a total of 12 meters, plus the time for moving a carriage and unloading time, can be completed in no more than 7 minutes, with an efficiency increase of 77%. At the same time, power consumption is reduced, and there is no need for manual climbing and smoothing, reducing construction risks.

[0028] The specific scenario is that the middle frame approaches the beam. At this time, the leveling divider is lower than the beam, and the beam will block the forward direction of the middle frame and the divider. Therefore, the upper and lower traction motors are controlled to make the upper and lower traction ropes differential, so that the middle frame and the divider are in an inclined state. Since the top of the middle frame is set on the track, in the inclined state, the entire height of the middle frame and the divider becomes smaller, and then the bottom of the divider is higher than the beam. After the divider passes the beam, the upper traction rope does not move, and the lower pull rope moves, so that the middle frame returns to a vertical state.

[0029] In the above embodiment, if there is no front and rear push plates to push and level, at the end of loading, after the middle frame tilts over the cross beam, the divider will be higher than the cross beam in the tilted state, but it will also leave M-shaped materials corresponding to the divider on the upper side of the cross beam. When the cover body is lifted, these materials will flow to the outside of the car. The function of the pushing mechanism is to flatten the M-shaped materials and push them to the far end. Generally speaking, the front and rear pushing mechanisms perform front and rear pushing, and the middle left and right smoothing mechanism 3 performs left and right smoothing.

[0030] In the above embodiment, a fixing part is installed on the outside of the dust suppression hood 2, and several traction motors used in the embodiment are installed on the dust suppression hood 2 through the fixing parts. At the same time, several guide wheels are also installed on the dust suppression hood 2 through the fixing parts. The purpose of the guide wheel is to guide the running path of the traction rope. The setting method and position of the traction motor and the guide wheel can be changed according to the actual device structure, and are not restricted to a specific structure or form.

[0031] The above are all preferred embodiments of the present invention. For ordinary technicians in this technical field, without departing from the principle of the present invention, various equivalent modifications to the present invention belong to the protection scope of the claims attached to this application.
