Description
技术领域technical field
本发明涉及一种破碎机，特别涉及一种两段式破碎的圆锥破碎机。The invention relates to a crusher, in particular to a two-stage crushing cone crusher.
背景技术Background technique
圆锥破碎机的动锥外表面与定锥内表面构成的空间叫破碎腔，破碎腔的腔型好坏，对破碎机的破碎效率具有很大的影响。目前，圆锥破碎机的腔型仅仅由一段动锥构成，在破碎时，物料未经预处理，直接由破碎腔进行破碎操作，相当于物料直接对破碎腔产生一个强力的刚性接触，容易加剧破碎腔的磨损，导致圆锥破碎机的使用寿命降低。另外，现有的圆锥破碎机的定锥在破碎腔的出料口上方通常都是采用平直段，这样就使得破碎腔的破碎效率从上向下逐渐增加，从而导致破碎腔在排料口处拥堵，进而导致排料不畅，降低了破碎效率。The space formed by the outer surface of the movable cone and the inner surface of the fixed cone of the cone crusher is called the crushing cavity. The cavity shape of the crushing cavity has a great influence on the crushing efficiency of the crusher. At present, the cavity type of the cone crusher is only composed of a section of moving cone. When crushing, the material is not pretreated, and the crushing operation is directly carried out by the crushing cavity, which is equivalent to a strong rigid contact between the material and the crushing cavity, which is easy to aggravate the crushing. The wear of the cavity will reduce the service life of the cone crusher. In addition, the fixed cone of the existing cone crusher usually adopts a straight section above the discharge port of the crushing chamber, which makes the crushing efficiency of the crushing chamber gradually increase from top to bottom, resulting in the crushing chamber being at the discharge port. Congestion at the place will lead to poor discharge and reduce the crushing efficiency.

本发明的密封系统采用水密封系统，包括球面轴承座19以及安装在球面轴承座19底部的轴承支架20，轴承支架20与支架3固定，轴承支架20的外侧壁上横向设有进水管21，轴承支架20的外壁上还设有环形给水槽22以及环形排水槽23，环形给水槽22与进水管21连接，环形排水槽23与环形给水槽22连接，在第二动锥702底面固定安装有一个球形圈24，球形圈24的中部的底面固定有一个插入轴承支架20的防尘圈25，球形圈24的底部插入环形给水槽22内，球面轴承座19、第一动锥701的底面、轴承支架20三者连接的交界处的间隙内安装有毛毡26，毛毡26在安装前采用润滑油润滑，以便于降低毛毡26的磨损，同时在球形圈24的底部的上方安装一个海绵27。当破碎机工作时，球形圈24将粉尘挡住并使其落入水中，环流水从进水管21流入环形给水槽22中，在环形给水槽22满了后，自动溢到环形排水槽24中去，通过环形排水槽24将带有粉尘的环流水排出机体外，同时利用海绵27的吸水性以及可收缩性，海绵27在正常状态下，泡在环形给水槽22中，当球形圈24脱离水面时，海绵27收缩，且对粉尘进行吸附，从而阻挡粉尘进入机体内部，如果有粉尘通过海绵27漏进机体内时，毛毡26也能够有效的阻挡粉尘通过球面轴承座19、第一动锥701的底面、轴承支架20三者连接的交界处的间隙落到机体的润滑系统内，从而避免了润滑系统受到污染，降低了润滑油的更换频率，降低成本。The sealing system of the present invention adopts a water sealing system, including a spherical bearing housing 19 and a bearing bracket 20 installed at the bottom of the spherical bearing housing 19, the bearing bracket 20 is fixed to the bracket 3, and the outer wall of the bearing bracket 20 is horizontally provided with a water inlet pipe 21, The outer wall of the bearing bracket 20 is also provided with an annular water supply tank 22 and an annular drain tank 23, the annular water supply tank 22 is connected with the water inlet pipe 21, the annular drain tank 23 is connected with the annular water supply tank 22, and the bottom surface of the second movable cone 702 is fixedly installed with A spherical ring 24, the bottom surface of the middle part of the spherical ring 24 is fixed with a dustproof ring 25 inserted into the bearing bracket 20, the bottom of the spherical ring 24 is inserted into the annular water supply tank 22, the bottom surface of the spherical bearing seat 19, the first moving cone 701, Felt 26 is installed in the gap of the junction where the three of bearing bracket 20 are connected, and felt 26 is lubricated with lubricating oil before installation, so as to reduce the wear and tear of felt 26, and a sponge 27 is installed above the bottom of spherical ring 24 simultaneously. When the crusher is working, the spherical ring 24 blocks the dust and makes it fall into the water. The circulating water flows into the annular water supply tank 22 from the water inlet pipe 21. When the annular water supply tank 22 is full, it automatically overflows into the annular drainage tank 24. , through the annular drainage groove 24, the circulating water with dust is discharged out of the body, and at the same time, the water absorption and shrinkability of the sponge 27 are used. Under normal conditions, the sponge 27 is soaked in the annular water supply groove 22. At this time, the sponge 27 shrinks and absorbs the dust, thereby preventing the dust from entering the body. If dust leaks into the body through the sponge 27, the felt 26 can also effectively block the dust from passing through the spherical bearing seat 19 and the first moving cone 701. The gap between the bottom surface of the bottom surface and the junction of the bearing bracket 20 falls into the lubricating system of the body, thereby preventing the lubricating system from being polluted, reducing the frequency of lubricating oil replacement, and reducing costs.
在本发明的主轴6的润滑系统中，摒弃了传统方式的采用长衬套的方式，如图4所示，即偏心轴套5与主轴6之间留有两条间隙，该间隙构成润滑油道29，润滑油液在润滑油道29内运行时是直上直下的，从而造成偏心轴套5顶部供油不足的现象，导致偏心轴套5老化迅速，如图5所示，本发明采用在主轴6的轴身上切削两条呈螺旋形的润滑油道29，当主轴6转动时，润滑油能够沿螺旋形的润滑油道29向上流动，增加了上部的润滑油供应量，另外，为了保证润滑油的流动的通畅，在偏心轴套5与轴承套4齐平的位置处开有缺口28。In the lubrication system of the main shaft 6 of the present invention, the traditional way of using long bushings is abandoned, as shown in Figure 4, that is, there are two gaps between the eccentric shaft sleeve 5 and the main shaft 6, and the gaps constitute lubricating oil. Road 29, when the lubricating oil runs in the lubricating oil passage 29, it runs straight up and down, thus causing insufficient oil supply at the top of the eccentric shaft sleeve 5, resulting in rapid aging of the eccentric shaft sleeve 5, as shown in Figure 5, the present invention adopts the Two helical lubricating oil passages 29 are cut on the shaft body of the main shaft 6. When the main shaft 6 rotates, the lubricating oil can flow upwards along the helical lubricating oil passages 29, which increases the supply of lubricating oil on the top. In addition, in order to ensure The flow of lubricating oil is smooth, and there is a gap 28 at the position where the eccentric shaft sleeve 5 is flush with the bearing sleeve 4 .
本发明将破碎腔通过第一动锥以及第二动锥、第一动锥衬板、第二动锥衬板分为两个部分，由于位于上方的破碎腔的空间大于下方的破碎腔的空间，因而在破碎时，上方的破碎腔能够首先对物料压实以及施加较小的剪力，实现对物料的预处理，当物料移动到位于下方的破碎腔时，能够直接以层压的方式对物料进行破碎，从而降低了破碎腔的冲击磨损，提高了圆锥破碎机的使用寿命。The present invention divides the crushing chamber into two parts through the first movable cone, the second movable cone, the first movable cone liner and the second movable cone liner, because the space of the upper crushing chamber is larger than the space of the lower crushing chamber Therefore, when crushing, the upper crushing chamber can first compact the material and apply a small shear force to realize the pretreatment of the material. When the material moves to the lower crushing chamber, it can be directly laminated. The material is crushed, which reduces the impact wear of the crushing cavity and improves the service life of the cone crusher.
以上所述的仅是本发明的优选实施方式，应当指出，对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, without departing from the inventive concept of the present invention, some modifications and improvements can also be made, and these all belong to the present invention. protection scope of the invention.
