[0002] Self-loading garbage trucks are one of the main garbage collection and transportation equipment in my country. They can realize functions such as loading garbage bins, compressing garbage, and unloading by tipping the box.

In the actual operation process, loose garbage generally needs to be fully compressed and reduced in the garbage truck box to ensure a high loading mass.

[0045] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0046] Please refer to Figures 1 to 3The embodiment of the present invention provides a self-loading garbage truck 10 for loading, unloading and transporting garbage. The self-loading garbage truck 10 can fully compress the garbage, improve the garbage compression ratio, increase the actual loading mass of the garbage truck, reduce the number of garbage transportation times, and reduce the actual transportation cost of garbage.

[0047] It should be noted that the self-loading garbage truck 10 includes a garbage truck body 200 and a garbage compression device 100. The garbage compression device 100 is installed on the garbage truck body 200, and the garbage compression device 100 is used to contain garbage and realize garbage compression, and the garbage truck body 200 is used to realize garbage transportation.

[0048] The garbage compression device 100 includes a garbage bin 110, a slide mechanism 120, a first driving member 130, a first scraper 140, a second driving member 150 and a second scraper 160. An opening 111 is provided at the top of the garbage bin 110, and the opening 111 is used for external garbage to be put into the garbage bin 110. When the amount of garbage put in is large, the garbage may come out of the opening 111, that is, the height of the top of the garbage accumulation may be greater than the height of the position where the opening 111 is located. The slide mechanism 120 is slidably installed in the opening 111, and the first driving member 130 and the first scraper 140 are both hinged to the slide mechanism 120, and the slide mechanism 120 can synchronously drive the first driving member 130 and the first scraper 140 to move relative to the garbage bin 110. The first driving member 130 is hinged to the first scraper 140, and the first driving member 130 can drive the first scraper 140 to rotate relative to the slide mechanism 120. The second driving member 150 and the second scraper 160 are both hinged to the first scraper 140, and the second driving member 150 is hinged to the second scraper 160, and the second driving member 150 can drive the second scraper 160 to rotate relative to the first scraper 140. Specifically, the first driving member 130 is used to adjust the posture of the first scraper 140, and the first scraper 140 can compress the garbage during the posture adjustment process; the second driving member 150 is used to adjust the posture of the second scraper 160, and the second scraper 160 can compress the garbage during the posture adjustment process; the slide mechanism 120 is used to drive the first scraper 140 and the second scraper 160 to push the garbage in the garbage bin 110 in one direction to compress the garbage in the garbage bin 110; the slide mechanism 120, the first scraper 140 and the second scraper 160 work together to achieve full compression of the garbage, improve the garbage compression ratio, increase the actual loading mass of the garbage truck, reduce the number of garbage transportation, and reduce the actual transportation cost of garbage.

[0049] In this embodiment, the garbage bin 110 is horizontally arranged on the garbage truck body 200, that is, the opening 111 is located on a horizontal plane, and the slide mechanism 120 can slide in a horizontal direction. Specifically, the sliding direction of the slide mechanism 120 is the length direction of the garbage bin 110, that is, the length direction of the garbage truck body 200, so as to compress the garbage in the garbage bin 110 toward the front direction of the garbage truck body 200. However, it is not limited to this. In other embodiments, the sliding direction of the slide mechanism 120 can also be the width direction of the garbage bin 110, that is, the garbage is compressed along the width direction of the garbage bin 110, and the sliding direction of the slide mechanism 120 is not specifically limited.

[0050] It is worth noting that the width of the first scraper 140 is equal to the width of the second scraper 160, which is also equal to the width of the garbage bin 110, that is, there is no gap or the gap is very small between the first scraper 140 and the two side walls of the garbage bin 110, and there is no gap or the gap is very small between the second scraper 160 and the two side walls of the garbage bin 110, thereby ensuring that the first scraper 140 and the second scraper 160 can push and compress the garbage in the entire garbage bin 110 driven by the slide mechanism 120, prevent the garbage from leaking out of the gap, and improve the garbage compression efficiency.

[0051] The first scraper 140 includes a scraper arm 141 and a connecting arm 142 which are connected to each other. In this embodiment, the scraper arm 141 and the connecting arm 142 are integrally formed to improve the connection strength. Specifically, the connection between the scraper arm 141 and the connecting arm 142 is hinged to the slide mechanism 120, that is, the first scraper 140 can rotate relative to the slide mechanism 120 at the connection between the scraper arm 141 and the connecting arm 142. One end of the connecting arm 142 away from the scraper arm 141 is hinged to the first driving member 130 and the second driving member 150 at the same time. The first driving member 130 can drive the entire first scraper 140 to rotate relative to the slide mechanism 120 through the connecting arm 142, and the connecting arm 142 can support and limit the second driving member 150. One end of the scraper arm 141 away from the connecting arm 142 is hinged to the second scraper 160, and the scraper arm 141 is used to support and limit the second scraper 160.

[0052] Preferably, the scraping arm 141 and the connecting arm 142 have the same shape and size to ensure balanced force at both ends of the first scraper 140, improve the reliability and durability of the first scraper 140, extend the service life of the first scraper 140, facilitate processing and production, and reduce processing costs.

[0053] The slide mechanism 120 includes a third driving member 121, a slide 122 and a slider 123. A guide slot 112 is provided on the inner wall of the opening 111. The third driving member 121 is installed on the garbage bin 110 and is in transmission connection with the slide 122. The third driving member 121 can drive the slide 122 to move. The first driving member 130 and the first scraper 140 are both hinged on the slide 122. The slide 122 can support and limit the first driving member 130 and the first scraper 140. Specifically, the slide 122 is connected to the slider 123. The slider 123 is slidably matched with the guide slot 112. The extension direction of the guide slot 112 is the same as the driving direction of the third driving member 121. The slider 123 can slide relative to the guide slot 112. The guide slot 112 can guide and limit the slider 123 to ensure that the sliding process of the slide 122 is stable and reliable.

[0054] Preferably, there are two guide slots 112 and two sliders 123, and the two guide slots 112 are relatively arranged on both sides of the garbage bin 110. Each slider 123 is slidably matched with a slot. The two guide slots 112 and the two sliders 123 work together to further improve the sliding stability of the slider 122, prevent the slider 122 from tilting or rotating, and improve safety. In this embodiment, there are two third driving members 121, each of which is connected to a slider 123. The two third driving members 121 act synchronously to simultaneously drive the two sliders 123 to slide relative to the two guide slots 112, thereby driving the slider 122 to move.

[0055] In this embodiment, the first driving member 130, the second driving member 150 and the third driving member 121 are all oil cylinders, but are not limited to this. In other embodiments, the first driving member 130, the second driving member 150 and the third driving member 121 can all be electric cylinders or pneumatic cylinders, and the types of the first driving member 130, the second driving member 150 and the third driving member 121 are not specifically limited.

[0056] Please refer to Figures 4 to 9 The present invention also provides a control method for a garbage compression device, which is used to control the above-mentioned garbage compression device 100, comprising the following steps:

[0057] Step S10 : using the first driving member 130 to synchronously drive the first scraper 140 , the second driving member 150 and the second scraper 160 to rotate, so that the second scraper 160 and a portion of the first scraper 140 extend into the opening 111 .

[0058] It should be noted that before step S10, it is necessary to determine whether the stacking height of the garbage in the garbage bin 110 meets the requirements. When the stacking height of the garbage in the garbage bin 110 is higher than the position of the opening 111 and the height difference reaches a certain value, it is determined that the stacking height of the garbage in the garbage bin 110 meets the requirements. At this time, the garbage compression device 100 is started, and the slide mechanism 120 is used to synchronously drive the first scraper 140 and the second scraper 160 to approach one end of the garbage bin 110 (that is, the rear end of the garbage truck body 200). During this process, the end of the second scraper 160 away from the second driving member 150 is tilted upward and extends out of the opening 111. The opening angle of the second scraper 160 is relatively large, so as to push part of the garbage protruding from the opening 111 forward and fall into the opening 111 to prevent the garbage from spilling.

[0059] Further, when the slide mechanism 120 moves to the extreme position, the position of the end of the second scraper 160 away from the second driving member 150 corresponds to the end position of the opening 111, and step S10 can be performed at this time. In step S10, the first driving member 130 is controlled to extend to synchronously drive the first scraper 140, the second driving member 150 and the second scraper 160 to rotate relative to the slide 122, so that the second scraper 160 and part of the first scraper 140 extend into the opening 111. In this process, the second scraper 160 and part of the first scraper 140 work together to squeeze the garbage diagonally downward.

[0060] Step S20: utilizing the second driving member 150 to drive the second scraper 160 to rotate, so that the second scraper 160 forms an initial preset angle with the horizontal plane.

[0061] It should be noted that in step S20, the first driving member 130 is kept stationary, and the second driving member 150 is controlled to extend to drive the second scraper 160 to rotate relative to the first scraper 140. When the second scraper 160 rotates to the limit position, an initial preset angle is formed between the second scraper 160 and the horizontal plane. For ease of understanding, the free end of the second scraper 160 is represented as point A, the hinge point of the second scraper 160 and the first scraper 140 is represented as B, and the angle between the AB line and the horizontal line is the preset angle a. The preset angle a in step S20 is the initial preset angle.

[0062] Step S30 : using the slide plate mechanism 120 to synchronously drive the first scraper 140 and the second scraper 160 to compress the garbage in the garbage bin 110 .

[0063] It should be noted that in step S30, the third driving member 121 is used to drive the slide plate 122 to slide relative to the garbage bin 110, so as to synchronously drive the first scraper 140 and the second scraper 160 to move. The sliding direction of the slide plate 122 is the same as the direction of the opening 111 at an angle between the first scraper 140 and the second scraper 160, so as to ensure that the garbage in the garbage bin 110 can be close to one end of the garbage bin 110 (that is, the front end of the garbage truck body 200) and compressed under the joint action of the first scraper 140 and the second scraper 160.

[0064] Furthermore, in step S30, the first driving member 130 and the second driving member 150 remain stationary, and the power sources of the first scraper 140 and the second scraper 160 both come from the third driving member 121. When the third driving member 121 drives the first scraper 140 and the second scraper 160 to move to the extreme position (the garbage is compressed to a certain extent), the third driving member 121 reaches the maximum pressure. At this time, the reaction force of the compressed garbage on the first scraper 140 and the second scraper 160 is balanced with the maximum pressure of the third driving member 121.

[0065] It is worth noting that the maximum pressure of the third driving member 121 is denoted as F, the effective height of the first scraper 140 and the second scraper 160 on the garbage is denoted as H, the width of the garbage bin 110 is denoted as W, and the maximum pressure of the compressed garbage on the first scraper 140 and the second scraper 160 in the horizontal direction is P. At this time, the static equilibrium equation of the system is: P×H×W=F. According to this relationship, when the maximum pressure F of the third driving member 121 is constant, the larger the effective height H of the first scraper 140 and the second scraper 160 on the garbage, the smaller the maximum pressure P of the compressed garbage on the first scraper 140 and the second scraper 160 in the horizontal direction, the smaller the density of the compressed garbage, and the smaller the actual loading mass of the whole vehicle. However, if the effective action height H is simply reduced in order to increase the maximum pressure P on the garbage, the proportion of garbage that is not fully compressed at the bottom of the garbage bin 110 will be high, and the actual loading quality may not be improved. Therefore, the present invention proposes a subsequent step to fully press the garbage downward and toward the front end of the vehicle through at least two compressions with different compression conditions each time, thereby improving the garbage compression ratio and increasing the actual loading quality.

[0066] Step S31: using the first driving member 130 to synchronously drive the first scraper 140, the second driving member 150 and the second scraper 160 to rotate, so that the second scraper 160 forms an intermediate preset angle with the horizontal plane, and the intermediate preset angle is greater than the initial preset angle.

[0067] It should be noted that in step S31, the first driving member 130 is controlled to be shortened to a certain extent so that the second scraper 160 forms an intermediate preset angle with the horizontal plane. The preset angle a in step S31 is the intermediate preset angle.

[0068] Step S32: using the slide plate mechanism 120 to drive the second scraper 160 to compress the garbage in the garbage bin 110 .

[0069] It should be noted that in step S32, the first driving member 130 and the second driving member 150 remain stationary, and the third driving member 121 is used to drive the slide plate 122 to slide relative to the garbage bin 110, so as to synchronously drive the first scraper 140 and the second scraper 160 to move. In this process, since the intermediate preset angle is greater than the initial preset angle, the effective action height H of the first scraper 140 and the second scraper 160 on the garbage will be reduced, and the maximum pressure P of the compressed garbage on the first scraper 140 and the second scraper 160 in the horizontal direction will increase, and the garbage will be further compressed under the pressure to improve the actual loading quality.

[0070] In this embodiment, step S31 and step S32 are repeated alternately in sequence, and the intermediate preset angle in multiple steps S31 increases successively, that is, the effective action height H in multiple steps S32 decreases successively, and the maximum pressure P increases successively, and the garbage is fully compressed in the multiple compression processes, further improving the garbage compression ratio and increasing the actual loading mass. However, it is not limited to this. In other embodiments, step S31 and step S32 may not be performed, or step S31 and step S32 may be performed only once, and the number of times step S31 and step S32 are performed is not specifically limited.

[0071] Step S40 : using the first driving member 130 to synchronously drive the first scraper 140 , the second driving member 150 and the second scraper 160 to rotate to the extreme position, so that the second scraper 160 is perpendicular to the horizontal plane and the first scraper 140 is retracted out of the garbage bin 110 .

[0072] It should be noted that, in step S40, the first driving member 130 is controlled to be shortened to the extreme position so that the second scraper 160 is set perpendicular to the horizontal plane, that is, the preset angle a in step S40 is equal to 90 degrees. At this time, the first scraper 140 is completely retracted out of the garbage bin 110 under the action of the first driving member 130 and no longer contacts the garbage.

[0073] Step S50 : using the slide plate mechanism 120 to drive the second scraper 160 to compress the garbage in the garbage bin 110 .

[0074] It should be noted that in step S50, the first driving member 130 and the second driving member 150 remain stationary, and the third driving member 121 is used to drive the slide plate 122 to slide relative to the garbage bin 110, so as to synchronously drive the first scraper 140 and the second scraper 160 to move. In this process, since the preset angle reaches the maximum (90 degrees) and the first scraper 140 is completely retracted from the garbage bin 110, only the second scraper 160 compresses the garbage. At this time, the effective height H of the first scraper 140 and the second scraper 160 on the garbage reaches the minimum, and the maximum pressure P of the compressed garbage on the first scraper 140 and the second scraper 160 in the horizontal direction reaches the maximum. The garbage will be further compressed under the pressure to improve the actual loading quality.

[0075] In other words, the depth to which the first scraper 140 and the second scraper 160 are jointly extended into the opening 111 in step S30 is greater than the depth to which the second scraper 160 is extended into the opening 111 in step S50, that is, the effective height H of the first scraper 140 and the second scraper 160 on the garbage in step S30 is greater than the effective height H of the first scraper 140 and the second scraper 160 on the garbage in step S50; the pressure exerted by the first scraper 140 and the second scraper 160 on the garbage in step S30 is less than the pressure exerted by the second scraper 160 on the garbage in step S50, that is, the maximum pressure P of the compressed garbage on the first scraper 140 and the second scraper 160 in the horizontal direction in step S30 is less than the maximum pressure P of the compressed garbage on the first scraper 140 and the second scraper 160 in the horizontal direction in step S50.

[0076] The garbage compression device 100 provided by the embodiment of the present invention has an opening 111 on the top of the garbage bin 110, and the slide mechanism 120 can be slidably installed in the opening 111. The first driving member 130 and the first scraper 140 are both hinged to the slide mechanism 120, the first driving member 130 is hinged to the first scraper 140, the second driving member 150 and the second scraper 160 are both hinged to the first scraper 140, the second driving member 150 is hinged to the second scraper 160, the first driving member 130 is used to adjust the posture of the first scraper 140, the second driving member 150 is used to adjust the posture of the second scraper 160, and the slide mechanism 120 is used to drive the first scraper 140 and the second scraper 160 to compress the garbage in the garbage bin 110. Compared with the prior art, the garbage compression device 100 provided by the present invention can fully compress the garbage, improve the garbage compression ratio, increase the actual loading mass of the garbage truck, reduce the number of garbage transportation, and reduce the actual transportation cost of the garbage, because it adopts the first scraper 140 hinged to the first driving member 130 and the second scraper 160 hinged to the second driving member 150. The control method of the garbage compression device provided by the present invention is simple and convenient, the garbage compression efficiency is high, and the actual loading mass of the self-loading and unloading garbage truck 10 is large, and the garbage compression effect is good.
