DETAILED DESCRIPTION

[0034] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0035] In a farm, a manure conveying device is a device used to collect and transport manure, such as chicken manure. The structure of the manure conveying device is similar to that of a common conveying device and belongs to the prior art. Here, only the main structure and working process of the manure conveying device are briefly described as follows:

[0036] like Figure 1 A manure transporting equipment shown in the figure includes a column 100, and a plurality of groups of columns 100 are arranged at intervals according to actual needs. The lower end of the column 100 is fixed on the ground, and the upper end of the column 100 is symmetrically fixedly connected with a manure transporting belt bracket 101, and there is a gap between the two manure transporting belt brackets 101. One end of the manure transporting belt bracket 101 is a discharge end, and a driven wheel 103 is rotatably installed at the discharge end. A plurality of groups of rollers 104 are rotatably installed between the two manure transporting belt brackets 101, and a manure transporting belt 102 is hung together with the rollers 104 and the driven wheels 103. The manure transporting belt 102 rotates around the rollers 104 and the driven wheels 103, and is unloaded from the discharge end to the chicken manure collection point to complete the transportation of chicken manure.

[0037] It should be specially noted that, in the manure transporting equipment, the outer side surface of the manure transporting belt 102 is in contact with the chicken manure, the inner side surface of the manure transporting belt 102 is not in contact with the chicken manure, and the rollers 104 are arranged in two rows, the rollers in the upper row are in contact with the inner side surface of the manure transporting belt 102, and the rollers in the lower row are in contact with the outer side surface of the manure transporting belt 102. During the process of the manure transporting belt 102 transporting chicken manure, the rollers in the lower row are easily adhered to the chicken manure.

[0038] When in use, after the chicken manure is placed on the manure conveying belt 102, the manure conveying belt 102 drives the chicken manure to move toward the unloading end of the manure conveying belt bracket 101. During the movement of the manure conveying belt 102, the roller 104 plays a supporting and guiding role. When the manure conveying belt 102 rotates past the driven wheel 103, the chicken manure on the manure conveying belt 102 falls downward, thereby detaching from the manure conveying belt 102.

[0039] like Figure 1-2 As shown, this embodiment provides a feces conveying belt cleaning device, which includes:

[0040] The cleaning assembly includes a scraper 111 rotatably connected to the manure conveying belt support 101, one end of the scraper 111 is in sliding contact with the surface of the manure conveying belt 102, and the other end of the scraper 111 is symmetrically installed with an adjustment device, which is used to adjust the pressure of the scraper 111 on the manure conveying belt 102;

[0041] The tensioning assembly includes a tensioning tube 130 respectively arranged on both sides of the feces conveying belt 102. A tensioning rod 131 is inserted into the lumen of the tensioning tube 130 and is slidably connected thereto. One end of the tensioning rod 131 close to the feces conveying belt 102 passes through the tensioning tube 130 and is rotatably connected thereto, and the tensioning roller 132 is in sliding contact with the surface of the feces conveying belt 102.

[0042] Furthermore, the tensioning assembly also includes an adjusting roller 139 , which is rotatably connected to the manure conveying belt support 101 , and the adjusting roller 139 is in sliding contact with the surface of the manure conveying belt 102 .

[0043] Furthermore, the cleaning assembly includes a first cleaning assembly 110 and a second cleaning assembly 120 . The scraper 111 of the first cleaning assembly 110 cooperates with the driven wheel 103 , and the scraper 111 of the second cleaning assembly 120 cooperates with the adjustment roller 139 .

[0044] It should be specially noted that the scraper 111 is rotatably installed between the two feces conveying belt supports 101 , and the length of the scraper 111 is greater than the width of the feces conveying belt 102 , so as to ensure that the feces on the feces conveying belt 102 can be scraped off.

[0045] The scraper 111 serves to scrape away the feces on the feces conveying belt 102. The material of the scraper 111 can be a wooden board, a plastic board, or a metal board. The material, processing, and installation process belong to the prior art and can be easily obtained, so this embodiment will not be described in detail.

[0046] In this embodiment, the tensioning assembly is disposed between the first cleaning assembly 110 and the second cleaning assembly 120, wherein:

[0047] The first cleaning assembly 110 is disposed below the driven wheel 103 , and a scraper 111 of the first cleaning assembly 110 is disposed below the driven wheel 103 . The upper end of the scraper 111 of the first cleaning assembly 110 is in sliding contact with the surface of the feces conveying belt 102 at the driven wheel 103 .

[0048] The second cleaning component 120 is arranged below the adjusting roller 139 , the length of the adjusting roller 139 is adapted to the width of the manure conveying belt 102 , and the upper end of the scraper 111 of the second cleaning component 120 is in sliding contact with the surface of the manure conveying belt 102 at the adjusting roller 139 .

[0049] The driven wheel 103 and the adjusting roller 139 also play a certain supporting role on the scraper 111 to prevent the scraper 111 from pressing too hard and damaging the manure conveying belt 102.

[0050] The tensioning tube 130 is symmetrically installed on the feces conveying belt bracket 101 on both sides of the feces conveying belt 102. A tensioning rod 131 is inserted into the lumen of the tensioning tube 130 and is slidably connected. The lower end of the tensioning rod 131 passes through the tensioning tube 130 and is rotatably connected to the tensioning roller 132. The length of the tensioning roller 132 is adapted to the width of the feces conveying belt 102. The tensioning roller 132 is in sliding contact with the surface of the feces conveying belt 102. Relative sliding occurs between the tensioning roller 132 and the tensioning tube 130, so that the position of the tensioning roller 132 changes, thereby changing the pressure of the tensioning roller 132 on the feces conveying belt 102, ensuring that the feces conveying belt 102 is in a tensioned state.

[0051] With the cooperation of the tensioning roller 132 and the adjusting roller 139, the manure conveying belt 102 can always maintain a certain tension state. When the manure conveying belt 102 rotates over the scraper 111 on the first cleaning component 110 and the second cleaning component 120, it can slide over the scraper 111 more smoothly, ensuring effective scraping of chicken manure while extending the service life of the manure conveying belt.

[0052] Before use, adjust the adjustment devices in the first cleaning component 110 and the second cleaning component 120 to adjust the pressure of the scraper 111 of the first cleaning component 110 and the second cleaning component 120 on the feces conveying belt 102 so that the upper end of the scraper 111 is in sliding contact with the feces conveying belt 102.

[0053] The manure conveying equipment is started, and the manure conveying belt 102 rotates around the manure conveying belt bracket 101 and toward the unloading end of the manure conveying belt bracket 101. After the chicken manure is placed on the manure conveying belt 102, the manure conveying belt 102 drives the chicken manure to move toward the unloading end. During the movement of the manure conveying belt 102, the roller 104 plays a supporting and guiding role to ensure the stability of the movement of the manure conveying belt 102.

[0054] When the manure conveying belt 102 rotates past the driven wheel 103 , the chicken manure on the manure conveying belt 102 falls downward, thereby being detached from the manure conveying belt 102 .

[0055] The manure conveying belt 102 continues to rotate, and the surface of the manure conveying belt 102 in contact with the chicken manure slides over the scraper 111 of the first cleaning component 110 . The chicken manure adhered to the manure conveying belt 102 is scraped off by the scraper 111 and slides off the scraper 111 .

[0056] The manure conveying belt 102 continues to rotate, and the surface of the manure conveying belt 102 in contact with the chicken manure slides over the scraper 111 of the second cleaning component 110. The scraper 111 of the second cleaning component 110 scrapes the manure conveying belt 102 for a second time to avoid residual chicken manure, thereby effectively ensuring the cleaning effect of chicken manure. When the manure conveying belt 102 continues to rotate, when the surface of the manure conveying belt 102 in contact with the chicken manure, that is, the outer side surface, slides over the roller 104, no chicken manure will adhere to the surface of the roller 104, thereby ensuring the normal use of the manure conveying belt 102.

[0057] When the tension of the manure conveying belt 102 decreases due to long-term use, the tensioning assembly is adjusted to make the tensioning rod 131 slide outward along the tensioning tube 130, driving the tensioning roller 132 to move downward, thereby increasing the length of the manure conveying belt 102 between the driven wheel 103, the tensioning roller 132 and the adjustment roller 139, thereby completing the tensioning of the manure conveying belt 102.

[0058] like Figure 1-5 As shown, in one embodiment of the feces conveying belt cleaning device of the utility model,

[0059] Furthermore, the adjustment device includes an adjustment sleeve 112, the end of the adjustment sleeve 112 away from the scraper 111 is fixedly connected to the feces conveying belt bracket 101, an adjustment rod 113 is passed through and slidably connected in the lumen of the adjustment sleeve 112, and the end of the adjustment rod 113 close to the scraper 111 passes through the adjustment sleeve 112 and is hinged to the scraper 111.

[0060] Furthermore, the adjustment sleeve 112 is sleeved and slidably connected with an adjustment spring 114, one end of the adjustment sleeve 112 away from the scraper 111 is threadedly connected with an adjustment nut 115, one end of the adjustment spring 114 is connected to the adjustment rod 113, and the other end of the adjustment spring 114 is in sliding contact with the adjustment nut 115.

[0061] Furthermore, a limiting plate 116 is fixedly sleeved on one end of the adjusting rod 113 away from the adjusting sleeve 112 , and one end of the adjusting spring 114 is connected to the limiting plate 116 .

[0062] Furthermore, an adjusting washer 117 is sleeved on and slidably connected to the adjusting sleeve 112 . The side of the adjusting washer 117 close to the adjusting nut 115 is in sliding contact with the adjusting nut 115 , and the side of the adjusting washer 117 away from the adjusting nut 115 is in sliding contact with the adjusting spring 114 .

[0063] Furthermore, a tensioning spring 133 is passed through and slidably connected in the lumen of the tensioning tube 130. The tensioning spring 133 is sleeved on the tensioning rod 131. The tensioning spring 133 is in sliding contact with the side wall of the tensioning rod 131. One end of the tensioning rod 131 close to the tensioning roller 132 is threadedly connected with a tensioning nut 134. One end of the tensioning spring 133 is connected to the inner wall of the tensioning tube 130, and the other end of the tensioning spring 133 is in sliding contact with the tensioning nut 134.

[0064] Furthermore, one end of the tensioning rod 131 away from the tensioning roller 132 passes through the tensioning tube 130 and is fixedly connected to the limiting block 135 .

[0065] Furthermore, a tensioning washer 136 is sleeved and slidably connected to one end of the tensioning rod 131 close to the tensioning roller 132 , and the side of the tensioning washer 136 close to the tensioning nut 134 is in sliding contact with the tensioning nut 134 , and the side of the tensioning washer 136 away from the tensioning nut 134 is in sliding contact with the tensioning spring 133 .

[0066] Furthermore, the tensioning roller 132 and the adjusting roller 139 are located on the same side of the feces conveying belt 102 .

[0067] Furthermore, the lower edge of the tensioning roller 132 is higher than the lower edge of the adjusting roller 139 .

[0068] In this embodiment, the two adjustment sleeves 112 of the first cleaning component 110 are fixedly installed on the feces conveying belt bracket 101 on both sides of the feces conveying belt 102 by bolts, and the adjustment rod 113 in the adjustment sleeve 112 passes through the adjustment sleeve 112 at one end close to the scraper 111 and is hinged to the scraper 111.

[0069] A support plate 118 is symmetrically fixedly connected to the column 100 near the discharge end, and the two adjustment sleeves 112 of the second cleaning component 120 are fixedly installed on the support plate 118 by bolts. The adjustment rod 113 in the adjustment sleeve 112 passes through the adjustment sleeve 112 at one end near the scraper 111 and is hinged to the scraper 111.

[0070] The adjusting sleeve 112 is fixed by bolts, which is convenient for maintenance and replacement of the adjusting device on the one hand, and on the other hand, the angle of the adjusting sleeve 112 can be adjusted after the bolts are loosened, so the applicability is stronger.

[0071] A thread is provided on the outer wall of the adjusting sleeve 112, and the adjusting sleeve 112 is threadedly connected with a corresponding adjusting nut 115. An adjusting washer 117 is sleeved and slidably arranged on the adjusting sleeve 112. By rotating the adjusting nut 115, the distance between the adjusting washer 117 and the limiting plate 116 is changed by changing the position of the adjusting nut 115 on the adjusting sleeve 112, thereby changing the deformation of the adjusting spring 114 and adjusting the elastic force of the adjusting spring 114.

[0072] The tensioning tube 130 is symmetrically installed on the feces conveying belt bracket 101 on both sides of the feces conveying belt 102. The size of the limit block 135 is larger than the diameter of the lumen of the tensioning tube 130. The limit block 135 plays a limiting role to prevent the tensioning rod 131 from slipping out of the lumen of the tensioning tube 130.

[0073] like Figure 2 As shown, the tensioning roller 132 and the adjusting roller 139 are both located on the inner side of the manure conveying belt 102 , and the lower edge of the tensioning roller 132 is higher than the lower edge of the adjusting roller 139 .

[0074] like Figure 5As shown, a cover 137 is fixedly installed at one end of the tensioning tube 130 away from the tensioning roller 132, and the end of the tensioning rod 131 away from the tensioning roller 132 passes through the cover 137 and is slidably connected to the cover 137. The end of the tensioning rod 131 away from the tensioning roller 132 passes through the cover 137 and is fixedly connected to the limit block 135.

[0075] A thread is provided on the outer wall of the tensioning rod 131, and a matching tensioning nut 134 is threadedly connected to the tensioning rod 131. A tensioning washer 136 is sleeved and slidably arranged on the tensioning rod 131. One end of the tensioning spring 133 is connected to the cover 137, and the other end of the tensioning spring 133 is in sliding contact with the tensioning washer 136.

[0076] By rotating the tensioning nut 134 and changing the distance between the tensioning washer 136 and the cover 137 , the deformation of the tensioning spring 133 is changed, thereby adjusting the elastic force of the tensioning spring 133 .

[0077] After the elastic force of the tensioning spring 133 changes, the position of the tensioning roller 132 changes under the action of the elastic force of the tensioning spring 133, thereby changing the pressing force of the tensioning roller 132 on the feces conveying belt 102, ensuring that the feces conveying belt 102 is in a tensioned state.

[0078] During use, the scrapers 111 of the first cleaning component 110 and the second cleaning component 120 are in contact with the feces conveying belt 102, and the tensioning roller 132 is in contact with the feces conveying belt 102. For example, to increase the pressure of the scraper 111 on the feces conveying belt 102, the adjusting nut 115 is rotated. Under the action of the thread between the adjusting nut 115 and the adjusting sleeve 112, the adjusting nut 115 drives the adjusting washer 117 to slide along the adjusting sleeve 112. The adjusting washer 117 approaches the limit plate 116, and the adjusting spring 114 is compressed. The elastic force of the adjusting spring 114 increases, and the pressure of the scraper 111 on the feces conveying belt 102 is increased by the adjusting rod 113, thereby increasing the pressure of the scraper 111 on the feces conveying belt 102.

[0079] One end of the adjustment spring 114 is in sliding contact with the adjustment washer 117, and the other end of the adjustment spring 114 can be in sliding contact with the limit plate 116 or fixedly connected. Since the adjustment spring 114 and the adjustment washer 117 are in sliding contact, when the adjustment nut 115 is rotated, the adjustment spring 114 will only extend or shorten, and will not produce relative rotation with the adjustment sleeve 112, thereby avoiding damage to the adjustment spring 114.

[0080] Taking increasing the tension of the manure conveying belt 102 as an example, the tensioning nut 134 is rotated. Under the action of the thread between the tensioning nut 134 and the tensioning rod 131, the tensioning nut 134 drives the tensioning washer 136 to slide along the tensioning rod 131, and the tensioning washer 136 moves away from the tensioning roller 132. The tensioning spring 133 is compressed, the elastic force of the tensioning spring 133 increases, and the tensioning roller 132 moves downward, increasing the length of the manure conveying belt 102 at the driven wheel 103, the tensioning roller 132 and the adjustment roller 139, changing the pressure of the tensioning roller 132 on the manure conveying belt 102, and ensuring that the manure conveying belt 102 is in a tensioned state.
