[0002] In the field of wood processing, in order to facilitate transportation and processing, wood is generally required to be classified and stacked according to size. Most traditional stacking devices stack wood directly without pre-sorting, but in actual production, affected by the size and location of the wood, the mechanical structure and algorithm of the stacking device are often very complicated, which not only increases the cost and difficulty, but also reduces the reliability of stacking.

[0003] In addition, wood is currently pre-sorted before palletizing operations to reduce the complexity of the palletizing stage. However, existing pre-sorting devices generally use multiple power sources, and multiple actions need to be coordinated with each other, which increases the complexity of the machinery to a certain extent. An overly complex mechanical structure will not only increase the equipment cost, but also affect the reliability of the structure.

[0004] Therefore, in order to reduce the workload of the palletizing process and improve the reliability of the palletizing process, designing a reasonable and practical wood pre-sorting device is of great significance for the production and processing of the wood industry. Utility Model Content

The spiral scraper mechanism includes a scraper, a spiral push rod and a gear. The scraper is a long strip with an L-shaped cross-section.

The outer sides of each corresponding two single sections between the two groups of chains are connected and fixed to the two ends of the bottom support arm of a scraper. The vertical support arm of the scraper is located on the rear side of the movement direction of the two groups of chains. The edge of the supporting frame is laterally fixed with a rack.

A feeding station is set at the lateral end of the sorting table. The feeding station is aligned with one end of the wood transported to the sorting table. A discharging station is set at the longitudinal end of the sorting table.

[0007] Furthermore, the feeding station adopts a feeding platform, which is a belt conveyor and a side baffle is fixedly arranged on one side edge along the conveying direction, and one end of the wood is aligned by the side baffle and then sent to the sorting table.

DETAILED DESCRIPTION

[0016] The technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0017] like Figure 1 to Figure 5 As shown, a pre-sorting device for wood conveyed by a scraper spiral driven by a single power source comprises a sorting platform 1, a feeding platform 2 and a discharging ramp platform 3.

[0018] Combination Figure 2 to Figure 5 As shown, the sorting platform 1 includes a supporting frame 13, a power assembly 14 and a plurality of spiral scraper mechanisms 11. The supporting frame 13 is used to support the main body of the sorting platform 1, and the power assembly 14 is used to control the movement of the plurality of spiral scraper mechanisms 11. The spiral scraper mechanisms 11 are used to sort wood materials 4 of different lengths.

[0019] Combination Figure 5As shown, the power assembly 14 includes a driving shaft 143, a driven shaft 144, a reduction motor 146 and two sets of chains 141. The driving shaft 143 and the driven shaft 144 are arranged horizontally and side by side and are rotatably mounted at the two ends of the carrier frame 13 through two bearing seats 145, respectively. Two sprockets 142 are fixed to the driving shaft 143 and the driven shaft 144 adjacent to the two ends, respectively. The two sets of chains 141 are arranged side by side and are respectively sleeved between the two sprockets 142 corresponding to the driving shaft 143 and the driven shaft 144 in the horizontal direction. The reduction motor 146 is fixedly mounted on the edge of the carrier frame 13 and connected to the transmission driving shaft 143.

[0020] Combination Figure 4-5 As shown, the number of the spiral scraper mechanism 11 is the same as the number of sections of the chain 141. The spiral scraper mechanism 11 includes a scraper 111, a spiral push rod 112 and a gear 114. The scraper 111 is a long strip with an L-shaped cross section. The spiral push rod 112 is rotatably mounted on the inner side of the scraper 111 through two bearing seats 113, and the gear 114 is coaxially fixed to the end of the spiral push rod 112. The outer sides of each corresponding two single sections between the two groups of chains 141 are connected and fixed to the two ends of the bottom support arm of a scraper 111, and the vertical support arm of the scraper 111 is located at the rear side of the movement direction of the two groups of chains 141.

[0021] Combination Figure 2 As shown, the edge of the supporting frame 13 is laterally fixed with a rack 12 , and during the movement of the two sets of chains 141 , the spiral scraper mechanism 11 located above is meshed with the rack 12 through the gear 114 to drive the spiral push rod 112 to rotate.

[0022] Combination Figure 1 As shown, a feeding platform 2 is provided at the transverse end of the sorting platform 1 as a feeding station, and the feeding platform 2 is a belt conveyor 21, and a side baffle 22 is fixedly provided on one side edge along the conveying direction, and one end of the wood 4 is aligned by the side baffle 22 and then sent to the sorting platform 1. A discharging ramp 3 is provided at the longitudinal end of the sorting platform 1 as a discharging station, and the top end of the discharging ramp 3 is connected to the longitudinal end of the sorting platform 1 as a whole, and a limit plate 31 is provided at the bottom end of the discharging ramp 3 to support the sorted wood 4.

[0023] When pre-sorting wood 4 of different lengths, one end of the wood 4 is pressed against the side baffle 22 on the belt conveyor 21 of the feeding station to ensure that one end of the wood 4 is aligned and then sent to the sorting platform 1. Under the action of the power assembly 14, the sorting platform 1 drives the driving shaft 143 to rotate through the reduction motor 146. The driving shaft 143 rotates while driving the driven shaft 144. The two sets of chains 141 move with the sprocket 142. At this time, all the spiral scraper mechanisms 11 circulate with the two sets of chains 141. In addition, due to the setting of the rack 12, during the movement of all the spiral scraper mechanisms 11 carried by the two sets of chains 141, the spiral scraper mechanism 11 that moves to the top will also realize the rotation of the internal spiral push rod 112 through the cooperation of the gear 114 and the rack 12. Therefore, after the wood 4 is sent to the sorting table 1 by the belt conveyor 21, it falls into the spiral scraper mechanism 11 that moves to the upper part and is adjacent to the belt conveyor 21. While moving laterally along the moving direction of the chain 141, it also moves longitudinally under the friction of the spiral push rod 112. Under the combined force of the lateral displacement and the longitudinal displacement, the wood 4 moves obliquely toward the discharge station. Since the combined force acts on wood 4 of different lengths for different durations, the longer the wood 4 is, the longer it lasts, and it is then sent to a position farther from the feeding station and then sent out. The shorter the wood 4 is, the shorter it lasts, and the shorter it lasts, and it is then sent to a position closer to the feeding station and then sent out. Finally, wood materials 4 of different lengths slide down different positions along the discharging ramp 3 and are stopped and positioned by the limiting plate 31. The wood materials 4 are arranged on the discharging ramp 3 from small to large in length and from near to far from the feeding station, thus realizing the pre-sorting operation of the wood materials 4 according to different lengths. The overall structure is simple, reliable and easy to use.
