[0023] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0024] The unloading device and mixing station of this utility model are described below with reference to the accompanying drawings.

[0025] like Figures 1 to 2 As shown, this utility model provides a unloading device, wherein the unloading device includes: 100 unloading hopper components; An adjusting cylinder assembly 200 is sleeved on the lower end of the unloading hopper assembly 100, and an adjusting seat 230 is provided on the outer peripheral side of the adjusting cylinder assembly 200; The adjustment assembly includes an adjustment rod 300 and a first stop 400. The adjustment rod 300 is vertically arranged, with its upper end on the discharge hopper assembly 100 and its lower end passing through the adjustment seat 230. The first stop 400 is sleeved on the lower side of the adjustment seat 230. The first stop 400 abuts against the adjustment seat 230 and is radially provided with a first fastener 410. The first fastener 410 is used to abut against the adjustment rod 300 when tightened.

[0026] When using the above-mentioned unloading device, since it includes an unloading hopper assembly 100, an adjusting cylinder assembly 200, and an adjusting component, the adjusting cylinder assembly 200 is sleeved on the lower end of the unloading hopper assembly 100. The lower end of the adjusting rod 300 installed on the unloading hopper assembly 100 passes through the adjusting seat 230 on the adjusting cylinder assembly 200. A first stop 400 is sleeved on the lower side of the adjusting seat 230 of the adjusting rod 300. The first stop 400 abuts against the adjusting seat 230 and is radially inserted by a first fastener 410. When the first fastener is loosened... With firmware 410, the adjusting seat 230 and the first stop 400 can be moved along the height direction of the adjusting rod 300 to adjust the height of the adjusting cylinder assembly 200. After the adjustment is in place, the height of the adjusting seat 230 on the adjusting rod 300 can be locked by tightening the first fastener 410, thereby realizing the adjustment of the unloading height of the unloading device to suit different models of mixer trucks. Then, the mixer truck does not need to adjust its posture when receiving materials, saving time and effort and avoiding the phenomenon of poor docking.

[0027] Specifically, the upper end of the unloading hopper assembly 100 can be used to allow finished concrete produced by the mixing plant to enter, and the lower end of the regulating cylinder assembly 200 can be connected to the feed hopper of the mixer truck so that the finished concrete can smoothly enter the mixer truck through the unloading device.

[0028] In one embodiment of this utility model, the adjusting seat 230 is provided with a bearing 600 through which the adjusting rod 300 can pass. The addition of the bearing 600 makes the movement of the adjusting seat 230 on the adjusting rod 300 smoother, facilitating adjustment and preventing wobbling. Specifically, the bearing 600 can be an integral structure with the adjusting seat 230 or a separate structure. Furthermore, the bearing 600 extends beyond the adjusting seat 230, ensuring a greater length for further adjustment. To reduce the weight of the adjusting cylinder assembly 200, the adjusting seat 230 can be a plate. The length of the bearing 600 will be significantly greater than the thickness of the plate, inevitably resulting in the bearing 600 extending beyond the adjusting seat 230. It should be noted that when a bearing component 600 is added, the first stop 400 is configured to abut against the adjusting seat 230 or the bearing component 600. This depends on whether the lower end of the bearing component 600 extends out of the adjusting seat 230. If the lower end of the bearing component 600 extends out of the adjusting seat 230, the first stop 400 is configured to abut against the lower end face of the bearing component 600. If the lower end of the bearing component 600 does not extend out of the adjusting seat 230, the first stop 400 is configured to abut against the lower end face of the adjusting seat 230.

[0029] In one embodiment of this utility model, the adjusting seat 230 is provided with a bearing through hole, and the bearing component 600 includes a flange 610 and a bearing body 620 connected in sequence. The flange 610 is located on the lower side of the adjusting seat 230 and abuts against the adjusting seat 230. The bearing body 620 passes through the bearing through hole and extends upward from the adjusting seat 230. The first stop member 400 abuts against the end face of the flange 610 away from the bearing body 620. That is, the bearing component 600 and the adjusting seat 230 are set as separate structures. This arrangement facilitates manufacturing and places the flange 610 below the adjusting seat 230. The first stop 400 abuts against the lower end face of the flange 610. The first stop 400, flange 610, and adjusting seat 230 are stacked sequentially, allowing the first stop 400 to support the adjusting seat 230 while simultaneously pressing the flange 610 against it, ensuring the stability of the bearing 600 between the adjusting seat 230 and the adjusting rod 300. Specifically, the bearing 600 can be an elliptical flange linear bearing. Furthermore, the adjusting assembly includes a second stop 500, which is sleeved on the adjusting rod 300 and abuts against the end face of the bearing body 620 away from the flange 610. A second fastener 510 is radially inserted through the second stop 500, which is used to tighten against the adjusting rod 300 when tightened. The second stop 500 is located on the upper side of the bearing body 620 and abuts against the upper end face of the bearing body 620. The addition of the second stop 500 allows for clamping and positioning of the upper and lower ends of the bearing 600 on the adjusting rod 300, further ensuring the installation stability of the bearing 600. However, this invention is not limited to this; a single first stop 400 is also acceptable.

[0030] In one embodiment of this utility model, both the first stop 400 and the second stop 500 are provided with two fastening holes, both of which can be used for corresponding fasteners to pass through. The included angle between the two fastening holes on the same stop in the circumferential direction is set to 90°. That is, both the first stop 400 and the second stop 500 can be tightly connected to the adjusting rod 300 from different radial directions. Specifically, the first fastener 410 and the second fastener 510 can be threaded fasteners, and both fastening holes on the same stop can be threaded holes. When the threaded fastener is tightened onto the corresponding stop, the head of the threaded fastener abuts against the outer side of the stop, and the end of the threaded fastener away from the head abuts against the adjusting rod 300, so that the side of the adjusting rod 300 facing away from the threaded fastener presses against the stop. Of course, this utility model is not limited to this; the fastening holes on the same stop can also be one, three, or four, etc., and the three or four fastening holes can be evenly spaced in the circumferential direction.

[0031] In one embodiment of this utility model, the adjusting rod 300 is provided with scale markings 310 along the height direction. The addition of scale markings 310 allows the adjustment action to be completed in one step and ensures adjustment accuracy. Specifically, the corresponding scale marking 310 can be determined in advance according to the model of the mixer truck, and then the adjusting seat can be adjusted to correspond to this scale marking 310. It should be particularly noted that when a bearing component 600 is added and its upper end extends beyond the adjusting seat 230, the upper end of the bearing component 600 can be used as an alignment structure; that is, when the adjustment is complete, the upper end of the bearing component 600 is aligned with the determined scale marking 310. Specifically, as shown... Figures 2 to 5 As shown, the scale markings 310 on the adjusting rod 300 provide a vertical adjustment stroke of ±200mm, and are divided into 1mm increments. The scale markings 310 are formed by laser engraving. The adjusting rod 300 is made of 40Cr alloy steel and has a hard chrome plated surface.

[0032] In one embodiment of this utility model, the adjusting rod 300 has connecting holes at both its upper and lower ends. These connecting holes can be threaded holes or rivet holes. The adjusting assembly also includes a third fastener 320, a fourth fastener 330, and a limiting end plate 340. The third fastener 320 passes through the unloading hopper assembly 100 and extends into the connecting hole at the upper end of the adjusting rod 300 for fastening. When the connecting hole is a threaded hole, the third fastener 320 can be a threaded fastener; when the connecting hole is a rivet hole, the third fastener 320 can be a rivet. That is, the upper end of the adjusting rod 300 can be detached and installed on the unloading hopper assembly 100 via the third fastener 320. Simultaneously, the fourth fastener 330 passes through the limiting end plate 340 and extends into the connecting hole at the lower end of the adjusting rod 300 for fastening. That is, the limiting end plate 340 can be detached and installed on the adjusting rod 300 via the fourth fastener 330. The addition of the limiting end plate 340 serves as a lower limit, specifically as follows: Figure 3 As shown, when the adjusting cylinder assembly 200 is adjusted to the lower limit, the first stop 400 abuts against the limit end plate 340. Simultaneously, the adjusting rod 300 can be replaced by disassembling the third fastener 320 and the fourth fastener 330.

[0033] In one embodiment of this utility model, there are two adjusting seats 230 and two adjusting components. The two adjusting seats 230 are respectively disposed on opposite sides of the adjusting cylinder assembly 200, and the two adjusting components are respectively arranged in a one-to-one correspondence with the two adjusting seats 230, thereby ensuring the stability of the adjusting cylinder assembly 200 installed on the unloading hopper assembly 100. Of course, this utility model is not limited to this, and the number of adjusting seats 230 and adjusting components can be set according to specific needs.

[0034] In one embodiment of the present invention, a fixing seat 130 is provided on the outer periphery of the unloading hopper assembly 100. The fixing seat 130 includes a fixing plate portion 131 that extends laterally and a fixing bending plate portion 132 that is bent from one end of the fixing plate portion 131. The fixing bending plate portion 132 is attached to the outer periphery of the unloading hopper assembly 100, and the upper end of the adjusting rod 300 is mounted on the fixing plate portion 131. By adding the fixed bending plate portion 132 to the fixed seat 130, it is easier to mount the fixed seat 130 onto the unloading hopper assembly 100. Specifically, the fixed bending plate portion 132 can be welded onto the unloading hopper body 110 of the unloading hopper assembly 100. To ensure it fits snugly against the outer periphery of the unloading hopper body 110, when the fixed bending plate portion 132 is bent upwards from one end of the fixed flat plate portion 131, the included angle between the fixed bending plate portion 132 and the fixed flat plate portion 131 is acute; when the fixed bending plate portion 132 is bent downwards from one end of the fixed flat plate portion 131, the included angle between the fixed bending plate portion 132 and the fixed flat plate portion 131 is obtuse. A reinforcing plate portion can be provided between the fixed bending plate portion 132 and the fixed flat plate portion 131. Furthermore, the fixed flat plate portion 131 has a fastener through hole for the third fastener 320 to pass through, such as... Figure 5 As shown, when the adjusting cylinder assembly 200 is adjusted to the upper limit, the second stop 500 abuts against the fixed plate portion 131.

[0035] In one embodiment of the present invention, the adjusting seat 230 includes an adjusting plate portion 231 that extends laterally and an adjusting bent plate portion 232 that is bent from one end of the adjusting plate portion 231. The adjusting bent plate portion 232 is attached to the outer periphery of the adjusting cylinder assembly 200, and the lower end of the adjusting rod 300 passes through the adjusting plate portion 231. The adjusting rod 300 is fitted with a first stop member 400 on the lower side of the adjusting plate portion 231. By adding the adjusting bending plate portion 232, the adjusting seat 230 can be easily mounted on the adjusting cylinder assembly 200. Specifically, the adjusting bending plate portion 232 can be welded onto the feed hopper 210 of the adjusting cylinder assembly 200. To ensure it fits snugly against the outer periphery of the feed hopper 210, when the adjusting bending plate portion 232 is bent downwards from one end of the adjusting plate portion 231, the included angle between the adjusting bending plate portion 232 and the adjusting plate portion 231 is an obtuse angle. A reinforcing plate portion can be provided between the adjusting bending plate portion 232 and the adjusting plate portion 231. Furthermore, a bearing through hole is provided on the adjusting plate portion 231.

[0036] In one embodiment of this utility model, the unloading hopper assembly 100 includes an unloading hopper body 110 and a straight cylindrical body 120. The upper end of the straight cylindrical body 120 is connected to the lower end of the unloading hopper body 110 via bolt disassembly. The upper end of the adjusting cylinder assembly 200 is provided with a fitting port for the straight cylindrical body 120 to extend into. The upper end of the adjusting rod 300 is mounted on the unloading hopper body 110. That is, by adding the straight cylindrical body 120, the upper end of the adjusting cylinder assembly 200 can be easily adjusted in height on the outside of the straight cylindrical body 120, thereby adjusting the unloading height of the unloading device by adjusting the exposed height of the straight cylindrical body 120. Of course, this utility model is not limited to this; the adjusting cylinder assembly 200 can also be configured to be directly height-adjustable on the outside of the unloading hopper body 110. However, this would inevitably result in an excessively large size for the adjusting cylinder assembly 200, making adjustment more difficult. The upper end of the straight cylindrical body 120 is connected to the lower end of the unloading hopper body 110. That is, the radial dimension of the straight cylindrical body 120 along its entire height direction is the same as that of the lower end of the unloading hopper assembly 100. The radial dimension of the adjusting cylinder assembly 200, which is sleeved on the outside of the straight cylindrical body 120, is set to be greater than that of the lower end of the unloading hopper assembly 100. Specifically, both the unloading hopper body 110 and the straight cylindrical body 120 can be made of Q345B steel plate.

[0037] In one embodiment of this utility model, the adjusting cylinder assembly 200 includes a hopper 210 with its large end opening facing upwards. The upper part of the hopper 210 has a fitting opening that allows the straight cylinder 120 to extend into the hopper 210. An adjusting seat 230 is disposed on the outer peripheral side of the hopper 210. By setting the hopper 210, when the hopper 210 is involved in material feeding, on the one hand, the feeding space is increased, and on the other hand, the inclined wall of the hopper 210 further controls the feeding speed.

[0038] In one embodiment of this utility model, the radial dimension of the small-end opening of the hopper 210 facing downwards is larger than the radial dimension of the cylindrical body 120. This ensures that when the lower end of the cylindrical body 120 is adjusted to be close to the small-end opening, the hopper 210 will not obstruct material flow. Simultaneously, a sealing ring plate 211 is provided on the inner circumference of the hopper 210 near the large-end opening. The sealing ring plate 211 forms a fitting opening, and the radial dimension of the fitting opening is consistent with the radial dimension of the cylindrical body 120. The addition of the sealing ring plate 211 serves a sealing function to prevent concrete from splashing to the outside. However, this utility model is not limited to this; the sealing ring plate 211 may be omitted, and the upper opening of the hopper 210 can be directly set as a fitting opening.

[0039] In one embodiment of this utility model, the regulating cylinder assembly 200 further includes a flexible cylinder 220, the upper end of which is detachably installed to the lower end of the hopper 210 via a clamp 221. The addition of the flexible cylinder 220 facilitates adaptation to different sized feed inlets on the mixer truck. Specifically, the flexible cylinder 220 can be made of rubber or other suitable soft materials.

[0040] Furthermore, this utility model also provides a mixing plant, wherein the mixing plant includes the unloading device according to the above-described embodiments. Since the mixing plant adopts all the technical solutions of the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated further here.
